Thanks, Kevin. I'm going to start on pages 4 through 6. Thanks, everybody, for joining the call. We had a solid start to the year. We had record first quarter revenues of $1.9 billion and earnings per diluted share from continuing operations of $0.94. We had good execution in our business, and the year started out about how we expected. Strong performance from our Mechanical and Electrical Construction segments, continued improvement in our Building Services segment, strong performance in our U.K. segment, and still struggling performance in our Industrial segment. In our Electrical Construction segment, our operating income improved by 15.5% versus the year ago period. Operating income margins improved by 90 basis points, driven by better gross margins and tight overhead control. The Electrical Construction segment's improvement in operating income was driven by very good execution, with especially strong performance in the transportation market.
We also had very strong results for our customers in executing our commercial and healthcare projects. Our Mechanical Construction segment also performed well in the quarter. Operating income and operating income margins declined slightly. We had the headwind of a dispute settlement that aided operating income margins percentage by 90 basis points in the year ago period. Our Building Services segment had decent performance in the quarter, driven by our commercial site-based government and energy services business. We had improved operating margins of 50 basis points on improved mix. We had organic growth return to the segment and are in the successful implementation of several large contracts in our government and commercial site-based businesses, and have had record backlog in our mechanical services business. Our Industrial Services segment had a very difficult quarter.
We had previously discussed that we had a very tough compare in the first quarter of 2018 versus our outstanding performance in the first quarter of 2017. We did expect that tough compare, but it was even a tougher quarter than we expected. We suffered from a lack of volume in our turnaround businesses, which were driven by turnarounds that were planned and scheduled for the first quarter and pushed into later periods in the year and into 2019. We did have some shop rework and scheduling issues. We do expect performance to improve in the third and fourth quarter of 2018. I believe that Hurricane Harvey has altered the maintenance schedule for our customers, and I don't expect a normal resumption of demand until 2019. We have the resources, team, and capability to perform. We have, and we will again.
Our U.K. Building Services segment had a very strong performance, with operating income margins of 4.3% and operating income growth of 172%. Foreign exchange helped about 20% of this improvement, we had very strong conversion on our very strong organic growth. The remainder of this improvement was driven by that organic growth, better execution, and better mix. Our balance sheet remains liquid and strong, and cash flow was seasonally weak but was expected to be weak this quarter. We do expect cash flow to improve through the year and to be at least equal to net income for the year. We will have a full discussion of backlog and the changes to backlog, but on a basis comparable to previous reporting, we had backlog growth versus the year-end 2017 and close to flat versus the year ago period. With that, I'll turn the discussion over to Mark.
Thank you, Tony, and good morning to everyone participating on the call today. For those accessing this presentation via the webcast, we are now on slide seven. Over the next several slides, I will augment Tony's opening commentary and cover each of our reportable segments' first quarter operating performance, as well as other key financial data derived from our consolidated financial statements in Form 10-Q
Filed with the Securities and Exchange Commission earlier this morning. Let's revisit our first quarter performance. Consolidated revenues of $1.9 billion are up $8.7 million, or one-half of a percent over quarter one 2017. Incremental revenues attributable to businesses acquired of $19.4 million, pertaining to the period of time that such businesses were not owned by EMCOR in last year's first quarter, positively impacted our U.S. mechanical construction and our U.S. building services segments. Excluding such acquisition revenues, our first quarter revenues declined organically 0.6%. All reportable segments experienced quarter-over-quarter revenue growth other than our industrial services segment. U.S. electrical construction revenues of $454.8 million increased $11.8 million or 2.6% from quarter one 2017. Quarterly revenue growth was primarily driven by project activity within the healthcare and institutional market sectors, partially offset by quarter-over-quarter declines in revenues from transportation construction projects due to certain project completions.
U.S. mechanical construction revenues of $698.8 million increased $27.7 million or 4.1%. Excluding acquisition revenues of $10.2 million, this segment's revenues grew 2.6% organically quarter-over-quarter. This segment's revenue growth was primarily driven by higher project activity within the commercial, healthcare, and institutional market sectors, partially offset by a decrease in revenues from manufacturing construction projects. EMCOR's total domestic construction business first quarter revenues of $1.15 billion increased $39.5 million or 3.5%, of which 2.6% of such growth was generated from organic activities. U.S. building services revenues of $454.8 million increased $14.7 million or 3.3%. Excluding acquisition revenues of $9.2 million, this segment's revenues grew 1.2% organically quarter-over-quarter.
Revenue gains within the mechanical services division due to increased project and repair services activities, as well as large project activity within their energy services offerings, were complemented by increased snow removal activities due to more seasonal winter weather in the geographies which we currently service. These revenue gains were somewhat offset by the loss of certain contracts not renewed pursuant to rebid during 2016 within the commercial site-based services division that were still transitioning in early 2017. U.S. industrial services revenues of $185.1 million decreased $73.4 million or 28.4% due to a reduction in executed turnarounds within the first quarter as our customers have altered their previously scheduled maintenance activities due to the residual impact of Hurricane Harvey. The reduction in field services revenues also negatively impacted our shop services due to the reduction in repair service opportunities that typically result from a normal spring turnaround season.
United Kingdom Building Services revenues of $106.9 million increased to $27.9 million or 35.3% as we continue to see the operating benefits of new service contract awards, as well as the resumption in some level of add-on project activity. This segment's quarterly revenues were also impacted by $12.5 million of favorable foreign exchange movement. With regard to the impact on financial performance comparability due to EMCOR's adoption of Accounting Standards Codification Topic 606, the new revenue recognition standard, in which we elected to adopt utilizing the modified retrospective method, our reported first quarter revenues were favorably impacted by approximately $900,000, which represents less than 1% of quarterly revenues. Full disclosure is provided in footnote number three in our notes to condensed consolidated financial statements included in our Form 10-Q filed earlier today. Please turn to slide eight.
Selling general and administrative expenses of $190.3 million represent 10% of revenues and reflect an increase of $7.3 million from quarter one 2017. The current year's quarter includes approximately $2.2 million of incremental SG&A, inclusive of intangible asset amortization from businesses acquired, resulting in an organic quarter-over-quarter increase of approximately $5.1 million. This increase is primarily due to higher employment costs as a result of increased headcount to support our organic revenue growth in our construction and building services segments, as well as higher incentive compensation expense. The 30 basis point increase in SG&A as a percentage of revenues is due to the company's expectations of higher earnings for full year 2018 versus 2017 at both the consolidated and segment reporting levels, which necessitates higher annual and long-term incentive compensation accruals and related expenses within the quarter.
This fact, in concert with only a slight increase in revenues overall during the current year's first quarter, is somewhat distorting the first quarter SG&A percentage. In addition, our SG&A as a percentage of revenues was negatively impacted by unabsorbed overhead costs within our industrial services segment due to the lack of significant turnaround activity. Reported operating income for the quarter of $78.7 million represents 4.1% of revenues and compares to $82.8 million or 4.4% in 2017's first quarter. Our U.S. electrical construction services segment operating income of $35.9 million increased $4.8 million or 15.5% from the comparable 2017 period. Reported operating margin of 7.9% represents a 90-basis point improvement over last year's first quarter. The increase in this segment's operating income is due to increased gross profits from project activity within the transportation, commercial, and healthcare market sectors due to either increased volumes or improved project execution.
2018's first quarter U.S. mechanical construction services segment operating income of $39.6 million represents an $861,000 decrease from last year's quarter. Reported quarterly operating margin is 5.6%, which is 30 basis points lower than 2017's first quarter. Despite the quarter-over-quarter reduction in both operating income and operating margin, this segment had strong performance across most market sectors served. However, 2017's first quarter benefited from the recovery of certain contract costs that were incurred in 2016 that were previously disputed. The recovery of such costs, which we disclosed last year at this time, had a 90 basis point favorable impact on this segment's 2017 first quarter operating margin, and Tony obviously previously mentioned this as well. Our total U.S. construction business is reporting a 6.5% operating margin for the quarter as compared to 6.4% in last year's first quarter.
Operating income for our U.S. building services segment of $17 million represents a $2.8 million improvement from last year's first quarter, while reported operating margin of 3.7% is increased by 50 basis points quarter-over-quarter. The increase in operating income and operating margin year-over-year is due to improved operating performance from their commercial site-based energy and government services divisions. A combination of improved project mix with a somewhat normalized winter weather pattern, which resulted in increased snow removal activities, were the factors driving quarter-over-quarter improvements. Our U.S. Industrial Services operating income of $3.5 million represents 1.9% of revenues, which is a decrease of approximately $13.6 million from 2017's first quarter. The reduction in quarter-over-quarter performance within our industrial services segment is due to the continuation of challenging market conditions, exacerbated by the impact of Hurricane Harvey, which has altered our customers' planned maintenance schedules.
This has impacted both our field services operations due to reduced turnaround activity, as well as our shop services, which can potentially benefit from pull-through repair work opportunities and therefore absorb some of the fixed overhead costs within this segment. U.K. Building Services operating income of $4.6 million represents 4.3% of revenues, which is an increase of $2.9 million and is a 220 basis point improvement over last year's first quarter. Our U.K. team continues to do a good job of securing and executing new service contract relationships to augment their historical maintenance base while seeing some resumed small and capital project activity within the first quarter. We are now on slide nine. Additional key financial data for the quarter not addressed on the previous slides are as follows.
Quarter one gross profit of $269.1 million represents 14.2% of revenues, which has improved from the comparable 2017 quarter by $2.8 million and 10 basis points of gross margin. This quarterly improvement is due to higher gross profit and gross margin across all of our reportable segments other than U.S. Industrial Services, which was down substantially quarter-over-quarter for the reasons previously discussed. Diluted earnings per common share from continuing operations is $0.94 and compares to $0.88 for the quarter ending March 31st, 2017, which represents a 6.8% increase. Our tax rate for the first quarter of 27% is lower than expected due to favorable discrete items recognized within the quarter. Our expectation for a full-year tax rate remains consistent with my commentary provided in February of a range between 27.5%-28.5%.
Until interpretations of the enacted federal law are finalized by the various state taxing jurisdictions in which we operate, we will not be in a position to narrow our current tax estimate range. Lastly, on this slide, we used $59.1 million of cash in operations during 2018's first quarter with the funding of our prior year's incentive compensation awards occurring in February and March. Quarter one historically represents our weakest cash flow quarter of each year. We are now on slide 10. EMCOR's balance sheet remains sufficiently liquid, as represented by cash of approximately $352 million, and modest leverage is demonstrated by our debt to capitalization ratio of 15.4%. Our cash is reduced from year-end 2017 due to both the cash used in operations previously referenced, as well as $45.3 million of cash used in financing activities, which included $34.5 million of share repurchases during the quarter.
Working capital levels have increased since the end of 2017 due to a reduction in current liabilities as a result of reduced levels of accounts payable and accrued payroll and benefits due to the funding of prior year obligations. Goodwill has increased slightly due to true-up payments made during the quarter for assessments made to the purchase price of an acquisition completed in late 2017. Identifiable intangible assets have decreased solely due to the quarterly amortization of expense of approximately $10.7 million. Total debt is approximately $307 million, with a reduction from December 31st due to the mandatory quarterly principal repayments of approximately $3.8 million of our outstanding term loan. We are happy with where our balance sheet is for this time of year, and we continue to be well-positioned to capitalize on future opportunities available during this continuing strong market cycle.
With this portion of my slides concluded, I would like to return the presentation to Tony. Tony?
Thanks, Mark. I'm on page 11, which is Backlog by Market Sector. Total backlog at the end of the first quarter was $3.95 billion, just about flat against the first quarter of 2017, and up $154 million from December 2017. Our backlog levels remain fairly high given our strong revenue performance for the quarter. Non-residential construction demand remains positive across most sectors and geographies, generating nice opportunities for our EMCOR companies. Similar to what we said in late February, we think the non-residential market will grow in the 3%-5% range this year. Let me focus a little bit now on market sectors. Commercial project backlog continues to be strong. Commercial backlog represents 43% of total backlog and increased both year-over-year and since December.
Demand is widespread across the company. We think the commercial sector should continue to be active for us into the front of 2019, as judged by the bidding opportunities we are currently seeing. Project backlog associated with water and wastewater projects also grew both year-over-year and year-to-date. We are positioned well really in many parts of the country, but this specifically is with our Poole & Kent subsidiary in Miami, that historically has performed significant water and wastewater projects in and around the Greater Miami, really the Greater South Florida area. Miami-Dade will be investing heavily against a consent decree in its water and wastewater infrastructure over the next five years. We have already won a number of large projects. We expect to be in the running for more as the work comes out and is awarded.
We have other subsidiaries at EMCOR that participate in this market, and if it becomes active as it is in South Florida, as part of a broader infrastructure push, we will be there to take advantage of it. I'm now on page 12. As you saw in the market sector growth graph, backlog year-over-year was basically flat with some market sectors up and some down, but overall a very good market with good opportunities for us to win. However, an interesting note here, every one of our segments had backlog increases from December 31st, 2017. For the first three months, domestic backlog was up $128 million or 3.5%. Our domestic construction segments increased backlog $70 million, while our building services segment backlog also grew $57 million or close to 8%. Building services backlog grew in both the commercial site and mechanical services businesses.
In fact, mechanical services backlog increased in each of the first three months of 2018 and now is at its highest level at approximately $372 million. As you would expect, commercial projects comprise much of this backlog. I'm now going to turn the presentation back over to Mark, and it'll be on page 13. On January 1st, and Mark talked about this, we adopted the FASB's new revenue recognition standard, which requires the disclosure of remaining unsatisfied performance obligations. We ought to be able to make up an acronym out of that, right, Mark?
Yes.
It is covered on page 27 of our 10-Q. I'm now going to turn the presentation back to Mark and have him walk through the new standard and its impact on EMCOR, and we're now on page 13.
Thank you, Tony. As I mentioned earlier during my financial review commentary, EMCOR adopted Accounting Standards Codification Topic 606, or as referred to ASC 606, the new revenue recognition standard as of January 1st. Even though this new accounting standard did not have a material impact on our first quarter operating performance, it has necessitated a change in how we quantify and report our estimate of future activity related to our contractual arrangements with our customers. ASC 606 requires us to identify if we have a contract with the customer, and if so, we then have to identify our performance obligations under such contract.
To the extent we have not fulfilled all contractual performance obligations at the end of a reporting period, we are now required to quantify and disclose under generally accepted accounting principles, remaining unsatisfied performance obligations by allocating a portion of the contractual transaction price to those performance obligations not yet completed. Although definitionally this sounds a lot like our historical backlog disclosure, it is not the same. The primary difference between remaining unsatisfied performance obligations and backlog, as historically defined by EMCOR, is the evaluation and quantification of the remaining term of our multi-year service contracts. Under our previous reporting, we had quantified the base level of maintenance services to be executed for the success of 12 months without any quantification for increases in contract scope or potential project opportunities.
We honestly were quite conservative in this determination relative to other companies in our broader industry that reported a backlog figure. Under the new accounting standard and related transitionary guidance, if a contract gives each party the unilateral enforceable right to terminate the remaining unperformed contract without compensating the other party, the amount of unrecognized revenue within the remaining performance obligations is limited to the notice period required for such termination. Most of our service contracts contain unilateral termination for convenience clauses with varying notification periods. As a result, we had to exclude approximately $545 million of unrecognized revenues from our remaining performance obligations disclosure, predominantly related to the impact of termination clauses on contracts within our U.S. building services segment.
This reduction was partially offset by approximately $203 million of incremental performance obligations pertaining to unexecuted contracts, for which we expect to receive fully executed contract documents in the ordinary course of business, as well as certain variable consideration items. This information is fully disclosed both in footnote three in our notes to condensed consolidated financial statements, as well as within item two, management's discussion and analysis of financial condition and results of operations within our Form 10-Q, as I mentioned, that was filed earlier today. As backlog is a term not defined under generally accepted accounting principles, and remaining unsatisfied performance obligations is now a required GAAP disclosure, we will only speak to remaining performance obligations during future earnings calls and provide a quantitative and qualitative narrative from a sequential perspective until we have a full four quarters of our reporting history.
With that exhaustive explanation concluded, I will now let Tony return to our closing slides. Tony?
Yep. Thanks, Mark. My closing comments will be on pages 14 and 15. We're going to reiterate our guidance of $4.10-$4.70 in earnings per diluted share from continuing operations. This earnings per share guidance incorporates an estimated tax rate of 28% post-tax reform. We expect revenues of $7.6 billion-$7.7 billion. When we gave our initial guidance, we expect to continue growth in the non-residential construction market, decent demand for our government and commercial site-based services, a strong energy retrofit market for small projects especially, and a choppy and less predictable market with respect to our downstream refinery and petrochemical market, mostly due to Harvey. At least through the first quarter, those underlying drivers are consistent with what we believed when we set our initial guidance.
We expect more clarity in the downstream refinery and petrochemical markets as we approach mid-2018 for both the fall turnaround season and 2019. We still believe we will gain better clarity as the turnaround schedules firm up for fall 2018 and the spring 2019 turnaround seasons. As always in these calls, we provide a view of what needs to happen for us to move to the mid to the top end of our guidance range. Here they are. We need to continue to perform at a high level in our U.S. construction segments. We do have some headwind in the second quarter as we benefit from significant claim and dispute settlements in 2018 overall. We discussed those in our 2017 10-K and year-end call.
However, as we have shown in the first quarter, we continue to perform at a very high level in the electrical and mechanical construction segments. We continue to have strong operating income margin performance. I just want to remind everybody of something. We have a very tough compare in the second quarter in our mechanical construction segment versus the second quarter in 2017, and we had a significant dispute settlement, and it was almost $12 million in the second quarter of 2017, and that was all fully disclosed in both our K and our Q from last year. Our U.S. building services segment finally had organic growth in the first quarter, and we're implementing several new site-based contract wins.
We're growing our mechanical services business, and we expect to execute well for some Department of Defense and other federal agency customers as they need to repair these facilities were in bad shape, that were impacted by sequester, and now they have money, and they're going to reprioritize their budgets. We should benefit from that. We had strong operating income margin expansion in the first quarter in building services, and we expect that for the year. Our industrial segment will improve in 2018 versus 2017, but it'll be weighted to quarters two through four, really quarters three and four. We had a very weak first quarter. We do see more opportunities for us as the year progresses. As Harvey has decimated the segment in the third and fourth quarter of 2017, our comparisons are much easier then.
For us to move to the top end of the range, we will need some increased scope on the turnarounds that are planned in the end of the year, also some unplanned event that we don't have as of today. Certainly, it's possible, and these unplanned events have happened more than a few times for us over the past 10 years. Our U.K. business had a strong first quarter, and the segment's performance continues to improve. We expect to have decent cash flows this year, and they should be at least equal to net income. We will look to use our cash and balance sheet to grow organically and through acquisitions, and we'll invest acquisition capital in any of our domestic segments. We'll return cash to shareholders this year through buybacks and dividends.
In the first quarter, we returned $39 million in cash to our shareholders through buybacks and dividends, with about 88% of that return cash executed through buybacks. We prefer buybacks versus dividends for any incremental return of cash to shareholders. We like how our businesses are positioned. We performed well in the first quarter. In summary, we expect to continue to deliver for our shareholders in 2018. With that, I'll turn it to Adam for questions.
Once again, ladies and gentlemen, if you would like to ask a question over the phone lines, that is star 1. Your first question comes from the line Tahira Afzal with KeyBanc Capital Markets.
Hi, folks.
Good morning, Tahira.
Morning. Tony, I guess the first question is, we've started to see, because I cover some of these bigger E&Cs that are focused on petrochem and LNG, there seems to be suddenly a lot of movement on these projects moving forward again. I know you've commented on some of the downstream maintenance aspects, in terms of small CapEx, should that not bode well for your industrial segment as well?
Yeah, I think as you move through 2018 into 2019, I think that's true, and I think that's true for midstream also, especially in our electrical segment. We don't perform a lot of new build work on the LNG and petrochem. We will now electrically, especially in the Corpus Christi area. Mechanically, that's not something we do a lot of. Also, you got to remember, especially on the mechanical side, a lot of the EPCs will try to self-perform some of that work, until they can't self-perform that work. That's when I talked about the unplanned events.
Right
That tends to be when we get involved, is when they can't finish the work and marshal the resources.
Okay. If I was to look at all the unplanned events that could happen that provide upside, which are the ones you think are high probability? Typically, if I was to look at the way my model's planned, it seems like maybe there's some conservatism still around electrical and mechanical. Would you say that really the probability of some of this maintenance or small CapEx work could be the really bigger mover?
Yeah, I think two places. I think it's very rare for us to have a significant unplanned event in mechanical or electrical segments because those projects take a lot of planning. Also, if we're reacting there, it's usually on a time and material basis, which with those workforces in those markets, are a little different. Unplanned events can happen in the building services segment, IDIQ work, something can go significantly wrong with a customer facility, we have to jump in and do it.
Right.
The largest unplanned events happen in the industrial segment. It's usually on, we have to help complete work on a capital project that is coming right up against where liquidated damages come into play, or a maintenance event that a lot of this deferred maintenance comes home to roost, and we like to say, we have to flood the zone, right? We have to get a lot of men and women up and running very quickly, mobilized and ready to work. That can happen. It can happen from things where the facility had to shut down, or it can happen from things where the facilities hit a significant bottleneck because of the performance of part of the plant, and now it needs de-bottlenecked or a specific part fixed in a very short period of time, usually because some planned maintenance wasn't performed in an earlier turnaround.
Got it. Okay. That's helpful to know. Tony, I guess last question. The economy has been doing well for several years. I know you're a little more late cycle, but are we seeing a point where the labor is tightening? Are you getting pricing or is that something you think is a concern going forward?
Well, look, price is better than it was three years ago, clearly. We're not winning on the margin side right now because of price. We're winning because of execution. I would say we're further out on the labor curve than we were. We're way beyond our core guys and the core folks that work for us. Training's more important, selection's more important, screening's more important. Labor is tightening. That's a good thing. More people are coming into the workforce. More people are coming back into the workforce. We're still, I think always will be, a destination of choice for craft labor and skilled trades people. Labor is likely to be available to us that's not available to other people. Pricing's been okay, actually, both in the non-union and union workforces.
We haven't seen really sizable increases beyond what you'd expect 2% or 3% a year. In the contract negotiations, we negotiate on the union side multi-year agreements, and quite frankly, people have been quite reasonable this time around.
Got it. Thank you, Tony.
Your next question comes from line of Noelle Dilts with Stifel.
Morning, Noelle.
Hi, good morning. Just kind of focusing on the turnaround business a bit. We've obviously seen some of these sort of deferrals or push-out of work at some of your competitors over the years. You guys were kind of lucky for a period. I shouldn't say lucky, but you guys definitely didn't see some of that for a couple of year periods. I just want to kind of dig into what gives you the confidence that what you're seeing now is sort of Harvey related versus related to just some other factors and general deferrals?
Let's go up a level. I think the luck came from having great resources that could handle very large-scale projects on very short time frames, and it allowed us to weather some of the decreases in plant turnaround activity.
Right.
Those opportunities, we believe, will present themselves to us again, and we'll be there to take advantage of them. I think there are some things that have changed, right? Versus maybe five or eight years ago in the turnaround business. I think one of them is the Permian Basin and West Texas crude. It's less sour, it's less viscous, and as a result of that, when all these facilities were outfitted in the mid-2005, 2004, 2005, 2006, 2007, 2008, when there was a lot of capital going in. They put equipment in and heat exchangers and other things, and up alloyed that was based on running really crappy crude out of Saudi Arabia, Venezuela, and Canada.
That mix has shifted to more West Texas, and they're still trying to figure out what the right mix of maintenance is to go with that and shift the mix. Our belief, and not Tony, Mark, Kevin, Maxine's belief, but the people that are in there every day, that they're probably extending that cycle or not doing enough maintenance. You're starting to see that around the edges as some of these refiners have unexpected turndowns of their facilities and other things. The second thing that I think is a shift is there's been consolidation. To make their contracts now, they can look at bigger parts of their fleet, right? One of the big majors got out of a lot of the refining business. Someone bought their facilities, others have swapped assets.
They're able to optimize their fleet of refineries better to meet their take contracts on the way out. I think those are two of the big things you'd say. Has that shifted demand patterns? You'd say, "Yeah, maybe that has." The other thing you can't discount, though, is what's going on in the petrochemical market. How do you fill that in? Well, underlying all this, and this part was probably more affected by Hurricane Harvey, at least in EMCOR's case than the refinery business is the petrochemical market. That has become a fairly significant business for us, as some of our larger turnarounds over the last three years have been done in petrochemical plants, not in refineries. As a result of that, we think that business doesn't have the same characteristics that I talked about with what's happened with the refiners.
Some of that's happened. I think you have to have the capability that we have to be able to react to your customers' demand. It's a balancing act for someone like us to keep the foremen and the superintendents and all that, even though we may not be as busy in the first quarter as we would like to have been or had planned to be, because once you lose some of those very valuable resources, you may not get them back. That doesn't allow us then to do what we did in 2016 and the first half of 2017, if in fact, we don't have those resources. There might be a drag of $1 million or $1.5 million in the P&L at any given time if those resources aren't fully deployed, because we're not absorbing the overhead.
Mark, everything about right? Does that help, Noelle?
Yeah, that's actually great. Those are a lot of good points that you make. I guess, just shifting to my second question, just in terms of M&A opportunities and potential targets that you're seeing out there. In the past, you've talked about valuations being a little bit steep. Can you just talk about what you're seeing in the market right now and your general appetite for M&A?
Look, our appetite's what it's been, right? We think we're pretty good acquirers. We're selective acquirers. Market fit, capability, and culture are all three things we look at before we'll just jump in and buy a company. We expect a fairly decent year this year in M&A, what I like to call is, for lack of a better word, somebody's life's work. Somebody that built a great company, the Newcombs, the CCIs, the North Stars. They built great companies. They're now in their mid-50s, and they want to sell their company.
They still want to work. We do very well with those transactions, and we see a decent pipeline of those type of transactions here in 2018. Now, when they get done, how they get done, what's the timing of those, I don't know. Some of these conversations have been going on for years. People have had a couple good years behind them. They've recovered from the recession. Their balance sheets are strong. Their project outlook's strong. They've rebuilt their market positions. In a lot of cases, they've hired the next level of management, and they professionalized their companies as we've gotten to know them over five or 10 years. We've helped coach them to do some of that stuff. Private equity, you get to the larger deals pricing is still a little crazy, right?
We just looked at a couple things this year, which we would've put in the category of pretty significant fixer-uppers, that we thought we could make work and would've taken us some time and resources, and we have people that know how to do that, obviously. We know how to do that collectively as a team. When we get to what they're really making versus their pro forma making, we can't get to a deal, and then the advice we get from the people selling it is, "Well, don't put your pencil and paper away yet. We may be back to talk to you." Geez, Noelle, on some of those things, our valuation for some of those assets is 30, gosh, 50% below what it may actually trade at.
I doubt somebody knows more than we do about what they're going to do with it and those particular assets. We're going to be responsible. Last year, we did $107 million worth of acquisitions. They've all fit in really well. They're all doing well. A couple years ago, we took advantage of a cyclical low and bought Ardent. Had a decent first year, had a rough second year because of the market. Ardent and Rabalais are positioned well as upstream comes back. When the things happen on the Gulf Coast, especially talk about petrochem, and you talk about what could happen in Corpus Christi, we're really happy we own them. Is it going to be all of 2018, but as we move into 2019? I think we're going to continue to do what we always do. Look for places that fit. We still have geography.
We certainly would like to fill in more electrical geography on the commercial side and data center side, and we'll see what happens there. We certainly have people that we have partnered with in the past that could be good acquisition candidates. If we can't make the right acquisitions, we'll return cash to shareholders as the year progresses.
Thanks. That's really helpful.
Your next question comes from line of Tate Sullivan with Sidoti.
Hi. Thank you. Good morning. Mark, can you talk more about the cash flow statement? Just it looks like the outflow, the cash flow from operations outflow was a bit larger than it was in previous first quarters. Did you pay more of your payables than you usually do? Also, it looks like there's some line items about payments for businesses acquired, but I think you said you didn't acquire anything in the quarter.
Yeah. Tate, I'll address the last question first, then I'll work backwards. The payments for businesses that were recorded in the first three months of this year were related to contingent consideration arrangements for two transactions that closed in the last year, so our earn-out arrangement.
Okay.
No new companies, just continuation of transactions that happened prior to 2018. With regards to the variation in operating cash flow of 2018 versus 2017 through March 31st, there was a larger outflow of payables in the first quarter. The biggest two things really are on the inflow side. First and foremost, as Tony had mentioned during his commentary
We were successful in resolving a contractual dispute in quarter one actually continued into quarter two. That customer had not rendered any payments in the fourth quarter of 2016. All that money was received in the first quarter of 2017. Additionally, because of the significant reduction in volume within our industrial services segment, there was just no customer activity there at all. Fall turnaround, because of Hurricane Harvey, was significantly impacted. Billings that we typically would have gone out prior to December 31st and would have been collected in the first quarter of the calendar year, did not happen in the first quarter of 2018 because those billings just weren't there. Obviously, we were much stronger in that segment, both in the back half of 2016 into the first quarter of 2017.
It's an unfortunate situation, at the end of the day, it's nothing to be concerned about. We're very confident that we're going to be a significant cash flow generator in 2018, as we have been for a long number of years. It's just, we got off to a slow start. To be quite honest with you, first quarter of 2017 was artificially good relative to our history, if you actually took the time to look back. We're typically negative in the $35 million range through the first three months of the year.
Okay. Great. Thanks. Tony, you talked about mechanical having a poor comp in 2Q because of the settlement. I calculate mechanical margin in 2Q 2017 was about 7% with that settlement. What are you looking at for that business?
Well, I don't give quarterly margin projections, but 7% is high, and I think I said that last year and said it wasn't a sustainable margin at that point. Look, I didn't say a poor comp, I said a tough comp. I think we'll still do well in the second quarter of mechanical, but it'll be very difficult for us to make up for $12 million of settlement and then help those margins get to 7%.
Okay. It was $12 million. That's right. Okay. Well, thank you very much.
You're welcome.
Your next question comes from line of Adam Thalhimer with Thompson Davis.
Adam, how are you?
Good morning, guys. Congrats on a good quarter.
Morning. Yeah, thank you.
Hey, Tony, your domestic construction backlog was down for the second straight quarter. How concerned are you about that?
We're not. Versus year-end, it's okay. We have a lot of bidding opportunities, and we expect to do fairly well in our construction business this year. No concern at all.
Okay. You said you think the overall market grows 3% to 5%, but just trying to parse through your guidance. It looks like you're forecasting domestic construction revenue kind of flattish, maybe even down a little bit. Do you think you kind of underperformed the market this year just with tough comps?
No, I think we did real well last year, but I think for us to get to $7.6, $7.7 with the start we had in industrial, we need a pretty good rebound for the rest of the year. I think construction will be more than okay, and I think we have a really good mix right now.
You think construction could grow with the industry, that 3%-5%?
Yeah. It [may turn out to be] this year or the next year, but we don't really know how much more revenue. We had good acceleration of revenues in the fourth quarter last year, right?
Yeah. We actually had a couple of projects due to weather in the first quarter of 2018 that actually work was suspended. We'd like to think we're going to get caught up with that work before the end of the calendar year, but some of it actually might tail into the first quarter of 2019. Just don't know yet.
The biggest issue in construction is what we talked about in the comp in mechanical. Between those two quarters, we picked up almost $18 million of profit with no revenue. As a pretty big project, you have to go file-- pretty big chunk of revenue.
Revenue with no cost
revenue, no cost.
Yeah.
You got to go find a pretty big chunk of revenue to make up for that, right? That is the biggest issue in construction this year. The underlying business is performing very well, and in fact, it even performed better than what it looks like when you add back that $6.5 million in the first quarter. The good news about us is we told you all that last year, and we told you all that this year, and so there's no surprises, right? The underlying business is very strong.
Adam, this is Mark. The only thing I would add to that, in light of your question with backlog. Clearly, in the transportation sector, a lot of those projects, which are continuing to burn, were large multi-year contracts. Those types of things aren't added into backlog on an annual basis or on a quarterly basis. The good thing was we had them, and the good thing is we're executing well on them, but unfortunately, as they burn, how that gets replaced typically gets replaced in smaller increments as opposed to big chunks.
It'll be a big chunk sometime, and then I think the same thing on the food process side. We finished a lot of our big food process work last year in the fourth quarter. We actually thought we would be finishing it in the first half of this year. We accelerated it. We didn't accelerate it, our customers actually asked us to accelerate that work so that they could get those plants into revenue-producing mode sooner rather than later. We're working on some very nice projects there, but they get awarded when they get awarded. You're working with boards and cooperatives and all kind of different folks to get that approved. They're significant capital investments, and they'll happen when our customer's ready to say they're ready to go. We'll be there to execute it, and you'll see a jump in backlog when that happens.
When you see a big jump in backlog with us, like right now, this is the underlying business is just running. Right? There's some big projects, $60 million, $70 million, $80 million projects in there. There's a lot of $1 million, $2 million, $3 million projects running in and out, running through there. When you see our backlog jump, it typically means that we have a significant multi-year project that's been put into backlog. We talk about that. You don't see jump with the day-to-day business because we're executing at the same time we're putting things into backlog on that work. I think the average size of our project is still, what Mark, a million bucks, a million and a half dollars at EMCOR? That's still the average size of what goes on here.
Okay, because some people that we follow have talked about a moderation in the growth rate of non-res. Still growth, but maybe going from five down to three or something like that. I'm just curious.
Yeah, I don't know. It could be more civil related or something.
On the front end of the cycle as opposed to where we are.
Yeah, we're further down this path.
Yeah.
That could be coming for us.
more late cycle than some others.
Adam, this is Kevin. If you look inside some of those numbers, the commercial markets, the building market, the educational market, they are all running hotter than some of the other markets that the other guys are talking. That's where we have the largest part of our backlog.
Yeah, you could see the power market turn down year-over-year.
Right.
That really wouldn't have much of an impact on us.
Okay, I'll turn it over. Thanks, guys.
Thank you.
I'll now turn it back over to management for closing remarks.
Okay. Thank you. There are a couple things I hope you took away from the call. We're excited about the start. We're going to talk about in the future, instead of historical backlog, we're going to talk about remaining performance obligations. I'd ask you to go back and refocus on page 13 and read page 27 of our Q. We think it's better just to put a stake in the ground and move from there. This will be a GAAP number. We think it's better to talk to the GAAP number. The final thing is, the business is in really good shape, and we need the industrial market to recover, which it surely will over the next six to 18 months. Thank you all very much, and everybody be safe.
This concludes today's conference call. Thank you for your participation. You may now disconnect.
