Of this group, 51 companies (26.3%)say they expect the U.S. constructionmarket will improve, 64 firms (33.0%)believe the market will decline, while theremaining 79 firms (40.7%) believe it willstay the same.

Many firms are monitoring closely thereports of recession in the U.S. “We’vebeen tracking the economy and trying togauge the potential impact of a reces-sion,” says Jack Scott, president of Par-sons Corp. “The commercial sector usu-ally feels a more immediate effect of adownturn, and we are already seeingsigns of a slowdown there.” He believes

500DESIGNFIRMS

FFor large design firms in the U.S., 2007 was a strong

year. But many firms increasingly worry that 2008

will be less robust as the U.S. economy teeters

toward recession and as financial institutions, blood-

ied by the subprime housing mortgage meltdown, look to be more careful in financing newprojects. Still, many large designers con-tinue to view the future with optimism asthey brace themselves for a few short-term bumps in the road.

The strength of the 2007 constructionmarket is clear in the volume numbers forfor ENR’s list of the Top 500 DesignFirms. As a group, they generated a totalof $80.62 billion in revenue last year, up

that a brief recession will only be a blipon markets, but a prolonged one couldhave a two-to-three year impact on theindustry. However, Scott says Parsonshasn’t seen any signs of a fall-off in itsmarkets.

For many firms, there are some signsof weakness in markets, but nothing dra-matic as yet. “The developer and mixed-use [building] markets have fallen off abit, but that is mostly regional in nature,”says Carl Roehling, CEO of Smith-Group. Adds Gordon Matheson, CEOof geotechnical specialist Schnabel Engi-neering Inc.: “We’ve seen a little slow-down in some of our markets, but noth-ing is falling off the edge.” So far the onlymajor casualty he has seen has been resi-dential, “and we got out of that market in2000 because of liability issues.”

As for public-sector markets, a lotdepends on local economies and tax rev-enue. “Everyone is watching for July 1,when most state budgets have to bepassed, to see the impact of any reducedtax receipts from an economic slow-down,” says Martin Koffel, chairman andCEO of URS. However, he doesn’t be-lieve that this year’s round of budgets willbe as bad as it was in 2002. “I think therewill be a slowdown in growth, but nomajor pullbacks,” he says.

Engulf and DevourOne of the big stories in the past year hasbeen an acceleration in the rate of consol-idation going on among the Top 500. Inall, 16 design firms disappeared from lastyear’s Top 500 Design Firms list throughacquisition. Another three firms nolonger appear under their own names,now incorporated into their parent firms’survey data. Among the year’s biggestacquisitions were: ABB Lummus Global,Bloomfield, N.J., by CB&I; VECO,Anchorage, Alaska, by CH2M Hill Cos.;Carter & Burgess, Fort Worth, by Jacobs;and Washington Group International,Boise, by URS Corp.

“We built this company as an engi-neering design firm,” says URS’ Koffel.But the firm saw the trend toward largerprojects and clients that wanted single

source delivery, he says. “Procurementdecisions are no longer made at the plantlevel but by senior career executives atthe corporate level,” he says. WashingtonGroup provided both self-perform con-tracting and solid engineering, plus entryinto growing energy markets for URS.“We now can provide services for thewhole project lifecycle, from planningand design, to construction, throughoperations and maintenance through ourEG&G division,” Koffel says.

As for continuing acquisitions, therealways seem to be firms on the table. “Weare always alert for tactic add-ons,” saysKoffel. But he doesn’t foresee anothermajor strategic acquisition in the imme-diate future. “It will take us a couple yearsto consolidate our acquisition of Wash-ington Group,” he says.

CH2M Hill’s acquisition of VECOwas another with strategic roots. “Ourfootprint in the energy markets wasn’tbig enough to make any real impact,”says Don Evans, CH2M Hill vice chair-man. VECO filled that need in bothpower and oil and gas sectors, just as

CH2M Hill’s purchase of LockwoodGreene a few years ago moved the parentfirm heavily into industrial markets.

Bargain Hunters from AbroadAnother factor that may be fueling thelevel of acquisition activity is the fall inthe value of the U.S. dollar against for-eign currencies. This effective devalua-tion has made acquisition of U.S. firms byforeign firms in high-value currencycountries a more enticing proposition.“The European companies are being par-ticularly aggressive in courting U.S.firms,” says Matheson. “Using Euros inthe U.S. is like getting 30% more foryour money.”

One successful European purchaser inthe U.S. was Scotland’s RMJM, whichbought architect-engineer Hillier. U.K.-based Balfour Beatty also has been in thehunt. “Balfour Beatty has always seen itshome U.K. market as core but now it andother European firms are looking at theU.S. as an extension of the core market,”says George Heitz, president of HeeryInternational, whose own firm was

acquired by Balfour Beatty 20 years ago.The Netherlands-based Arcadis also

has been on a buying spree, includingpurchases of major environmental firmsBBL, Syracuse, N.Y., and most recently,LFR Inc. and architect RTKL. “We areseeing many major clients in the environ-mental markets looking for vendor con-solidation, limiting bidders to the topthree to five firms in the industry,” saysSteve Blake, CEO of Arcadis U.S. “Ifyou’re not in that group, you are out ofluck. Our goal is to be a global leader inenvironmental services because it is trulya global market.”

The acquisition binge has had animpact on mid-sized and smaller firms.“We get offers to be acquired at leastonce a week,” says Schnabel’s Matheson.He says that acquisition is having a keyimpact in the competitor pool, notingsmaller competitors that have beenacquired are getting more aggressivelycompetitive. “They now have a largerorganization behind them, plus a largermarketing budget and lower overhead,”he says.

Global market changes are furtherintensifying competition in the U.S. “Weare seeing large international organiza-tions coming into the U.S. and becomingestablished in virtually every major city,”says Roehling of SmithGroup. He notesthe arrival several years ago of British-based architect Sir Norman Foster. “Now,Foster and Partners can do your design inDes Moines,” says Roehling. “This usedto be a local business with local relation-ships. Now, design is almost purely basedon expertise.”

An Old StoryFor some, however, consolidation is anold story. “Industry consolidation hasbeen going on forever,” says Paul Yarossi,executive vice president of HNTB. “Theonly difference is that now you have afew big public companies.” He claimsconsolidation has had a negligible impacton HNTB. “We still are able to competeon the big projects,” says Yarossi. “Plus,consolidation may be a plus as it bringssome publicity to the business.”

The consolidation trend is expectedto continue. “The public firms in theindustry have a whole lot of cash to spendand need things to invest in,” says Scottof Parsons Corp. “Plus, you have WallStreet demanding double-digit growththat the market can’t sustain. So acquisi-tion is the answer to increase size.” Butprivately held firms such as Parsons arealso looking long and hard at potentialbuys “because we use real money andexpect a real return,” says Scott.

Even so, there is still some industryskepticism on the acquisition trend. “Alot of the consolidation makes sense tothose who believe more is better,” saysTerry Neimeyer, chairman and CEO ofKCI Technologies. “But I fail to see thesynergies in many of these acquisitions.”He says many deals are simply exit strate-gies for aging executives of acquiredfirms. “I don’t see in many firms beingacquired that the leadership is young andaggressive,” says Neimeyer.

For many firms, acquisitions serve asecond purpose beyond expanding scopeand markets. Many firms believe it is the

fastest route to talent acquisition. “Weadded 25,000 people to our core of30,000 with Washington Group,” saysKoffel of URS. “And these are not justbodies, but top people with a breadth ofexperience and skills.”

Some design firm executives worryabout the impact of large corporate par-ents on the next generation of designers.Younger professionals “have bought intothe statistics that the average person willchange jobs 10 to 12 times during theircareers and are less willing to make long-term commitments,” says Roehling. Hebelieves that some of these younger peo-ple will be more attracted to working at large corporate design firms ratherthan wait and buy into more traditional-ly structured design firms as partners orprincipals.

Not everyone agrees with this assess-ment. “Young people are looking for funprojects to work on in a fun work envi-ronment,” says Heery’s Heitz. “We areseeing young people in their 30s expressinterest in firm ownership.”

The personnel shortage is causingmany design firms to develop more inno-vative personnel strategies. “People areworking a lot longer, often into their70s,” says Roehling. In many cases, ac-commodations can be made to retain em-ployees past the traditional retirementage, including working part time or onproject-specific jobs, he says.

It’s Easy Being GreenThe trend toward sustainable and greenbuilding has become less of a hot topicand more of a way of doing design.“Within 10 years, you won’t even hear ofthe issue of sustainability. It will simply bepart of the overall process of design,” saysJeffrey Gill, vice president of MCGArchitecture.

While sustainable building has beenbig in California’s public sector buildingsmarket, he says many of his firm’s com-mercial and retail clients that build toown for the long term are embracing sus-tainability to cut lifecycle building costs.California also is set to start forcing de-velopers to incorporate sustainable

design concepts, beginning in 2010, henotes.

There continues to be a cost premiumassociated with green building, so spark-ing interest in the approach among pri-vate-sector developers and other clients istough. “We put sustainability on the tablewith every client,” says James McManus,CEO of The S/L/A/M Collaborative.But many private sector clients seek in-centives to counter additional costs asso-ciated with green building. “So we havean arrangement with a consultant toaggressively pursue any available taxcredits or other incentives that mayreduce or eliminate the extra cost of sus-tainable design for the client,” he says.

“Green is fast approaching the cost ofentry in many markets,” says Roehling.SmithGroup has an initiative to have allfirm partners accredited under the Lead-ership in Energy and Environmental

Design (LEED) standards. “What will bemore challenging is the Architecture2030Challenge to have all structures carbonneutral by the year 2030,” Roehling says.

Integrated project delivery has be-come a hot topic for many design firms inbuilding sectors. “Construction is theonly major industry in the country that hasn’t improved the efficiency of its process in the past 30 years,” saysMcManus. Bringing the general contrac-tor on board early in the design processwas a good first step, he says. With thenew delivery approach, hiring of majorsubcontractors also would be expeditedso that design work could be donetogether under the owners’ supervision.

Using this collaborative approach anddigital building information modelingcan save time and money. “We take thedigitized model and share it with the fab-ricators in a form that is compatible with

their software,” says Kouhaila Hammer,CEO of Ghafari Associates. “This caneliminate thousands of shop drawings.”She says that working with all parties inthe construction process from a digitaldesign can reduce or eliminate aspectsthat don’t add value. Having a singleaccurate and collision-free design pro-vides subs and fabricators the freedom towork offsite, a plus in areas where laborsupplies are tight.

McManus says there remain road-blocks to the approach. “The owner mustbe an active participant,” he says, addingthat there are issues relating to ownershipand control of the digital design andquestions relating to liability. “However,architects are going to have to embracethis new technology and new approach toconstruction design or risk being relegat-ed to delineators or illustrators,” he says.

One big roadblock for BIM and digi-

tal design will be interoperability. “Rightnow, there are two major programs thatare incompatible,” says Heitz of Heery,citing the competition between theAutoDesk and Bentley BIM systems.“We’ve always been primarily a Micro-station firm, so we have tended to gravi-tate toward Bentley. However, we dohave offices that use AutoDesk, so com-patibility is an issue with us.”

Fill ’er UpWhile there is much concern about aneconomic recession, the petroleum mar-ket has been flourishing as oil prices con-tinue to establish all-time highs with noend in sight. “Gas and oil are very, veryhot and are taking up a lot of engineeringand construction resources,” says LenRodman, CEO of Black & Veatch.Robert Giorgio, president of CDI Engi-neering Solutions, agrees. “Projects usedto be on a take-it-or-leave-it basis. Asbusiness picked up, the contracts startedto be negotiated. Now they are on areimbursable basis,” he says.

But the hot petroleum market is notwithout its own set of headaches fordesigners. “Clients are under pressure toget the product out, and because they arein a hurry, front-end engineering isn’talways complete,” says Larry Wink, CEOof Wink Cos. This led Wink to do morefront-end engineering of its own. Thefirm currently is working on huge refin-ery expansions at Pascagoula, Miss., forChevron Oil, and at Garyville, La., forMarathon Petroleum.

Another problem Wink sees is anincrease in unrealistic expectations bysome clients. “We work well with ourbiggest customers, but there are someclients out there that aren’t as experi-enced and they expect error-free design,”he says. The firm has put extensive sys-tems in place to ensure quality, “but whena problem comes up, you have to stopeverything and explain or defend your-self, and that takes time and money. Youwant to know the price of perfection? Youcan’t afford it,” Wink says.

On the power side, the long-termmarket appears robust, but there are

the next five years and they don’t take itseriously.”

Gaining public and political supportfor infrastructure funding remains a keychallenge. “The problem is that infra-structure isn’t a sexy issue to politicians,”says KCI’s Neimeyer. He says such needsare clearly documented, but they take aback seat to other spending priorities.“Even when things go wrong, like the I-35 bridge collapse, infrastructure be-comes a hot issue only as long as it’s in thenews cycle,” he says.

Another problem is that the publicdoesn’t understand how infrastructurecontributes to the economy. “Historyshows that every time we as a nationmade significant investments in our infra-structure, whether it be canals or rail-roads or ports or the Interstate highway,our economy took off,” says Tony Bar-tolomeo, CEO of Pennoni Associates.He notes a Texas Transportation Initia-tive study released last September byTexas A&M University that concludestraffic congestion costs the economy $78billion a year. “Every dollar we waste dueto inadequate transportation makes us adollar less competitive in the world mar-ket,” says Bartolomeo.

Firms in the transportation sector arelooking ahead to 2009 when the federalreauthorization funding bill will beaddressed again in Congress. “The coali-tion to support reauthorization is buildingand seems stronger than the last time thefederal bill came up,” says HNTB’sYarossi. He is encouraged that all threepresidential candidates are talking aboutinfrastructure. “However, there is no sil-ver bullet to answer our transportationneeds—not the gas tax, not public privatepartnerships, or other plans. You have topiece together funding for each projectwhere you can find it,” Yarossi says.

The price of gasoline is having amajor impact on transportation funding.“With prices what they are, there’s nochance of getting an increase in the gastax,” says George J. Pierson, chief oper-ating officer of Parsons BrinckerhoffAmericas. Plus, many states get the bulkof their funding through their own fuel

some problems cropping up now. “Someof our clients are experiencing stickershock,” says Rodman. “They are sur-prised at costs pressures from the weak-ness in labor availability, materials priceescalation, and the short supply of equip-ment.” He says equipment manufacturershave decided not to get caught in thesame kind of oversupply situation similarto one that occurred during the last pow-er-market boom and bust, so they are notexpanding capacity. “This includes notjust turbines, but more mundane itemslike alloy piping, valves and such,” Rod-man says.

Rodman also is concerned about envi-ronmental opposition to coal-fired pow-erplants. “In the long run, the need fornew generating capacity will be enor-mous,” he says. “But there have beenabout a dozen coal-fired projects stoppedbecause of greenhouse-gas emissions.”Rodman says there is more flexibility insaving costs in designing a coal-firedplant than a gas-fired facility: “Will peo-ple be willing to pay the increased cost[for gas-fired plants]?”

Many firms are excited by theprospects of alternative energy, but someare seeing a fall-off. “A year ago, I wouldhave bet on ethanol as the key alternativeenergy source,” says Parsons’ Scott.“However, too many people got intoethanol on the speculative side and notenough are investing in it as a true sus-tainable energy source.”

Trillion-Dollar NeedsIn key infrastructure markets such astransportation, water and waste treat-ment, needs are so great that manydesigners express frustration that thepublic doesn’t understand the cost ofinvestment. “The public is so used torelying on their infrastructure that theytake it for granted, and are surprisedwhen something goes down like the I-35bridge in Minneapolis,” says DennisHirshbrunner, HDR executive vice pres-ident. “They see figures such as the $1.6trillion that [the American Society ofCivil Engineers] estimates we will need tospend to restore our infrastructure over

taxes. “Look at Florida and Texas. Peoplein those states are driving less to savemoney on gas and tourism is off, whichmeans fewer receipts from gas taxes. Butthat doesn’t mean needs are less.”

Many firms see a solid promise inpublic-private partnerships, but acknowl-edge that it will take some time for theAmerican market to accept it. “There isplenty of U.S. equity ready to be invest-ed and the numbers make sense for PPP,”says Blake of Arcadis. But he fears thatold habits die hard. “Foreign equityinvestors are used to working on a turn-key basis, but in the U.S., design-bid-build is still the rule in infrastructure,” headds. But Blake believes PPP will be amajor factor in funding infrastructure inthe long run.

Parsons Corp. is particularly interest-ed in PPPs. “It’s changing the nature ofthe market, particularly now in Canada,”says Scott. He says Parsons is taking partin PPPs as a joint-venture partner, ratherthan as a sub. “Rewards are potentiallygreater, but it changes your risk profile.Any job can go softwith a big number, soyou have to be reallycareful in who youteam up with,” Scottcontends.

For many engi-neering firms in the transportation sector,increased use of design-build has gener-ated new concerns. “With design-build,you are working for a different cus-tomer,” says Neimeyer of KCI. “Whileworking for a county or state agency,there always is a sense of urgency, it’snothing not like when you are workingfor a contractor.” He says that this oftenputs design firms in a difficult position ofsiding with the contractor on disputesagainst an agency knowing that the engi-neer will be bidding to represent thatagency on future projects.

For design firms, the revolution intelecommunications and technologypromised a 24/7 workplace, with designscirculated globally from the home officewhere high-end work is done to low-costcenters where drafting can be performed.

However, that vision has not quite cometo pass. “The 24/7 engineering modeldidn’t turn out as successful as we hadprojected,” says Pierson of ParsonsBrinckerhoff, echoing the feelings ofmany in the industry. Instead, PB is inte-grating its offices worldwide to allowcommon processes and easy access tointernal experts both at home and abroad,he says.

“With the new technology, there’s nolonger a need for a monolithic centraloffice,” says Giorgio of CDI. “Now, youcan have a series of smaller offices to actas centers for excellence in a specific areaor market.” He’s not alone in his assess-ment. “Technology is moving at a greatpace, allowing us to call on experts with-in the company on a moment’s notice toallow them to see the problem and gettheir advice,” says HNTB’s Yarossi.

For some firms, advances in telecom-munications have produced new marketopportunities abroad. “We’ve done threeprojects in Dubai from our Pittsburghoffice,” says Bartolomeo of Pennoni

Associates. “We did the high-level con-ceptual design in Pittsburgh, but the detailwork was done in India and shipped backto us for checking,” he says.

Softening Dollar The falling dollar has had an impact onthe competitiveness of U.S. firms ininternational markets. “U.S. designersused to be the big guys on the block whenit came to technology in the internation-al market,” says CDI’s Giorgio. “We arestill that, but now we are the low-costprovider as well, at least against some ofthe European competitors.”

However, Giorgio notes that firmsthat decided to farm out work to othercountries to save money are now experi-encing a little sticker shock of their own.“We opened up a Canadian operation as

“We are selling our services forless than the cost of financingthe projects we design.”

something of a low-cost center, but nowwith the Canadian dollar trading higherthan the U.S. dollar, we consider it aresource center,” he points out.

Shortages in trained staff may be alimiting factor for firms looking to theinternational market. “The falling dollarhas made us more competitive in foreignmarkets, but it’s not like we have all thisexcess capacity that needs to be sopped upby international projects,” says Evans ofCH2M Hill.

While the dollar’s falling value mayboost the competitive position of someU.S. design firms in overseas markets,others are worried about the trend.“There may be some competitive advan-tage in bidding abroad from the fallingprice of the dollar, but when you workabroad you are working using other cur-rencies, so the impact is not great,” saysRodman.

Some are worried about the dollar.“There has to be a correction or therewill be repercussions,” says Scott of Par-sons. He fears that the international com-munity may intervene or that the price ofoil and value of many currencies aroundthe world may be depegged from the dol-lar. Such actions would lower the com-petitive position of the U.S. economy asa whole.

Marginal MarginsScott contends that the engineering andconstruction industry “is probably a 3%to 4% margin business, and that hasn’tchanged in my 30 years in the industry.We had some of the smartest people inthe country working in this industry, butwe are selling our services for less thanthe cost of financing the projects wedesign.”

He adds that the industry should paymore attention to the bottom line and notbe stuck in the mindset that the only wayto increase it is to boost the top line, leav-ing little money left for critical invest-ment in research and development.Unfortunately, that will take a fundamen-tal shift in the attitudes of the industry asa whole. “We at Parsons can’t do it byourselves,” he concludes. m

The Top 500 Design Firms

Is the Boom on

DDespite the unease caused by the meltdown of the housing mar-

ket in 2007, ENR’s Top 500 Design Firms had a banner year. As

a group, the Top 500 generated revenue of $80.62 billion, up

15.8% from $69.61 billion in 2006. The prosperity was wide-

spread. Of the 459 firms on this year’s Top 500 that submitted

surveys last year, 382 enjoyed revenue gains in 2007, while 77

experienced declines and one remained unchanged. However,

these numbers are not quite as good as last year’s list, when 413

of the Top 500 increased revenue over 2005 and 50 saw declines.
