Data recently released by the U.S. Bureau of Labor Statistics reports that nonresidential constructionÂ continues toÂ boost the U.S. economy amid the residential downturn. Ken Simonson, chief economist for the Associated General Contractors of America (AGC), estimates that about 400,000 specialty contractors formerly working in residential have shifted into the nonresidential arena. Many of the concrete contractors I've talked to in recent months say they'veÂ had to shift to moreÂ commercial work to keep their crews busy. There are challenges in taking onÂ more commerical work, especiallyÂ if your company is set up forÂ mainly residential work. Whether you're performing traditional concrete work or decorative work, you'll find commercial jobs are larger and may require more equipment and employeesÂ on site to complete the job. With commercialÂ projects it'sÂ more likely you'llÂ work for a general contractorÂ than directly with the owner as you might onÂ a residential project. The bidding process is more involved inÂ commercial work. And you most likely will have to wait longer to get paid when working on commercial jobs. Have you been picking up more commercial work to stay afloat in the current construction market? What are some of the challenges you've faced with an increasedÂ number of commercial jobs?Â Do you have advice to offer other contractors looking toÂ take onÂ more commercial work? Post your comments to the blog -- I'm interested in hearing your thoughts!
