The time between receiving bids (or a proposal for sole source work) and the start of construction is a busy time for the contractor, the owner, and the design professional. The design professional must quickly check the bids and verify that the low bidder truly has the qualifications to do the work, then prepare the contract documents for signatures. The owner needs to proceed through the necessary steps to award the project, which include having financing ready. The low bidder must begin to expand upon the data assembled during the bid phase and prepare for mobilization.

The American Society of Civil Engineers (ASCE) includes Levees on its 2009 Report Card for America's Infrastructure, giving them a D–. The category of "Levees" covers major flood control works. However, what about the water that causes the flooding that levees protect against? Throughout drainage basins comprising thousands of square miles, stormwater runoff makes its way downstream. Obviously some systems convey that stormwater and even control it. ASCE says nothing about these storm sewer systems, but they form a vital part of America's infrastructure.

To maintain a project's schedule, productivity, and ultimately, profitability, it is imperative that the job foreman and the office project manager and/or estimator are aware of weather and site conditions.  During this time of the year, material delivery becomes an extremely important part of maintaining project schedules and minimizing surprises.

Specifiers tend to create their products based on what manufacturers tell them.  This is not a bad idea; after all, no one has the time to research all the products used on site.  Manufacturers will indicate that their materials need to be pre-conditioned to the interior temperature for a period of time, usually 24 hours prior to installation.  The standard temperature is typically between 55 degrees Fahrenheit and 70 degrees Fahrenheit.

What is the best way for a construction observer to train? Learning from a professional on site may be ideal, but other good sources of information include public agencies and the documentation they make available.

Columnist David A. Todd, P.E., CPESC, has 37 years of experience in the architecture, engineering, and construction (AEC) industry and has performed much construction administration during that time. He will answer questions from our readers or from his own practice and will provide answers based on his understanding of the construction process.

Not a day goes by when we don’t get bombarded with more talk of jobs, be it from politicians or the media. It seems that this is the single most important factor on which we must base all decisions. City, county, and state budgets are depleted, but we continue to allocate tax payer money to economic development strategies that have proved too costly and ineffective. Economic development has, for the most part, become a mechanism by which we redirect taxpayer money to out-of-town companies to relocate low-paying jobs. This is not development in any sense but a short-term political strategy that redistributes scarce community resources to those who need it the least. Revitalizing the nation’s urban centers and small town Main Streets is a strategy that can do much more to create strong, sustainable local economies at a fraction of the cost, while retaining and fostering local resources.

When I began my career in the engineering/construction industry 37 years ago, erosion from construction sites was never a stated concern. None of the huge water treatment plants and wastewater treatment plants I designed had any provisions for preventing erosion or controlling sediment. The streams, lakes, and rivers downstream from my sites no doubt did a lot of natural “settling” and maybe “filtration.”

A trip to Design Columbus 2012 in Columbus, Ohio, showcases the positive impact made by local chapters of the U.S. Green Building Council.

The USGBC’s Greenbuild International Conference & Expo is the world’s largest conference and exhibition devoted to green building. By attending you can take in three days of seminars and other educational events, see thousands of products, and enjoy live streaming and archived conference videos. Although Greenbuild is the USGBC’s premier event, local USGBC chapters host a number of similar events each year, and some are bound to take place practically in your own backyard.

If you're unfamiliar with the title of this article, or this important subject matter, don't feel bad – you're not alone. Confusion and a lack of awareness is the rule, rather than the exception, when it comes to the federal Environmental Protection Agency's (EPA’s) new Renovation, Repair, and Painting (RRP) rule, which totally redefines the way much of home remodeling is conducted. It centers on the control of dust from lead paint created from during RRP, not the elimination of the lead itself. The RRP rule is monumental – in its complexity, in the nature of the changes, and in the cost involved in compliance. Here's the EPA's explanation in a nutshell: “Under the rule, beginning April 22, 2010, contractors performing renovation, repair, and painting projects that disturb lead-based paint in homes, child care facilities, and schools built before 1978 must be certified and must follow specific work practices to prevent lead contamination.”

Welcome to the On Site channel’s Construction Administration Column. When a construction observer gives instructions directly to a subcontractor, it can lead to contentious claims. David A. Todd, P.E., CPESC, discusses how to address the issue.
