Welcome to the On Site channel’s Construction Administration Column. Who should pay when work is done out of contract? Here David A. Todd, P.E., CPESC, gives his opinion.

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 and administration of the construction contract. The focus will be on the customary duties of the owner, contractor, and design professional as typically described in the contract documents.

Contractor to Contractor: Follow professional interior contractor Robert Thimmes as he demonstrates how to frame-out openings. This third installment in a series of articles, Framing Walls With Light Gauge Metal Studs, visits the common practices for the framing of window and door openings.

When plumbing your openings and transferring your layout to the top track, turn your stud 90 degrees and attach your level high on the stud flange. Align the bottom edge of your stud with the edge of your opening, get the bubble "dead-on" and mark the top. Attaching your level to the flange rather than the webbing gives you a straighter surface that is less prone to bow, thus reducing variables and improving quality. Since one side of your opening has been plumbed, now just measure over the actual width of the opening and mark to establish the top of the other side.

You’ve been reading about BIM. It’s being used by all of the big companies, and they’re talking about the benefits they’ve reaped.You know that BIM will be coming to your workplace soon, too, but how and from what direction? Are you just supposed to buy a software suite and hope for the best?

As it turns out, that’s an approach not even the product makers and suppliers would recommend. Building information modeling (BIM) is increasingly being described as a "disruptive" technology, even by its biggest promoters, for a reason.“Most people now understand that BIM is a process, not a product,” says Catherine Palmer, Sr. Industry Marketing Manager, AEC Solutions at Autodesk. “It’s a paradigm shift.” When asked how small to medium sized firms should handle the move to BIM, Jim Lynch, Vice President, Building Product Line Group at Autodesk recommends education as a first step. “Position yourself by beginning with the concept,” says Lynch, “Then embrace it.”

Contractor to Contractor: Follow professional Interior Contractor Robert Thimmes as he demonstrates how to stand up and brace off walls. This second in a series of articles, Framing Walls With Light Gauge Metal Studs, starts with your walls located, lines chalked and bottom track already shot down (for details on this process, see Metal Stud Track Layout and Shoot-Down).

In the previous installment of “Contractor to Contractor,” we reviewed the details of how to perform the track layout and shoot-down for metal stud walls. Now we move on to the second part of our discussion: standing up and bracing.

Green building practices have come on the scene so fast that many implications – and unintended consequences – are just now coming to light. How can you protect yourself, legally speaking, in these new situations?

Environmentally conscious building practices are typically associated with positive outcomes, such as improved energy efficiency, reduced material waste, financial savings as a result of tax incentives, and improved builder reputation. In addition to these benefits, research indicates that certified green buildings cost less to operate; command higher occupancy rates; contribute to a healthier, safer environment; and can possibly enhance employee recruitment and productivity.

Contractor to Contractor: Follow professional Interior Contractor Robert Thimmes as he produces a layout and final shoot-down of a metal stud track system.

Plumb, level, square, and straight: all carpentry is the same, right? Well, no. Basic building principles apply, but how you build with metal studs differs greatly from building with wood. The following discussion offers a systematic explanation of installing metal studs, with various best practices for each step.

What makes for success as an interior contractor and what are the basics of staying in business? An experienced contractor takes a look at some of the misconceptions that plague the industry and brings the focus back to fundamentals that can help you understand the full value of your skill set.

Being in business in this economy means understanding the fundamentals of our industry and where it's going. As a small business owner I've seen my fair share of ups and downs. Usually most of the misunderstandings and problems can be solved by a little inquiry and a lot of listening.

From green building to Building Information Modeling (BIM), new technologies are changing the construction game and changing it fast. What legal and contractual protections can be put in place as the workplace adopts these technologies?

There’s no question that, in the design and construction industries, Building Information Modeling (BIM) is what’s termed a “disruptive technology.” Since the 1980s, when PCs finally became affordable enough for architectural practices to begin to bring them to bear on design, computing power has become ubiquitous and increasingly influential on budgeting, programming, design, and construction.

The new Barclays Center will not only provide a home for the Brooklyn Nets but will offer the surrounding community a civic space and an architectural  icon.

Not since 1957, when the Dodgers left Brooklyn for Los Angeles, has this popular New York borough been so close to finally having a major league sports team to call its own. Despite significant public opposition, a faltering national economy, a Supreme Court case over eminent domain, and a Frank Gehry design deemed too expensive, the Barclays Center is well underway, with construction due to be completed in September 2012. Designed by SHoP Architects and the sport facility practice at Ellerbe Becket, this voluptuous mass with weathered steel skin will be the $4.9 billion home of the Brooklyn Nets NBA team.
