In order for the construction industry to achieve real gains in productivity, new work habits and workflows must be adopted. Fortunately, new tools and technologies can help with this process.

Each day, the members of the team talk with one another to verify tasks for the day. Each week, the superintendent holds foreman’s meetings to gather and disseminate information to the field. Each month, the general contractor meets with the subcontractors and suppliers to verify approval and release of materials. A strong and productive project depends on this type of structure and diligent methodology.

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.

Contractor-to-Contractor: In this installment of Rob Thimmes’ series on framing walls with light gauge metal studs, he reviews the basics of hollow metal doorframe installation.

During your framing process, the question of when you should set welded hollow metal doorframes must be addressed. Many contractors prefer to install doorframes before the walls are built. This facilitates the ease of fastening the "feet" down to the floor. After the frames are fastened down, braces are required to keep wind or inadvertent contact from toppling the freestanding frames. Then, as the framers come to a pre-installed doorframe, they simply remove the braces and frame to, over, and around the assembly. Another method is to install the frames at the time the walls are built. Roughly, this method follows the same progression as the first method without the need to temporarily brace off the frame. The framers build walls until they come to a door opening; then they get down off their scaffold and set the doorframe, after which they resume framing walls. The doorframe need not be braced off when employing this method, since the doorframe is permanently attached to the studs. The drawback to this method is "switching gears": I have found that keeping crews productive and on task is easier when they don’t have to carry equipment for two separate operations and mentally bounce back and forth between them. However, the ease or advantage of either of these two methods is usually negated by late-arriving door frame deliveries (a very common problem). The last method involves setting doorframes after the walls are built. In my experience, I have found this to be the most common occurrence. It is with this last method that we will concern ourselves today.

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.

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.

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.

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.
