Evaluation of how products and systems perform in real life applications

Advanced Framing: An Examination of its Practical Use in Residential Construction The case study highlights the advantages of and barriers to widespread adoption of OVE practices.
Corrosion of Metal Connections in Preservative-Treated Wood Structures Recent testing of alternatives to CCA (chromated copper arsenate) indicates that some of these new wood preservatives can be more corrosive to metal connectors and fasteners than CCA.
Implementing a Quality Assurance System: A Trade Contractor Case Study A quality assurance system requires trade contractors to accept responsibility for their own quality assurance without builder intervention.
Quality Assurance System for Wood Framing Contractors This document is geared toward the framing activities of home building. It identifies a framework that a contractor can use to develop a quality management program that delivers maximum value.
TechPractices: Long and Gordon, Dove Street, Boston, MA In an area noted for its crime, a builder teamed up with the City of Boston to tear down a crack house and replace it with durable, energy efficient, two-story homes, strategically placed to tie together and revitalize the neighborhood.
The Performance of Perforated Shear Walls with Narrow Wall Segments, Reduced Base Restraint, and Alternative Framing Methods This report is part of an effort to develop, confirm, and enhance exterior shear wall design. The ultimate goal is to provide both safety and economy to housing construction in all wind and seismic areas in the United States.

Questions & Answers [Back to Top]

Frequently asked questions, answered by home building professionals

Can 2x8 floor joists spaced at 16 inches span 16 feet?
Can I-joists be notched?
Can you tell me about the new treated lumber for outdoor structural use and ground contact?
How do I know if the structure of a one-story home is adequate to support an additional story?
I am building a garage with an 18-foot garage door. Will three, 2x10s nailed together for 4 1/2" thickness be sufficient for this span if I stagger the seam by at least two feet?
I want to build a home with a loft with a 12/12 pitch roof on it, but am unsure of the roof-ceiling detail. It is about 30 ft. wide by 60 ft. long with 12-ft. 2x6 stud walls. I also want to maximize the headroom upstairs and put a flat ceiling across the entire length of the room. What material do I need to use for the rafters?
I would like some information on building with plywood box beams. Are they accepted by the building code? What is the load-bearing capability of box beams?
We are remodeling a house with two 4x4 posts that extend through the deck to the roof. We are planning to remove the deck and need someone who can analyze the trusses to determine if the posts are required to hold the roof or only the deck. Do you have any contact information for someone who can help me do this?
We are working on a dining room and living room that are next to each other and have eight-foot ceilings, and I would like to create cathedral ceilings for both rooms. Installing sheetrock directly to the roof rafters looks like the easiest plan. The ceiling will be flat below the scissor beams which frame out the peak of the roof. If I install all the electric, insulation, sheetrock, etc. could I just cut out the existing ceiling and studs without doing any structural damage, do I have to shore up the roof before the ceiling is removed?
What fasteners can be used with preservative-treated lumber?
What is an acceptable range for moisture content of framing lumber?
What is the maximum hole that can be drilled in 2x4 studs in load bearing walls for wiring or plumbing?
What is the minimum thickness of OSB for roof sheathing?
What is the purpose of lateral wall bracing and what is the minimum width of braced wall panels?
What is the typical span for a wood roof truss?
What should I do about mold spots on lumber while building a home?
When do I need to provide in-line framing?
