Find a material testing lab that can deal with all types of materials

Some material testing services deal only with soil or cement issues, but this often overlooks some of the more important areas on a construction site. Look for a company that can test soil, concrete, steel, masonry, fireproofing, pavement and foundations.

I recommend: Go with a testing company that can handle as much as you do. MACTEC can test more than 10 different types of building materials, and Gallet can handle a similar workload.

Choose a construction materials testing firm that will stay with you throughout the project

A good company will help you test your materials pre-construction, work with you throughout the project and then perform audits after the work is completed. Be wary of any contractor that comes out and does a one-time test and then doesn't follow through after the fact. Hiring a full-service testing firm will save you time and costly repairs, should problems arise along the way.

I recommend: Do business with a full-service firm. ATC Associates is known for its customer service and high standards. This company works with you from day one to ensure that your project is up to code every step of the way. Carlson Environmental also can work with you on every phase of your project.

Get quotes from several vendors for building materials testing

Most companies won't give you a price quote until they come out and evaluate the job site and the task at hand. Expect to spend a bit of time at the beginning gathering quotes and comparing services from several different firms. You should get the quote in writing so that you can use it when bargaining with other firms.

I recommend: Shop around for the best price. You can start by contacting Desman Associates, Advance Testing, WDP and TERRADON to get quotes for your specific construction project. Compare them to find the best value for your money.
