What types of testing occur within a construction and engineering laboratory?

The safety, quality, and suitability of construction materials for a given construction task is paramount, and this is better ensured with lab testing. Not only are fasteners, lumber, and adhesives tested, but also the underlying soil and rock of a construction site. A wide range of materials (e.g., wood, iron, concrete, shingles) are tested using standardized test methods, measuring properties such as tensile strength, water penetration, and impact resistance.
