	~~===Construction materials and geotechnical testing: The basics===~~
	Like any other manufactured materials, construction materials such as fasteners, lumber, and adhesives have a certain level of expectation attached to them, that they will be safe to use, of good quality, and will perform in the way advertised by the manufacturer. And just as in other industries, laboratory testing of these construction materials is an important component of giving consumers more confidence in what they are acquiring and using. Can a bolt used in a bridge sufficiently resist corrosion and maintain sufficient shear strength to fulfill its purpose? Can a 2x8 piece of lumber meet specific strength and density requirements to ensure it can effectively act as header material? Does the pull-off strength claimed by a manufacturer for its construction adhesive actually meet that claim in multiple environments? These and other questions are asked about the physical, chemical, and mechanical properties of construction materials to ensure they are fit for purpose.

	But when it comes to construction and engineering, it's more than simply construction materials that need to be tested; the area where the structure itself is going to end up also has characteristics that must be examined. This geotechnical testing (or geotechnical investigation) examines soil and rock for load-bearing and seismic (i.e., engineering) properties to ensure any proposed structure can safely endure in that location for a minimum set of time.<ref name="PatelGeo19">{{Citation \|last=Patel \|first=Anjan \|date=2019 \|title=Geotechnical investigation \|url=https://linkinghub.elsevier.com/retrieve/pii/B9780128170489000093 \|work=Geotechnical Investigations and Improvement of Ground Conditions \|language=en \|publisher=Elsevier \|pages=87–155 \|doi=10.1016/b978-0-12-817048-9.00009-3 \|isbn=978-0-12-817048-9 \|accessdate=21 November 2023}}</ref> Geotechnical engineers examine soil and rock mechanics, soil-structure interactions, geomechanics, ground improvement strategies, and various stabilities, as well as characterize geomaterials with laboratory and ''in situ'' sampling and analysis.<ref name="UoDGeotech22">{{cite web \|url=https://ce.udel.edu/research/research-overview/geotechnical/ \|title=Geotechnical \|publisher=University of Delaware \|date=2022 \|accessdate=21 November 2023}}</ref> What are the compaction characteristics of the soil and splitting tensile strength of the rock where a bridge is to be constructed?

What does a consolidation test say about the preparatory work that must be done on a site before a concrete pad for an office tower can be poured? These and other questions drive geotechnical testing and its various physical, chemical, and mechanical tests.

	When we examine the construction materials and geotechnical testing laboratories accredited by the American Association of State Highway and Transportation Officials (AASHTO), ANSI National Accreditation Board (ANAB), American Association for Laboratory Accreditation (A2LA), and the International Accreditation Service (IAS), we find a vast array of standardized test methods to which labs are accredited to by extension of their [[ISO/IEC 17025]] compliance. The next section examines these accredited laboratories for major clues as to what types of testing occur within those labs.

	~~===Types of testing===~~
	When examining the scope of accreditation of these types of labs to AASHTO, ANAB, A2LA, and IAS requirements, trends emerge on not only what raw materials are getting tested (e.g., soil, wood, iron) but also what other prepared construction materials are getting tested (e.g., asphalt, concrete, roofing shingles).

			When we examine the construction materials and geotechnical testing laboratories accredited by the American Association of State Highway and Transportation Officials (AASHTO), ANSI National Accreditation Board (ANAB), American Association for Laboratory Accreditation (A2LA), and the International Accreditation Service (IAS), we find a vast array of standardized test methods to which labs are accredited to by extension of their [[ISO/IEC 17025]] compliance. The next section examines these accredited laboratories for major clues as to what types of testing occur within those labs.

	Like any other manufactured materials, construction materials such as fasteners, lumber, and adhesives have a certain level of expectation attached to them, that they will be safe to use, of good quality, and will perform in the way advertised by the manufacturer. And just as in other industries, laboratory testing of these construction materials is an important component of giving consumers more confidence in what they are acquiring and using. Can a bolt used in a bridge sufficiently resist corrosion and maintain sufficient shear strength to fulfill its purpose? Can a 2x8 piece of lumber meet specific strength and density requirements to ensure it can effectively act as header material? Does the pull-off strength claimed by a manufacturer for its construction adhesive actually meet that claim in multiple environments? These and other questions are asked about the physical, chemical, and mechanical properties of construction materials to ensure they are fit for purpose.
