Construction Site Testing Is Key To Ensuring Full Safety

Before any building can be erected, the builders must determine that conditions and materials will remain stable over the long term. A failure to determine these conditions prior to the beginning of construction will almost certainly have lethal consequences in a structural collapse. For this reason, construction testing services are an absolutely essential element of any building project to ensure that construction can proceed safely.

Determining that the ground is good and solid is the vital first step before construction can begin. Testing of the building site looks to establish the following conditions: quality of the soil, solidity of underlying rock layers, susceptibility to dynamic conditions such as erosion and seismic events, and presence of possible subsurface voids. These factors are determined by a number of tests, including the taking of drilled core samples and the use of electrodes to make electrical soundings of the site.

Other characteristics subject to evaluation include determining the capacity of the ground at the building site to pass an electrical current. This factor is vital to determine the number and placement of electrical earthing systems for towers or any special structure that has unique grounding requirements. These are vital to protect sensitive electrical equipment and circuitry to be housed in the completed structure. Seismic refraction analysis determines the depth to a bedrock layer and the properties of the rock at that layer. This is done by generating seismic waves by either a method as simple as a hammer striking a metal plate or as complicated as an explosive charge. Transducers read the return pulses and from these engineers can have a fairly accurate reading of the soil and rock densities at various depths.


Other testing services evaluate the quality of concrete, masonry, grout and mortar materials through the use of heavy duty compression machines capable of subjecting samples up to the equivalent pressures generated at 400,000 lbs. of rest mass. These tests determine compressive strengths of the various materials, flexure strength of concrete, the effect of impurities and overall soundness and water retention and absorption properties. Asphalt is subjected to quality control tests to determine moisture sensitivity, compaction, stability at various conditions. And the tests can be conducted in laboratory facilities or from mobile labs that can be driven out to the construction site. The engineers at acs testing will perform any evaluation required to guarantee the quality of both the ground and the materials used for the project.
