Marchese Construction

Due to the poor quality of the soil, the construction of a project in Pooler, Georgia can be challenging.  Many of the good sites have buildings on them already.  What are left are areas that once were economically unfeasible to build upon.  As the cost of the raw land has increased these site have become profitable for developers.  First we must remediate the site.  In most cases this take the form of imported class “A” structural fill.  After the topsoil is removed, two feet of structural fill is brought in and placed on the site.  One of the keys to a  quality job is in the compaction.  The new material must be placed and compacted to six inch lifts.  After placement and compaction the soils are tested to ensure that they achieve acceptable bearing ratios.  The standard test is the Proctor Test. In the lab the Modified Proctor (ASTM D1557) uses a 10 lbs hammer that drops 18 inches while the Standard Proctor (ASTM D-698) uses a 5.5 lbs hammer that drops 12 inches.  As a general rule 95% of Modified Proctor under buildings and roads and 98% under structures.   Your utilization of a quality Geotechnical Engineering firm is critical to the success of your project.  From the profile of the incoming fill to the compaction testing of the finished site they must be continually involved.  As a general contractor, Marchese construction is deeply concerned about the quality of the imported fill.  We know the good local pits and we constantly monitor the consistency and the water content of the incoming fill.  A strong building pad is crucial to the structural integrity of the structure.
