As geotechnical consultant, we performed a subsurface exploration program and made recommendations for foundation and earthwork. During construction, our field engineers provided on-site observation of unsuitable fill removal, and foundation subgrade preparation and compaction.
Early geotechnical samples were analyzed for environmental parameters. We designed and performed surface and subsurface sampling for environmental constituents to characterize surplus construction soils. Soil management plans were developed to provide guidance to the general and excavation contractors. We explored cost-saving alternatives for surplus soil disposal and monitored air quality for protection of workers and the surrounding community.
The Solutions Unearthed
- We provided preliminary and final geotechnical reports including recommendations for foundation design, construction, and minimization of excavation for the foundations to avoid environmental contingencies.
- We developed alternate foundation design utilizing rammed-aggregate piers and micro-piles in areas of unsuitable fill in order to minimize excavation and disposal costs.
- Several phases of environmental investigation were performed including beneath existing building floors and during building demolition in order to preserve the tight construction schedule.
- Soil management plans were developed to control soil movement and minimize the cost for offsite surplus soil disposal.
- Ambient air was monitored for particulate concentrations and sampled for chemical constituents. Results were communicated to the local health department.
- Our geotechnical and environmental staff worked in close conjunction with the owner, architect, construction managers and contractors to address unforeseen conditions and reduce costly construction delays.
