The project was the expansion of an existing parking lot to a high capacity parking garage located at very busy, high-end shopping mall. The construction challenges associated with the expansion included both geotechnical aspects of the subsurface, and impacts to [ Read More… ]
The Creek Protection Project consisted of several phases of work including increasing the hydraulic capacity of the creek. Coastal installed permanent rock anchors within a post and panel floodwall positioned in the creek. In order to resist the design load, [ Read More… ]
The project required drilling two 8” diameter holes for the installation of new waterstops between the selected monolith joints within the dam structure. The holes were required to precisely follow the vertical joints between the monoliths and to deviate no [ Read More… ]
Limited mobility grout is injected into void spaces within soil or rock, soft soils, or the soil-filled cavities of the bedrock, to improve the subsurface soil and rock conditions by filling the void spaces and replacing soft, loose soils with [ Read More… ]
This project called for a wall stabilization which consisted of the installation of 93, 30-foot solid bar nails into various underlying geotechnical conditions. Also, a two inch construction layer and a six inch final face of shotcrete was applied to [ Read More… ]
