Contracted scope of work included test piling at locations around the site to determine ground conditions (the client’s designer provided the permanent state requirements for each pile). Black Construction modified the pile design to accommodate the stresses of transportation, handling and pile driving as well as early concrete strength for quick mold release; compression load test on various individual piles using 1000t of weight on a reaction frame; manufacturing octagonal prestressed concrete piles of varying length and strength capacities at Black’s twin 400-foot casting bed in Barrigada, Guam; design and manufacture of pile male/female structural connections to provide an increased effective pile length; transportation and handling of the piles, up to 65 feet long, to site in coordination with the rate of pile install operation; coordination of the pile installation with the client, their designers and other contractors on site; driving 1,300 precast piles to refusal or to depth limitation (total length of piles, over 12 miles); return to previously piled areas to install additional piles as the updated design dictated; adapt methodology and resources as the foundation design evolved; comply with noise and environmental criteria in this sensitive tourist location; seven day per week piling for eight months to mitigate the delay to the overall hotel construction schedule by the increased pile numbers; and preventative maintenance and support operations to keep the piling equipment operational during daylight hours.
