San Francisco 49ers Levi's Stadium
SANDIS provided construction staking, utility locating, and 3D laser scanning services for the first professional football stadium built in California in multiple decades. A precision control network was established by SANDIS utilizing high accuracy survey equipment and proprietary survey control protocol for control networks. SANDIS’ protocol uses a combination of industry and state standards for first order control networks. Our internal control verification process maintains project accuracy for the life of the project. Control was field set with monumentation place in concrete bases to minimize potential for site disturbance.
Utilizing our established site control network, SANDIS is providing building control for all trades on a floor by floor basis. The building control is located using one second Total Stations, operated by survey crews with experience in maintaining and transferring precision building control with a tight tolerance. The process involves factoring into our survey the effect of atmospheric conditions, the expansion and contraction of steel and concrete, building settlement, and other site specific challenges.
