Stamping press pit and press foundations at NASG Tennessee 2 - Corporate HQ
Modifications and additions are routine for Brindley Construction, but the size and location of the excavation required for the addition of the press pit and foundations posed several challenges.
First, the excavation site was inside an existing building. While this alone was not an issue, the finished size of the proposed pit was 550 feet long, 50 feet wide and 35 feet deep – a massive undertaking. Care had to be taken to prevent damage to the existing building’s foundation while digging, setting up forms and pouring new concrete walls for the press pit and foundations.
The finished pit provided foundations for 13 stamping presses ranging in size from 250 to 1,500 tons, with provisions for the installation of a fully-automated scrap removal system. Above the pit, the project included the installation of two bridge crane systems to transport material throughout the facility.
