WHAT ACCO DELIVERED
ACCO played a design-build role in working with HNTB, project architect, and Turner/Devcon JV, the general contractor, to continuously provide enhancements to the project during the pre-construction phase.
ACCO’s BIM Detailing team worked closely with TD JV and the architect to fit the mechanical systems into the unconventional structure. The entire BIM coordination process was very challenging due to the size and complexity of the project, and ACCO detailers proved vital to the process through their expertise in solving design conflicts and issues that arose during coordination.
ACCO was instrumental in playing offensive coordinator to TD JV with the development of a sequencing plan for logistics, stocking and installation. The stadium was built as four independent projects running concurrently, with the construction team working together to meet the scheduled completion with no delay-of-game penalties. Due to the tight schedule, logistics were the key challenge of the job. As identified in an article from the Mercury News there was virtually no storage space on the job site, leaving the team to rely on pull scheduling, prefabrication, and just-in-time delivery for all sheet metal installations.
ACCO suited up 55-70 field sheet metal craftspeople and was able to meet or beat aggressive schedule milestones – in most cases coming in before the two-minute warning.
The work performed also earned ACCO a safety award from the GC team.
