Scope of Services:

1) Same-day response to fire damage in order to assess the extent of necessary repairs

3) Detailed progress reports to help the client make plans regarding time-sensitive re-opening of storefronts, roads, parking spaces, and sidewalks
A transformer fire at Market Common Clarendon in Arlington, Virginia had caused damage to the interior of an underground electrical vault that provided power to the surrounding retail property. Mosaic was able to be on-site within hours of the fire in order to coordinate with the client, establish its needs, and develop a scope of service to assess damage. Mosaic was retained by Regency Centers to perform the following tasks:
1)Assess the existing fire damage and design details for necessary repairs
2)Develop a shoring plan to allow access to time-sensitive electrical repairs
3)Conduct quality assurance for critical construction milestones
Mosaic’s role included making site visits to assess the construction progress, performing quality assurance on repairs made, and providing design consultation throughout the duration of the work.
Detailed evaluations were made to map damaged areas so locations of repairs could be isolated, limiting the extent of the structure that needed to be included in the repair contract.
The project involved partial depth repairs of the underside of the concrete slab and the vault walls, as well as replacing compromised structural steel. Waterproofing components were also replaced to protect the vault structure and the internal electrical equipment for long-term service.
