Colonial Grand Pacific Condominiums (CGP) was formerly known as two separate buildings, Grand Pacific Hotel built in 1889 and the Colonial Hotel built in 1901 and located at 1119 First Avenue in downtown Seattle. The two building were renovated and joined in 1981 that consist of 37 condominiums units. The building facade is constructed with unreinforced brick and stone masonry, steel juliette balconies, wood casement windows and a multi-layer hot applied roof.
Colonial Grand has multiple projects that need to be performed over the years. There first project was a re-roofing project that Tatley-Grund was awarded through a bid process and performed the work on a Guaranteed Maximum Price (Gmax) contract.
Owner: Colonial Grand Pacific HOA
Contract Value: $1.6M
The scope of work was to perform a full roofing replacement and install a new SBS 2-layer Alsan Soprema roofing system. At the same time, TGI was to perform structural enhancements to the original framing structure, install new skylights (27 in total), new windows, doors and pavers at the recessed unit deck (8 total) and integrate a fall arrests system that is to be integrated structurally. In addition, the work needed to be performed during ideal weather conditions in order to avoid impact from rainfall in a roofing project of occupied spaces. During the course of the project, a change order was approved to subdivide and install new walls and windows at four attic spaces that were to be converted at a later date to living space.
The Colonial Grand Pacific roofing project was an overall success as it was performed on schedule with minimal impact to owners and on budget. The design and integration of the fall arrest system was a massive challenge and required out of the box thinking to proceed with roofing installation while manufacturing and design was still being completed. At the end of the project, TGI was able to seamlessly install the fall arrest structure, which is mostly beneath the roofing, and provide water tight finish integration within the roofing system. The installation of the fall arrest system has improved safety for the building and future projects at location.
An additional unique aspect of the job was job-site security. Due to the location of the building, TGI needed to enhance the scaffolding security to minimize the ability for trespassing into the construction zone. During the project, CGP was approached by a professional film company and asked to utilize the stairway and scaffolding as part of the film. This was approved and required for TGI to remove of security measures for a small amount of time.> Back to Multi-Family
