In April 2015 Sierra successfully completed construction of a build-to-suit concrete tilt-up addition to a pre-existing structure for Panattoni Development in the industrial area of South Seattle. The concrete tilt-up addition is 111,000 square feet and includes a 22,000sf mezzanine and a 43,000sf office space and light manufacturing tenant improvement. Modifications were made after addition was leased to tenant DCG ONE for use as printing facility in the new construction, as well as Cleanscapes which took over the existing structure.
The Cleanscapes tenant improvement took place in the existing building on the Skyline Distribution Center project. Originally built as a distribution center, the structure required modifications to accommodate Cleanscapes waste management business. Existing mechanical, electrical, and plumbing had to be tied-in to the new systems. Three interior columns were removed and replaced with large beams to accommodate the desired maneuvering space. Three 24’ x 30’ coiling doors were also added and required structural modifications to the building. The building also had existing exhaust fans, however they had to be expanded to accommodate waste management requirements. A lunchroom and additional bathrooms were added to accommodate more employees. Communication required working with client selected subcontractors and the project owner’s vendors to complete the project.
