Seattle City Hall Plaza Restoration Predesign Findings The findings of the latest investigation generally confirm the construction assemblies indicated in the record as-built documents, and general conclusions are as follows: -The leaking appears to be caused primarily due to the lack of a continuous waterproofing membrane system and flashing as designed in the original construction drawings. -The waterproofing system consists of water-repellent ad-mixture (Caltite) has proven to be an ineffective water resistive barrier. -Deficiencies in the existing under slab drainage assembly, and detailing of subsequent repair attempts, appear to further contribute to the water infiltration issues.

Seattle City Hall Plaza Restoration Scope of Services In order to completely address the water infiltration issues, it is the recommendation of the “Plaza Water Infiltration Investigation Report” dated March 29, 2019, that a properly detailed waterproof membrane assembly be installed throughout the plaza, planters, and fountain. Scope to accomplish this will require, at a minimum, the following: -Removal of all concrete paving, stone pavers, and landscaping, and underlying materials, down to the structural concrete slab, throughout the plaza, planters, central stair, and fountain. -Removal of stone wall veneer at the building a minimum 12” above topping slab elevation to tie waterproofing into existing wall weather barrier system. -Installation of a membrane waterproofing system with flashing and drain mat throughout. -Installation of a fully soldered stainless-steel pan along the length of the exterior fountain. -Modification of drains to reduce the accumulation of water at the structural slab. -Reinstallation or replacement of hardscapes, stone veneer, and landscaping to match existing.
