Capitol Campus Construction Project

Old Capitol Building Exterior Repairs

View information about this project.

Legislative Building Exterior Repairs (phase 3)

Overview

This project will complete the sandstone preservation, cleaning and exterior leak repairs begun in the 2009-11 biennium.

In this phase of work the contractor — Western Waterproofing Co. of Renton — will repair and repoint mortar joints around the four mini-domes and other areas below the main dome.

The contractor will repair or replace drain assemblies on the exterior plaza near the north stairs.

In addition, the contractor will clean portions of the building exterior. Due to budget limitations, there may be some sections of the building that are not addressed during this project.

The work is needed because water has been leaking into the building through deteriorated stone, mortar, sealants and aging roofing systems, causing expensive structural and interior damage to the building.

Leaks through deteriorated stone, mortar, sealants and aging roofing systems damage the substructure and interior finishes.

Cleaning, sealing, re-pointing, and roof maintenance will prevent further damage caused by leaks, minimize the growth of damaging moss and lichens and extend the life of the building.

When does the project start and end?

Work began in August 2014. Completion is expected by February 2015, but is weather dependent.

What are the impacts?

There will be some partial temporary closures of the entrances and exterior walkways during the project. The work will be noisy at times because grinders will be used to remove mortar.

East Plaza Stair Tower Replacement and Waterproof Retrofit Project

Overview

Water has been infiltrating the Plaza Garage, undermining and weakening the structure, corroding essential components and creating a growing risk to life and property. Structural deterioration is escalating at the western entrances of the parking garage, where structural beams and concrete walls and ceiling panels are loosening.

This project will repair the structural integrity of the concrete beams and panels at the western garage entrances off of Capitol Way, along with reconstruction of stair towers 1 and 8 due to rotted steel beams, rusted panels, and the spalling concrete walls.

This project will re-build elevator 1 to prevent water infiltration damage to the electrical and mechanical systems.

When does the project start and end?

Construction began September 2014. Substantial completion is expected by June 2015.

What are the impacts?

Stair towers 1 and 8 are closed. Employees who park in the garage should use stair towers 2 or 7. View a map of the garage.

Critical Campus Steam System Repairs and Governor’s Mansion Boiler Replacement Project

Overview

These interrelated projects will repair and update decades-old systems, improve safety and boost energy efficiency. The department is using its Energy Savings Performance Contracting program for the projects. The program allows the use of utility savings to help offset project costs.

The projects will:

  • Replace the campus powerhouse chillers (cooling system).
  • Repair the campus steam system (heating system).
  • Replace the heating system for the Governor’s Mansion. - Complete

The current steam loop serves 13 office buildings and the Governor’s Mansion. Removing the mansion from the steam loop will optimize energy savings on the Capitol Campus by allowing operators to turn the heating system down or off when office buildings are not occupied, including overnight, on weekends and holidays when the office buildings are unoccupied. This makes more efficient use of the campus systems’ capabilities.

The boiler replacement project will make it possible to remove the Governor’s Mansion from the central system.

When does the project start and end?

Mansion work began July 2014 and was completed November 2014. The rest of the project is scheduled to begin in December 2014 with anticipated completion in March 2015.

What are the impacts?

Replacement of the campus powerhouse chillers could require weekend air conditioning outages.
