A series of severe storms in October 2016 activated or worsened numerous water leaks in state-owned buildings.
The Department of Enterprise Services is responsible for the stewardship, preservation, operation and maintenance of the state Capitol Campus in Olympia. It is a top department top priority to investigate and fix water leaks to prevent water damage to the structure, finishings or contents of the buildings.
About 20 leak sites have been identified in five historic Capitol Campus buildings – the John A. Cherberg, Insurance, Legislative, Irving R. Newhouse and John L. O’Brien buildings. Some buildings have more than one leak site.
Another 20 leak sites are spread among state-owned facilities in Kelso, Sedro-Woolley, Tacoma, Tumwater and Yakima.
In late 2016 and early 2017, Enterprise Services remedied the most severe and high priority Capitol Campus leaks:
By June 30, 2017, the department plans:
As buildings on the Capitol Campus age, their maintenance requirements increase – including the need to address potential water leaks.
A building’s exterior shell – the roof, windows, insulation, and exterior walls and doors – is designed to keep the structure water-tight and maintain a comfortable temperature for people working or visiting the facility.
For historic buildings, this building envelope can be extremely complex. On the Capitol Campus, our historic buildings have numerous architectural features that interconnect with each other. Issues with leaks are often due to breaches that occur where different types of building materials overlap.
Roofing and other building envelope elements have an effective lifespan. Once exceeded, Enterprise Services must either replace major portions of a building’s system or make temporary repairs.
Cherberg Building: An emergency repair with a construction cost of $60,000 was conducted to fix a water leak that resulted in moderately-high volumes of water entering the basement of the historic Cherberg Building, where members of the Washington State Senate and their staff work. Enterprise Services found that the leak was the result of a collapsed underground roof drain leader backing up into the building as well as an aging concrete basement wall. In the course of the repair it became evident that the soils around the Cherberg building have very poor drainage. Ultimately, the building will need more extensive repairs to correct drainage issues near its basement walls.
Enterprise Services is working to scope and gain estimates for repairs to additional leaks at the Cherberg Building.
Legislative Building: Enterprise Services believes it has found and repaired the source of the most critical leaks in the Legislative Building – the capitol building for the state of Washington. The investigation, diagnosis and repair for one location in the south west corner of the building was fairly complex and included electronic field vector mapping to identify possible breaches in the roof membrane that allow water through as well as partial flood testing of the roof membrane and drains. Ultimately it was determined that there were multiple leak locations in the building’s parapet walls and caps. The construction cost for these repairs was $34,000.
The department also installed a new metal roof above the State Reception Room where there was an active leak as part of the West Campus Exteriors project. Until this year, the only cover over this portion of the building was exposed sandstone. The new roof was bid as part of a larger West Campus Exteriors project, with a $54,000 construction cost for the roof portion of the project.
The department is investigating the cause of other intermittent leaks in the building that became active in 2016, and is working with consultants to scope repairs and gain cost estimates for the repairing the new leaks.
Insurance Building: Enterprise Services fixed a leak originating in the roof by repairing failed junctions between the roof’s membrane and an aging metal roof systems as well as a roof drain. The temporary repair cost $10,000. Without a full roof replacement, more temporary repairs will be needed. Work is dependent on funding.
John L. O’Brien Building: Enterprise Services has hired a consultant to investigate and design repairs to fix leaks in this building, where members of the Washington State House of Representatives and their staff work. Long-term repair costs are dependent on the complexity of the scope of work.
Temple of Justice Building: Work included in the West Campus Exterior Buildings Project that started in February 2017 is focused on maintenance of the stone exterior on the Washington State Supreme Court building.
Irving R. Newhouse Building: Leaks in this building appear to be related to needed masonry repairs. Enterprise Services is working to scope and gain repair estimates.
Natural Resources Building: A new $3.2 million roof was installed on the Natural Resources Building in 2012.
Department of Transportation Building: One of several recommended roof repairs was completed in 2015, at a construction cost of $45,000.
Employment Services Building: A new roof costing $50,000 was installed as part of a $300,000 elevator repair project that was completed in 2015.
The construction costs described above reflect only the amount Enterprise Services paid to a contractor for their scope of work for each project. For most projects, construction costs represent only about 60 to 70 percent of the total costs – and don’t include associated expenditures such as:
Leak repairs are prioritized based on a number of factors:
