Naval Facilities Engineering Command (NAVFAC) Hawaii recently completed a design-build project at Pearl Harbor Naval Shipyard/ Interm-ediate Maintenance Facility’s (PHNSY/IMF) building 155 while maintaining the structure’s historic window features.

“Prior to this window replacement project, building 155 was not only aesthetically unappealing, but it was a safety hazard due to broken glass and the inability to open the windows for ventilation,” said Jonathan Mizushima, PHNSY/IMF shop 11 branch head.

“The numerous window panes that were missing also gave birds additional ways to enter our building which posed a health concern because of the large amount of bird droppings.”

In 2011, NAVFAC Hawaii awarded a $15.8 million contract to Manson-Nan Hawaii, J.V. to renovate the building’s largest asset, its windows. The focus of the project was directed toward modernizing the building’s profile as well as addressing safety concerns due to the windows’ aging condition.

“This project was unique because we were working side-by-side with the PHNSY/IMF maintenance facility employees, who stayed clear of renovation areas so there was no disruption to their daily activities,” said Ryan Tamashiro, NAVFAC Hawaii project manager.

“Large scale upgrades, such as with building 155 involve a lot of cooperation from all in order to ensure a culture of safety is retained in a construction area.”

Until recent years, building 155 had been relatively untouched since its construction in 1941 and is classified as a category I historical structure. As a result, historical preservation stakeholders whose interest is to ensure the preservation of the building’s significant physical features were involved in this project.

Currently, building 155 provides support to PHNSY/IMF personnel and houses the shipfitting shop, welding shop and lagging shop.

Today, 1,700 new steel-framed windows encompass all four tiers of the facility on each side of the building. The new windows not only fit historic preservation requirements, but are also aesthetically pleasing and allow for greater visibility for personnel working within.

“Employees are now able to open all the windows, which make working in the building more pleasant, and the risk of falling glass has been removed,” Mizushima said. “The biggest improvement is that our building is now a better representation of the pride PHNSY/IMF’s structural shop takes in ‘Keeping Our Fleet Fit To Fight!'”
