Special Project RECM1-98, Repair/Renovate Office Spaces, Buildings 251 and 252, Makalapa, Pearl Harbor, Island of Oahu, Hawaii

  • Client: Department of the Navy
  • Contract Amount: $11,220,000

This high visibility project consisted of all design and construction necessary to repair and renovate the deteriorated conditions of the administrative facilities for the Commander-in-Chief of the US Pacific Fleet located in historic Buildings 251 and 252. One of the major undertakings of the project included soil modifications via compaction grouting to correct excessive ground settlement. This was performed following the complete demolition of the ground floor except for the structural posts, stabilizing the building with temporary bracing, and removing the chlordane-contaminated soil under the building to allow access for the equipment. Other features of the project included various structural upgrades to meet current seismic and wind requirements, along with completely new interior and exterior finishes that met both the current needs of the facility and the historical preservation requirements.

The success of this project resulted in a Historic Preservation Honor Award presented by the Historic Hawai’i Foundation.
