Objective:
 PHC-REC was contracted by the Wyoming Department of Environmental Quality, Abandoned Mine Lands Division (AML) to initiate work related to AML Project 17F-7, the Kirwin Stabilization Project. The project involves the stabilization and preservation of numerous buildings, including two mineshaft houses and the Superintendent's House located in the historic ghost town of Kirwin.
 The Tumlum Mine shaft house was constructed approximately 110 years ago and is one of the most unique structures in the Kirwin Mining District. The historic Wolf Mine shaft house, was developed fifty years later in the 1940's. Having these preserved shaft houses from different eras makes Kirwin an ideal site to interpret the evolution of mining.

PHC Solutions: 
 PHC-REC completed eligibility research and determination, costing, and preparation of contract documents, specifications and plans for the stabilization of the Mine Superintendent's House. Preparation of the plans and specifications required close and continued coordination with the SNF, USDA Forest Service, SHPO, and AML. Specifications were prepared based on the Secretary of the Interior's Standards and Guidelines for the rehabilitation, restoration, preservation and reconstruction of historic structures. The final design details specified how to stabilize the structure including adding material to support the existing foundation, removing and replacing sill and top logs, stabilizing dormers, replacing deteriorated ceiling joists, resheathing the roof, preserving historic building members and establishment of surface drainage away from the structure.
