HPZS conducted an analysis and repair plan for the historic concrete structure Jackson Lake Lodge, designed by architect Gilbert Stanley Underwood and built in 1954. This building is the first example of mid-century modern international Style in the National Parks system. It was listed in the National Register of Historic Places as an historic district in 2002 and was declared a National Historic Landmark in 2005.
The scope of work includes the repair of the “Shadowood” texture concrete walls, and repainting the concrete to replicate the original acid stain system of the exterior. Also included is a complete new roof (approximately 50,000 square feet), and the installation of a traffic bearing membrane on a sun deck over the porte-cochere, Working closely with NPS Cultural Resources officials, the physical assessment was completed by HPZS in October 2019.
In 2020/21, HPZS prepared a detailed set of concrete restoration construction documents that included a complete tear-off and replacement of the existing roofing and promenade deck coating. HPZS also located contractors with the necessary background experience who could appropriately bid this complex project. The restoration and roofing work is now under contract and began in spring of 2022, with HPZS providing Construction Administration services.
