Wilshire Boulevard Temple

The dome interior is 70 ft in diameter and rises 150 ft from the temple floor with suspended coffered plaster dome ceilings. The structure suffered from water infiltration through the concrete dome structure and low-slope roofs, cracking of cast stone and concrete facades, damage to inlaid exterior stone tile, cracking and displacement of the stone base, and stains on the interior plaster dome ceiling. Our work included the following:

• Condition survey of domes, copper roof, low-slope roofs, rose window, and parge-coated facade
• Interior survey of dome ceiling, stucco, and Zenitherm finishes
• Cataloguing material conditions
• Identification of deterioration mechanisms, including those inherent to materials and those based on mechanical performance or construction
• Investigation of roofing and drainage system failures

SGH developed a conservation plan to address damage to the building enclosure and domed ceiling. As part of the overall revitalization program, we developed construction drawings and specifications that included roofing, waterproofing, facade, and rose window repairs. SGH also provided construction administration services, including review of shop drawings and contractor requests for information, coordination and water testing of mockups, and site visits to confirm general compliance with the contract documents.
