Jade Signature

SGH consulted on the design of below-grade and plaza waterproofing, curtain walls, sliding door assemblies in the residences, balcony waterproofing, and roofing. Highlights of our work include the following:

• Reviewing the building enclosure design and providing recommendations to improve performance
• Assisting with the system selection for waterproofing, roofing, balcony wearing surfaces, and concrete coatings
• Consulting on the waterproofing for the below-grade portions of the building, which extend over 40 ft down, well below the water table
• Helping develop details to integrate the various enclosure systems, including those that intersect with the exposed concrete structure, such as the curtain walls, balcony and plaza waterproofing, and roofing
• Reviewing proposed details for the curtain wall systems for the lobby
• Visiting the site to observe below-grade waterproofing installation
• Answering questions from the construction team related to the building enclosure construction

We also analyzed drainage from the large Level 2 balconies that hang over the plaza on the on the east (ocean-facing) elevation. SGH estimated the peak flow rate for the plumbing engineer’s use in their design of the drainage system and evaluated the capacity of the proposed drainage details.
