Four Seasons Manele Bay Renovation Project

Massive renovations have been completed at the Lanai at Manele Bay, Four Season Resort. A portion of the project involved lowering the level of makai pool, along with widening the entire usable area in order to construct additional pools, lounge areas and cabanas. In order to increase the usable space at the pool area, mass excavation was necessary right up to the foundations of the two adjacent wings (dolphin and plumeria wings) of the hotel.
Worried about potential settlement (sinking) during excavation, engineers required several of the existing column footings to be underpinned with a deep foundation system, to keep the buildings secure and in place. 5.5" diameter cased micro-piles were installed as the deep foundation element to help shore up the two hotel wings. Our limited access drill rig installed the piles a minimum of 15 feet into the sound bedrock, in order to provide enough load capacity to fully support the above structure.
With the demanding schedule put forth by the ownership, and the fact that the entire project must be completed by the end of March 2016, mass excavation had to occur right behind us, mandating an on time finish. They were literally nipping at our heals!
Chance "under footing" bracket couples to the top of our micro-pile system and then anchors permanently to the existing footing. Each one of these brackets has a load carrying capacity of 46,000 pounds. With our hydraulic jacking system, we actually pick the building up off the soil in order to transfer the load to the piles. There is also a heavy duty 70,000 pound bracket option if higher load capacities are needed.
The photos show you just how close the excavation came to the hotel footings/foundations. We were able to install our drilled and cased underpinning system in just under two weeks keeping the makai pool project moving forward and on schedule. Nordic PCL was so pleased, they decided to have us install additional piles to go beneath two separate retaining wall systems that were to be constructed.

Railcraft’s ability to manufacturer a wide range and varying types of aluminum systems allows them to satisfy a broad range of design requirements while maintaining the flexibility of providing matching colors, looks and themes for their projects.
