New Kings Sports Arena
Sacramento, California
|
Construction on the foundation piles for the new $477 million Kings Sports Arena to be located in downtown Sacramento, California has begun following the demolition of the Old Downtown Plaza. Malcolm, under contract with Turner Construction, received a multi-million dollar Design-Build contract to install the foundation system for the arena and the nearby practice facility. Our Value Engineering proposal was based on almost 1,000 Drilled Displacement (OMEGA) Piles ranging between 18-in and 24-in in diameter. The piles are schedule to be installed in less than one month as part of an accelerated construction schedule.
As a creative approach to project delivery for the accelerated schedule Malcolm installed and tested several piles within the first available area on site during demolition. The results for compression load test of up to 1,300 kips confirmed the viability of Malcom's Value Engineering proposal and the chosen pile system and diameter for the new foundation.
The biggest challenge for the project will be the small foot print of the construction site and coordination of material delivery. Another challenge will be working with the one access ramp to the 20-ft excavated site
Another project for the new sports complex involves reinforcing the practice facility with about 125 highly loaded Micro Piles which will be installed mostly under restricted headroom.
"Pile design has commenced and we are looking forward to install the first production pile before Thanksgiving. Malcolm is very proud to be part of Turner's construction team on such high scale project in the middle of California's capitol." Commented Terry Tucker, Malcolm's Project Executive.
The King's plan to play their first game in the new sports facility during the 2016-2017 season.

Oil Field Abatement for the
New Gerald Desmond Bridge
Long Beach, California
|
The Gerald Desmond Bridge, located in the Port of Long Beach, California, is a critical link in the nation's trade system and is a major costal commuter corridor. It is estimated that 15 percent of all containerized cargo imported into the United States travels across the Desmond Bridge. The bridge was built in late 1960s to connect Terminal Island, the heart of the port complex, with the Long Beach Freeway. Currently the bridge can no longer handle today's traffic volumes and is not high enough for the next generation of high capacity cargo ships. The replacement bridge will ensure commuter safety, improve traffic flow and protect the Port of Long Beach's role as a major international trading hub.
The New Gerald Desmond Bridge approach sits in the Wilmington Oil Field, one of the largest active oil fields in the continental United States with more than 6,000 operational wells. In order to construct the new bridge all active and inactive wells that interfere with the new bridge's foundation system had to be decommissioned and partially removed. Malcolm/ZEI under contract with OXY Petroleum was hired to decommission a total of 23 wells. The decommissioning process involved capping the wells and removing the surface casing, conductor pipe and well pipe to an average depth of 195 feet below grade.
"The idea was simple but the execution was more challenging because the well casing had to be removed without disturbing the existing ground around it," commented John J. Malcolm, Project Manager.
After determining that the well casing was not as plumb as originally thought, Malcolm/ZEI developed a new approach that involved oscillating and rotating an oversized temporary steel casing over the well casing to encapsulate it and then removed the well casing from within the temporary casing from the top down.
Once the well casing and all of the native material inside the temporary casing was removed to the desired depth a low strength self-compacting concrete was placed using the tremie method to backfill the excavated shaft. The temporary casing was extracted as the low strength concrete was placed to prevent disturbing the surrounding soil and nearby structures.
Construction of the new bridge began in 2012 and is expected to be completed in mid-2016. The project is estimated to generate, on average, 4,000 jobs per year. The project is being funded jointly by the Port of Long Beach, Caltrans, Metro and the U.S. Department of Transportation.

Deep Soil Mixing on the Florida Coast
Jade Signature Luxury Condominiums - Miami, Florida
|
Malcolm Drilling just finished the foundation work for "The Jade Signature," one of Miami's newest high rise buildings currently being constructed by Suffolk Construction. This 57-story luxury condominium project is located on the Atlantic Ocean coastline in Sunny Isles Beach, Florida. One of the many unique aspects of this project is its 3-levels of underground parking, a first of its kind for the low lying coastal areas of South Florida, called for a one of kind design to address below water level construction.
The project site sits directly adjacent to the Atlantic Ocean, with groundwater located almost immediately below the surface. The project geology included approximately 15-ft to 30-ft of beach sand, a 10-ft layer of peat overlaying layers of porous limestone and sand which allowed water to flow freely through the ground and the project site.
Malcolm implemented Deep Soil Mixing (DSM) as an alternative to numerous sheet pile cofferdams and tremie seals for the construction of the building's foundation. The unique design called for both the installation of 35,000 CY DSM, to resist hydrostatic pressure acting against the bottom seal along with 1,100-lf of DSM perimeter hydrostatic cutoff. The DSM was successful as it provided a deep (up to 43'), and dry excavation for the subterranean parking around the structure and beneath the remainder of the site. The DSM bottom seal, or plug, was comprised of overlapping soil mix columns extending to depths of 15-ft below the bottom of the planned building excavation. In building this DSM plug, every square inch of the approximately 2-acre site was treated with DSM. A DSM perimeter wall was installed to act as both support of excavation and hydrostatic cutoff. Large, closely spaced steel beams were used to support the wall without requiring internal bracing or tieback supports. An internal, unreinforced DSM wall was installed around the tower footprint, the deepest section of the excavation. Additionally, 317 EA 36-in in diameter and up to 155-ft deep Auger Cast piles were installed. Also, 500 ea. 18-in auger cast piles where installed from original grade elevation penetrating the DSM plug in order to provide the necessary uplift resistance.
"The design worked better than expected. The DSM solution allowed the project to proceed on schedule," commented Chris Sammon - Malcolm's Project Manager.
