Developer finding ways to recycle material
The heavy equipment was already demolishing buildings and pavement as the ceremonial groundbreaking took place on May 23. Workers had already leveled many of the structures. They had already begun separating the remains into distinct piles of concrete, asphalt, structural steel, sheet metal and rebar for recycling.
“Everything that can be recycled is being recycled,” said Joe Ernst, president of srmErnst, one of the Alameda Point Partners group busy at Site A. “In our bidding we pushed for everything to be separated and recycled, with the value of recycled material offsetting demo cost. All of the ground-up asphalt and concrete will remain onsite and be used under streets and any exterior concrete structures and surfaces.”
Pavement has already been removed next to the Seaplane Lagoon where Phase 1 of the waterfront park will be built. “The next major operation in this area will be doing ground improvement in a 25-foot-wide band at the back side of the bulkhead,” said Ernst. “This will consist of soil cement mixing to a depth of 15 to 20 feet. Placing cement in the ground densifies the soil, significantly mitigating liquefaction risk which can put significant pressure on the bulkhead during a major earthquake and cause it to collapse,” explained Ernst.
“The bulkhead will effectively become a veneer,” said Ernst. “This is necessary because the Navy removed a lot of material from the front of the bulkhead when they remediated the lagoon.” The original bulkhead design relied on fill nearly to the top of wall to brace the wall and offset pressure from the other side. The Navy did not replace this after removing all of the contaminated soil in the lagoon next to the bulkhead.
Completion of the new infrastructure for phase one of Site A is expected within the next two years, with vertical construction of the new buildings commencing by year end. The first residential units are projected to be completed in the second half of 2019. The project will create approximately 2,500 direct construction jobs over the life of the project and serve as the catalyst for thousands of future jobs.
Once completed, the 68-acre master planned development will bring 600 market rate residential units, 200 affordable residential units and up to 600,000 square feet of commercial space, 15 acres of parks and public open space, and new transportation services and facilities, including the new ferry terminal on the Seaplane Lagoon.
