The first part of the project involved relocating and re-handling approximately 140,000 cubic yards of sand onto a shallow plateau to begin the creation of the land. CASHMAN relocated the sand within the site to create the landfill, using the clamshell dredge Dale Pyatt, and dozers to create the site. Innovative soil vibro-compaction methods were utilized on the re-handled material to provide deep compaction of the fill, thereby reducing future settlement. Another 166,000 cubic yards of crushed granite were transported in seven shiploads by the bulk carrier MV Balder from Canada and offloaded via conveyor belt in the landfill area. CASHMAN relocated the granite within the site using loaders and dozers. With bulkhead wall and pile cap design provided by PND Engineers of Seattle, WA, the contract also included: Construction of a cast-in-place 1,250-linear foot cantilevered retaining ‘splash wall’ on the south and east of the site as storm protection; Installation of 1,350 linear feet of sheet piling in an open cell pattern on the north and west; Construction of 1,350 feet of reinforced concrete pilecap on top of the new sheet pile bulkhead; Extension of multiple utilities into the newly reclaimed land; Construction of bridge approaches; Final site grading. CASHMAN utilized its own East Coast resources to man the US-flagged dredge Dale Pyatt and to ensure the project schedule was met. Besides the Dale Pyatt, CASHMAN transported a sheet piledriving crane and hammers, and earth-moving and compacting equipment to the site.
The project employed over 25 local subcontractors and suppliers throughout all phases of construction. All reclamation and marine construction work was performed in proximity and without damage to the Royal Naval Dockyard, a listed building of historic significance. The first phase of construction of Cross Island was completed in August 2016. The project attracted avid local attention and was reported on in detail by the local newspaper, The Royal Gazette.
