The City of Valdez New Harbor Development Project is a multi-year, phased project to build a new harbor basin and upland facilities on the south side of the old Hotel Hill site. The new harbor will include docks/moorage capacity, vehicle parking lot, additional vessel launch ramps, and support services. New access roads and pedestrian walkways will be included to provide increased waterfront accessibility.
• Increased moorage capacity
• Additional launch ramps
• Greater waterfront access for boaters and the non-boating public
• Additional local economic activity
• Opportunity for service industry development and support for the fishing industry
CONSTRUCTION UPDATE (PHASE 1 UPLANDS CIVIL WORK)
Harris Sand & Gravel (HS&G) continued implementing SWPPP and traffic controls.
Water, Sewer and Storm Drain Systems – Chlorinated and tested service water lines and fire lines at ramps. Installed backflow preventer and insulated enclosure at Ramp #3.
Ramp Abutments – Placed reinforced concrete slabs at abutments where future ramps will be connected.
Utilities and High Mast Lighting – CVEA set transformers and pulled conductors. Puffin Electric worked on grounding for street lights, installed hand holes, switchboard cabinets and lighting controls, erected street lights, pulled wire and began making switchboard connections. Puffin also assembled high mast light poles, lowering devices and fixture arrays for installation next month. HS&G extended trenching through bedrock and GCI installed their remaining of conduit near the West access. HS&G continued installing bollards at fire hydrant locations.
Waterfront Boardwalk and Sidewalk – Zastrow finished forming and concrete placement for boardwalk sleepers, sleeper keys, stemwalls, sidewalk, curbs, ADA ramps, utility pads, abutments and maintenance access bollards. Boardwalk construction continued with placement of sleepers, brackets, stringers, bull rails, guardrails and handrails. Backfilling along boardwalk stemwalls continued.
General – Sitework continued, including breaking bedrock and excavating the west and east ditches; shaping the West access mound; placing topsoil and hydroseeding throughout the site; preparing grade for curb, gutter and sidewalk; completing placement of Type II-A subgrade except in areas Western Marine is permitted to use for access and staging for breakwater construction; finish grading at Abutments and around East entrance and East side curb and gutter; placing Filter Rock to finish grade at NW slope of East fill. Started installing signs – some will be deferred for installation with paving. Asphalt paving and related leveling course and striping items will not be performed this year. Overall, the remaining Phase 1 construction work is approximately 93% and on track for completion in November 2016.
Ripper Test - A test was conducted during low tides to evaluate the effectiveness of an X60 Xcentric ripper attached to an 800-class excavator for removing fractured and/or solid bedrock in the West outcrop and Drive-Down Flat Basin (east) areas. It was anticipated, but unfortunately not demonstrated, that this ripper would provide a cost-effective alternative to drilling and blasting for removal of some in-water rock. Although the ripper was not successful, subsequent testing with a rock bucket at the east area demonstrated that fractured bedrock could be removed.
In addition to Phase 1 work, HS&G continued delivering rock to Western Marine for construction of the breakwaters.
EMC provided general observations, inspected pipe, conduit and rebar installation, tested soil compaction and sampled and tested concrete for curb and gutter, abutments, utility pads and boardwalk sleepers.
R&M Consultants (R&M) continued to work with the City (COV) on design packages for future phases of the new harbor. The 95% design for Drive-Down Ramp and Float package is due by October 21. R&M continued to provide limited construction phase services for the Uplands Civil Work. R&M and Arcadis continued to work with the COV to develop and evaluate options to minimize the quantity and cost for removing in-water rock. Overall sequencing of the remaining work packages is dependent on Western Marine Construction’s (WMC) completion of the USACE work and other factors. The project team has been reviewing and discussing this issue with WMC. The focus during October and November 2016 will be on timing for bidding and performing the remaining work packages. R&M and COV representatives will start conducting Substantial Completion inspections in October.
USACE NAVIGATION IMPROVEMENTS
The USACE is administering WMC’s performance of the dredging and breakwater contract. WMC was granted a Temporary Land Use Permit from the City of Valdez to use the west end of the Uplands site to handle and store rock and access the west breakwater ramp, expediting the breakwater construction process. WMC continues dredging the new harbor basin, hauling rock from Valdez Glacier Quarry, and transporting rock by barge and trucks for construction of the breakwaters. Breakwater construction is several months ahead of schedule and it appears the South Breakwater might be constructed to approximately elevation +10’ by the end of the 2016 construction season. Finish elevation of the breakwaters will be +19’. The COV is coordinating with WMC and USACE to widen the maneuvering channel and create more basin area at the west end. During October and November, we anticipate having discussions with WMC and USACE to reach mutually acceptable conditions for allowing access to the new harbor basin for a future COV contractor to begin installing piling and floats in fall 2017.
