Archive August 2006 IRIB Construction Update
Route 1 Roadway
The new traffic pattern in the vicinity of the Inlet will remain in place until construction of the new bridge is completed, currently expected to be in late 2010.
Fresh Pond North
Pond is complete and has an animal exclusion fence installed to protect vegetation from being damaged until sufficient growth can be established. Estimated removal is December 2007.
Fresh Ponds South
West - Pond is complete except for final seeding which needs to be done in the specified planting window (April-May). An as-built has been completed by the contractor for review by the Army Corps of Engineers.
East - Pond is incomplete until material used as the bridge approach surcharge can be removed and placed into the existing pond to construct the pond per plan. The area completed (+/- 75%) has been surveyed and temporarily seeded until completion can occur (estimated May 2007).
Fresh Pond South Bridge
The bridge has been constructed and paved and is considered complete except for the corresponding guardrail that needs to be installed which is estimated to be done by August 2006. The temporary roadway has been removed and the new tidal gut has also been excavated to join mitigation sites.
South - This approach is currently at an elevation of 18.0’ with continued progress of constructing the MSE walls and soil embankment to a final elevation of 43.2’. The surcharge material will take the embankment to elevation 51.0’ to aid in quicker settlement times and is estimated to be completed late fall of 2006. The anticipated amount of settlement is to be completed around May of 2007 when removal of the surcharge, construction of the drainage system and concrete MSE walls can be started.
North - This approach is currently at an elevation of 23.0’ with continued progress of constructing the MSE walls and soil embankment to a final elevation of 43.2’. The surcharge material will take the embankment to elevation 51.0’ to aid in quicker settlement times and is estimated to be completed late fall of 2006. The anticipated amount of settlement is to be completed around May of 2007 when removal of the surcharge, construction of the drainage system and concrete MSE walls can be started.
Doug Robb provided an overview and update on the current status of the Design-Build project being developed for the new Indian River Inlet Bridge at the July 11, 2006 public meeting. On July 5th the Department issued a Request for Qualifications (RFQ) to prospective Design-Build teams. Responses to the RFQ will be used by the Department to identify a "Short List" of up to 3 teams demonstrating their capacity to perform the work associated with the new bridge. The "Short List" is currently scheduled to be announced on September 1st.
The Department also has issued a Draft version of the Request For Proposals (RFP) package that will be issued to the short-listed teams this September. The RFP package provides Instruction to the Proposers and contains the appropriate Contract and Reference Documents detailing the roles and responsibilities of the Department and the Design-Builder. Some of the selection criteria that will ultimately be used in determining the successful proposer were discussed. Some of the considerations will include: maintenance requirements, proposed impacts to the existing roadway contract, proposed completion date, design and aesthetic concepts, construction techniques, management approach, quality controls, and price. A draft version of the RFP is currently posted on the project website (www.irib.deldot.gov) and is available for comment through August 9th.
Award of the bridge contract is anticipated by February 2006 with a required completion date no later than September 30, 2010. The first traffic is expected to be on the new bridge by the end of Year 2010.
Road 50A Improvements
Soil boring fieldwork has been completed along the existing roadway. Initial lab analysis has confirmed the roadway is situated on a very soft thick clay layer, like the new SR-1 roadway approaches. These soils do not allow for simple, safe, and durable retaining structures to be constructed along Road 50A while the permitting and mitigation that would be associated with wetland impacts created from substantial fill placement (>1 foot) would be a very time consuming and costly.
In order to provide more immediate relief to the flooding problems, the Department has identified with assistance from residents from South Shore Marinas, approximate limits for the three lowest lying areas along Road 50A. The Department will be looking to provide a more uniform roadway elevation along Road 50A that is more consistent with its highest points as well as the privately maintained roadway within South Shore Marinas. This will most likely be accomplished by placing multiple layers of hot-mix within the low areas. The Department's design staff is currently preparing cost estimates and will be requesting funding to perform the work. The funding availability will determine when the work can be performed. The order of priority for correcting the problem areas will be to address the lowest elevations first. Funding availability and time frames to complete the work should be better known by the next progress meeting in September.
Ocean Ridge West / Fresh Pond Access Road
DNREC has developed some preliminary plans for landscaping and bollards to separate the public on the fresh pond north access road from the community. A meeting was held after the public update on July 11, 2006 to discuss the proposed plan. Sharon Mahony (resident) was onsite to view the plan and will take it back to the community’s board to see if this is sufficient. If acceptable a tentative planting time of fall 2006 could take place installing the native plants by DNREC.
