The Washington Suburban Sanitary Commission (Commission) is preparing Contracting Opportunities for Contractors that specialize in rehabilitation of sewer mains, manholes, and laterals. These Contracts will be Indefinite Delivery Indefinite Quantity (IDIQ). The Contracts are competitively bid, firm, fixed-priced construction contracts to be constructed following Commission approved Standard Specifications and Standard Details for pre- established Unit Prices within residential areas. The Commission will be advertising a Request for Proposal (RFP) through its Supplier Portal. The Prime Contractor awarded these projects shall have a team capable of executing repair, rehabilitation, and replacement of sanitary sewer mains, manholes, laterals, and related sanitary sewer infrastructure in an expeditious manner.
Planned work is currently being designed in multiple sewer basins across the Sanitary District. This planned work involves the rehabilitation, replacement and/or relocation of sewer mains and manholes in public rights-of-way or within WSSC easements in various locations in Montgomery and Prince George’s Counties, Maryland. WSSC anticipates rehabilitating more than 65% of its sanitary sewer mainline, laterals and manhole systems by utilizing trenchless technologies such as structural lining and grouting. Work involving pipe bursting and open cut, and sewer manhole replacement will also be required. The Contractor will be responsible for temporary and permanent patches; mill and overlay will be performed by others and is not a part of this contract.
The COMMISSION intends to award a Contract to multiple Prime Contractors for a base term of two (2) years with two (2) two-year option terms that can be exercised at the discretion of the Commission. Vendors are not guaranteed any work under this contract. Task Orders will be awarded on a competitive and/or negotiated basis. The estimated quantities of work to be completed for the residential area IDIQ contracts, based upon total Contract value are as follow:
|Residential IDIQ Contracts:|
Sewer Mainline Lining
Sewer Mainline Grouting
|Sewer Mainline Relay / Pipe Bursting||15 %||Manhole Rehabilitation||10 %||Miscellaneous Activities||10 %|
After Contracts are awarded, the contractor will be assigned Task Orders. Each Task Order shall include a set of design documents prepared by the Commission. The Design Documents will reflect the necessary coordination to be followed by the Contractor in order to maintain the operational integrity of the collection system (i.e. bypass pumping, etc.). Design Documents may include but are not limited to the following:
All interested vendors are required to be registered in the WSSC Supplier Portal before they can view, receive, and bid on solicitations.
