PROJECT: STORMWATER IMPROVEMENTS – FASSNIGHT CREEK AT THE SPRINGFIELD ART MUSEUM (2019PW0032)
Based on feedback from contractors, the following revisions have been incorporated into the Stormwater Improvements to Fassnight Creek at Springfield Art Museum (2019PW0032) project:
- Simplified the void-filled rip rap specification to include locally sourced river gravel infill materials,
- Simplified void-filled rip rap installation specification to allow a layered approach,
- Reduced the overall quantity of void-filled rip rap specified in the plans and, where feasible, replaced with equivalently rated turf reinforcement mat,
- Allowing for equivalent articulated concrete block mat in lieu of void-filled rip rap,
- Reducing the amount of sanitary sewer work and retaining the existing sanitary sewer infrastructure in the vicinity of the Kings Ave. bridge,
- Lining existing clay pipes, that are to remain in-place, with a cured in place pipe (CIPP) prior to construction to provide additional structural integrity to the existing pipes,
- Providing sewer by-pass pumping by City crews for up to 7 days,
- Included a sanitary sewer contingency Job Special Provision to address and share the risk associated with the sanitary sewer work,
- Allowing additional flexibility for contractors regarding the notice to proceed date by granting a longer period following contract execution to identify, and mutually agree upon, a notice to proceed date for construction of the project, and
- Provided local soil disposal site on City owned property for use, at Contractor’s option.
The City of Springfield is seeking qualified contractors to perform the demolition of existing reinforced concrete bridges and existing concrete channel to restore approximately 1,000 linear feet of Fassnight Creek.

Brookside Ave. Construction includes sanitary sewer main improvements, roadway alignment and paving modifications on E.
