1. Procurement Basis and Invitation
This solicitation is intended to comply with MoDOT Engineering Policy Guide Section 136.4, the Brooks Act
qualifications-based selection requirements, 23 CFR 172, and applicable Missouri law for procurement of
professional engineering services. Cost information shall not be included in the Statement of Qualifications
unless and until the City initiates negotiations with the highest ranked firm.
The City of Dardenne Prairie, Missouri, invites qualified engineering consulting firms to submit Statements of
Qualifications for the Weldon Spring Road (Phase 1) Improvements project. The City intends to select the firm
whose qualifications, experience, technical understanding, capacity, and past performance are most
advantageous for successful delivery of the project in accordance with federal-aid requirements.
This solicitation is publicly advertised in accordance with MoDOT LPA requirements to ensure full and open
competition.
2. Project Background and Need
Weldon Spring Road (Phase 1) extends generally from Technology Drive to Henning Road and serves
residential neighborhoods, school traffic associated with John Weldon Elementary School, nearby churches
and businesses, and connections to the local and regional bicycle and trail network.
The corridor is generally a two-lane roadway with constrained drainage collection, limited curb and gutter,
aging pavement, and pedestrian facilities that do not adequately support current multimodal demand. The
City's grant application identifies safety concerns, school access and circulation issues, drainage
deficiencies, limited illumination, and the need for safer pedestrian and bicycle connectivity along the
corridor.
The selected consultant will be expected to refine the project concept and advance the work in a manner
consistent with applicable City, County, MoDOT, FHWA, ADA / PROWAG, MUTCD, and AASHTO requirements.
3. Anticipated Project Improvements
* Pavement rehabilitation, resurfacing, and associated roadway reconstruction where required.
* Realignment and safety improvement of the Weldon Spring Road / Technology Drive intersection.
* Addition of curb and gutter, storm sewer improvements, inlets, grading adjustments, and related drainage
work.
* Widening and striping improvements, including a center turn lane or other safety-related lane
configuration in the school frontage area as appropriate.
* Construction of a 10-foot shared-use path and related sidewalk transitions, ADA curb ramps, and
pedestrian connections.
* Enhanced crossing treatments, including high-visibility crosswalks, raised crossings where appropriate,
RRFBs, signing, pavement markings, and channelization features if warranted.
* Street lighting, pedestrian/path lighting, and related electrical components, including solar-powered
devices if incorporated into the final design.
* Driveway aprons, restoration, traffic control, and other appurtenant work necessary for a complete and
buildable project.
* Right-of-way and easement support, utility coordination, and utility relocation planning / coordination as
required.
