Consultant services to perform preliminary and final design of county owned, generally OffSystem, bridge replacement projects across the state. There are 24 individual bridge replacement projects. MDT will obtain the appropriate geotechnical engineering for all sites through a separate on-going contract. Preliminary geotechnical recommendations will be provided to the design firms to support preliminary design. The design firms will coordinate with the assigned geotechnical engineer to complete the final design. Environmental engineering through the Scope of Work (SOW) milestone will be completed by MDT through an existing on-going contract and made available to the design firms. The design firms will be expected to complete all subsequent post-SOW environmental activities and permitting, and all other project design activities necessary to complete the work. The project will be funded by the State of Montana’s Local Road and Bridge Account in the state special revenue fund and in accordance with Montana Code Annotated § 15-70-132. MDT’s intent is to leverage the state funds toward future federal aid match. Therefore, project delivery will need to fulfill federal aid requirements. Cost effective solutions that fulfill the project goals are expected in order to fund all of the proposed projects. MDT is utilizing a Program Manager to assist in delivering these projects. The Program Manager will work with the design firms and MDT to coordinate delivery of each project. Collaboration with the counties and MDT’s Program Manager will be required. MDT’s intent is to bundle either some or all individual bridge projects and award as multiple design contracts depending on all responses to the RFP.
