Description

Specifications include, but are not limited to: The project scope includes replacement of the northbound Providence Viaduct and its associated ramps and structures with new structures to restore structural sufficiency and to alleviate chronic traffic congestion on Interstate 95 through downtown Providence. The Viaduct was constructed over 50 years ago to carry I-95 through Providence and is the third busiest interstate in New England. Although it was originally designed to handle 57,000 vehicles daily, the volume is now over 200,000 per day. There are six bridges within this project that are structurally deficient or functionally obsolete, requiring frequent and costly repairs in order to maintain functionality of that area of I-95. The proposed project will also yield significant safety improvements over the current configuration. The Base Technical Concept (BTC) that has been developed includes the reconstruction of the Providence Viaduct Northbound, which includes replacement of selected bridges, roadway reconstruction and other associated work. The bridges and retaining walls will be as required to support the proposed roadway layouts required for the final highway design. It is anticipated that the scope of work under this PROJECT will include the elements defined below. However, these elements are subject to change upon prior to the issuance of the RFP. Major project elements may include but may not be limited to the following: a. Survey b. Geotechnical investigation, analysis and design c. Subsurface Utility Engineering, coordination, relocation and/or temporary support and protection in place d. Bridge and wall (including temporary and/or retaining) analysis and design e. Highway design and construction f. Temporary traffic design and management as required to support staged construction g. Traffic engineering and/or Traffic Data Collection h. Design and Construction Quality Assurance/Quality Control i.

Historical/Cultural (e.g., Section 4(f), Section 6 (f), Section 106) k. Final Design and Construction of all elements l. Employment of Accelerated Bridge Construction (ABC) techniques
