Question:
Our review of the roadway geometry that was provided in the BTC has found that a minimum stopping site distance of 200’ has not been provided for ramps DB-2, CB-2, CB-3 and AC. This stopping site distance of less than 200’ will introduce additional design exceptions for these ramps. Are the D/B Proposers to assume that these additional design exceptions will be approved by RIDOT and FHWA and can be carried thru the proposal design and final design?

Question:
The BTC shows the following substructures as being re-used: Smith Street West Abutment, Ramp BR-4 North and South Abutments. Since they are being shown as re-used in the BTC, will the design builder be required to certify and/or be retrofitted to meet current AASHTO and RIDOT design criteria, including reinforcement strength and detailing? Or can they be assumed to be acceptable as shown in the BTC?
Answer:
There has been no investigation of substructure condition or load testing performed on the existing substructures to be reused. Reuse of substructures, including those identified to be reused in the BTC, requires certification by the Design-Builder that these components are suitable for reuse to meet current design criteria.

Please refer again to Volume 2, Sheet 8 where in Phase 5 Ramp CD-DB/I-95 is shifted east and will require redesign and construction of the Park St/Hayes St traffic signals as well as other electrical boxes. Who owns the control boxes and where can they be relocated?
Answer:
Four electrical boxes are located along I-95 across from Hayes Street in Providence. Moving from north to south based on an interpretation of record information: 1st box is an electric meter and traffic signal controller for the Park Street and Hayes Street intersection. 2nd box is an electrical meter for the traffic signal controller at the intersection of Smith Street and Park Street (State). Please note conduit run heads north along Park Street. 3rd box is an electrical meter for the street lights for Park Street, Avenue of the Arts, Francis Street, and Hayes Street (City) 4th box is electrical and conduit runs between the electric manhole at the Park Street and Hayes Street intersection, this box, and the electric manhole at the Smith Street and Park Street intersection (NGrid) The DB Team shall evaluate the following: Keeping the 1st box near the traffic signal at Park Street and Hayes Street intersection. Moving the 2nd box near the signal at Smith Street and Park Street intersection. Keeping the 3rd box near the Park Street and Hayes Street intersection to avoid major revisions to the existing conduit run Coordinating with NGrid to determine the function of this box. As the project was only preliminarily advanced, the utility relocation of these boxes has not been advanced.

What testing/calculations has RIDOT completed to determine the physical condition and load carrying capacity of the piles in order to confirm that re-use of piles at these locations is technically feasible?
Answer:
The nominal capacity of piles to be reused was assumed to be the twice the original design capacity (assuming a Factor of Safety of 2 on design capacity). The physical condition of the piles will need to be observed by the DB Team during construction to verify if there is corrosion or damage that will affect the remaining design life, and a field testing program (static load test or dynamic pile testing) will need to be performed for each pile type and capacity to verify the in-place capacity by the DB Team.

Question:
Please refer to sheet 7 of BTC Volume 2 Smith & Park Street Bridges. The Longitudinal Section indicates a minimum vertical clearance of 15’-1” under I-95 NB. Has the agency been granted an exception to the 16’-0” minimum federal standard?
Answer:
The referenced vertical clearance shown in the BTC is the minimum clearance that would be found acceptable to RIDOT for this location. A proposal that increases this clearance would be looked upon favorably during the review process.

Question:
1. Specification section 3.13 Bridge Design and Other Structures, sub section 3.13.16 Disallowed Alternatives, Paragraph A stipulates that “Elimination of any of the spans of the proposed Viaduct NB Bridge by means of filling between the spans shown on the BTC drawings” will not be accepted. Please clarify the Department’s reasoning for prohibiting this approach as an ATC.
Answer:
ATCs are permitted for filling spans. Spans filled need to avoid impacting/overloading existing structure foundations. Additionally, spans filled need to not interfere with sight distance criteria, need to allow for all structures in the area to be inspectable, and not compromise aesthetics. Any ATCs that fill spans need to clearly identify how the above mentioned items are addressed.

Question:
Please provide details of the design submittal review process expected for the 6 bridges requiring preservation activities to be complete within 12 months of NTP. This was discussed in the pre-bid meeting, but the answer was not very clear. Is the work expected to be complete directly from the plans provided in the RFP or is there design to be complete and design submittals to be reviewed/approved prior to construction? If so, please detail these submission requirements, which will need to be tailored for the short duration. With an expected NTP at the end of June, design work potentially to complete and have approved, winter conditions, and construction, 12 months is a very short period to complete the work. Preservation work often includes work that is very difficult to complete in the winter without significant extra cost.
