Question: RFP Part 1 Section 8.4 states “The Proposer shall include in their presentation a rendering(s) of the landscape and streetscape concepts they are proposing…” Can RIDOT please clarify any rendering requirements for the presentation? Is “landscape and streetscape” intended to refer to the actual landscape/streetscape design or is the intent for Proposers to provide general, perspective views of key elements of the Project?
Answer: These landscape and streetscape elements are not required for the presentation. The sentence "The Proposer shall include in their presentation a rendering(s) of the landscape and streetscape concepts they are proposing to design and construct as part of their proposal" can be deleted from this section of RFP Part 1.

Question: Per RIDOT standard Specification Section 841, Pre-Construction and Post-Construction Surveys need to be performed on both interior and exterior walls of buildings. Per the RFP, pre-construction and post-construction surveys need to be conducted on all structures located within 200 Ft of Vibration inducing activities. Per Section 841, the interior surveys should include all walls, floors, ceilings, doorways, windows, etc.. Some of the buildings that fall with-in that requirement include but are not limited to the Omni Providence Hotel, The Foundry Building, and Providence Place Mall. These are a few of the many large buildings with very difficult coordination challenges to conduct interior surveys of all walls, floors, ceilings, doorways, and windows. Due to the long survey durations required to perform complete interior building surveys, would it be acceptable to perform pre-construction and post-construction interior surveys on the basements and first floors of buildings only?
Answer: Limits for this Pre- and Post-Construction survey for buildings over 3 stories within the 200 ft limits can be revised to the basement and first floor interiors, and entire exterior of the building.

Question: Form E, Certification for Dumping Facilities, requires us to list prices for disposal of several categories of contaminated soil disposal. The mandatory Specification 202.9901 appears to require payment based on the actual cost of the disposal at the licensed facility. What are the rates on Form E used for and how are they used in the evaluation of the technical proposal? If these are to be the rates for payment for contractor cost of disposal of contaminated soil, how will these rates be interpreted. The cost at the disposal facility changes each year, typically increasing. We cannot know the future rates for disposal beyond this year. Should we be listing current prices and if so, will any future increases be paid by the State in addition to the current price? Should the form be changed to eliminate the rates and only include a certification that the contractor has identified adequate receiving facilities for each category?
Answer: The current disposal facility pricing can be listed for informational purposes with the understanding that the actual cost charged by the facility at the time of disposal is what will be used when determining payment. Actual reimbursement will be based on actual billed price.

Question: The 2011 Geotechnical Interpretive Report included in the RFP recommends an existing pile corrosion reduction of 1/8-inch for all surfaces. This is based on a 1/16-inch section loss given the age of the existing piles, unless more corrosion is discovered when the piles are exposed, and an additional 1/16-inch for potential future corrosion. The BTC indicates that existing piles be re-used and supplemented. The existing pile load test report (PDA 578 N abut.-REVIEWED by GZA.pdf) provided in Amendment 8 indicate that 1/16”-inch section loss was observed on an existing ~30 year old pile tested at the north abutment as part of the Southbound Viaduct project. Only the portion of the pile within the fill layer was evaluated for corrosion loss. The existing circa 1963 H-piles supporting the Northbound Viaduct likely have experienced greater than 1/16” section loss in the fill since they have been in the ground almost twice as long as the Southbound Viaduct pile that was tested. The organic soils present below the fill and along much of the Northbound Viaduct alignment are expected to be significantly more corrosive than the fill soils. Taking into account the existing corrosion rates measured from the tested Southbound pile and including future corrosion for a 75-year design life, there may be no viable section remaining for pile reuse. Does RIDOT want to reconsider the recommended assumed section loss for the 1963 H-piles? Where the existing piles are proposed to be reused, should they be extracted to evaluate the corrosion loss within the fill and organic soil layers? If yes, how many piles per existing substructure should be extracted and evaluated for section loss? How will the design-build team be compensated if a larger section loss is observed when the piles are exposed, and the existing piles are not viable for re-use?
Answer: The assumed section loss of 1/8 inch should be used for design, however the actual corrosion of the existing piles shall be measured once they have been exposed during construction, and this corrosion rate should be used to estimate future corrosion for the remainder of the pile design life. Depending upon the actual observed corrosion rate, supplemental piles may need to be driven to provide the necessary design capacity. Based upon review of available literature, it is anticipated that the highest corrosion rate will be in disturbed soil (fill) above the groundwater level. Piles driven in undisturbed soils below the groundwater level with little exposure to oxygen are anticipated to have lower corrosion rates at about 0.00047 inches per year. While it would be desirable to extract pile(s) to observe the corrosion rate at various depths, it is anticipated that this may not be possible due to the length of the piles and the time that they have been in the ground. The design-build team may opt to attempt this, however. If corrosion is greater than anticipated, additional required piles will be eligible for additional compensation subject to change order request procedures.

Question: A response to a question on 3/18/20 stated that a cover sheet indicating which sheets are unchanged from the BTC plans should be provided within the proposal submission. Please confirm that this cover sheet is not required if the plans submitted as part of the Proposer’s Technical Proposal satisfy the RIDOT 10% design submission requirements as stated in Part 2 Section 3.4.4.2 of the RFP. The BTC plans provided as part of the RFP exceed a 10% design level as described in Part 2 Section 1.2.3 of the RFP. Therefore, it will not be required for the DB Team to assume responsibility for details included in the BTC exceeding the 10% design level.
Answer: This cover sheet is not required if a Proposer's Technical Proposal satisfies RIDOT 10% design submission requirements. While the BTC plans in some places exceed a 10% level of design, DB Teams are responsible for certifying any portions of the BTC incorporated into their final design. The DB Team is fully responsible for the design and will stamp and seal all drawings in the final design as the Engineer of Record. If the DB Team chooses to use any portion of the BTC, they do so accepting full responsibility (and liability).

Question: Section 3.11.1 of the RFP references RIDOT’s INFRA Grant Application and building the project as a smart corridor. The INFRA Grant Application, however, does not detail the specific types of ITS/CAV applications to be required in this project. The INFRA Grant Application states that the project “could be a staging ground for a pilot that would use V2I communication to let motorists know that there is an active construction zone, using smart traffic apps for freight mitigations”. Is this a requirement for this project? If so, please provide the Concept of Operations and software requirements for the smart corridor for the final conditions as well as during construction. Do we need to provide fiber optic cable connectivity between the RSU’s and RIDOT TMC so the TMC operator(s) can download MAP revisions to the RSU to support the smart traffic apps that will let motorists know there is an active construction zone and to assist with mitigating freight congestion?
Answer: Incorporation of this type of communication/smart corridor, or similar technology, will be looked upon favorably during technical review. Any fiber connectivity required based on the system proposed by the DB Team is the responsibility of the DB Team.

Question: The Chalkstone RR Bridge shows 2ft wide cribbing (limited by intruding into the RR ROW) and limits allowable soil bearing pressure to 2000psf. Based on the 172kip jacking load, the area available is insufficient. Please confirm that the allowable bearing pressure is indeed 2000psf and if so, that alternate methods will be required to jack the bridge. Related to this, can beams be jacked individually to replace bearings?
Answer: DB Team may evaluate soil bearing properties to determine if a higher bearing pressure is allowable. DB Team may also propose alternative jacking methods (i.e. jack via a new or temporary diaphragm, or jack directly to the girder via a bracket attached to the face of the abutment). DB team may evaluate jacking beams individually, but will be responsible for repairing any cracking that may occur as a result of not jacking all beams together.

Question: Per Section 3.11.2 of the RFP, Any ATC that varies from the BTC construction staging plans must be accompanied by a traffic analysis model. A previous question, asked on 2/21/20, responded to on 2/27/20 states that the DB team shall provide a VISSIM model for each of their phases and show that peak hour traffic conditions are comparable to existing conditions. BTC staging VISSIM models will not be provided by RIDOT during the proposal phase. This differs from Section 3.11.2 which requires modeling only of phasing that is changing the BTC conditions. Please clarify whether models are required to be provided by the DB team to analyze construction phase traffic conditions of stages that follow exactly or are not materially different from the BTC staging (same or better lane count, merge, and weave lengths for all movements). If modeling of BTC phasing condition is not required for proposal, please clarify which changes would trigger a requirement to provide this modelling. It is assumed that post award full staging analysis will be required even if BTC phasing is used.
Answer: The DB team shall provide a VISSIM model for each of their phases that are materially different from the BTC (lane counts, merge and weave lengths for all movements) to show that peak hour traffic conditions are comparable to existing conditions. If the results are not comparable to existing conditions, the DB team shall provide mitigation to minimize impacts. The DB teams shall include mitigation along alternate routes to accommodate the projected increase in traffic along these alternate routes. DB teams will be scored on their ability to minimize and mitigate traffic impacts on the mainline and local roadways.

Question: Compensation for contaminated material is covered by RFP Part 2, Section 4.5.8 and also Job Specific Specification 202.9901. Does the job specific specification govern over RFP Part 2? Please confirm that the D/B proposers are to carry costs for the following in the lump sum bid: labor, materials, tools and equipment, excavation, loading, handling, hauling, stockpiling, polyethylene, dust/odor control, soil classification, segregation, soil characterization, health and safety plan, security, runoff protection, erosion control, decontamination, operation logs, submittals, installation and removal of construction entrances/stone stabilized pads, vehicle washing, street sweeping, and all other incidentals required to complete the work as described in the 202.9901, in the RAWP and SMP, and elsewhere as referenced in the Contract Documents, complete in place and accepted by the Engineer.
Answer: The job specifications under 202.9901 do not govern over Section 4.5.8 or vice versa. Section 4.5.8 indicates the requirements that the DB Entity needs to complete to be entitled to compensation by RIDOT. Management, transportation, and disposal of contaminated material performed in accordance with the goals and objectives of the CMMP and any state, federal, or local environmental approvals (e.g. RIDEM RAWP and SMP), laws, or regulations and approved by RIDOT as conforming to Section 4.5.8 shall be completed in accordance with 202.9901. The required CMMP may reference the previously RIDEM-approved RAWP and SMP.

Question: There is an existing soil stockpile on site beneath the existing NB Viaduct. Are there characterization data for this stockpile? Are any D/B proposer costs associated with the removal of this stockpile to be compensated from the $4 million bid allowance?
Answer: As summarized in the Remedial Action Closure Report for the Southbound portion of the Viaduct Project dated May 2018, in December 2016, RIDOT anticipated changes in the scope for the Viaduct Northbound project which would require a significant amount of fill material. Because of this anticipated change, VHB, on behalf of RIDOT, requested RIDEM permission to have excess Type 1 soils (i.e., soils that exceed R DEC but not I/C DEC) remain on the North infield area until the material can be used for filling purposes on the northbound project which was anticipated to begin in 2018. RIDEM approved the request in an email dated February 22, 2017. The soil stockpiled under the Viaduct overpass was estimated to be approximately 1,000 cubic yards at the time. No characterization data specific to the stockpile exists to VHBs knowledge, but it had previously been categorized as Type 1 and as suitable for site re-use or disposal in accordance with the RAWP. Management and/or disposal of these soils is to be compensated under this contract in the same manner as any other Type 1 soils.

Question: The RFP sections 3.16.4.1 and 3.16.4.2 call for cobra head luminaires on 40’ poles at the roadway and 30’ poles on the ramps. Section 3.16.9 says that “No alternatives to the materials listed above will be accepted.” However, the team has observed high mast poles in the area of the project. Are these to be demolished? Can they be reused with new luminaires? Should the masts and luminaires be replaced with new masts and LED luminaires?
Answer: The DB Team is required to demolish the existing high mast lighting as part of this project. Existing masts and luminaires shall be replaced with new poles (of variable height as required by DB Team’s lighting design) and LED luminaires.

Question: Will the same treatment requirements detailed in Question 2 (above) apply to the required retrofit of the existing STUs that treat runoff from outside the project limits as identified within Part 2 - Section 4.3.3 of the Request for Proposal? And will the area outside of the project limits that flows to the basins contribute to the treatment goal for the northbound project?
Answer: The DB Team shall explore retrofits to meet the RIDOT Linear Stormwater Manual treatment requirements (maintaining what was designed to handle the SB project's stormwater, and adding the required STUs to meet the LSM requirements for the NB project). The DB team needs to explore areas outside the project limits to achieve the treatment goals of this project. The basins needs to be repaired and retrofitted to the MEP as part of the consent decree and in order to meet the stormwater goals required in the Southbound viaduct Water Quality Certification. If however, the STUs are redesigned such that, additional water could be directed to the STUs from the northbound project or off-site, then credits toward the northbound goal for the project would be allowed for the additional stormwater.

Question: Will the project have to meet the treatment requirements of the RIDOT Linear Stormwater Manual fully, or to the maximum extent practicable? Since the confines of the project restrict the space required for conventional treatment outside the roadway surface, particularly areas outside of the Viaduct and Ramps Interchange, will RIDOT accept subsurface infiltration systems under the travel way as a practicable method of treating stormwater?
Answer: The DB Team shall explore and document opportunities to meet the treatment requirements of the RIDOT Stormwater Linear Manual. If the DB Team cannot meet the treatment requirements then the DB Team will need to document treatment to the maximum extent practicable. RIDOT will not accept a subsurface infiltration system under Interstate Route 95 and/or interchange ramp roadway. RIDOT will accept subsurface infiltration systems under local roadways, such as Park Street or Smith Street. Areas contributing to the NBC sewer system are not subject to the RIDOT Linear Stormwater Manual treatment goals. All other drainage areas leading to the Woonasquatucket and Moshassuck Rivers are subject to the requirements of the RIDOT Linear Stormwater Manual. Both of the aforementioned watersheds are impaired and will require stormwater treatment to the maximum extent practicable (MEP), including offsite opportunities.

Question: Will RIDOT please provide specific locations that need to be disconnected from the NBC sanitary system and replaced with a proposed new drainage system and outfall?
Answer: RIDOT cannot directly answer this question. The DB Team needs to identify what areas within the project limits contribute stormwater runoff to an existing combined sewer system and follow NBC’s permitting requirements for the quantity of stormwater that can/needs to be disconnected. Combined Sewer areas are not subject to the consent decree, however, they will likely be subject to the RIPDES regulations, which requires stormwater treatment. In some cases the combined sewer system where the connection is made may not be owned by NBC. However, that facility may be connected to the NBC system. The DB Team will need to present their findings to NBC as their rules and regulations state the following: “Article 4.4 of the NBC’s Rules & Regulations states that no person shall make any connection or shed any stormwater flows to the public sewer system unless the NBC determines that this connection is the only reasonable means available and this connection must also receive the NBC’s approval. This regulation states that the applicant must bear the cost of developing and submitting a SMP to the NBC.”

Question: In reference to question posted on 02/21/2020, we understand that the BTC construction-phase models will not be provided. In order to provide appropriate comparison to BTC construction-phase operations, it is requested that RIDOT please provide appropriate parameters that should be applied to the construction-phase VISSIM models, including specific model behaviors such as lane changing distances, driver behavior, speed distributions, gap acceptances, etc. The RIDOT traffic design manual does not show the average capacity for work zones that maintain the existing number of travel lanes, and therefore it is requested that RIDOT provide the assumed work zone capacity (pc/mi/ln) so that the construction phase model can be calibrated to correctly represent work zone conditions.
Answer: The capacity along I-95 Northbound between Broadway off-ramp and the Route 146 interchange varies due to the complex transportation infrastructure with closely spaced on- and off-ramps and the heavy weaving movements. Under existing conditions, the capacity (serviced volumes) varies between 1,500 and 1,900 pc/mi/ln. For analysis purposes, it is reasonable to assume that the average capacity could be reduced from 1,750 to 1,600 pc/mi/ln (approximately a 10% reduction) under various construction phases to account for the reduced speeds through the construction zone due to reduced shoulders, traffic control devices, and construction activities. Regarding the Vissim model parameters, there are no Vissim model parameters developed for construction phases; however, the DB team shall adjust the lane changing distances and speed distributions to reflect the traffic control setups under various construction phases. The results of the MOEs (queue and travel time) shall be compared to the existing conditions. It should be noted that there are existing pockets of congestions/bottleneck areas along I-95 Northbound upstream of the Providence Viaduct (I-195 interchange, Thurbers Avenue, Route 37-Route 10). It is critical to ensure that the traffic impacts associated with each construction phase does not extend to and exacerbate the existing congestion/bottleneck areas.

Question: Volume 3, Sheet 1 – Notes to Design Build Team states the teams should carry additional steel repairs in addition to areas shown to account for girder ends that exceed the limiting section loss after sandblasting. Note that Bridges 706 & 708 already indicate to carry additional steel repairs beyond what is shown. Since there is no way for the DB teams to determine how many additional steel repairs may be required after blasting please provide an assumed quantity of added repairs at each bridge location so that each DB entity is carrying the same quantities within their lump sum price. Additional repairs beyond these quantities could then be considered for additional compensation subject to negotiation.
Answer: There are 13 known repair locations identified in the Preservation Plans (8 detailed in the plans; 5 called out in notes). DB Teams are required to carry costs for 5 additional locations beyond these 13 identified to cover additional repairs that may be warranted after sandblasting if shear section losses exceed 10% and bearing section losses exceed 20%.

Question: 1. Part 2, PG 44, 3.13.7.3 second paragraph"...back of the existing sidewalk, there shall be a 25' wide level area at sidewalk grade beneath structures …" This requirement may dramatically affect the new I-95 and Exit 23 North abutment design and the slope pavement indicated for that area, as compared to the grading and slope pavers indicated in the BTC. Will this contract be required to modify the slope paving of the existing southbound I-95, north abutment, which has been recently constructed under a prior contract to conform with the 25’ level area behind the sidewalk on Promenade Street. Site observation in the area indicate this 25’ set-back requirement for a level area behind the sidewalk was NOT incorporated into the prior project. Please clarify the transition between this contract and the prior Southbound construction in the area of Promenade Street.
Answer: No modifications are required to the SB bridge slope paving to remain. For bidding purposes, DB Teams shall assume 2:1 slope transition from the SB slope paving limits, laterally transverse to the bridge. Final design coordination will be required with the City and WRWC.

Question: In the BTC plan set Volume 2 page 80 of Replacement of Smith St. bridge No. 701 and Park St. Retaining Walls Volume 2, note #4 states “All Permanent soil nails shall be located within the Rhode Island Department of transportation right of way” The BTC drawings show the soil nails extending past the RIDOT ROW. Is this note correct or is it meant to be within the City ROW? Will the DB Team be responsible to prepare the ROW plans and Plats for this work?
Answer: A SFL and SHL run along west side of Park Street from Promenade Street to just south of the Credit Union. The SHL cross Park Street and runs along the east side of Park Street from the Credit Union to Smith Street. The SHL runs along the east side of Park street north of Smith Street. The City owns from Promenade to just south of the Credit Union. The State owns from just south of the Credit Union to Orms Street.

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?
Answer: CB-3 Ramp was designed for 30 mph. The sight distance issue occurs on the 7% upgrade which has a needed stopping sight distance of 184’ (adjusted for grade). This could be met with restriping a 2’ right shoulder. CB-2 Ramp was designed for 30 mph and to follow the geometry of the existing CB ramp. The sight distance issue is located on the steep upgrade allowing for a sight distance of 184’. By moving the lane over to a 2’ shoulder on the right a sight distance of 180’ can be achieved. A design exception would be required for 180<184. DB-2 Ramp was designed for 30 mph. The sight distance issue occurs at the top of the ramp before the merge with CB-3 at the 250’ radius curve with barrier on the right. This occurs on the infill area and may be mitigated or at least improved upon by putting the barrier to the outside of the infill area and/or modifying striping. Ramp AC Ramp was designed for 30 mph. The only sight distance issue would be the guardrail protecting the abutment of Ramp CB-2. The BTC shows this guardrail running at the roadway edge. This issue could be mitigated by either flaring the guardrail closer to the abutment or continuing the barrier to tie into the abutment edge to protect with curb or just edge of pave at the edge of the roadway. Final approval of all required design exceptions will be the responsibility of the D/B team. Proposals that minimize or eliminate design exceptions will be looked upon favorably by the evaluation team. For bidding purposes, DB Teams shall assume that all design exceptions shown in the BTC will be accepted by RIDOT and FHWA. Approval of any additional design exceptions resulting from an alternative design (ATC) are at the DB Team's risk.

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.

Question: 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.

Question: RFP Part 2, Section 3.12.7 outlines minimum requirements for the DB Entity if pile foundation re-use is to be pursued as part of an ATC. The BTC plans show pile re-use at several substructure locations throughout the site. 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.
