Question: A note was added to CS-7 that states Bridge 633 steel repairs shall be completed within 60 days of NTP. The NTP will probably be issued at the end of January. The blasting and painting of the existing steel would have to be completed in the winter which will make it tough. Can the steel repairs be completed in the spring when the temperatures are warmer for the blasting and painting.
Answer: Due to recent bridge inspections, the steel repairs need to be completed within the 60 days of NTP. Application of the intermediate and top coat can be pushed until warmer weather conditions.

Question: For the micropiles at bridges 062801 and 062901, we are dealing with low headroom conditions requiring drilling with 5’ lengths of casing. Looking at the detail on sheet 19 of 85 (Volume 5), there is a note #5 that requires no splicing of the micropile casing or core bar in the top 15’ of the pile. Can this note be modified to allow no splices within the top 5’ of the pile?
Answer: We believe there is sufficient headroom for a 15-ft. section, however, if the final micropile design can demonstrate that the moment demand in the pile can be met with a reduced moment capacity, due to thread joints within the top 15-ft. of casing, then splicing of the casing within the top 15-ft. will be acceptable. Splicing of the core bar within the top 15-ft. is acceptable

Question: We assume the global “design” of the precast slabs is provided in the contract plans and specifications. We assume the 8-inch slab thickness shown is adequate for the ADT Average Daily Traffic and truck traffic, design speed and other necessary parameters. We assume that Concrete-High Performance Class XX, ¾” (f’c=4,000 psi) is adequate for the 8-inch design thickness and load conditions. We assume the existing Gravel Borrow subbase and existing drainage system will provide a satisfactory foundation for this pavement section. We assume the global precast pavement slab design is the responsibility of the Design Engineer of Record for the project – Trans Systems or RIDOT, not the Contractor or precaster. Are these assumptions correct?
Answer: Assumptions are the responsibility of the contractor. As previously noted, and as shown in the plans and specifications, the contractor is responsible for the design of the precast slabs and for the installation details of the slabs, including preparation of subgrade, to provide a suitable structure. The design submittal and all assumptions will be reviewed by the designer of record prior to precasting the slabs.

Question: CS page C-6 under Section 3. Utility and Municipal Notification and Coordination under Approved Subcontractors lists approved contractors for completing the installation of underground conduits and manholes for NGrid Electric. It further states that all work performed on these facilities must be complete by a subcontractor from this listing. Two issues: 1) This list is not current. Please provide the current list. 2) NGrid Electric allows other contractors (not on this list) to complete underground primary duct systems and manholes from riser to riser that does not involve any existing live underground electric. This is the case on several current ongoing RIDOT projects with similar work. This specific issue has been discussed with NGrid in the recent past and they only require an NGrid approved contractor if the work is on existing live electric. Please consider revising the language in the CS pages to be in accordance with NGrid current practice.
Answer: The information contained within the CS pages has been verified. The contractor should use the list included in these pages.

Question: In response to the localized painting of existing steel - you have indicated that "if any beam is repaired and the plans don specify cleaning and painting, the cost of cleaning and painting the repaired beam end shall be paid under the steel repair pay item."

Question: Both JS Code 800.9930 and the the project plans volume 5 note a minimum low chord elevation of 24.4 for temporary work platforms. The job specific spec further notes that if the Contractor's means and methods do not meet all requirements established in regulatory permits for the project, he shall allot time to obtain revised permits. The RIDEM insignificant alterations permit is the only permit in the bid documents and does not mention anything about the Pawtuxet River, Pawtuxet River Bridges or elevation 24.4. What is the significance of a low chord elevation no lower than 24.4 for the depicted work platforms and why is this being regulated? Please provide any permit documents that may have been inadvertently left out of the bid documents.
Answer: The RIDEM permit was approved based on all information and dimensions provided in the contract documents, including the minimum low chord elevation. This low chord was established to keep all work above the 100-year flood elevation. The permit is issued based upon this assumption.

Question: Regarding JS 936.9902 - Force Account Bank - Unexpected Amtrak Downtime. 1. The spec allows for payment of rental and leased equipment downtime, but not owned equipment. Request this be revisited. Owned equipment downtime has value, just as rented/leased equipment. Many construction companies also own equipment companies that lease the equipment to the construction company. Therefore, most construction equipment is technically leased or rented to the construction company anyway. 2. The specification states that downtime will be paid on force account for Amtrak cancellations of scheduled track outages after 9pm. It further clarifies that this is related to the 4 hour window that is actually a 3 hour work window due to de-energizing and re-energizing wires. Please clarify that the force account is to pay for any shortage of planned and properly scheduled outages, not just a cancellation after 9pm. 3. How is down time paid for scheduled foul time work, track out of service without planned OCS outages, lack of Amtrak flagmen, track foremen or other lost work time for planned and coordinated Amtrak work where Amtrak is solely responsible (either directly or indirectly) for the downtime. 4. Please provide all train schedules for this section of railroad. 5. Is coordination with any other railroad besides Amtrak required for this work?
Answer: This specification will be revised by a forthcoming addendum. Anticipated Amtrak schedules are available at Amtrak's website. No other railroad coordination is required other than through Amtrak.
