Description:   REPLACE STEAM & CONDENSATE MAINS OVAL 1 & OUTLYING BUILDINGSTIERED EVALUATION OF OFFERSPROJECT NO. 542-18-104, SOLICITATION NO. 36C24422R0140AMENDMENT 0003VA Response to Contractor Questions from site visit on February 21, 2023Evaluation Factor: A. Proposed Team - Item j. Commissioning shall be removed from this evaluation factor.2nd site visit scheduled for March 30, 2023 at 10:00 AM, meeting at Coatesville VA Medical Center, Bldg 702nd round of Contractor questions due April 14, 2023VA response to 2nd round of Contractor questions on/or about April 28, 2023New Proposal due date May 12, 2023 by 4:30 PM, email to Contractor RFI Questions and VA Responses To evaluate successful completion is the VA requesting the submission of existing CPARS with the proposal? VA response: YesWill experience of sister companies/subsidiaries be evaluated and accepted for past performance projects? VA response: Only if the parent company is part of the team when executing the contract. Are the past performance projects of predecessor, sister companies, subcontractors, teaming partners, etc. weighted any differently than those of the prime? VA response: NoDo resumes count towards the 25-page limit for Section 1 VA response: No. 25 page limit is only related to the narrative in section 1.The SOW indicated 550 days for the POP.- Is it the VA intent to suspend the contract during winter shutdowns so the POP will only count towards months where work is allowed?VA response: No. The existing steam distribution must remain in operation until the new system is ready for full activation and switch-over. Switch-over should not occur during the winter. Nothing prevents the contractor from working during the winter other than potentials to freeze exposed underground utilities, which must be prevented. The contractor should submit a plan addressing this issue.- If no to above, please consider that with the bid due late March and pricing is to be held for 120 days, award could be made 1st of July.? By the time initial submittals and plans are made, it would be Sept and the contractor would not be able to mobilize due to shutdown for winter.? Therefore, actual work would not start until April 1 or 9 months of no work.? We would lose 270 days of the 550 POP before we break ground.? We would essentially only have one working season to complete all work with the last 2-3 months of the POP during the next winter shutdown period. Please confirm if this is the expectation. VA response: That is the expectation. It is expected that the 550 days will be met unless a valid reason to deviate is presented.- Please confirm if the proposed POP can be negotiable due to the lead time on materials and coordination that is required on this project?VA response: No. Lead time should be incorporated into the proposed schedule. If changes occur, considerations can be made.Section 01 00 00 -2 indicates the project requires that heat be maintained in all buildings during the heating season. Is it the VA s intention that the contractor provide temporary heat for the buildings when the campus wide steam is not available? VA response: Yes, steam should always be available to the buildings. The use is for both cold weather heating, as well as domestic hot water year-round, other than 8-hour (approximate) shutdowns.Section 01 00 00 22 indicates the contractor must provide photographic documentation of construction progress. To what extent must the contractor provide these photos? Will they be reviewed at the weekly meetings or submitted as part of the contract documentation. VA response: Application of the documentation will be at the COR s discretion.Changes to the construction schedule. The language indicates the contractor has a responsibility for completion. The VA indicates that the contractor should remedy any construction delays with manpower, increase in working hours per day or rescheduling the work in conformance with specification requirements. The majority of this work is out of doors, will the VA entertain adding additional time for delays associated with weather? VA response: Yes Will additional time be provided if sufficient cause for delay is presented to the government?VA response: YesWhat are the liquidated damages per day if the project runs past the POP? VA response: Actual damages will/shall be assessed if contractor goes beyond completion date.Will the VA hold the selected QCM to the experience matrix they have provided in the specifications? VA response: YesSection 23 22 13 17 Can the VA clarify the requirement for radiographic verification of the welds for this project? VA response: Will be done per specifications. Section 01 91 00 35 Indicates the contractor must return after one year to inspect the installed piping. One of these requirements is that the contractor must provide a commercial grade sUAS or drone platform equipped with a 3-axis stabilized high resolution radiometric thermal camera. The camera must utilize a long wave microbolometer detector with a resolution of 640x512 and a frame rate of 30 hz. Is this correct? VA response: YesAdditionally, section 01 91 00 35 requires that the company providing the commercial drone have an additional $3,000,000.00 in liability insurance. Is this correct? VA response: YesSection 02 21 13 Requires that the contractor verify the drawings 100% and once the contractor verifies the drawings they are responsible for all changes in the design. Is this correct?VA response: No. Section 01 00 00, Article 1.7 Alterations and Article 1.10 Restoration address differing site conditions. Article 1.7, Paragraphs A and B in this project deal primarily with site features, including sidewalks, benches, drainage features, plantings, any appurtenances, etc. Section 02 21 13 does not apply to this project and will be deleted.Section 01 00 00 2 Indicates that the VA previously awarded a tree management and sidewalks contract. To what extent must the contractor protect or restore this work? Can the government provide the extent of this previous contract?VA response: Restore to match existing.

Is the reference to the stamp an indication the contractor must hire a structural engineer to review the previously engineered drawings? Why can the contractor not use the designers stamped engineered drawings as the submtted structural material?VA response: The contractor s stamp of approval is a mark indicating that the GC received, reviewed, coordianted, and approved the subcontractor s shop drawings. A PE stamp is not required for shop drawings unless noted in General Notes or Specifications.Item #15 on S-001 again indicates the contractor must employ a structural engineer when altering existing structures is this correct? VA response: The penetrations and alterations to the existing structures as shown do not require a structural engineer.

VA response: Refer to Notes on Drawings S-001 and SS001 as well as Specifications.Is the contractor required to use the below sleeve for penetrations? VA response: Yes, sleeves and seals are the basis of design. Drawing MP 105 indicates valves for medium pressure steam and pumped condensate are to be a ball valve for 4 and smaller and a triple offset butterfly for 6 and larger, what should the contractor use for the 5 MPS pipe in the basement of building #16?
