Q: Does the scope of work include structural assessment and repair of plywood sheathing (or possible lack of) beneath the roofing material or installation of new structural sheathing if it doesn’t exist?
A: Preliminary investigation indicates there are sections of roof where no plywood sheathing is currently installed, and we would expect that the completed roofing design and installation would specify replacement of damaged sections as needed, as well as the addition of new plywood sheathing in places where none currently exists. The Architecture and Engineering phase of the project as defined in the current RFP would not seem to be greatly affected by a lack of information about the presence or condition of plywood sheathing.
Q: Please confirm that scope item #1 refers only to roof framing elements in the horizontal plane (i.e. no vertical walls, with the exception of the balcony structure).
A: The plywood sheathing requirement will apply only to the roof and balcony surfaces and not the adjacent vertical walls.
Q: Regarding the paragraph “Existing Conditions”: We have concerns about identifying possible structural repair work related to the roofs. Is an Exploratory Phase allowable to assess the conditions related to Item #1 of the scope of work “Repair or replacement as needed of underlying wood frame elements.”
A: Please feel free to propose an Exploratory Phase within the timeline indicated for completion of plans and drawings.
Q: Please confirm as-built drawings of the Home, Workshop 1, Workshop 2, and Guest House are available.
A: The original construction of these four buildings took place in phases over a 50-year period. We are not aware of any blue prints originating at the time of first construction, however, these buildings were documented in preparation for relocation and the resulting drawings would be available in hardcopy form for use or reference in the current project. Please note that existing drawings and relocation documents were cataloged at the time of the Historic Structures Report, which provides descriptions and links to these materials.
Q: Are there existing storm drains on site that new or replacement rain gutters and downspouts can tie into? If not, is Scope Item #7 work to include Civil Engineering to address stormwater drainage/ retention?
A: Several non-roof drains exist on the property, with some documentation likely to have been developed at the time of relocation. While plans produced during the Architecture and Engineering phase described in the current RFP may need to specify materials and engineered solutions for draining water from the roof surface, we do not currently expect the plans to address facilities for drainage that may be located elsewhere on the on the property. For the purposes of bidding this RFP, applicants may assume that water from the roof will drain to the ground-level, where it may enter drains unrelated to the roof. If roof evacuation water volumes are expected to overwhelm non-roof drainage capacity, please note this observation in your RFP, with proposed mitigation strategy.
Q: Is a Cost Estimate required at 80% and/or 100% Construction Documents?
A: National Park Service must review and approve plans at 80% and 100% of completion, and prior to bidding by roofing contractors. Architecture and Engineering RFP bidders are expected to provide design, material and construction experience sufficient to anticipate with reasonable confidence that designed solutions are attainable within the proposed construction budget. Contractual exceptions or limitations should be noted in the RFP response.
Q: Is the grant amount only for construction or does it also include soft costs for design fees?
A:This Phase 1 RFP covers architecture design, engineering and documentation for review and approval by National Park Service, suitable for use in the preparation and circulation of a phase 2 RFP seeking bids from qualified roofing construction vendors. The total Save America’s Treasures grant amount will apply to design and engineering services, including production of plans subject to review and approval by National Park Service, and subsequent onsite repair and replacement of the roofing, balcony, skylights and other details described in the RFP.
Q: Should a cost estimate be included in the proposal?
A: Architecture and Engineering Services proposals need only to bid costs for Phase 1 services described in the RFP. It is not necessary to estimate total roof repair and replacement costs at this time. Please note that Architecture and Engineering Services bidders are expected to provide design, material and construction experience sufficient to anticipate with reasonable confidence that designed solutions are attainable within the proposed construction budget. Contractual exceptions or limitations should be noted in the RFP response.
Q: How large are the roof areas that require re-roofing, in square footage?
A; This is a comprehensive roof repair and replacement project. Existing roof area has been estimated at approximately 8,400 sq. ft.
Q: We plan to include a structural consultant to advise on structural wood damage and possible replacement. Do you anticipate a need for other engineering consultants?
A: Project will involve repair or replacement of posts, beams, rafters and other visible elements of the roof structure, sub-structure and surfaces, as well as unseen elements revealed following removal of existing roofing materials and flashing. Project also entails replacement and possible fabrication of gutters, downspouts, drainage solutions, skylights and possible metal capping of damaged rafter tails. Water removal may require consideration of estimated water flows and design of efficient systems to carry rainfall from the roof via gutters and downspouts. Skylights and federal energy compliance requirements regarding heat, sunlight and properties of insulation, which may require some calculation of thermal loads and efficiencies.
Q: Addenda section: A date for publishing addenda is noted as March 23rd, 2020. Please confirm the date addenda will be posted to the Maloof RFP website.
A: Responses to questions will be available February 23, 2022.
Q: Proposal Form and Format section: In this section, the time that Proposals are due is noted as 10:00 a.m., while on the first page of the RFP, the time due is noted as 4:00 p.m. on Monday, February 28. Please confirm the correct time.
A: Proposals are due on Monday, February 28 at 4:00 p.m.
Q: Payments section: This section notes that “a single payment will be made to the vendor.” We respectfully request that the Maloof Foundation consider revising that to allow the selected vendor to invoice Maloof monthly based upon effort expended, within the proposed fee.
A: Terms of payment are negotiable. Please include your suggested terms or limitations in your RFP response.
Q: Liquidated Damages section: Liquidated damages are part of contractor agreements, but rarely part of professional services agreements. We respectfully request that the Maloof Foundation consider removing this section of the RFP.
A: We are glad to consider removing the liquidated damages clause as it applies to professional services in support of the Roof Repair and Replacement project. Further discussion and finalization of these details will be handled as part of our contracting process.
