27) Please confirm uninterrupted access to Adams Street (running parallel to wharf / perpendicular to the travel lift path) during construction does not need to be maintained?

RESPONSE: Adams Street is a primary travel route. Interruptions shall be handled in accordance with Specification 01500, Paragraph 1.9 Interruption of Vehicular Traffic.

28) Please confirm uninterrupted access to access to Building 32, 32A, and 90 during construction does not need to be maintained?

RESPONSE: Access to Buildings 32, 32A, and 90 shall be maintained in accordance with

Specification 01110, Paragraph 1.1 and paragraph 1.6.3.

29) Base vs Option 2 Scope Conflict. The Price Proposal Form and Section 1800 1.1 states Option 2 is “to construct Bay 1 FRC maintenance facility heating system, through make up air units, add dehumidification, and add industrial dust collection.” Specification section 1800 1.12.1.1 Base Bid states “For heating, provide hot water unit heaters to maintain HVAC design condition interiors” and

1800 1.12.1.2 OPTION 2 states “for Bay 1 only, provide mechanical equipment to allow Abrasive Grit

Blasting and Painting Operations for FRC RDAP”. The Price Proposal Form and 1800 1.1 conflict with 1800 1.12..1, 1.10.1 and 1.11.1 with regards to where Bay 1 heating scope/cost is to be provided – in the Base Bid Price or in bid Option Item 2? Please clarify.

RESPONSE: See MP-101, HVAC Design Conditions (Descriptions) and MP-104 One Line

Diagrams for details. There are two types of heating systems.

BASE BID – Basic Heat (HW Unit Heaters) and General Exhaust for Bay #1. This is to prevent freezing conditions inside Bay #1 during winter periods.

Option 1 - Basic Heat (HW Unit Heaters) and General Exhaust for Bay #2. This is to prevent freezing conditions inside Bay #2 during winter periods.

Option 2 – BASE BID + Dehumidification, dual exhaust plenum, Make Up Air Heat. This allows painting and grit blasting to occur in Bay #1 ONLY. If Option 2 is to be awarded, the user will have heat during general maintenance activities via hot water heaters AND be able to paint and grit blast via the 100% vertical make up heaters.

30) Please clarify the intent for R-30 roof insulation and R-13 wall insulation requirements noted in section

1.7.4.1.10 Building Insulation. These values do not meet the requirements set in Section 1.7.1.3.1

Building Insulation that instructs the D/B team to determine the requirements based on ASHRAE

189.1. Is 1.7.1.3.1 just for a conventional building and not for a pre-engineered building?

31) Please confirm all cost to enclose Boat Work Bay 2 including foundation work is to be included in Bid

Option 1?

32) Construction of the new piers is expected to require a major project review for the Joint Permit

Application (JPA). JPA review/approval timeline for this project will take approximately 15 to 18 months. Is the Government aware of permitting allowances for the Yard that will allow the JPA review/approval process to be reduced? Please provide along with an expected expedited procurement period.

RESPONSE: No, the government is not aware of any special permitting allowances held by the

Yard. The contractor must follow Section 1800 - 1.18 as it relates to permitting and is encouraged to develop permit applications early in the design build process. The government concurs that obtaining certain permits could be a lengthy process.

33) Can the Government confirm limits of work at the west wharf may extend from station 0+00 to station

3+00?

RESPONSE: Confirmed. While the travel lift finger piers site shall is restricted, utility connection work (et al) may extend outside of the Stations 0+00 and Station 3+00.

34) Please confirm RFP specification section 01800, 1.8.4.4 Cast-in-Place Concrete is for project cast-in-place slabs including the travel way, transfer slab, and Boat Work Bay slabs with the exception of the mechanical room. We assume the mechanical room slab can be non-marine mix concrete with uncoated reinforcing.

35) Please confirm RFP specification section 01800, 1.8.4.4 Cast-in-Place Concrete that landside of the bulkhead foundations below the cast-in-place slabs do not require marine mix and epoxy coated reinforcing.

36) After award, if the contractor's site investigations and site borings find soil conditions different than the

RFP site borings, please confirm any required scope changes will be handled as a differing site condition.

RESPONSE: As stated within Specification 01800-1.5.2, ‘The Design-Builder shall bear all costs of the actual foundation provided, except under circumstances where adjustments in contract award price may be made under the provisions of Contract Clause FAR 52.236-2, "Differing Site

Conditions".

37) We do not see a need for enclosed Boat Work Bay floor drains except for the possibility for seawater coming off boat hulls when moved into the enclosed bays as indicated in RFP specification section

01800, 1.8.4.6. Please confirm if floor drains are required for enclosed boat work bays for any of the pricing - base or options? Please confirm if the open Bay 2 in the base price requires floor drains?

RESPONSE: Floor drains are not required in the boat bays. However, floor drains are required in the Mechanical room per RFP 1800 Section 1.11.2.4.

38) Confirm that floor drains are not required for Option 2, Blasting and Painting operations in Bay 1?

39) Please clarify the compressed air requirements for the new FRC RDAP building processes. Section

01800-1.11.7.1.1 of the RFP states “The building compressed air system shall be sized to accommodate the number of connections as required, with a maximum total pressure drop of 5 psi.” Additionally, construction note 1 on RFP drawing MP-102 indicates minimum air receiver size of 400 gallons. Please provide the total number of connections required for base bid and bid option 1, SCFM for each connection, and operating pressure to properly size the compressed air distribution and confirm air receiver tank size.

RESPONSE: See Amendment.

Per sheet MP-101, “Compressed Air Utility Mound” piping shall be provided to support operations on 3 levels (Lower Deck, Middle Deck, and Upper Deck).

The CG Yard has shop supplied manifolds and cabling that will be connected to each level.

Estimate 10 operators working simultaneously at one time. The Coast Guard connects manifolds to each level. Hoses are connected the manifolds that are connected to blast pots. The RDAP

Building will require five (5) blast pots (8/6 ton). Each blast pot will need to maintain 700 CFM.

Blast Pots are provided by the Coast Guard. The operating pressure needs to be at least 130

PSIG.

The Coast Guard plans to rent supplemental Air Compressors to meet the air demands of the

FRC RDAP Building. The Compressed Air One Line Diagram Final design shall incorporate a suitable connection point for this to occur at the FRC RDAP building. For bidding purposes and determining the connection point size, assume the Coast Guard will rent (2) 1600 CFM Air compressors with built in moisture separators along with external moisture separators due to the amount condensation that builds up in the air lines.

Summary

For bidding purposes, SCFM per blast pot – 700 SCFM (Grit Blasting)

5 Blast pots required for the project. Therefore, total capacity needed = 5 * 700 = 3,500 SCFM

Operating pressure (for proper operation) – 130 PSI

Coordinate exact design requirements with end user prior to final design.

40) Please confirm that finger pier accessories such as safety ladder, rails, life ring, nav light, fenders, pile dolphins, mooring bits/bollards/cleats are all to be furnished and installed by the Contractor.

41) The RFP specification mentions the Government's preference in several locations. Please confirm that when "preference" is used it is not a Government prescriptive direction and it allows the DOR to design at its own discretion.

RESPONSE: Preference or preferences appears three times within the RFP.

In Specification 01800, Paragraph 1.8.4.6; ‘DOR shall utilize the most corrosion‐ resistant metal materials for building components and assemblies and shall include, but not be limited to (in descending order of preference), anodized aluminum, stainless steel, and hot‐dipped galvanized steel.’ The DOR is provided with design discretion.

In Appendix D-Basis of Design Narrative, ‘e. Documentation of customer’s preference for the HVAC control system’. The requirement is to document the customer preference.’

In Specification 01800, Paragraph 1.18.7, ‘The Coast Guard’s order of mitigation preferences are to first offer features that are already part of the project, followed by payment into available mitigation funds, followed lastly by additional project mitigating features acceptable to regulatory agency.’ The DOR is provided with design discretion.

42) Please confirm that this project / bid should not include any scope / pricing for the future intentions to perform hydroblasting. If we are to include, please provide a detailed scope including what infrastructure we are to include for future hydroblast capabilities such as water supply, drainage and treatment requirements, separation and storage tanks, etc.

RESPONSE: Confirmed. No bid option or pricing is required to accommodate the future hydroblasting. See Amendments for Work Bay sump pit.

43) Construction of the new piers is expected to require a major project review for the Joint Permit

Application (JPA). JPA review/approval timeline for this project could take approximately 18 months to design, review, and procure. The current RFP performance period of 598 calendar days is not sufficient to incorporate the JPA procurement. Based upon our initial schedule analysis we are recommending an additional 15 months be added to the performance period making the total performance period 1,054 calendar days. Please consider revising the Contract Performance Period to

1,054 calendar days to allow proper time for the project.

RESPONSE: See Amendments. We concur that in-water work cannot commence until a Joint

Permit is issued by USACE/Maryland DEP. The government has reevaluated the contract performance period. A change the performance period from 598 calendar days to 705 calendar days is validated.

The Contractor should prioritize the completion of permit application preparation and submittal for in-water work in their project schedule. Additionally, the contractor should evaluate the project’s sequencing as in-water work may have to occur later in their project schedule depending on how long the permitting process takes.

44) Please confirm the ‘Unobstructed Emergency Egress Aisle’ is the code defined egress path, and any area between structural elements would be in addition to the space defined on sheet A-101? Based on our understanding of the RFP and the code requirements, we anticipate the Boat Work Bay needing to be roughly 3 feet wider than shown in the RFP drawings unless the 7'-0" clear working space on either side of the FRC vessel can be reduced. Can we reduce the 7 foot clear working space to maintain the

RFP building width or should be increase the width of the building? This number would apply to

Option Item 1 for Boat Bay 2 as well.

RESPONSE: RFP drawings are conceptual not construction. Proposed design solution should maintain code required egress minimums and 7’-0” work space. If contractor has determined that building needs to be wider, then that is the solution that needs to be presented and priced.

45) Due to the extensive process drainage / cleaning of heavy metals and required separation from the storm water system resulting from blasting process, please confirm that no blasting operations will occur outside of Bay 1? Please provide if any required floor drains are required specifically for capturing and cleaning of heavy metals from the blasting operations including stormwater treatment, and stormwater / process water separation, and process water storage for pumping by CG Yard operations.

RESPONSE: Any process water generated will be captured inside the building. The project does not include any process water treatment, and process water will not be discharged to either the

Yard’s sanitary sewer or the stormwater system.

The Yard will be responsible for any pumping/treatment/disposal of process water contained by the project’s required collection/containment. Bay floors shall be designed to allow for containment of process waters. Bay floor drains or discharge piping shall not be permitted. Bay floor trenches, if utilized, shall be imperious and sealed so that there are no leaks.

The storm water will not flow across surfaces under the roof’s cover and therefore will not contact any process water. Storm water shall be treated in a typical manner in that any required temporary or permanent stormwater best management practices will meet all federal and state stormwater control requirements.

46) Specification section 01800, 1.11.2.4 Floor Drains for the Boat Work Bay states for information see

01110, 1.1.1 Overview. This section does not specify where floor drains are required in the Boat Work

Bay. Please confirm floor drains are not required in the Boat Work Bay 1 and 2 areas due to the extent of any runoff generated from cleaning heavy metals from the blasting operations that will require stormwater treatment, and stormwater / process water separation, and process water storage for pumping by CG Yard operations.

RESPONSE: Floor drains are not required. See Amendments for Work Bay sump pit.

47) Can the Government confirm that all CG Yard materials including fixtures, furniture, and equipment will be removed from Building 47 and Building 148 prior to the start of Construction?

RESPONSE: Buildings 47 and 148 shall include all permanently mounted fixtures and equipment

(i.e., lighting). The buildings shall be removed of all loose furniture (i.e. floor shelves).

48) Sheet G002 indicates an area for Contractor Trailer and Laydown Area in Lot 19 along the west wharf.

The area indicated appears to extend beyond the limits and Station 3+00 indicated on sheet C101. Can the Government please clarify the limits of the Contractor Trailer and Laydown Area to the west of

Station 3+00?

RESPONSE: Refer to Specification 01110, Paragraph 1.5.1 that describes the Contractor’s

Trailer and Laydown Areas.

49) Does the Contractor need to maintain access / availability of utilities to the ship-to-shore ties along the west wharf with in the Contractor Trailer and Laydown Area? Is the Contractor permitted to connect to the ship-to-shore utilities for temporary construction use?

RESPONSE: Refer to Specification 01110, Paragraph 1.5.1.2 for maintenance of access to ship-to-shore ties. Yes, the Contractor permitted to connect to the ship-to-shore utilities for temporary construction use.

50) Can the Government please confirm if there are any special design loads hanging from the building structure to perform work on the FRC vessels and if so please provide loads and location information?

RESPONSE: There are no special design loads hanging from the building structure to perform work on the FRC beyond what has been provided within the RFP.

51) Can the Government please confirm if there are any special design loads that need to be accounted for on either the building structure or concrete slab to support the equipment for welding, blasting, and painting operations and if so please provide loads and location information?

RESPONSE: There are no special design loads that need to be accounted for on either the building structure or concrete slab to support the equipment for welding, blasting, and painting operations beyond what has been provided within the RFP.

52) The ISCS contains the only reference to provide epoxy coated concrete in the Boat Work Bay. Please advise if the reference to epoxy coated is for a paint on epoxy coating finish or troweled on mortar or resinous epoxy coated finish? Please provide a basis of design or specification criteria as there is a vast range in level/types of epoxy flooring finishes.

RESPONSE: For this application, an epoxy paint is acceptable.
