Seismic Bracing Requirements for Fire Suppression Piping RFP Specification 21 13 13.00 10 paragraph

3.4.1, RFP

Drawing S-001

RFP Drawing S-001 indicates the seismic design category is B which would not normally require seismic bracing for fire suppression piping per ASCE 7 Paragraph 13.1.4. RFP Specification 21 13

13.00 10 (Wet Pipe) 3.4.1 requires seismic bracing but the high expansion foam spec (21 13 20.00 30) does not require seismic bracing. Also, Spec 21 13

13.00 10 requires seismic bracing design to comply with UFC 3-310-04. But, UFC 3-310-04 paragraph B-3.2.4 implies that piping constructed in accordance with NFPA 13 is not within the purview of UFC 3-310-04. Please confirm which systems require seismic bracing and explain intent of UFC 3- 310-04 reference as it relates to fire suppression system seismic bracing design.

The wet pipe system seismic requirements shall comply with Category B requirements and NFPA 13. The foam system piping shall comply with General Note #6 on Sheet FX-104 and all foam piping shall be seismically braced (regardless of the seismic design category). The intent of UFC 3-310-04 is for the mounting of the generators per ETL 15-01-03 Section 9.7.2 and not the system piping.

AFCEC

Guidance Criteria RFP Drawing Sheet

GI001.

RFP Drawing Sheet GI001 lists "AFCEC Guidance for Addressing Hangar Fire Suppression Requirements - Criteria Changes" as an applicable criteria. The only version of this document we have is undated and not titled to match sheet GI001 and therefore I am not sure if it is the identical criteria.

Please provide the specific version of this AFCEC Guidance document with which our design is required to comply.

The A/E has been provided the same untitled document from the Air Force and the Air National Guard and they are not dated nor titled. The documents will be provided.

RFP Specification 21 90 00 paragraph 1.1.c and 1.4

RFP specification section 21 90 00 paragraph 1.4 includes the requirement to "engage commissioning service personnel that specialize in the types of inspections and tests to be performed." But the subsequent paragraph suggests the project FPE is responsible for commissioning. The language "commissioning service personnel" sounds like something different than the project FPE, but I do not believe this was the intent. Please confirm the intent of the RFP is for the FPE described in the fire protection system sections to also serve as the commissioning agent as defined by 21 90 00, assuming they have experience performing acceptance testing, integrated testing, and commissioning of the stated systems.

It is not the intent that the Commissioning Agent(s) be an FPE. For example, some foam systems may require a Commissioning Agent to be brought in from the foam system manufacturer to provide all commissioning, testing, balancing, ect. The Det-Tronics releasing system could also require a factory commissioning agent if the installing contractor does not have Factory Certifications to provide final testing. These Commissioning Agents should coordinate with the FPE to devlop the testing plans and schedule. However, if the FPE has experience in the integrated testing of all these systems, they may also serve as the Commissioning Agent.

11/17/2016 35 RFI Cut Off Date

Section 3.3 of the RFP states that "all questions and requests for information (RFI) must be received NOT LATER THAN the fifth working day prior to closing…".

Can the government please provide specific instructions for the electronic submission of bids?

Answered RFI 12

11/17/2016 37 Requests for Work on Fridays

It was discussed at the pre-bid site meeting that contractors could put in a request to perform work on Fridays. Can a "blanket" request be submitted to request permission to work all Fridays for the duration of the contract (provided that government inspections are not scheduled to take place on Fridays)?

NO, insulation policy is that weekend Entry Access Lists are provided weekly.

However, sheet ES-100 states that the contractor is to provide this transformer. Is this an existing transformer that is to be relocated from its current location? If so, where is the transformer currently?

The transformer to be installed on the NW corner of the facility is new and is to be provided by the contractor.

Structural Steel for Elevator 2 @ Lean- To A Drawing Sheets S-400, S- 401 & S-500

The structural drawings (sheet S-400 in particular) indicate that no new structural steel needs to be installed or existing steel removed for the installation of Elevator 2 at Lean-To A.

All structural steel in the Elevator 2 drawings is shown as existing with no notes regarding removal. Is this accurate?

The Elevator 2 shaft in Leanto A is a new, structurally independent CMU structure located inside the existing parachute tower. The existing steel tower structure will remain in place and does not require modification as part of this project.

Contractor FPE & Fire Protection System Commissioning Specification Section 21 90 00

Paragraph 1.4 of spec section 21 90 00 states that the contractor's FPE is to be responsible for the design and commissioning of the fire protection system (to include fire alarm, mass notification, fire sprinkler, fire pumps, and foam systems). Typically, fire alarm & mass notification drawings are prepared by a fire alarm contractor (usually a NICET III technician) and fire suppression (sprinkler & foam systems) are designed by a fire suppression contractor. Is the governments intent that the prime contractor employ/hire a single fire protection engineer to review/approve/stamp the designs developed by these parties and perform commissioning on all of the fire protection systems?

The fire protection systems for the hangar and building protects high value asset and require the full oversight of an FPE. NICET certification or years experience is not a substitute for the FPE qualification. As clearly indicated in the specifications, the prime contractor shall hire an FPE. This FPE shall develop and design the fire protection systems documents with the fire alarm, MNS, foam, and sprinkler system contractors. The final drawings shall be signed and sealed by the FPE. The FPE shall have full control and input in the systems design and commissioning.

Hazardous Material Abatement Drawing Sheets G- 002, H-121, H- 122, H-131, H-132

The sheet index on sheet G-002 states that sheets H-121 & 122 pertain to the abatement of lead based paint (LBP) and sheets H-131 & 132 pertain to the abatement of asbestos.

However, in reviewing these sheets, all four (4) sheets are labeled "LBP Diagram", but all contain notes about asbestos remediation (H-131 is a duplicate of H-121, and H-132 is a duplicate of H-122… all of which only contain notes regarding asbestos abatement. Can the government please advise if these sheets are supposed to be duplicates?

The noted drawing sheets have been corrected. Refer to the attached documents.

11/17/2016 48 Fire Pump House Foundation

Is a slab and/or foundation required for the premanufactured fire pump house? If so, can the government please provide a design? This would likely be far more cost effective than having contractors hire a structural engineer to design such a small feature.

Yes, foundations are required. The pump house slab/foundation shall be designed by the contractor based on the pump house size selected as stated in the Specification 21 30 00 Section 1.8.1. The fire pump house shown is a basis of design and the pad size/loads can change.

Drawing FX101 Keyed Note 7 along with Drawing FX103 Keyed Notes 1 & 2 identify Lean-To "B" to have new piping feeding existing piping to remain.

With the existing piping not shown with sizes on the drawings, please identify a demand GPM and psi for each point of connection so that we size this new feed piping correctly in our proposals.

The existing systems for the Annex and both Lean-To's were pipe schedule designed. Since there will be no alterations to the sprinkler heads (just replacment of), per UFC 3-600-01, the pipe schedule method may still be utilized to feed the sprinkler systems. Alternately, if the contractor wants to reduce the feed main pipe size based on the new fire pump performance curve, the areas may be hydraulically calculated per UFC 3-600-01. As-built sprinkler drawings have been attached and are to be used as information only. If hydraulic analysis is provided, all sprinkler head locations shall be field verified.

Drawing FX401 Keyed Note 12 states to set the pressure reducing valve to 90 psi.

May the pressure reducing valve be set based on hydraulic calculations of balancing the hangar bay overhead sprinkler system with the high-expansion foam system, so lot at it does not exceed 175 psi?

Yes, the pressure reducing valve may be set at a pressure corresponding with the hydraulic calculations where approved by the FPE. The contract documents are only a basis of design.

11/16/2016 79

Drawing FX402 Keyed Note 12 states that the backflow preventer is to be a double check valve. High-Expansion foam will be added to the water downstream via the inductor.

Will a double-check valve be accepted by the City of Oklahoma City, or will the backflow preventer need to be a Reduced Pressure Zone?

Provide a double check valve assembly as shown on the contract documents.
