Add./Alter. Fire, Crash, Rescue Station; FKNN059220 The purpose of this amendment is:

1. Address Requests for Information (RFI’s) received as a result of the pre-bid conference/site visit and contractor reviews of the plans and specifications. This is a running document and the final document will be incorporated by amendment prior to bid opening.

Please remember to acknowledge receipt of this Amendment on the original Invitation for Bid (IFB) Form in the appropriate block.

All other terms and conditions remain unchanged by this amendment.

Q1.

There are drawings in the bid set that are stamped “Not for Construction” dated March 28, 2016. Are we to use these drawings for our price proposal?

A1.

As mentioned as the pre-construction conference and site visit the plans and specifications dated 28 March 2016 would be replaced with final plans and specifications. The Final plans and specifications dated 14 June 2016 were uploaded to FBO.gov on 13 July 2016. The plans and specifications dated 14 June 2016 shall be used for price proposal and performance of construction.

Q2.

Spec Section 232113 (Hydronic Heating) paragraph 3.1.A.1 and 3.1.B.1 require that copper joints be brazed instead of soldered, is it really necessary to have brazed joints?

A2.

Not necessary to have brazed joints. Joints can be soldered.

Q3.

Do you know which drawing the "Cutout dimensional characters" are on?

A3.

"Cutout dimensional characters" are meant to reflect exterior Bay #'s on the Overhead doors. They are found on A-201 & A-202.

Q4.

Page 1 of the SF1442 states time of completion is 540 CD, page 40 states it is 365 days.

A4.

The period of performance is 540 calendar days. The correction to FAR 52.211-10 has been incorporated into this amendment.

Q5.

Page 13 referenced Davis Bacon Wage Determination website, which when used, the date of the Determination is 7/1/16. Page 59 thru 64 of the SF1442 provides a Davis Bacon Wage Determination that is dated 4/1/16.

A5.

The most current Davis Bacon Wage Determination will be used. At the time of the Invitation for Bid, 4/1/16 was the most recent determination. This amendment incorporates the 7/1/16 determination.

Q6.

There doesn’t appear to be a requirement for Builder’s Risk Insurance. Please confirm that the General Contractor it is not required to provide BR Insurance for this project.

A6.

Builders risk is not required. Contractors shall carry insurance as indicated in FAR 52.228-5 – Insurance – Work on a Government Installation.

Q7.

Metal Lockers 105113: 2.3-I calls for recessed door handle and latch, but 2.3-J calls for a projecting turn handle and latch. Please confirm the desired handle and latch.

A7.

2.3-I calls for recessed door handle and latch is the correct option. 2.3-J should have been deleted.

Q8.

A8.

2.3-P, continuous Z base should be removed from specs. Drawings indicating section details with raised/tiled base is the desired detail.

Q9.

Drawing A603 Window and Storefront Types: Please provide clarification as to which of the elevations are storefront and which are aluminum windows. For example, elevation E10 is depicted as a window, but detail 1/A322 depicts it as a storefront.

A9.

A-603 is correct, as it shows Window types above the Header title "Window Types". Storefronts are labeled and located to the right of the window Schedule, but with "SF" designations See A94 for clarification on all window and storefront information.

Q10.

Reference drawing P-101. There is a new ¾” domestic HW recirculation line that begins in the ceiling of Conference Room 105 off the 1” domestic HW line. Should a balancing valve be installed there to control the hot water recirculation volume?

A10.

A balancing valve is not necessary in the hot water recalculation loop. There is a recirculation pump located in the boiler room that is controlled by an aqua-stat. The pump turns on/off to maintain the temperature of the aqua-stat. Nothing is achieved by adding a constriction (balancing valve) in the loop.

Q11.

Temporary Facilities & Controls 015000-3.4-I-4: Will temporary standpipes and hoses actually be required for temporary fire protection?

A11.

This is not anticipated as part of the proposed work, but they are included in the Specification to clearly establish them as Contractor responsibilities in the event they become necessary.

Q12.

Temporary Facilities and Controls 015000 & Closeout Procedures 017700: Both specifications make reference to pest control services, pest control field reports and pest control final inspection reports. Is there a specific expectation for pest control needs on this project?

For purposes of bidding, consider a minimum of ten (10) exterior pole/structure mounted speakers in addition to those shown as mounted to building (Fire Station).

Q32.

Reference demolition note #9 on drawing ED-103. Do these conduits contain existing wiring? If so, please identify the wiring, source, etc.

A32.

Existing conduits are assumed to contain wiring but size and quantity are unknown. Conduits traverse from 1st Floor Room 107 (Maint. Repair Storage) to above 2nd Floor Ceiling. For purposes of bidding, assume the following:

· (30) CAT 6 cables from 2nd Floor Comp. Equip. Room to 1st Floor

· (10) 120-volt, 1-phase circuits from Panel EP in Room 107 to 2nd Floor Areas (Lighting, FACP, etc.). Assume each circuit consists of (2) #12 AWG & (1) #12 GND conductors.

Contractor shall verify quantities and loads in the field.

Q33.

The new windows on the North Elevation are required to meet AT/FP blast hazard mitigation per UFC-010-01 as noted in spec 085113. Other than replacement of wood blocking, there are no upgrades to the existing exterior walls. Is the Contractor to assume the existing exterior walls are structurally sufficient to meet the AT/FP window installation?

A33.

Due to current standoff distance the existing openings and walls are adequately designed.

Q34.

We cannot find a specification for the aluminum diamond wall plate shown on drawings A-401 and A-404. Please provide.

A34.

Interior grade Aluminum wall covering is to be used. Basis-of Design product “Diamond Life, MaxTile F1, Aluminum wall tile” and associated trim details at all corners and top and bottom of wainscot heights, applied in accordance with manufacturers standards.

Q35.

We cannot find a specification for the industrial steel shelving that is shown on drawing A-101, keynote #5.

A36.

“Circulation corridors” include: Corridor #102, Corridor #119, Corridor #202 and Corridor 208.

Q37.

Roof Spec 075423, para 3.8.B states that the concrete roof pavers are to be installed with 3” space between adjacent pavers. Detail 3 on drawing A-332 notes that the concrete pavers are to be installed on a pedestal system and drawing A-114 plan indicates that the pavers are to be installed without a gap between the pavers. Please clarify the roof paver installation and pedestal system.

A37.

Roof pavers are to be installed to align with top of finished 2nd floor as noted on Key Note #16, drawing A-103. The pavers need to allow for water drainage to roof drain. Since the roofing will be sloped to drain, and a level paver surface is required, providing a 3” max pedestal height that is adjustable is required. This will allow for proper leveling coordination between roofing slope and finished floor elevation. (ie. Pavers near the terrace access door may be ½” raised pedestal, and pavers adjacent to roof drain may be raised 3”+/-. Field conditions will vary upon existing roofing removal and should be verified prior to installation).

Q38.

Detail 6 on A-405 shows a TV wall mount bracket but we cannot find a specification for it. Please provide.

A38.

This item is GFCI (Government Furnished, Contractor Installed). Locations on elevations are for blocking purposes within walls. Coordinate mounting heights with tv mounts in existing bunk rooms.

Q39.

Note 5 on drawing A-601 requires the Contractor to inspect all existing doors, frames and hardware. Please confirm that the Contractor inspects only and is not required to carry any repair work at this time.

A39.

Contractor shall inspect all existing door hardware and notify Government of any damaged hardware, and coordinate replacement in-kind to be included as a part of “finish upgrade ABI #3.

Q40.

E101, Key Notes 4 and 6: What is CFCI Smartboard? Is it “contractor furnished contractor installed”? If we are to provide the Smartboard, please specify?

A40.

CFCI = Contractor Furnished; Contractor Installed. Assume SMARTBoard Model SBM685i6.

Q41.

E101, Keynote 8 is shown next to a GB2 symbol (2-gang box)? Please provide more information as to what is required such as part numbers and wiring diagram? Or are we just to provide rough-in to the box?

A41.

GB2 = two-gang box. Devices are Wheelock UTA-WH series, 120-volt AC power, CAT 6 cable input.

Q42.

E101, Key Note 10; Please confirm that we are only to provide power to the VES devices and the controller? Is there a switching device for each VES at the control panel (do the conductors need to run thru the CP)? Is the EC responsible for control cabling, or the controls contractor?

A42.

Definitive system control will be based upon submitted/approved system and shall be coordinated during installation. For purposes of bidding, assume EC provides power to each VES Fan through the VES control panel. VES control panel requires separate power source by EC. Control wiring by controls contractor.

Q43.

E101, Note 4: Please provide more information as to what is required? Does each lighting pole get 1 speaker; what mounting height? Do we need more the building mounted exterior speakers shown for “exterior building areas”? Is the conduit for PA in Key Note 9 for the pole mount speakers, or does this go to the security turnstile?

A43.

Refer to Q/A #31. Conduit in Keyed Note #9 is for both Public Address System and turnstile.

Q44.

E01 Note 6: Please confirm if we should delete the DF’s as indicated in E603 Unit Heater Schedule note 1?

A44.

Confirmed – if ABI #5 is approved, DFs are deleted from scope.

Q45.

A45.

See A60, A61 & A62 for answers Q46.

From RFI Log, #23, Regarding the Existing Utility Pole and Overhead Electric Relocation: Will the owner cover the Emera/Fairpoint fees? If the contractor is to cover fees, could an allowance be established? Also, is there any underground conduit/cabling turning up at this pole? If so, please describe size, type, from-to?

A46.

Contractor is responsible for Emera/Fairpoint fees. No allowance will be established, however, a cost reimbursement change order will be contemplated with appropriate documentation and in accordance with the Federal Acquisition Regulation and its supplements. See updated response to Q23, Q80 and Q99.

Q47.

Drawing A-601 door schedule shows sectional doors, elevation sheet A-201 & A-202 show sectional but under keyed noted call out roll-up. Spec header is sectional and, R-value is sectional, thickness is sectional but under Door Assembly Overhead model 627 is coiling (roll-up) door. Please clarify.

A47.

All Doors labeled “OH” on drawing A-601 should be sectional doors, and should match existing door models. ABI #1 includes replacement of sectional doors, and would be new, but in-kind. They are not to be “coil-up” doors. The R-Value and thickness are accurate and the “Basis of Design” product listed should be deleted. Existing doors are to be matched. Verify-in-Field.

Q48.

Have not located the “Existing Hazardous Material Information” could those be made available through the FBO site?

A48.

File is uploaded to FBO.gov as annotated in amendment P00002.

Q49.

Drawing A-113 Note 9 specifies Stainless Steel floor grates, Specification 124816 2.3B calls for aluminum. Please advise which is correct.

A49.

Aluminum floor grates Q50.

Drawing A-503 Det 1 Drawing specifies galvanized embed and Specification 124816 2.4 says to match grating material. Please advise which is correct.

A50.

Drawing A-503 does not exist. Please clarify.

Q51.

Specification124816 2.3.B.1.a specifies Aluminum Color: As selected by Architect from full range of industry colors and color densities. This says industry colors as opposed to manufacturers colors, could this include custom colors?

A51.

Should be color selected by Architect from manufacturers standard finishes. No custom colors.

Q52.

Specification 076200 1.5.E.4 specifies Anodized Aluminum Samples: Samples to show full range to be expected for each color required. This section is under submittals but the specification does not give a color requirement. Please advise if color is from manufacturer standard or custom.

A52.

All exposed trim/flashing/coping/etc. finishes should be selected to match colors as noted on A-201 & A-202. This shall require custom colors if manufacturers standard colors cannot be matched.

Q53.

Specification 084113 2.10A specifies Baked-Enamel or Powder-Coat Finish: AAMA 2603 except with a minimum dry film thickness of 1.5 mils. Comply with coating manufacturer's written instructions for cleaning, conversion coating, and applying and baking finish. The exposed aluminum for storefront appears to be custom coating with no color chosen, is it the intent that all exposed aluminum will match this custom color?

A53.

Yes, for storefronts and windows.

Q54.

Drawing A-401 Shows aluminum diamond plate wall covering. It seems there is no spec section or product information regarding this.

A54.

Q55.

Drawing S-502 #5 shows an aluminum handrail welded to a steel beam. Aluminum and steel cannot be welded together.

A55.

Hand rail to be galvanized steel Q56.

Drawing C-502 #4 shows a steel post with aluminum rails. Again aluminum and steel cannot be welded together.

A56.

Hand rail to be galvanized steel Q57.

Drawing S-102 Column line A.75 shows HSS 5x5x3/4 in several locations. Square tubing of this wall thickness is not available. 5/8” thick is the thickest available in that size.

A57.

These columns should be HSS5x5x3/8.

Q58.

Drawing S-102 Section 1/501 seems to be mislabeled.

A58.

This section cut should be 1/S502.

Q59.

Drawing C-502 Detail 6 shows to use Stainless Steel Nosing’s. Spec section 055000 2.8A. Stair nosing’s are to be cast aluminum. Please specify a make and model and material you would like for the nosing’s. These can greatly vary in cost.

A59.

The nosings should be stainless steel.

Q60.

Regarding Window Treatments: A102 shows 20 sections for window E10, A201 shows 24 section, which is desired?

A60.

A-102 showing 20 sections is accurate. This allows detail 1/A322 mullion to align with new partition demising Fitness room 213 & Dining/Living/Day room 210 Q61.

Regarding Window Treatments: How are the window treatments to be divided for window E10, specifically how to avoid the building columns? Shall each bay be treated separately?

A61.

Window treatments shall be of equal lengths to maximum width possible per manufacturer standard, running entire window run. Where a column breaks a window run, the treatments shall fit tight to the wall/column surfaces, leaving minimum required working clearance as per manufacturer’s installation standards.

Q62.

Regarding Window Treatments: A102, Room 205 – Window E9 is not sectioned like the window elevations, is this to be treated as a one track unit or will each bay receive its own vertical? Same question for the shades.

A62.

Both window treatments are to run continuous of full window width. (Windows E4, E5 & E9 shall have 1 shade/1 treatment each. If window runs are too long for one continuous treatment, then it shall be broken up to 2 equal treatments, or 3 equal treatments, etc. Minimum # takes priority.)

Q63.

The final project specifications and drawings were posted to FBO. What changes were made from the pre-final, B2 plans and specifications?

A63.

Modifications from the B2 to the B3 submission for the Fire, Crash/rescue Station project were completed in response to the Government review comments received 5/17/16. One additional plan sheet was added to the set, Sheet P502, Sanitary Vent and Riser Diagrams. Additional Specification sections included 074113.16 - Standing Seam Metal Roof Panels, 236313 - Air Cooled Refrigerant Condensers, and 283500 - Refrigerant Detection and Alarm. Specification section 238126 - Split System Air Conditioners was removed.

Q64.

Please advise if widows E1, E4, E5 and E9 are to receive BOTH shades and verticals. Intent is unclear.

A64.

As per Key note 10a, on drawing A-114, Window E4, E5 and E9 receive both. E1 only receives blinds, not roller type sunshade.

Q65.

A-102 --- Rm 205 ---- do not see that window Type E9 is sectioned off--- is this correct? A) Are these to be treated as one track unit? Or each bay to receive its own vertical? B) ALSO if shades are desired for this window, same question?

A65.

See response to Q62 above. Window type E9, shows mullion locations on A-603. This sheet applies for all window/storefront mullions.

Q66.

A-102 ---- has 20 sections for E10; A-201 ---- shows 24 sections. Which is right?

A66.

Previously answered in question 60.

Q67.

Shelving and clothes rods. Where do the rod and shelf apply?

A67.

Shelving and clothes rods were previously designed to be in room 108. They are no longer included.

Q68.

Due to the timing of the final specifications and plans, will the bid date be extended?

A68.

The bid date will be extended to 28 July 2016 at 1:00 P.M.

Q69.

In reference to drawings A-602, A-602 & A-604, the storefront is specified as 451UT which is a double thermally broken system that is blast tested and is only available as center glazed as shown on details 7, 8, 9 on A-604. However, page A-603 Window Schedule calls for front glazed on all storefront. At the same time page A-602 shows front set storefront door framing (details 4 and 5). The spec also asks for 451UT front glazed, which is not an available product. Possible solution: SF1, SF1A, SF2 and SF3 should be 451UT or similar brand center glazed storefront. All window types should actually be 451T VG storefront (which is front set) with operable 8225TL windows as drawn.

A69.

All Storefront labeled with “SF” designation can be 451UT (or approved similar) center glazed. All windows can be 451T VG (front set) with the operable option to match desired 8225TL windows. All storefronts and windows must maintain ATFP requirements and thermal requirements listed in specifications See A94 for clarification on all window and storefront information.

Q70.

In reference to drawings A-604, A-332, A-313 & A-314, the window specification calls for 8225TL operable project out windows. In RFI #1 the windows are said to all be 8225TL, some fixed and some operable which matches the details on A-604. However page A-332 detail 1 shows one of these same windows as front set storefront, not an 8225TL window, pages A-313 and A-314 show these windows as either front set storefront or curtainwall. To add to the confusion, window E10 is drawn connected to SF3 at the corner where they meet? There isn’t a detail for this and I don’t have any idea how this would work other than by building a corner post in the building that the two framing types are butted up to on either side. Possible solution: Just to throw it out there, the 8225TL window can be build many ways. It can be an operable window installed into storefront, or it can be a window in and of itself. 451UT storefront is only available as center glazed. 451T VG (front/back set) is blast tested.

A70.

Please see answer to Q69 above. In addition, the Basis of design products (Kawneer) offer typical corner detail solutions that should be followed. Since window E10 and Storefront SF3 are fixed systems, provided by same manufacturer, the corners shall be of one corner detail, with steel reinforced mullions as required, per manufacturer's standard requirements. See A94 for clarification on all window and storefront information.

Q71.

Specification Section 283500 has been added to the revised specifications issued on 7/13/16 for refrigerant detection and alarms; however, the drawings do not show any of this system. Please provide corresponding drawings to show device quantities and locations for this system on the electrical drawings.

A71.

A room level refrigerant monitoring system will not be installed for this project. Pressure sensors shall be installed to monitor the refrigerant pressure in the overall Variable Refrigerant Flow (VRF) system.

The following shall be performed:

Contractor shall install two (2) pressure sensors at each outdoor condensing unit to monitor the high pressure side and low pressure side of the refrigerant piping. The sensors shall provide a 4-20 ma output signal designed to measure a range from 0 to 725 psi (based on condensing unit manufacturer’s operating pressures). If the pressure is not in the defined range (per the manufacturer’s installation manual), an alarm signal shall be sent to the Fire Alarm Control Panel and the Building Management System.
