# Contractor Question State's Response

1 Will any formal Commissioning be required?

Formal commissioning (Via a third party certified CxA) of the mechanical systems is not required.

Contractor shall demonstrate acceptable performance of all mechanical systems to the owner's representative.

Reference Section 20 05 48 Seismic Controls for Mechanical – Deferred Design:

Part 1.4 “Systems Not Requiring Seismic Restraint” lists hydronic heating piping as not requiring seismic restraint. The specification also lists equipment, piping, and ductwork exempted from seismic restraint for facilities with Ip = 1.0.

Per the specifications, only ductwork and equipment meeting specific weight and mounting height restrictions is exempt from seismic restraint.

More generally this facility has an Importance factor = 1.5.

Reference Section 20 05 48 Seismic Controls for Mechanical – Deferred Design:

Sheet S001 General Structural Notes, Seismic Loads indicates this facility is Seismic Design Category D, Risk Category IV, Importance Factor = 1.5.

Concur

Reference Section 20 05 48 Seismic Controls for Mechanical – Deferred Design:

Are the specification requirements of Section 20 05 48 appropriate? Does the specification need to be modified for Ip = 1.5?

Specification 20 05 48 is sufficient for this facility with an Ip = 1.5.

Specification section 32 12 16 paragraph 2.4 A calls for Class A, type I asphalt.

Class A asphalt requires high fracture aggregates that are meant for high volume traffic. State of Alaska DOT does not specify Class A asphalt often, even when paving high volume roads such as the Parks Highway or Airport Road here in Fairbanks. The type I designation specifies the use of 1” minus aggregate, which is not often used either. Type II is ¾” minus aggregates is the most common aggregate used in asphalt production in Interior Alaska. Please change this asphalt requirement to type II, Class B.

Pavement shall be type II, Class B

We do note that the heating equipment and piping shown on 1/M600 Heating Plant Detail will not fit into the space as allocated on 1/M301 2nd Floor Addition Hydronic Plan.

Non-concur. Distance between equipment may be modified as necessary to take up the available wall space as necessary for ease of installation and maintenance. Contractor may provide an alternate layout of the mechancial room for concurance by the owner's engineer.

Question for Telecommunication: 27 20 00, 2.9 A: Specifies ground bar for new equipment rack. Sheet E400 diagram of equipment rack doesn't show ground bar. Question: Where is the ground bar to be bonded? No details are provided.

This ground bar in the equipment rack is considered a secondary bonding busbar (SBB). The SBB shall be referenced to the nearest electrical panelboard to equalize potentials between them as well as to the primary bonding busbar (PBB) available at the TR in Rm 90.2 via a backbone bonding conductor (BBC). Size the bonding conductor at 6 AWG.

Please reference section 07 53 00, paragraph 2.4.A.2 & 2.6.A.2. These paragraphs note the fastening method of the insulation and coverboards are to be "fully adhered", meaning the insulation is to be adhered. However, under the same spec, part 3 execution, reference 3.3.C & D, this notes to mechanically attach the insulation and coverboard. Please clarify what is required, mechanical attachment or adhering the insulation and coverboard.

Fully adhered. See revised specification.

Please reference roof assembly R1 on page G101 of the contract drawings. The insulation is spec'd to be "Rigid EPS" and the insulation is spec'd to be 3 layers of 4" (12" thickness). The typical installation, utilizing EPS, would be to install the insulation in 2 layers of 6" vs the 3 layers of 4". Given that the design is for EPS, the boards can be readily manufactured in Alaska at the 6" thickness. Can the layers of insulation be reduced to a minimum of 2, while increasing the thickness to meet the required 12" thickness? This would also be way more cost effective for the Department, especially if the insulation and coverboard is to be adhered, by reducing a layer of insulation being adhered.

Either (3) layers of 4" or (2) layers of 6" is acceptable. See specification for additional requirements regarding minimum insulation R value on assembly sheet.

Please reference section 07 53 00, paragraph 2.4.A. This specifies the roof insulation product to be "SecurShield......". SecurShield is a Polysiocyanurate insulation. This differs from the "Rigid EPS" (Expanded Polystyrene) detailed under R1 roof assembly on G101 of the contract drawings. Please clarify design intent.

See updated specification for EPS

Please reference R1&R2 roof assemblies on page G101 and reference section 07 53 00 paragraph 2.2.A. Please note that both of these references specify for the EPDM membrane to be .090" (90mil) but also specify for the membrane to be REINFORCED. A reinforced .090 (90mil) membrane is not an offered product.

However, to achieve the specified 30-year duration on the warranty (ref.

1.10.B.4) .090" (90mil) membrane would be required. Please clarify if .090" (90mil) membrane is required, or if reinforced membrane is required.

See updated specification.

Please reference section 07 53 00, paragraph 1.10.B.1.. Please clarify the required warranted wind speed coverage. The referenced paragraph leaves this open to interpretation. Please note that page S001 notes the ultimate design wind speed to be 121 MPH and the nominal design wind speed to be 94 MPH. Please note that the maximum warranted windspeed offered by the manufacturers is 120 MPH.

120 MPH.

Further information for your consideration, if desired. Given the design windspeeds on S001, the maximum uplift pressure on S001 is -60 PSF (Zone 3). A typical, easily obtained, uplift rating for this type of assembly is a 90 PSF uplift rating (1.5 times stronger than the max design uplift and almost 2 times stronger than the Zone 1 -47 PSF). The typical -90 PSF uplift rating is usually obtained using the manufacturers standard (non-enhanced) fastening or adhesion densities/rates. The manufacturer's standard windspeed coverage is 55 mph, even though the assemblies are typically rated to easily handle the design uplift pressures (in Fairbanks). When an extended windspeed is required on the warranty the manufacturers will typically require enhanced fastening or adhesion densities/rates over what their standard or what the rated assembly requires, even when the roof assembly with standard fastening/adhesion is typically rated to resist 1.5 to 2 times the design pressures, costing the project owner more for adhesion/fastening. Disclaimer, just be upfront and honest, this is typical for the Fairbanks (interior of Alaska) area, and design uplift pressures will typically be higher in other wind zones of Alaska.

120 MPH.

Reference sheets M402 and M601. 2021 International Mechanical Code, Section

307.2.2 states “Condensate waste and drain line size shall not be less than ¾-inch size …”

This requirement applies to gravity drainage condensate lines. Pumped condensate may be 1/2" as indicated for pumped lines serving AC-1 and AC-2. AC-3 condensate drainage shall be gravity drained at 1/8" vertical drop ber foot horizontal using 3/4" hard copper after the condensate pump from a high point at Grid E to the mechanical room floor drain.

Reference sheets M402 and M601. Shall the ½” condensate drain piping be revised to ¾” piping?

Pumped condensate may be 1/2" as indicated for pumped lines serving AC-1 and AC-2. AC-3 condensate drainage shall be gravity drained at 1/8" vertical drop ber foot horizontal using 3/4" hard copper after the condensate pump from a high point at Grid E to the mechanical room floor drain.

On the civil plan views, chain link fencing, I only see the callouts for existing fencing. Where is the new fencing and new sliding gate to be installed?

Chain-link fencing was removed from this scope of work. Delete drawing sheets C710 and C711.

1/C711 'provide bollard at each gate post' - does this apply at both existing and new gates, or new gates only? Where on C100 or C200 are the gates?

Bollards at fence gates are no longer included in the scope of this work. See comment 30 response.

There is an orientation conflict between the two drawings that show the mobile shelving in Evidence Storage room A202 per spec section 10 56 26. - Layout drawing A311 shows the movable carriages in the middle of the room running N – S, but the structural drawing S430 for the mobile shelving rails shows the movable carriages in the middle of the room running in the E – W direction. The dimensions of the footprint also varies between these two sheets. Please clarify.

The floor area of both drawings are showing the same area. Use A311 for layout direction and finished size.

There is no elevation drawing or specifications for the shelving for the mobile storage system in spec section 10 56 26. We need to know the height of the mobile shelving and number of shelves, plus any specific details.

Height restriction of 108" stated in specifications.

See A311 for length and width.

Mobile storage system 10 56 26 states in Part 2 Products, 2.5 Floor / Ramp “Provide fire retardant treated floor/ramp materials when required by code.” - Does the local Fairbanks or Alaska State building code require fire retardant floor/ramp material?

Yes - utilize fire retardant floor/ramp material.

"Commissioning" is referenced several times in several different specification sections, but there is no specification provided for Commissioning. Please clarify if mechanical systems commissioning by a commissioning agent is required and if so, please provide a specification.

Formal commissioning (Via a third party certified CxA) of the mechanical systems is not required.

Contractor shall demonstrate acceptable performance of all mechanical systems to the owner's representative.

The basis of design Kingspan insulated metal wall panel has both a flat and non-embossed exterior finish. Would alternate products be considered if the exterior side of insulated metal wall panels is embossed?

Design intent is smooth metal panel to maintain continuity with existing facility cladding.

In 07 42 13.19, 2.3.A, it is specified to use 36” wide insulated metal wall panels.

Would 40” wide panels be allowable?

40" wide panels are allowable. Sheet A401 Exterior Elevations to remain as drawn for horizontal datum line references. Contractor is responsible for any dimensional coordination as a result of alternate widths and vertical joint alignments. Any variation in layout will require approval during shop drawings.

In 07 53 00 EPDM spec, 1.10 Warranty C 1 it calls out a 3 year installers warranty.

The standard is 2 year. Is a 2 year acceptable?

3 years required.

In 07 53 00 EPDM spec, Products 2.2A calls for 90-mil fleece back EPDM. Can the standard non-reinforced 90-mil EPDM be used in lieu of the 90-mil fleece back?

Substitutions: See Section01 60 00-Product Requirements.

In 07 53 00 EPDM spec, Insulation 2.4 A2 it calls for the insulation to be adhered.

Under execution 3.3 C1 calls for the insulation to be mechanically attached. The details on G101 show fully adhered. Which method is required?

Adhered.

In 07 53 00 EPDM spec, Insulation 2.6 A2 it calls for the cover board to be fully adhered. Under execution 3.3 D calls for the cover board to be mechanically attached. Which method is required?

Adhered.

In 07 53 00 EPDM spec, 3.5.F "provide daily on-site attendance of roofing and insulation manufacturer's representative during installation of this work". The EPDM and insulation manufacturer's are two different entities, and they don't offer this service. Can this requirement be eliminated if the warranties can still be provided? Or if daily special inspections will be required, can they be provided by a third party inspection agency instead of the manufacturer?

See revised specification.
