VA Responses

Q1:

How many total mils are required (DFT) for the polyurethane coating system?

Q1 VA Answer:

64 wet mils (minimum) for the base coat. Additional mils for top coat, dependent upon product selected. For non-slip applications (i.e. walk pads) another additional layer is applied over the base coat (containing sand), further increasing the mils.

Q2:

Is closing down building operations in sections an option during application?

Q2 VA Answer:

It may be requested by the contractor; however, sufficient notice must be provided to allow the COR to coordinate based on the impacted areas of operation. Weekend work or after-hours may also be considered as alternatives if necessary.

Q3:

Are the building cranes operational and in use currently? This will be important to know for how roof application will need to be done in those areas.

Q3 VA Answer:

The contractor may consider using the existing roof hoist/lift equipment as an alternative method for transporting materials to the roof, provided that the equipment is tested and certified for its lifting capacity at the contractor’s own expense. However, the contractor is responsible for providing their own lifting equipment unless otherwise approved.

Any use of hoisting/lifting equipment must comply with all applicable safety standards, and the contractor will be held liable for any damage caused to roof anchors, the roof membrane, building structure, overhangs, or surrounding areas during the lifting operations.

Q11 VA Answer:

Q12:

Please identify all air handler intakes.

Q12 VA Answer:

Contractor to request mechanical as-built drawings from VA for air handler intake locations.

Please note that none of the AHUs / RTUs located on the roof will be relocated during this reroofing project.

Q13:

Do all air handlers need to have HEPA filters on them when work on specific roofs is taking place to prevent debris, chemical and other material from entering in the hospital spaces?

Q13 VA Answer:

From a Mechanical perspective, additional filtration at the outside air intakes (such as charcoal or HEPA filters) probably isn’t necessary. The main concern with adding extra filters is the increased pressure drop, which could affect overall system airflow. Since the hospital is designed with precise pressure relationships between various rooms, introducing additional resistance in the intake path could unintentionally disrupt that balance and lead to downstream issues. The TREMCO AlphaGuard BIO Base Coat, BIO Top Coat, and FC LO – Field are all virtually odorless and low in VOCs, so I believe the existing AHU filters should be sufficient. See screenshots below:

It should be noted that feedback/response is based on the Basis of Design (BOD) Tremco products. If alternate products are considered, specifications should match from a performance standpoint.

Q14:

Are any air intake handlers able to be shut down during construction to allow for the reduction in HEPA filter placement? If so, which ones and for how long?

Q14 VA Answer:

The intent is to not relocate any AHUs / RTUs on the roof during this reroofing project. Apart from any shutdowns required regarding any new duct / duct insulation associated with RTUs AMB-3A and AMB-3B (see sheets MP124C & MP124F) no AHU / RTU shutdowns are necessary.

Q15:

Are the various roofs able to be turned back over to the VA after they have been verified by the manufacturer and a warrant has been issued for those roofs or are all roofs going to remain under the care custody and control of the contractor till the final roof is completed?

Q15 VA Answer:

Due to the multiple floor levels within Building 1, it is reasonable to turn the space back over to the VA only after it has been verified by the manufacturer, a warranty has been issued, and the VA has had the opportunity to conduct a final walk-through with all punch list items completed and verified. The contractor will be required to submit a phasing plan that outlines this process.

The plan will be subject to review and approval by both the Contracting Officer and the Contracting Officer Representative.

Q16:

Will the telecommunication work be an afterhours or weekend scope of work to limit the impact to the facility?

Q16 VA Answer:

At this time, we do not anticipate any service impacts, so work during normal business hours is acceptable. However, when the contractor submits a detailed schedule, we will need to review it with our Technology Coordinator to assess any potential service disruptions. If it is determined that the work will impact operations, we may require the work to be performed after hours or on weekends to avoid interference with ongoing services.

Q17:

Will trash and debris need to be removed daily from the roof or can it be removed a few times per week, as long as the safety is maintained.

Q17 VA Answer:

General rule of thumb is to maintain “good housekeeping” for any worksite by keeping the area clean as possible and removing any trash on a daily basis. We have critical infrastructure on the roof e.g., air handlers, cooling equipment, elevator rooms etc. We would want to minimize the impact of a potential fire or other unseen events to the equipment or roof. Therefore, all debris must be removed from the roof at the end of each workday.

Q18:

Is there any engineered tie off points on the penthouses or will those require the installation of parapet wall guardrail system? If so, please identify them on the plans.

Q18 VA Answer:

Unknown. If tie off points exist on these roof overrun areas, they are not present in the as-builts and would have to be verified in field.

(Repeated question from Q4) Q19:

Confirm that all single ply membrane @ parapet walls and top of mechanical platform are not in the scope of work

Q19 VA Answer:

Confirmed.

Q20:

Is it the intension to terminate the coating below counterflashing in all areas?

Q20 VA Answer:

No, the intention is to apply the coating at counterflashing per detail B3/AE560.

Q21:

Are exposed single ply parapet sections also to be restored?

Q21 VA Answer:

No, roofing restoration terminates at the counterflashing per detail B3/AE560.

Q22:

Per site plan that's labeled in alphabetical roof sections , are any of these service elevators accessible for contractor use?

Q22 VA Answer:

To avoid disruption to patient care and occupied work areas, this project should prioritize exterior access over interior access whenever possible. We understand that some areas may have limitations that require interior entry therefore it is critical that all contracted personnel, including subcontractors whose employees require routine physical access, must request Non-Personal Identity Verification (PIV) access.

As part of the comprehensive work plan, contractors must provide an access strategy for each building level, detailing how access will be achieved from the exterior or, if necessary, through the interior when no other alternative is feasible.

Q23:

Can a lightning protection plan be supplied?

Q23 VA Answer:

If as-built lightning protection system plans are being requested, please request from the VA.

New lightning protection plans are to be provided by the LPS installer.

Q24:

Lightning protection was not visible on all roofing sections. Are the areas that currently do not have protection in the SOW?

Q24 VA Answer:

The intent of the installation is to provide a complete, fully functional lightning protection system in accordance with the relevant codes. The new system must be able to be certified. All areas that are required to be protected by a lightning protection system are considered in scope.

Q25:

Per schedule 182 calendar days is the requested duration of the project. How many weather related days will be grated?

Q25 VA Answer:

This is sufficient time for construction, and with keeping with the full duration of 182 days to account for any delays. The 182 calendar period of performance accounts for any potential delays for weather.

For our climate in Las Vegas, we see in manufacturers recommendations that this product should not be installed when surface temperatures exceed ~120°F (49°C), or when air temperature above 95°F (35°C). The ideal substrate application temperature is 50°F to 90°F (10°C to 32°C). In Las Vegas, this usually means that installation should NOT occur from late morning through early evening (10 AM – 6 PM), from June to early September. And in general the best application time is early morning (sunrise to ~9:30 AM) during spring, fall, or early summer.

Q26:

Do all coating alternatives meaning base and top-coat need to meet all requires per 07 01 50.91 if it meets warranty duration?

Q26 VA Answer:

Yes. Alternatives should meet warranty and performance criteria of specification.

Q27:

The proposed coating system has installed temperature restrictions. Are hot weather delays from the coating manufacture considered or is the 182 day projected time frame include all variables?

Q27 VA Answer:

See answer on Q25

Q28:

Is all internal plumbing accessible with drop ceiling or is there drywalled areas?

Q28 VA Answer:

Conditions may vary, drywalled in some areas and drop ceiling in others.

Q29:

Per drawings on a previous project at the facility, drawings called out for areas that lightweight concrete. Can a map of decking areas be supplied?

Q29 VA Answer:

VA can provide as-builts showing areas of lightweight concrete. The design team can provide a graphical map showing these areas if necessary.

Q30:

If lightweight concrete is under the wet areas to be removed, there is a chance that lightweight may need to be repaired. This may cause an open roof situation due to a 24 hr dry time before it can be covered up. Can the government confirm yes or no if lightweight is under the areas of roof removal?

Q30 VA Answer:

Design team can verify based on response to Q29 above.

Q31:

Are there any visible areas of rusted metal B decking in the areas to be removed?

Q31 VA Answer:

No.

Q32:

The loading dock is to be used as a temporary laydown area per plan. What duration will this area be granted to the contractor chosen?

Q32 VA Answer:

The loading dock may be used as a temporary laydown area for unloading or delivering materials. An enclosed waste dumpster is also permitted for use at the loading dock. The dumpster may remain at the loading dock for the duration of the project, provided there is adequate space and prior approval is obtained from the Facilities team.

To prevent cross-contamination from VA employees or other contractors improperly disposing of waste, we recommend using a top-enclosed dumpster. This issue has occurred in the past, so precautionary measures are highly encouraged.

Q33:

Plans from previous ITB for project VAMC Install Campus Fall Protection at the same facility require roofing scopes. May the awarded contractor of that project be different than this project, the situation of covering up a contractor’s warrantable work is unavoidable. Should it be assumed the coating contractor is also taking liability of the roofing installed for life safety?

Q33 VA Answer:

Based on the BOD product warranty information, the new roofing product warranty will extend to cover work by others as it relates to roofing materials, waterproofing, sealants, and Division 7 specification items. The warranty would cover liability associated with items pertaining to installation and performance of these items, but for items that concern life safety issues (i.e. the installation and fastening of a guardrail or anchor or roof stanchion to roofing structural members below) the roofing warranty would NOT cover. For example, if there is a leak around a point of attachment at an anchor, the warranty would cover this. If the anchor pulls out because it was not installed correctly, the roofing product warranty would not cover.

Q34:

HVAC – Drawings MP124C Sheet Note #1 and MP124F/ Sheet Note #1 - Indicate extent of insulation to be removed/ repaired on ductwork referenced in Detail D/ Dwg MP700

Q53:

Will any interior access be required (e.g., for access to stairwells, roof hatches, or mechanical/electrical rooms) that would trigger the need for interior containment, dust control, or negative air pressure zones?

Q53 VA Answer:

Since this project is expected to be entirely exterior work, interior containment, dust control measures, and negative air pressure zones are not anticipated or required. If any interior access becomes necessary such as for stairwells, roof hatches, or mechanical/electrical rooms, it will be coordinated in advance, and appropriate ICRA measures will be implemented based on the activity and location.

Q54:

Is the contractor responsible for implementing physical infection control measures (such as HEPA filtration units, temporary barriers, or particle monitoring) even if the scope remains entirely exterior?

Q54 VA Answer:

If construction activity is entirely exterior, negative pressurization and particulate monitoring are not applicable.

Q55:

Are there any known patient care areas or building zones directly impacted by the roofing scope that would require elevated ICRA mitigation measures?

Q55 VA Answer:

At this point, there are no identified patient care areas directly impacted by the roofing scope of work. We do not foresee any direct impact to patient care areas. However, the contractor should remain mindful of adjacent work zones that could potentially affect these areas. If it is determined during course of work that any activities may impact patient care spaces or pedestrian safety, the contractor must promptly notify the VA so appropriate ICRA mitigation measures can be evaluated and implemented.

Q56:

Will the contractor be responsible for removing loose equipment on the roof prior to installation?

Q56 VA Answer:

Yes, limited to Lightning Protection System and any “loose” blocking for ducts, lines, conduits directly laying upon roof surfaces. Excludes removal of MEP equipment mounted to pads or curbs.

Q57:

What are the hours of operation for crane use?

Q57 VA Answer:

This will depend on your crane pick/lift plan. Once submitted and reviewed, we can determine whether adjustments are needed, either by coordinating the work after hours or, if necessary, during regular hospital hours. If the lift affects any occupied floors within the approved area, we will require adequate time to coordinate and ensure those areas are cleared from employee and patient access during the lift.

Q58:

What are the available locations for the crane to be operated?

Q59 VA Answer:

The contractor must submit a crane pick/lift plan indicating the proposed crane location and the anticipated time impact. This plan is subject to approval by both the VA safety Officer and the COR. The COR will subsequently seek approval from various facility personnel.

Q59:

How many layers of coating is the contractor applying?

Q59 VA Answer:

65 wet mils minimum for base coat (16pprox.. 2 coats), plus additional layers where topcoat and walk pads are located. This is an estimate and the total number of layers depends on the selected product and manufacturers’ recommendations for installation.

Q60:

How far up the parapet walls is the coating going?

Q60 VA Answer:

8” min per detail B3/AE560.

Q61:

How many layers of material are currently on the roof

Q61 VA Answer:

With a reasonable degree of certainty, the roof is comprised of three plys of asphalt sheets with a modified bitumen cap sheet. This is based upon the as-built construction documents as well as the roof cores that Tremco performed as part of the assessment of the existing roof.

Q63:

Where is the contractor able to store equipment during install and after hours of install?

Q63 VA Answer:

Storage space within the VA Medical Center is limited, and we are unable to provide access or accommodate storage of privately owned equipment. However, contractors may utilize designated areas on the roof to store equipment and materials, provided all items are properly secured and strapped down due to the potential for strong winds. The contractor’s safety representative is responsible for inspecting and ensuring that everything is secure at the end of each shift. Materials must be properly weighted to prevent them from becoming airborne.

Please note that the VA will not be responsible for any equipment or materials left unattended or damaged overnight.

Q64:

Is the contractor replacing current pipe jacks on the roof or just coating over?

Q64 VA Answer:

If using Tremco AlphaGuard BIO products, coating over. However, if alternates are used refer to manufacturer recommendations for installation to meet roofing warranty.

Q65:

What are the hours of operation for the crew in each building?

Q65 VA Answer:

Since most of the work will take place on the exterior roof, the contractor will need to propose the working hours for each building. The key requirement is that construction activities must not interfere with the hospital’s daily operations and services. Note: VA hospital service hours are Monday through Friday, 8:00am to 5:00pm. The facility is closed on Saturday and Sundays.

Q66:

Will the crew be able to use the access door inside the hospital?

Q66 VA Answer:
