36E77618B0089 – SD WLDR 4th Floor TECHNICAL QUESTIONS AND VA RESPONSE TRACKING SHEET

ITEM

NO.

Sheet AI301 Note “H” says the exam lights are to be Bergholt Chromophare F300 or equal and that the contractor is to “coordinate” installation with the manufacturer. Note “G” on the same page also says we are to “coordinate” the installation with the manufacturer. Sheet AI302 “equipment and furniture schedule” item 2 & 2A says the exam light and operating boom light are VA furnished and installed by the “contractor.”

0. Based upon the note on sheet AI301, we assume the “contractor” is actually the VA’s equipment “vendor” who is furnishing the lights, and we, as the general contractor, are only required to coordinate the installation of the structural members and install the power for the lights? Please confirm if this interpretation is correct. If it is not correct and we, the general contractor are to install the VA furnished lights physically, please provide a complete copy of the vendor's installation instructions for the lights & booms we are to install?

Per equipment and furniture schedule the VA shall purchase exam lights. The contractor shall coordinate the location of the exam lights with the manufacturer and the reflected ceiling plan. The installation prep for the lights shall be done by the contractor. The exam light vendor shall install the exam lights.

Contractor shall coordinate the light in the field with ceiling mounted items.

Power for exam lights is shown on the Power Plan EP104 (rather than the lighting plan). Contractor shall provide a junction box and power from the circuit indicated on sheet EP104. Junction boxes shown on sheet EP104 are notated with “CLG. EXAM LT.” Coordinate mounting with Manufacturer recommendations and other disciplines. Switch for control of these lights shall be integral to the unit.

Per the equipment and furniture schedule, the lifts on this floor shall be purchased and installed by the contractor. The intent of note “G” is to notify the contractor that there will be coordination with the lift manufacturer.

Power for lifts is also shown on sheet EP104. Receptacles for lift power are notated with “LIFT 96”” indicating that they are intended for the lift and shall be mounted at 96” A.F.F. In our experience these are generally battery powered and require only a 120v receptacle to charge.

9/21/18 Will the Contractors Superintendent be allowed to also serve in the roles for SSHO and CQC, or will a separate individual be required for either of these positions?

No, separate individuals for each

VA will provide 3rd party commissioning agent. General contractor shall be responsible for facilitating commissioning per specification requirements.

Alternate bids have been removed from the contract requirements complete. Please refer to revised 010000 General Requirements Specification.

Mold was found on one hard lid ceiling Please include spot remediation and repair of hard lid ceiling.

9/21/18 The statement of requirements below is an addition to our typical and standard VA CQC manager requirements, in that we must have someone on the job site full time for each respective discipline and the person must have a degree, and/or extensive experience. These types of requirements are difficult, if not impossible to achieve and will add tens of thousands of dollars to the project cost, if not more. There is also a Special Inspector specification that almost duplicates this QC matrix, so we would end up having a CQC, and QC specialist, and a Special Inspector. Is the VA expecting the Contractor to include the costs for what certainly appear to be duplicitous quality control personnel? Will the VA consider deleting these costly CQC requirements for this project and only requiring the more standard CQC and Material Testing / Special Inspection requirements, or can the CQC fulfill the role of the QC Specialists, or can the Site Supt. act as the CQC without the addition of the QC Specialists? See the cut and paste excerpt below:

01 45 00 3.4 C. CQC Personnel: In addition to CQC personnel specified elsewhere in the contract, provide as part of the CQC organization specialized personnel to assist in the CQC System Manager for the following areas, as applicable: electrical, mechanical, civil, structural, environmental, architectural, materials technician submittals clerk, Commissioning Agent/LEED specialist, and low voltage systems. These individuals or specified technical companies are employees of the prime or subcontractor; be responsible to the CQC System Manager; be physically present at the construction site during work on the specialized personnel’s areas of responsibility; have the necessary education or experience in accordance with the Experience Matrix listed herein. These individuals can perform other duties but need to be allowed sufficient time to perform the specialized personnel’s assigned quality controls duties as described in the CQC Plan. A single person can cover more than one area provided that the single person is qualified to perform QC activities in each designated and that workload allows.

AE does not agree with this assessment.

Clarification of the intent of this section as follows:

The requirement is to have an individual on site during the work of these trades that has either:

1.A degree as described in the Experience Matrix with 2 years of construction experience.

Or

2.A technician with no degree but 5 years’ experience.

While work is being performed on that trade. This individual may perform other duties including installation.

No, separate individual for each

The following limitations of use shall apply to existing facilities shown on drawings:

• Contractor shall coordinate materials storage locations;

• Contractor shall coordinate waste load out – including waste manifest signatures - with Owner

1.2 VARIATIONS IN QUANTITY

The quantities and locations of ACM as indicated on the drawings and the extent of work included in this section are estimated which are limited by the physical constraints imposed by occupancy of the buildings and accessibility to ACM. Accordingly, minor variations (+/- 5%) in quantities of ACM within the regulated area are considered as having no impact on contract price and time requirements of this contract. Where additional work is required beyond the above variation, the contractor shall provide

02 82 11 - 3 unit prices for newly discovered ACM and those prices shall be used for additional work required under the contractor.

1.3 STOP ASBESTOS REMOVAL

If the Contracting Officer; their field representative; (the facility Safety Officer/Manager or their designee, or the VA Professional Industrial Hygienist/Certified Industrial Hygienist (VPIH/CIH) presents a verbal Stop Asbestos Removal Order, the Contractor/Personnel shall immediately stop all asbestos removal and maintain HEPA filtered negative pressure air flow in the containment and adequately wet any exposed ACM.

If a verbal Stop Asbestos Removal Order is issued, the VA shall follow-up with a written order to the Contractor as soon as it is practicable.

The Contractor shall not resume any asbestos removal activity until authorized to do so in writing by the VA Contracting Officer. A stop asbestos removal order may be issued at any time the VA Contracting Officer determines abatement conditions/activities are not within VA specification, regulatory requirements or that an imminent hazard exists to human health or the environment. Work stoppage will continue until conditions have been corrected to the satisfaction of the VA. Standby time and costs for corrective actions will be borne by the Contractor, including the VPIH/CIH time. The occurrence of any of the following events shall be reported immediately by the Contractor’s competent person to the VA Contracting Office or field representative using the most expeditious means (e.g., verbal or telephonic), followed up with written notification to the Contracting Officer as soon as practical. The Contractor shall immediately stop asbestos removal/disturbance activities and initiate fiber reduction activities:

A. Airborne PCM analysis results equal to or greater than 0.01 f/cc outside a regulated area or >0.05 f/cc inside a regulated area;

B. breach or break in regulated area containment barrier(s);

C. less than –0.02” WCG pressure in the regulated area;

D. serious injury/death at the site;

E. fire/safety emergency at the site;

F. respiratory protection system failure;

G. power failure or loss of wetting agent; or H. any visible emissions observed outside the regulated area.

Employee exposure - The exposure to airborne asbestos that would occur if the employee were not wearing respiratory protection equipment.

Encapsulant - A material that surrounds or embeds asbestos fibers in an adhesive matrix and prevents the release of fibers.

Encapsulation - Treating ACM with an encapsulant.

Enclosure - The construction of an air tight, impermeable, permanent barrier around ACM to control the release of asbestos fibers from the material and also eliminate access to the material.

Equipment room - A contaminated room located within the decontamination area that is supplied with impermeable bags or containers for the disposal of contaminated protective clothing and equipment.

Fiber - A particulate form of asbestos, 5 microns or longer, with a length to width (aspect) ratio of at least 3 to 1.

Fibers per cubic centimeter (f/cc) - Abbreviation for fibers per cubic centimeter, used to describe the level of asbestos fibers in air.

Filter - Media used in respirators, vacuums, or other machines to remove particulate from air.

Firestopping - Material used to close the open parts of a structure in order to prevent a fire from spreading.

Friable asbestos containing material - Any material containing more than one (1) percent or asbestos as determined using the method specified in appendix A, Subpart F, 40 CFR 763, section 1, Polarized Light Microscopy, that, when dry, can be crumbled, pulverized, or reduced to powder by hand pressure.

Glovebag - Not more than a 60 x 60 inch impervious plastic bag-like enclosure affixed around an asbestos-containing material, with glove-like appendages through which materials and tools may be handled.

High efficiency particulate air (HEPA) filter – An ASHRAE MERV 17 filter capable of trapping and retaining at least 99.97 percent of all mono-dispersed particles of 0.3 micrometers in diameter.

HEPA vacuum - Vacuum collection equipment equipped with a HEPA filter system capable of collecting and retaining asbestos fibers.

Homogeneous area - An area of surfacing, thermal system insulation or miscellaneous ACM that is uniform in color, texture and date of application.

HVAC - Heating, Ventilation and Air Conditioning Industrial hygienist (IH) - A professional qualified by education, training, and experience to anticipate, recognize, evaluate and develop controls for occupational health hazards. Meets definition requirements of the American Industrial Hygiene Association (AIHA).

Industrial hygienist technician (IH Technician) - A person working under the direction of an IH or CIH who has special training, experience, certifications and licenses required for the industrial hygiene work assigned. Some states require that an industrial hygienist technician conducting asbestos abatement clearance inspection and clearance air sampling be licensed as an asbestos project monitor.

Intact - The ACM has not crumbled, been pulverized, or otherwise deteriorated so that the asbestos is no longer likely to be bound with its matrix.

Lockdown - Applying encapsulant, after a final visual inspection, on all abated surfaces at the conclusion of ACM removal prior to removal of critical barriers.

National Emission Standards for Hazardous Air Pollutants (NESHAP) - EPA's rule to control emissions of asbestos to the environment (40 CFR part 61, Subpart M).

Negative initial exposure assessment - A demonstration by the employer which complies with the criteria in 29 CFR 1926.1101 (f)(2)(iii), that employee exposure during an operation is expected to be consistently below the PEL.

Negative pressure - Air pressure which is lower than the surrounding area, created by exhausting air from a sealed regulated area through HEPA equipped filtration units. OSHA requires maintaining -0.02" water column gauge inside the negative pressure enclosure.

Negative pressure respirator - A respirator in which the air pressure inside the facepiece is negative during inhalation relative to the air pressure outside the respirator facepiece.

Non-friable ACM - Material that contains more than 1 percent asbestos but cannot be crumbled, pulverized, or reduced to powder by hand pressure.

Organic vapor cartridge - The type of cartridge used on air purifying respirators to remove organic vapor hazardous air contaminants.

Outside air - The air outside buildings and structures, including, but not limited to, the air under a bridge or in an open ferry dock.

Owner/operator - Any person who owns, leases, operates, controls, or supervises the facility being demolished or renovated or any person who owns, leases, operates, controls, or supervises the demolition or renovation operation, or both.

Penetrating encapsulant - Encapsulant that is absorbed into the ACM matrix without leaving a surface layer.

Personal sampling/monitoring - Representative air samples obtained in the breathing zone for one or workers within the regulated area using a filter cassette and a calibrated air sampling pump to determine asbestos exposure.

Permissible exposure limit (PEL) - The level of exposure OSHA allows for an 8 hour time weighted average. For asbestos fibers, the eight (8) hour time weighted average PEL is 0.1 fibers per cubic centimeter (0.1 f/cc) of air and the 30-minute Excursion Limit is 1.0 fibers per cubic centimeter (1 f/cc).
