B DISPOSAL OF DEMOLISHED MATERIALS

1 Do not allow demolished materials to accumulate on-site.

2 Remove and transport debris in a manner that will prevent spillage on adjacent surfaces and areas.

3 Flushing of concrete trucks is restricted to the location specifically designated for this purpose by the Contracting Officer’s Representative.

C DUST AND DEBRIS CONROL

1 Provide protective measures to control accumulation and migration of dust and dirt in all work areas.

2 Clean adjacent structures and improvements of dust, dirt, and debris caused by selective demolition operations. Return adjacent areas to condition existing before selective demolition operations began.

D PREPARATION

1 Remove all wood and wood scraps, sawdust, hardened concrete, construction debris, ice, snow, and other foreign materials from and between forms and from other areas in which concrete will be placed.

2 Thoroughly clean all areas to receive concrete to ensure proper placement of concrete.

3 Verify that Contracting Officer’s representative has completed all tests and inspections and they pose no objections to the placement of concrete.

E INSTALLATION

2021 Consolidated Projects Specifications Vehicle Lift Concrete Repair

1 Accurately position reinforcement and firmly support with approved devices and wire together to prevent displacement or distortion.

2 Place dowels and anchor them into position.

3 Provide proper cover around reinforcement, as indicated on the Drawings, or in conformance with ACI requirements when not shown.

4 Placement of reinforcement after concrete has been placed is prohibited.

F PLACING CONCRETE

1 Consistency and Quality of Concrete - Mix, transport, and place concrete so as to maintain proper consistency, to avoid segregation, and to insure placement in final position before initial set takes place. Re-tempering of concrete is prohibited. Control the rate of placement so that the concrete remains plastic and flows readily into spaces between the reinforcing bars, and can be worked into corners and around inserts without forming voids.

2 Vibration - Unless otherwise specified or directed by Engineer, vibrate all reinforced concrete. Use only approved mechanical vibrators operated by experienced operators.

Apply vibrators at uniformly spaced points not further apart than the visible effectiveness of the machine. Vibrate concrete sufficiently to produce satisfactory consolidation without causing objectionable segregation. Manually shake reinforcing bars to insure bond with the concrete. It is prohibited to use vibrators to transport concrete in the forms and to insert them into lower layers of concrete that have begun to set.

G FINISHING CONCRETE

1 General – Surfaces shall be brought to accurate lines and levels to receive subsequent finishes.

2 Deposit concrete and bring to approximate final grade. Bring surface to required grade using a straight edge.

3 Float and trowel the concrete after it has sufficiently set so that water and excess fine material is not brought to the surface.

4 Do not sprinkle dry cement or mixture of dry cement and sand on the surface to absorb moisture.

5 Tamp, where necessary, to achieve proper consolidation.

6 The surfaces shall be given two steel trowelings. The finished surface shall be free of trowel marks.

7 The finish shall be protected, and curing shall start immediately and be maintained for at least 7 days.

8 If correction of surface defects is required, submit to Contracting Officer’s Representative the measures and methods proposed.

H CURING CONCRETE

1 General - Cure concrete using the following methods or combinations thereof. Modify or augment these methods, or adopt additional protective measures, when required to compensate for changes in humidity, temperature, wind, or other conditions. Minimum curing period shall be 7 days.

2 Water Curing - Water curing during cold weather concreting is not permitted. Water curing is mandatory for all slabs-on-grade and structural slabs. Continuously keep concrete surfaces wet by covering with water, by continuous fog spraying, or by covering with burlaps, cotton mats, or other approved material thoroughly saturated with water and kept wet by intermittent hosing. Protect water cured concrete against freezing for the full curing period specified.

3 Curing Compounds - The use of curing compounds is not permitted during hot weather concreting, when they are incompatible with subsequent coatings, and when they may release pollutants, contaminants, or toxic materials. Curing compounds shall be used on walls.

L PATCHING CONCRETE

1 Mortar - Mortar for patching shall be of the same materials and proportions used for the concrete, except that the coarse aggregate shall be omitted and a sufficient amount of white cement shall be substituted for the grey cement in order to produce a patch whose color matches the color of the surrounding surfaces. Mortar shall not be thicker than 1 part cement to 3 parts sand. Keep mixing water to a minimum. Re-temper mortar, without addition of water, by occasional mixing to prevent setting. Using mortar which has begun to set or is more than 1 hour old is not permitted.

2 Application of Mortar - Thoroughly compact mortar into place and screed to leave the patch slightly higher than the adjacent surface. Leave undisturbed for one or two hours to permit initial shrinkage before being finally finished to match adjoining work. Patches exceeding 1" in depth shall be filled to within 1" of the surface and, after sufficient time has elapsed for shrinkage, final patching shall proceed. Keep all patches wet for at least 5 days.

1.0 Summary

Crothers Environmental Group, LLC (Crothers) is pleased to provide Smith Alvarez Sienkiewycz Architects with an asbestos inventory and limited lead survey for Building 140 of the Vermont Air National Guard base located in Burlington, Vermont. The site contains a structure with a footprint of approximately 16,500 square feet. The facility has a ground floor and basement level. The facility is scheduled for renovation.

The inspections were conducted on May 20 and June 27, 2016 by Christopher Clement, a Vermont-licensed Asbestos Site Inspector and Lead Inspector/Risk Assessor.

1.1 Asbestos-Containing Materials

The inspection was conducted to comply with renovation requirements set forth by the Vermont Regulations for Asbestos Control (V.S.A Title 18, Chapter 26), the U.S. Environmental Protection Agency Asbestos NESHAP Regulation (40 CFR Part 61 Subpart M) and the Occupational Safety & Health Administration (29 CFR 1926.1101 Construction Standard for Asbestos).

An asbestos-containing material is defined as any material containing greater than 1% asbestos.

The following materials were found to contain asbestos in concentrations greater than 1 %:

• Black mastic

2.0 Disclaimers

1) Some suspect asbestos-containing materials may be present in locations such as behind walls, in chases, above rigid ceilings, inside crawl spaces, etc. that were not observed or accessible to the Inspector. In the event suspect materials not identified in this report are discovered during renovation activities, the discovered material must be presumed as asbestos-containing and treated accordingly.

2) This inspection did not include any materials that may be underground (i.e. cement water and sewage pipes, buried trash and debris, etc.

3.0 Asbestos-Containing Materials

3.1 Scope of Work

Crothers was retained to collect bulk samples of suspect materials from the interior and exterior of the facility that may be disturbed during renovation activities. Since this was a renovation inspection, destructive sampling was not conducted of walls, ceilings and floors. If additional suspect materials are discovered during the renovation that are not reported, CEG should be notified.

VTANG, Building 14 0 - Burlington, Vermont

Jul y 11, 2016

3.2 Bulk Sample Inventory and Analytical Results

Ninety-five (95) bulk samples were collected (including layers) and delivered to Crothers Environmental Group, LLC Laboratory Division. Proper chain-of-custody procedures were followed during transport of samples. Crothers is a Vermont-licensed asbestos laboratory. All samples, unless noted, were analyzed by Polarized Light Microscopy "PLM" in accordance with EPA test method 40 CFR Part 763, Subpart F. The analyst visually estimates the percentages of identified asbestos. In the event that a sample appears to contain 2% asbestos or less, the analysis is repeated utilizing the point count method (a more statistically reliable method at lower concentrations).

The following table provides asbestos bulk sampling information:

4.0 Renovation Requirements

4.1 Non-Friable Asbestos-Containing Materials

Non-friable ACM or PACM is an asbestos-containing material that when dry cannot be crumbled, pulverized, or reduced to powder by hand pressure. The following materials were identified as non-friable ACM:

◇ Black flooring mastic

4.2 Regulations

The following regulatory agencies have regulations in effect when removing/disturbing non-friable

ACM:

4.3 Vermont Department of Health

The Vermont Regulations for Asbestos Control (VRAC) requires that all non-friable asbestos-containing materials that will be disturbed by renovation or demolition activities be properly removed prior to disturbance. VRAC Section 6 only requires minimal abatement procedures when removing non-friable materials. Vermont certified abatement personnel are not required. In short, the removal procedures include but do not limit:

◆ adequately wetting the material;

◆ removing the material in as large of sections as feasible; and ◆ properly packaging, labeling and disposing of the material.

The material cannot be sanded, sawn, chipped, ground, abraded or drilled.

4.4 Occupational Safety and Health Administration

(V)OSHA classifies these materials as Class II. This regulation is more stringent than VRAC, requiring the supervision by a competent person, specifically trained in a training course that meets the EPA's Model Accreditation Plan (Title 40 CFR 763, Asbestos-Containing Materials in Schools;

Final Rule and Notice) or a supervisor or project designer or its equivalent. Employees must also be trained, medically monitored and etc. Unless a negative exposure assessment has been carried out, full procedures are required under this regulation.

4.5 Asbestos Hazard Communication Requirements

This section applies to the communication of information concerning asbestos hazards in construction & general industry to facilitate compliance with OSHA 1926.1101 (construction) and 1910.1001 (general industry). Building owners are often the only and/or best sources of information concerning the presence of previously installed ACM. Therefore they, along with employers of potentially exposed employees, are assigned specific duties for hazard communication.

VTANG, Building 140- Burlington, Vermont

Building and/or facility owners shall notify the following persons of the presence, location and quantity of ACM or presumed asbestos-containing materials (PACM), at the work sites in their buildings and facilities. Notification shall be either in writing, or shall consist of a personal communication between the owner and the person to whom notification must be given or their authorized representatives:

• Prospective employers applying or bidding for work whose employees reasonably can be expected to work in or adjacent to areas containing such material;

• Employees of the owner who will work in or adjacent to areas containing such material; and

• On multi-employer worksites, all employers of employees who will be performing work within or adjacent to areas containing such material.

5.0 Lead-in-Paint

5.1 Lead Paint Sampling

A limited screening for lead-in-paint was conducted throughout the facility to determine whether it is likely that contractors would come into contact with lead during the course of the renovation. Note:

this does not exclude OSHA standards and lead-safe work practices should still be utilized when applicable.

EPA identifies lead-based paint as a surface coating containing greater than 1.0 mg/cm2 of lead or greater than 0.5% by weight. Testing was performed by Christopher Clement, a Vermont-licensed Lead Inspector and Risk Assessor, using the RMD Model LPA-1 XRF, Serial No. 3315. The XRF analyzer is designed to measure the lead content of surface coatings on a variety of building surfaces, substrates, and components . The measurement is rapid, nondestructive, and (according to the manufacturer) is capable of detecting lead concentrations that occur within numerous layers of various surface coatings.

5.2 Lead-in-Paint Summary

No detectable levels of lead were discovered on any of the tested surfaces. Therefore, we do not find a significant lead hazard, and the likeliness of workers coming into contact with lead during this renovation project is very low. However, if the contractor believes that lead-containing coatings are going to be disturbed by renovation, they are encouraged to refer to OSHA guidelines.
