STATEMENT OF WORK

Solicitation Number: W912WJ20Q0098 June 16, 2020

A. General Description of the Work to be Performed

The general description below is given to indicate the approximate scope of this project only. It does not limit the work required under the project documents.

1. Location and Background of Project: This project is at the Cold Regions Research and Engineering Facility (CRREL) in Hanover, NH, which is approximately 65 miles northwest of Concord, New Hampshire and is accessible from Exit 13 off Interstate 91 (I-91). The work to be performed is at the Main Laboratory Building at CRREL. This building is conjoined with the Laboratory Addition Building. While the two buildings primarily function as one facility, the structures are two separate entities.

A wall in the basement level, Room 58, of the two structures is constructed of original unfilled concrete masonry units (CMU) on the Main Lab side and drywall with aluminum studs on the Lab Addition side.

CRREL had awarded and administered an asbestos removal contract, which included the demolition of a portion of the aforementioned wall in the basement of the Main Lab/Lab Addition. During the course of demolition in August 2019, it was revealed that there exists a brick veneer on the west side of the CMU wall face. This brick veneer rests on the edge of the CMU wall, approximately one foot from the bottom of the first floor concrete beam. The existing brick veneer runs from the supporting CMUs to the roof of the Main Lab Building. Several wood studs were inserted in the gap between the CMUs and the brick veneer for temporary support. Demolition work was halted at that point and the asbestos removal work was not performed.

2. Description of Work. The work of this project involves the temporary stabilization of the wall to permit safe removal of asbestos containing materials, the removal of the asbestos containing materials, the removal of the suspended portion of brick veneer below the concrete beam and existing CMU wall, and installation of a new shoring system along the wall opening to support the remaining brick veneer above.

The shoring system includes providing and installing two structural steel beams with four supporting posts.

The Contractor shall note that space to perform the work is limited, as there is existing equipment located in close proximity to the wall. The work requires the relocation of one 4-inch abandoned electrical conduit.

Patching of existing CMU walls and existing columns is required. Finishes to final surfaces of installed materials, e.g. paint, gypsum board, or other, is not required.

Asbestos to be removed is found in two separate building features, both of which include asbestos-containing vermiculite material. Filler material in all blocks of the CMU wall is composed of asbestos-containing vermiculite, and plaster applied to three columns has asbestos-containing vermiculite as one of its components. All of this asbestos-containing material shall be removed. The CMU Wall is approximately 13 feet by 28 feet and is composed of 506 individual concrete masonry units. The three columns are each 9-inches by 14-inches and 169-inches high, with a 2-inch thick coating of the asbestos-containing plaster applied to the full dimensions and height.

The Contractor shall note that temporary stabilization of the existing wall and complete removal of all of the asbestos containing material, from the wall and from the three columns, is required prior to performing the permanent shoring and wall work.

The Contractor shall also note that only the rooms immediately surrounding the project work area will be unoccupied (the two rooms on either side of the wall to be repaired) during the performance period of this contract. The remainder of the Main Laboratory Building and the Laboratory Addition Building will be occupied by CRREL pesonnel.

The Contractor shall transport all solid waste off of the project site and dispose of it in compliance with Federal, State and local requirements for solid waste disposal. Upon completion of the construction work, the project site shall be returned to its pre-work condition.

Government policy is to apply sound environmental principles in the design, construction and use of facilities. As part of the implementation of that policy: (1) practice efficient waste management when sizing, cutting, and installing products and materials and (2) use all reasonable means to divert construction and demolition waste from landfills and incinerators and to facilitate their recycling or reuse.

Submit monthly documentation showing total amount, by weight, of construction debris diverted from landfills as a percentage of all construction debris on the project. The Contractor shall divert a minimum of 60 percent of waste and construction debris from landfill disposal. Include in documentation the total solid waste generated in tons, the total solid waste diverted from landfill in tons, and the total cost of the solid waste generated.

A Waste Management Plan shall be submitted within 15 days after Notice to Proceed and not less than 10 days before the preconstruction meeting. The plan shall demonstrate how the project waste diversion goal shall be met and shall include the following:

a. Name of individuals on the Contractor's staff responsible for waste prevention and management.

b. Actions that will be taken to reduce solid waste generation, including coordination with subcontractors to ensure awareness and participation.

c. Description of the regular meetings to be held to address waste management.

d. Description of the specific approaches to be used in recycling/reuse of the various materials generated, including the areas on site and equipment to be used for processing, sorting, and temporary storage of wastes.

e. Characterization, including estimated types and quantities, of the waste to be generated.

f. Name of landfill and/or incinerator to be used and the estimated costs for use, assuming that there would be no salvage or recycling on the project.

i. Identification of materials that cannot be recycled/reused with an explanation or justification, to be approved by the Contracting Officer's Representative.

Revise and resubmit the Waste Management Plan as required by the Contracting Officer's Representative. Approval of Contractor's Plan will not relieve the Contractor of responsibility for compliance with applicable environmental regulations or meeting project cumulative waste diversion requirement. Distribute copies of the Waste Management Plan to each subcontractor, the Quality Control Manager, and the Contracting Officer's Representative.

37. Trichloroethylene (TCE): The Contractor shall not bring on to the CRREL site any items/materials/equipment that contains trichloroethylene (TCE) as an ingredient. The Contractor is responsible to notify all of their subcontractors about this requirement. TCE can be found as an ingredient in solvents used for cleaning mechanical equipment, lubricants sprays, and some grease removers used for textiles. The list of trade names provided below is a partial listing of materials that should not be brought on site. In addition, if the Contractor uses a product containing TCE on equipment/materials/products off-site, the Contractor is responsible for ensuring that the equipment does not contain TCE residue that emits vapors at the CRREL site. Any item that may have been treated/cleaned with TCE off site should be unpackaged outside and wiped down with "TCE free solvent" prior to being brought into any building.

Trade Names and Synonyms:

Trichloroethylene Acetylene trichloroethylene Algylen Anameth Benzinol Chlorilen CirCosolv Germalgene Lethurin Perm-a-chlor Petzinol Philex TRI-Plus M Vitran for additionalrequirements pertaining to hazards and health effects of TCE, and therequirements for air monitoring.

38. Trichloroethylene (TCE) Monitoring:

A. The Contractor shall instruct each worker, prior to the start of work, on the hazards and health effects of trichloroethylene.

B. Existing Soil Contamination: In various locations at CRREL, soil and groundwater are contaminated with trichloroethylene (TCE). TCE is also present as a vapor in the soil at various locations at the CRREL facility, with highest concentrations around and beneath the Main Lab and Lab Addition buildings. In its pure state, TCE is a nonflammable, colorless liquid with a somewhat sweet odor and a sweet, burning taste. It is used mainly as a solvent to remove grease from metal parts, but is also an ingredient in adhesives, paint removers, typewriter correction fluids, and spot removers. TCE was used at CRREL in the past in support of the refrigeration process. Although TCE has not been used in the refrigeration process since 1987, several spills and leaks of TCE occurred on the CRREL property in the 1970s and early to mid 1980s. The Army is in the process of delineating the nature and extent of TCE contamination at CRREL and developing plans for remediation. TCE has been measured in soil vapor at CRREL and, to a lesser extent in ambient air near the Main Lab and Lab Addition. This vapor has also intruded into buildings at CRREL, prompting continuing efforts to mitigation exposures in those buildings. The Contractor should be aware of the properties of TCE and potential health effects.

C. Due to trichloroethylene (TCE) contamination on site, during all work in the Main Lab and Lab Addition buildings, and for any work involving soil excavation, the Contractor shall provide and maintain a photo-ionization detector (PID) in the work area suitable for detecting VOCs (especially TCE) in the air. The PID shall be used to monitor the breathing zone during work periods, and keep a record of periodic measurements. Should the breathing zone VOC level exceed 5.0 ppmv sustained for five minutes, the Contractor shall notify the Contracting Officer's Representative, who may conduct further testing. The Contractor shall halt work if the VOC level exceeds 25 ppmv and wait for VOC levels to dissipate. If the VOC concentrations do not dissipate to less than 25 ppmv within 15 minutes, the Contractor shall maintain the work stoppage and immediately notify the Contracting Officer's Representative. These provisions shall be described in the APP.

D. The Site Safety and Health Officer (SSHO) shall have a minimum of 3years experience conducting real time air monitoring (especially for TCE), and interpreting results for the purpose of identifying PPE requirements.

39. Contract Drawings and Information Drawings. Contract drawings showing the work to be performed under this contract and information drawings showing the original construction of the facility and related items are included with this document.

40. Photographs. Photographs showing the existing conditions of the wall and adjacent items are included in the contract drawings. The photographs are attached for informational purposes only. The Contractor shall make his own investigations of existing conditions in the field prior to the start of work.

The Contractor shall be responsible for any errors which could have been avoided by such investigations.

41. Damages. The Contractor shall exercise caution and follow sound construction practices in the conduct of the work to avoid construction-related damage to existing features to remain

42. Sequence of Work. The work shall be performed in the following sequence: existing conditions verification, preparation of submittals, material procurement, establish site safety, demolition, install new work features, and project close out. Coordinate this sequence with the requirements of Paragraph “Progress Schedule”.

43. Contractor's Receipt of Supplies. The Contractor shall be responsible for all arrangements for the receipt of materials and supplies at the job site. Government personnel are not permitted to receive or sign for items delivered to the site.

44. Storage Area. The storage area for use by the Contractor, for work and storage of equipment, materials, and trailers during the life of this contract will be determined at the Preconstruction Conference. The storage area will be located on the CRREL Facility property, in the vicinity of the project site. The Contractor shall confine its storage area to the limits as designated or approved by the Contracting Officer's Representative and shall be responsible for the security of the area.
