STATEMENT OF WORK (SOW)

FOR

Replace Steam and Condensate Lines

AT

Watervliet Arsenal Building 44 to 110

Project #: WO25PW043 Installation Management, Public Works Division

Facilities Engineering (TAWV-IMP-F)

PART 1 GENERAL

1.1 SUMMARY OF WORK

1.1.1 Project Description

a. This Statement of Work (SOW) defines the effort required for the replacement of underground steam and condensate lines between Buildings 44 and 110. The project includes the removal and replacement of steam supply lines and steam condensate return lines buried underground. Existing lines run in proximity to other underground utilities, as well as running under a roadway, concrete sidewalk, and concrete curbing.

b. This project also includes an option for replacement of the existing 2-½-inch underground compressed air line between Buildings 44 and 110.

1.1.2 Existing Conditions

a. The underground heating distribution system (UHDS) between Building 44 and 110 consists of an 8-inch diameter steam line and a 4-inch diameter condensate line. Underground utilities are known to exist near, under or over the steam and condensate lines at various locations. Utilities include but are not limited to electrical lines, telephone conduits, sanitary sewer, storm sewer, water, and compressed air. The location of these utilities will be marked as accurately as possible by the Government before excavation. Photos can be found at the end of this scope showing existing markings. However, the Contractor shall take great care during excavation so as not to damage the known and any unknown utilities. The approximate span of the underground piping is 360 lineal feet for the 8-inch and 360 lineal feet for the 4-inch lines. The depth of the steam and condensate lines appear to be 4-feet below grade at Bldg. 110 and 9-feet below grade at Bldg. 44.

b. This project will incorporate the removal of turf, sidewalk, curbing, and pavement. It is imperative to return all disturbed areas back to original or better conditions (prior to construction to include restriping parking stalls and roadways).

c. Asbestos insulation is assumed to have been removed during replacement of these underground lines back in 1986 according to the as-builts. Therefore, this portion of the work will not entail an abatement in addition to replacement. However, a minor asbestos abatement will be required for removal of approximately 10 lineal feet of pipe insulation, above the drop ceiling in the basement hallway (5’ on the 8” H.P.S and 5’ on the 2” L.P.C), so the pipes can be capped.

Trench plate thickness shall be at least ¾-inches for a 1-foot-wide trench and shall increase 1/8-inch for every foot of trench width up to a thickness of 1-¼-inch for a 5-foot-wide trench. Steel plates for trench widths greater than 5 feet require a special structural design by a Registered Professional Engineer. Trench plates shall not be overlapped or stacked on top of one another. At no time shall the length of any configuration of steel plates exceed 300 feet or be left in place for longer than 14 days without prior written approval from the Project COR/Engineer. The Contractor shall ensure that anchoring, strength and side supports are adequate to prevent collapse or movement of the plates.

i. Approach and ending plates shall be attached to the roadway by a minimum of 2 dowels pre-drilled into the corners of the plate and drilled 2-inches into the pavement. Subsequent plates shall be butted to each other. Fine graded asphalt concrete shall be compacted to form ramps with a maximum slope of 8.5% and a minimum 18-inch taper to cover all edges of the steel plates. Steel Plate Ahead (W8-24) signs shall be used and shall be placed in accordance with the MUTCD.

When steel plates are removed, the dowel holes in the pavement shall be backfilled with either graded fines of asphalt concrete mix, concrete slurry, or equivalent slurry approved by the Project COR/Engineer.

v. If the TCC zone affects the movement of pedestrians, adequate pedestrian access and walkways shall be provided. Pedestrians may be delayed for a short period of time for project personnel to move equipment and material to facilitate passage. Work zone personnel may also aid pedestrians as necessary.

i. Provisions for continuity of accessible paths for pedestrians should be incorporated into the TTC plan.

ii. Access to transit stops should be maintained (this includes the loading/offloading area at the Post Office, Bldg. 108).

iii. A smooth, continuous hard surface should be provided throughout the entire length of the temporary pedestrian facility. There should be no curbs or abrupt changes in grade or terrain that could cause tripping or be a barrier to pedestrians with disabilities.

iv. The width of the existing pedestrian facility should be provided for the temporary facility if practical. Traffic control devices and other construction materials and features should not intrude into the usable width of the sidewalk, temporary pathway, or other pedestrian facility. If it is not possible to maintain a minimum width of 60 inches throughout the entire length of the pedestrian pathway, a 60 x 60-inch passing space should be provided at least every 200 feet to allow individuals in wheelchairs to pass.

v. Blocked routes, alternate crossings, and sign and signal information should be communicated to pedestrians with vision disabilities by providing devices such as audible information devices or barriers and channelizing devices that are detectable to the pedestrians traveling with the aid of a long cane or who have vision disabilities.

vi. When channelization is used to delineate a pedestrian pathway, a continuous detectable edging should be provided throughout the length of the facility such that pedestrians using a long cane can follow it

vii. Signs and other devices mounted lower than 7 feet above the temporary pedestrian pathway should not project more than 4 inches into accessible pedestrian facilities.

vi. Equally as important as the safety of road users traveling through the TTC zone is the safety of workers. TTC zones present temporary and constantly changing conditions that are unexpected by road users. This creates an even higher degree of vulnerability for workers on or near the roadway.

i. All workers should be trained in how to work next to motor vehicle traffic in ways that minimize their vulnerability. Workers having specific TTC responsibilities should be trained in TTC techniques, device usage, and placement.

ii. Temporary traffic barriers should be placed along the workspace depending on factors such as lateral clearance of workers from adjacent traffic, speed of traffic, duration and type of operations, time of day, and volume of traffic.

iii. Operations entering and departing the workspace, and within the workspace, should be planned to minimize backing maneuvers by construction vehicles and equipment to minimize the risk of run-over and back-over crashes.

iv. A trained person designated by the employer should conduct a basic hazard assessment for the worksite and job classifications required in the activity area.

This safety professional should determine whether engineering, administrative, or personal protection measures should be implemented.

v. Upon completion of the project, the Contractor shall remove the bulletin board, signs, barricades, haul roads, and all other temporary products from the site. After removing trailers, materials, and equipment from within the fenced area, remove the fence. Restore areas used during the performance of the Contract to the original or better condition. Remove gravel that was used to traverse grass areas and restore the area to its original condition, including topsoil and seeding as necessary.

w. The Contractor shall also correct all deficiencies in the work that test reports and inspections indicate do not comply with the contract requirements.

3.1.2 General Excavation, Backfill, and Site Restoration.

a. The Contractor shall protect pedestrians, traffic, mechanical, electrical, and plumbing equipment, and utilities, surrounding construction, project site, landscaping, and surrounding building elements, from damage or injury resulting from project work.

b. If any pavement, trees, shrubbery, fences, poles, or other property and surface structures have been damaged, removed, or disturbed by the Contractor, whether deliberately or through failure to carry out the requirements of the contract documents, or the specific direction of the Project COR or through failure to employ usual and reasonable safeguards, such property and surface structures shall be replaced or repaired at the expense of the Contractor. If the Government specifies that the replacements or repairs shall be made by the Contractor, they shall replace or repair and restore the structures to a condition equal to that before the work began and to the approval of the Project COR and shall furnish all incidental labor and materials.

c. The Government will provide pavement markings, to the best of our ability, for any underground utilities. No cutting, digging or removals shall occur prior to completion of the “Dig” Permit (outlined in Section 1.4.1 above). The location of existing utilities indicated is approximate. The Contractor shall physically verify the location and elevation of the existing utilities indicated prior to starting construction. The Contractor shall protect utilities from damage during all phases of construction.

i. The Contractor shall be familiar with the provisions of this section, especially those relating to size and depth indications, color coding, center line or offset staking or marking and the location of underground facilities by designations other than staking or marking.

ii. Whenever the Contractor determines that a review of the staking, marking or other designation is necessary or that additional information is required, he or she shall so notify the Project COR.

iii. The Contractor shall be responsible for protecting and preserving the staking, marking or other designation until no longer required for proper and safe excavation or demolition work at or near the underground facility.

iv. Where an underground facility has been staked, marked, or otherwise designated and the tolerance zone overlaps with any part of the work area, the Contractor shall verify the precise location, type, size, direction of run and depth of such underground facility or its encasement. Verification shall be completed before the excavation or demolition commenced or shall be performed as the work progresses.

v. Powered or mechanized equipment may be used within the tolerance zone for removal of pavement or masonry but only to the depth of such pavement or masonry.

Verification shall be accomplished by exposing the underground facility or its encasement to view by hand dug test holes or by other means mutually agreed to by the Contractor and Project COR.

vi. If the precise location of an underground facility cannot be verified by the Contractor after diligent search at a reasonable depth within the tolerance zone as staked, marked, or otherwise designated, the Contractor shall notify the Project COR as soon as possible.

vii. After verifying the location of an underground facility, the Contractor shall not employ powered or mechanical excavating equipment closer than four inches in any direction from the staked, marked or otherwise designated or known outside diameter or perimeter of such facility or its protective coating unless agreed to in writing by the Project COR. Any such written agreement shall be furnished to the subcontractor by the Contractor, upon request.

viii. The Contractor shall take all reasonable precautions to prevent contact or damage to underground facilities and their protective coatings, including but not limited to, compliance with any reasonable directions or accepted engineering practices.

ix. In the event of contact with or damage to an underground facility, the Contractor shall immediately notify the Project COR.

x. All excavation or demolition in the immediate vicinity of the contacted or damaged portion of the underground facility shall be suspended until such portion is repaired and the operator advises the excavator that excavation or demolition may proceed.

xi. No backfilling shall be done by the Contractor in the vicinity of the contact or damage until the operator conducts an inspection and makes any necessary repairs; and the excavator shall undertake no repairs unless and until authorized by Project COR.

xii. The Contractor shall provide prompt and adequate support and protection for every underground facility located in the work area as is reasonably specified.

xiii. In the absence of any specifications, the Contractor shall provide support and protection in accordance with generally accepted engineering practice, including but not limited to shoring and bracing.

xiv. Support shall be at least equivalent to the previously existing support and shall protect the underground facility against freezing and against traffic and other loads. Support shall be maintained during excavation, during backfilling and, if necessary, after backfilling is completed.

xv. The Contractor shall backfill such excavation with materials and in such manner as specified by the operator or, in the absence of such specifications, with suitable materials and in such manner as will avoid damage to, and provide proper support for, such underground facility and its protective coating both during and after backfilling operations.

xvi. The backfill beneath and around any underground facility shall be properly compacted in accordance with generally accepted engineering practice. Heavy loads and excessive forces shall not be imposed on any exposed underground facility at any time during backfilling operations.

d. The Contractor shall be responsible to completely remove steam and condensate piping, valves, fittings, insulation, and all fastenings. All material and equipment removed shall become the property of the Contractor and shall be removed from Government property within one week and shall not be stored in operating areas unless otherwise directed.

e. The Contractor shall perform excavation, trenching, and backfilling as required by the system manufacturer’s design, as specified herein, and in accordance with Specification 31 WVA 00 (Excavation Requirements).

i. Contractor shall not lay new heating system piping when the trench bottom is muddy, frozen, or has standing water. The trench shall be kept in a relatively neat, clean, and dry condition. The Contractor shall always have dewatering equipment on hand.

ii. The Contractor shall stockpile material in their designated laydown area until testing is conducted. Contractor shall enlist the services of an accredited laboratory to test soil prior to disposal offsite. The Contractor shall not perform testing until Project COR has approved use of the testing facility. The soil should be sampled for the following:

i. Characteristics

ii. TCLP metals

iii. VOCs/SVOCs

iv. PCBs

iii. Hazardous and non-hazardous contaminated soil handling and disposal are regulated activities in New York State. Project soil contamination may include petroleum products, volatile organic compounds (VOCs), heavy metals and/or other specialty contaminants that require regulated handling and disposal by the contractor

iv. Contractor shall be sure to place any suspected contaminated soil on two layers of 6-mil poly, covered with a single layer of 6-mil poly, battened down, labeled with the Contractor’s company name, and preserved in a manner to prevent run-off.

v. For the purposes of this bid, the Contractor shall assume the excavated material is non-hazardous and can be disposed of offsite in normal fashion (recycling facility, landfill, etc.). Should the results come back differently, this will be handled as a ‘Change in Conditions’.

f. The Contractor shall use active engineering controls to minimize airborne dust, dirt, and other airborne contaminants during demo and all phases of construction. Contractor shall comply with OSHA's Respirable Crystalline Silica standard (1923.1153) for construction, which requires employers to limit worker exposures to respirable crystalline silica and to take other steps to protect workers (this includes WVA personnel in the immediate vicinity).

i. Always keep dust down, including during nonworking periods. Sprinkle or treat, with dust suppressants, the soil at the site, haul roads, and other areas disturbed by operations. Dry power brooming will not be permitted. Instead, use vacuuming, wet mopping, wet sweeping, or wet power brooming. Air blowing will be permitted only for cleaning nonparticulate debris such as steel reinforcing bars (not within manufacturing buildings). Only wet cutting will be permitted for cutting concrete blocks, concrete, and bituminous concrete. Do not unnecessarily shake bags of cement, mortar, or grout.

ii. Dust particles, aerosols and gaseous by-products from construction activities, and processing and preparation of materials must always be controlled, including weekends, holidays, and hours when work is not in progress. Maintain excavations, stockpiles, haul roads, permanent and temporary pathways, spoil and borrow areas, and other work areas within or outside the project boundaries free from particulates that would exceed 40 CFR 50, state, and local air pollution standards or that would cause a hazard or a nuisance.

iii. Clean up areas used for construction in accordance with Contract Clause: "Cleaning Up". Unless otherwise instructed in writing by the Project COR, remove traces of temporary construction facilities such as haul roads, work area, structures, foundations of temporary structures, stockpiles of excess or waste materials, and other vestiges of construction prior to final acceptance of the work. Grade parking area and similar temporarily used areas to conform with surrounding contours.

g. The Contractor shall prepare and implement a site-specific Health and Safety Plan (HASP), which will be adhered to by all personnel involved in the investigation, construction, and/or remediation at the site. HASP is a requirement of OSHA and is not subject to the approval of the New York State Department of Environmental Conservation (NYSDEC).
