Attachment A: Statement of Work EBFD Balance Valve Scaffolding July 23, 2024

SCOPE

The Bureau of Reclamation, Elephant Butte Field Division, has a need to install temporary scaffolding for 77 days at Elephant Butte Field Division, located at 4696 Hwy 51, Truth or Consequences, NM 87901. The scaffolding must meet the salient characteristics as specified in the requirements of this document.

BACKGROUND

Elephant Butte Field Division is responsible for operations of Elephant Butte Dam and Powerplant. As part of our maintenance responsibilities, we have a need to work from an elevated position as we recondition four discharge conduits on the downstream face of the dam. This work will require sandblasting and application of marine grade protective coatings. The scaffolding will be erected in an area of potential engulfment and is therefore subject to the Facility Hazardous Energy Control Program (F-HECP).

REQUIREMENTS

The Contractor shall provide all labor, expertise, and equipment to install a support type temporary scaffold that allows access by Reclamation staff to complete the required maintenance tasks.

Physical Dimensions:

Working Platform Horizontal Length:

The length of the top tier working platform shall be 36 linear feet from end to end.

Working Platform Vertical Height:

The top tier of the scaffolding platform shall be positioned at the base of the 60” discharge conduits as indicated in Appendix A. The supported scaffolding shall be anchored to the concrete apron below the discharge conduits. The concrete apron is sloped at a 10° to 30° angle. The upright supports are expected to range between 12-18 linear feet for proper placement of scaffolding.

Working Platform Width:

The working platform shall be 48” wide to allow for the free and unencumbered movement of two workers to gain work access to the exterior and interior surfaces of the discharge conduits.

Working Platform Safety Requirements:

Toe Boards- Height and Gap: Toe boards should be at least 3.5 inches (9 cm) tall and have no more than a 1/4-inch gap at the bottom.

Strength: They must be able to withstand a force of 50 lbs. applied to them.

Guardrails- Top rail: The top edge height of top rails or equivalent guardrail system members must be 42 inches (107 cm), plus or minus 3 inches (8 cm), above the walking-working surface.

Midrail: Shall be placed at half the height distance between the working platform and top rail.

Platforms: Supported scaffold platforms shall be fully planked or decked. 1926.451(b) Access: Worker access from the top concrete deck above the discharge conduits to the working platform supported scaffolding shall be included in the scaffolding through approved OSHA methods as described in 1926.451(e)(1-6)

Criteria for supported scaffolds:

· Supported scaffolds with a height to base width (including outrigger supports, if used) ratio of more than four to one (4:1) shall be restrained from tipping by guying, tying, bracing, or equivalent means 1926.451(c)(1).

· Supported scaffold poles, legs, posts, frames, and uprights shall bear on angled base plates anchored to the concrete apron below the discharge conduits.

· Supported scaffold poles, legs, posts, frames, and uprights shall be and braced to prevent swaying and displacement.

· The platform must not deflect more than 1/60 of the span when loaded. 1926.451(f)(16).

· Each scaffold and scaffold component must support without failure its own weight and at least four times the maximum intended load applied or transmitted to it. 1926.451(a)(1) A qualified person must design the scaffolds, which are loaded in accordance with that design. 1926.451(a)(6)

· The anticipated load is 750lbs (2 workers @250lbs and 250lbs of equipment/materials).

Scaffolding Assembly/Dismantling Requirements:

· A contractor supplied qualified person as defined by 1926.451(a)(6) shall determine the scaffold design to meet the salient characteristics specified in this document.

· A contractor supplied qualified person as defined by 1926.451(e)(9) and 1926.451(g)(2) determine the feasibility and safety of providing fall protection and access for Bureau work from the provided scaffolding.

· A contractor supplied qualified person as defined by 1926.454(a) shall provide orientation and necessary training to Reclamation employees working on the scaffolds to recognize the associated hazards and understand procedures to control or minimize those hazards.

· Including direction on proper inspect of scaffolds and scaffold components for visible defects before each work shift and after any occurrence which could affect the structural integrity and to authorize prompt corrective actions. 1926.451(f)(3)

· Contractors to provide personnel meeting OSHA Scaffolding Competent Person Training for the erection and dismantling of contracted scaffolding as described in this salient characteristic document.

START AND COMPLETION REQUIREMENTS

Project Scope:

PERIOD OF PERFORMANCE: 9/30/2024 – 12/18/2024

Installation/Orientation:

Contractor shall arrive at the facility on or within a week after September 30th, 2024, by 8:00am to begin site preparation and assembly of the contracted scaffolding. Scaffolding assembly and orientation requirements shall be completed within close of business on the second day upon arrival. Additionally contactor staff will need to complete a 2-hour on-site Hazardous Energy Control Program training to become oriented with our lockout procedures as the worksite is located within a potential engulfment zone. The contractor job supervisor will also be required to provide a keyed padlock to be placed so that they may work under the clearance associated with this project.

Dismantling:

Contractor shall arrive at the facility on the 78th day by 8:00am to begin dismantling of the scaffolding system. This will complete the 77-day rental of the supported scaffolding. If different staff are deployed for dismantling, they will also be required to complete the F-HECP orientation training prior to work in the potential engulfment work zone.

WORK HOURS

Work shall be performed Monday through Friday, except for Federal Holidays, 7:30 AM to 4:00 PM. Any work outside the designated hours shall be arranged and approved prior to scheduling with the COR or Contracting Officer.

SITE CONDITIONS

Location for placement of the scaffolding is located at the base of the Elephant Butte Dam, 4696 Hwy 51, Truth or Consequences, NM, 87901.

The location is located 3.5 miles east on Hwy 51 from the intersection of N. Date and 3rd Street (Hwy 51) in Truth or Consequences, NM. The facility is paved and behind a security gate. Calling main office is required for entrance to facility.

Restrooms will be made available to the Contractor during the work hours 7:30 AM to 4:00PM.

The contractor is responsible for all clean up and for disposal removed material and waste materials or rubbish. The disposal of waste materials and rubbish shall be in accordance with all applicable Federal, State, and local regulations, standards, codes and laws.

SECURITY

All service locations under this contract are within secured areas. However not in sensitive areas. The contractor officer representative (COR) will arrange for the Contractors entry into the facility and inform the Contractor of security procedures. The Contractor shall comply with all security procedures. The COR or designee will accompany any contractor while on site for installation.

The Contractor shall supply the Bureau of Reclamation with the legal names of all employees who will be working under this contract.

SITE VISIT

A site visit can be coordinated with the Facility Operation Specialist, our Technical Contact at the Elephant Butte Dam, 4696 Hwy 51, Truth or Consequences, NM. It is recommended, but not required that interested Contractors attend the site visit to perform investigation as to the site conditions for scaffolding placement under this statement of work. The facility is historic and could present removal or installation challenges. However, the concrete apron on which the scaffolding footings are to be anchored to, will remain submerged until the end of September 2024 when operational releases have ended for the season. If the Contractor choose not to attend site visit to conduct investigations, he/she will nevertheless be charged with knowledge of conditions which reasonable inspection and investigations would have disclosed.

FINAL ACCEPTANCE

Final acceptance of the scaffolding has been dismantled and worksite has been cleaned up of related materials or debris. Any damage or distortion of the facility resulting from this contracting action shall be repaired by the Contractor at no additional cost to the government.

REQUIRED SUBMITTALS FOR QUOTE
