USDA, ERRC Compressed Gas Cylinder Storage Areas Repairs and Safety Upgrades Statement of Work

Project USDA, Eastern Regional Research Center (ERRC), Wyndmoor, PA Compressed Gas Cylinder Storage Area Repairs and Safety Upgrades.

General Information

1.0 Scope of Work

The contractor shall furnish all labor, materials, equipment, tools, supervision, safety and disposal services necessary. All work must comply with applicable building codes, OSHA safety standards, and manufacturer installation requirements.

The purpose of this project is to rebuild and prepare two (2) dedicated compressed gas cylinder storage areas, each measuring 9 feet by 15 feet, to safely store a total of up to 40 compressed gas cylinders. Work includes surface asphalt and concrete removal, form and pour new level pads, and installation of OSHA‑certified cylinder storage racks to provide segregation, restraint, and labeling consistent with OSHA 29 CFR 1910.253 and relevant NFPA standards.

1.1 Working hours

ERRC working hours are 0730 – 1530. The facilities are closed on weekends and federal holidays.

2.0 Background

The Eastern Regional Research Center (ERRC) is one of four Regional Research Centers of the Agricultural Research Service, U.S. Department of Agriculture. The ERRC is home to the nation’s leading scientists and engineers who solve problems facing the U.S. today and tomorrow with fundamental, applied, and developmental research on agricultural commodities. Most of this research is conducted in the main building within two laboratory wings. The original building was constructed in 1940. Due to continuous upgrades and renovations, ERRC is very modern with respect to laboratory design and system condition.

Contractor Requirements

3.0 Technical Requirements

Repair Compressed Gas Cylinder Storage Area Surface and Racks for Safety Upgrades

3.1 Outside 8 x 15 Storage Areas (x2)

3.1.1 Demolition

· Temporarily relocate mixed industrial gas cylinders to a safe, code‑compliant holding area during renovation.

· Remove and dispose of all existing cylinder racking.

· Disassemble the current cyclone fencing to reinstall after all other steps are completed. Replace damaged or corroded chain‑link posts, top rails, and gate hardware as needed.

· Remove and inspect roofing and frame when the cyclone fence is disassembled. Replace damaged or corroded components of the roofing and/or frame.

· Remove existing asphalt and concrete slabs within both 9'×15' fenced enclosures.

3.1.2 Site Preparation

· Build forms to pour and maintain the existing 9'×15' footprints.

· Provide proper sub‑base compaction and moisture barrier.

· Install a new reinforced concrete slabs (x2) sized 9'×15', minimum 4"-6” thickness in both the empty cylinder storage cage and the full cylinder cage.

· Slope slightly for drainage away from cylinders and pedestrian paths.

· Ensure new slab is flush with sidewalk entrance, screed as needed.

· Finish surface to a non-slip broom texture

3.1.3 9' High Corrugated Metal Roof (x2)

· Reinstall galvanized tube frame with posts anchored to the new slab.

· Replace any corroded components with new components.

· Reinstall corrugated metal roofing panels with appropriate fasteners and trim.

· Provide minimum slope for drainage and direct runoff away from the sidewalk and enclosure.

3.1.4 Mixed Industrial Gas Storage Requirements

Mixed industrial gases typically include oxygen, nitrogen, argon, CO₂, acetylene, helium, hydrogen, etc. Storage must follow OSHA, NFPA 55, and IFC requirements:

· Provide and install fixed steel racks, chains, or straps to secure cylinders upright.

· Install required signage: (per NFPA 704 or as applicable)

· “Danger – Compressed Gas”

· “No Smoking / No Open Flames”

· Maintain clear access for cylinder delivery and emergency response.

3.1.5 Code Compliance & Permitting

· Comply with:

· OSHA 29 CFR 1910.253 & 1910.101

· NFPA 55 (Compressed Gases)

· NFPA 51/51B (if welding gases involved)

· International Fire Code (IFC)

· See measurements attachments for current enclosures.
