2. In Building 5 Domiciliary in two similar stairwells, remove existing basement mesh panels with door and lock. Provide new mesh panels with door and lock. Provide new anti-suicide metal mesh panels inside stair center continuous vertically all three floors up to stair ceiling.

B. Summary of Building 11 Boiler Plant Work: Replace Stairs The successful Contractor shall perform the following work:

1. Conduct a site visit, field verify all dimensions and existing conditions.

2. Adhere to drawings, photographs, and specifications for additional project requirements and information.

3. Prepare and submit for approval complete shop drawings prepared by a licensed architect stair submittal that meets all applicable codes, including 29 CFR 1910.25(c)(2). Have a maximum riser height of 9.5 inches.

4. Remove and recycle off-site the existing metal stair system. Reference specification section 01 74 19 CONSTRUCTION WASTE MANAGEMENT.

5. Provide temporary barriers at exposed upper landing during construction.

6. The new stairs shall be a 180 degree turn to accommodate the rise run requirements and overall length of stair. Riser clear dimension shall be 30” wide, treads shall be 10-7/8” deep. Landing shall be minimum of 30” deep. Existing height and length to wall limits are indicated on the photographs. Stair assembly, tread, and handrail material shall match as close as possible in scale, stair width, and finish of the existing stairs

7. See specification 05 51 00 METAL STAIRS for Industrial Stair requirements.

8. A minimum of 24” clearance is required between the front of the emergency boiler stop devise on existing east wall when with layout of new stairs.

10. Provide a removable 10 gauge galvanized metal sheet plate direct to underside of upper flight of stairs that is removable for cleaning, similar to existing condition.

11. Provide all labor, materials, equipment, utilities, miscellaneous items, freight and delivery and all necessary valid licenses and permits for the work summarized above.

12. Ensure that all new materials are on site PRIOR to commencing work to minimize the duration that the existing stairs are not accessible for the VA.

C. Summary of Building 5 Domiciliary Anti Suicide Protection Work: Install Metal Mesh Panels in Two Stairwells The successful Contractor shall perform the following work:

1. Conduct a site visit, field verify all dimensions and existing conditions.

2. Adhere to drawings, photographs, and specifications for additional project requirements and information.

3. Prepare and submit for approval shop drawings for the mesh panel system to replace the section with the door/lock, and for the three-floor mesh panels at stairwells. Include in submittal all framing, hardware, mesh system, braces, anchoring devises, door fabrication details, and all work for a complete system.

4. Remove and recycle the Level 1 existing wire mesh cage at stairwells. Reference specification section 01 74 19 CONSTRUCTION WASTE MANAGEMENT.

5. Provide at Level 1 mesh panel system to enclose under the lowest level stair similar to existing. This system shall include a door and lock similar to existing. This mesh panel system material shall match the three-story stair mesh material.

6. Provide wire mesh panel system and framing extending from Level 1 up to ceiling above Level 3. The panel system shall be anchored at all four corners at each floor and at the top of the shaft to the ceiling. There is also a panel that shall extend from this shaft to the parallel wall to completely close at the top of the shaft. Include all framing, hardware, mesh system, braces, anchoring devises, door fabrication details, and all work for a complete system. Anchor the panel system at all four corners as required.

7. Paint at existing stairwell walls and ceilings may contain lead, so required removal procedures for fastening into these surfaces must follow specification section 028333.13 LEAD BASED PAINT REMOVAL AND DISPOSAL.

8. Include all work to patch and match existing materials and finishes all holes and connection points following removal of existing panels.
