The project is located at the VA Sierra Nevada Health Care System facility located at 975 Kirman Ave., Reno, Nevada 89502.

SCOPE

This construction effort shall consist of identifying and reporting the condition of the concrete, reinforcing and structural steel, metal decking and stair assembly; and remove, repair and clean the corroded steel beams, columns and metal decking, expansion joints, spalled concrete, failed traffic bearing waterproofing system, the deteriorated steel stair assemblies; and restriping of the second floor parking area.

2.2 The Contractor shall develop, prepare and submit construction documents such as construction plans and specifications and as-built plans.

Prior to doing any repair, Contractor shall provide a complete design submittal package including but not limited to design with seismic calculations (if needed) and structural remediation plans and documents, product information, installation procedures, Material Safety Data (MSD) sheets and Warranty certificates. Construction plans shall be signed and stamped by a Professional Engineer. The design submittal package shall be submitted 30 days from issuance of a Notice to Proceed.

Parking Garage Repairs

Concrete Repairs

Remove unsound concrete and existing failed patches to sound substrate, clean and inspect reinforcing steel, apply corrosion protection, install structural repair mortar, cure repaired areas, and apply protective coatings and migrating corrosion inhibitors. Reinforcing steel with more than 20% section loss shall be evaluated by the Engineer of Record prior to repair.

Slab Edge Repairs

Remove all metal edges and flashings for consistency. Repair deteriorated slab edges by removing damaged concrete and metal edge closures; Restore reinforcing steel, reconstruct edges with structural repair mortar, and apply protective coatings.

Reinforcing Steel Rehabilitation

Clean exposed reinforcing steel, apply corrosion protection, replace or supplement severely deteriorated bars as required, and restore concrete cover.

Metal Deck Repairs

Remove severely corroded deck sections, secure loose deck edges, remove debris, repair adjacent concrete as necessary, and notify the Engineer of Record if deterioration extends into supporting members.

Structural Steel Repairs

Clean corroded steel by mechanical means and apply zinc-rich primer or approved protective coating followed by a finish coat. Provide enhanced protection at column bases exposed to moisture and de-icing salts.

Traffic Coating Restoration and Striping

Remove deteriorated traffic coating, prepare deck surfaces and install new vehicular traffic coating over entire second floor parking area to restore waterproofing protection. Paint and re-stripe second floor parking lot afterwards.

Corrosion Mitigation

Provide anti-carbonation coatings, migrating corrosion inhibitor, reinforcing steel protection, and protective coatings for exposed structural steel to improve long-term durability.

Stair Rehabilitation

Repair stair deterioration wherever applicable.

Second Floor Concrete Floor Expansion Joint

Clean the joint and provide new expansion joint seals in-between flooring of the expansion joint. Expansion joint seal shall ensure that water flows through the flooring without any interference.

Second Floor Concrete Ramp Transition

Repair the metal edging and concrete transitioning between ramp and flooring. Provide waterproofing sealant to prevent water penetration.

Construction Requirements

The Contractor shall verify existing conditions, protect the structure during demolition, provide temporary shoring where required, coordinate work to maintain garage operations, submit required product data and shop drawings, follow manufacturer recommendations, notify the Engineer of Record of unforeseen conditions, and provide as-built drawings. The Contractor shall prepare and implement a traffic control plan that maintains safe vehicular and pedestrian access during construction. The plan shall include phased work sequencing, temporary lane or parking closures, barricades, signage, and detours to minimize disruption to facility operations and emergency access.

Quality Assurance

Structural repairs shall be performed by qualified concrete rehabilitation contractors and personnel. Quality control shall be the Contractor’s responsibility that shall include inspection of substrate preparation, reinforcing steel cleaning and condition, repair mortar installations, curing, protective coatings, waterproofing and flooding tests and final acceptance.

The Contractor shall develop a phased construction plan for the repair of the parking garage to take place preferably at night and over the weekends, and finish the repair with as little downtime as possible.

The Contractor shall provide a planned project schedule utilizing MS Project.
