A. GENERAL OVERVIEW

The work consists of furnishing all labor, materials, equipment, traffic control, protection, surface preparation, waterproofing injection, joint sealant replacement, localized concrete repair, cleanup, and all incidental items required to stop water infiltration into the pedestrian tunnel beneath South Temple and restore damaged overhead concrete in localized areas.

The intent of the work is to:

• stop active water intrusion into the tunnel structure,

• create a curtain wall waterproofing barrier from the interior (negative side),

• replace failed exterior sealant at entrance structures,

• and return the tunnel to a clean, safe, watertight condition.

B. WORK HOURS AND ACCESS

All work shall be performed during nighttime hours only.

• Work window: 5:00 PM to 6:00 AM

• Tunnel must be fully cleaned, safe, and reopened for use by 6:00 AM each day

• No materials, equipment, or hazards may remain in the tunnel during daytime hours

Contractor shall:

• mobilize and demobilize daily within the allotted window,

• maintain safe pedestrian access outside of work hours,

• coordinate with the School District for any schedule adjustments.

• pedestrian and traffic control,

• protection of school occupants and public,

• temporary barriers, signage, dust control, and housekeeping,

E. EXTERIOR ENTRANCE SEALANT REPLACEMENT

At both tunnel entrance structures, remove existing failed or deteriorated sealant at joints where entrance structures meet adjacent concrete flatwork and curbs.

Install new sealant using Sikaflex 2c NS.

Work shall include:

• • removal of existing sealant,

• • joint cleaning and preparation,

• • installation and proper tooling of new sealant,

• • sealing of perimeter joints, corners, and visible leakage pathways.

Care shall be taken to protect historic surfaces and maintain a clean finished appearance.

F. CURTAIN WALL INJECTION WATERPROOFING

Perform curtain wall injection to stop active water intrusion and create a water cutoff behind tunnel walls and overhead areas.

Injection material shall be Sika Injection-101 US, a water-reactive polyurethane foam that expands upon contact with water and is designed for sealing active leaks in cracks, joints, and voids.

Work shall include:
