RTX33446

ePM# 65409

2. Project Location: TX0220MD

George HW Bush Federal Building 200 East Wall Street Midland, Texas 79701

3. Building Location Hours: Contractor will be allowed to work from 6:30am to 4:00pm. Normal business hours for this facility are Monday through Friday 6:00 am to 6:00 pm.

8. Description of Work: The project involves the rehabilitation of existing sanitary sewer and waste and vent piping mainly using the Cured-In-Place Technology (CIPP) method to minimize demolition and disruption of tenants as much as possible. Conventional method shall be used when piping is conveniently accessible and when necessary to connect lined pipe to branch drain piping.
