Trigon performed engineering and design services to facilitate the repair of the City’s collection system at various locations identified previously through CCTV inspections. Damage to the City’s sanitary sewer system was a direct result of Hurricane Katrina. The system was partially clogged by silt and debris and required immediate attention and cleaning to prevent or minimize overflow of raw sewage. The sanitary sewer system also sustained damages that require point / service repairs, obstruction removals and cured-in-place pipe (CIPP) lining which were designed as part of this project.
Trigon provided the following general services:
• Design of improvements, including site visits to verify field conditions and preparation of contract documents (specifications and drawings).
• Bid phase services to support the City in successfully bidding and awarding the construction contract
• Construction phase services, particularly with respect to conducting the pre-construction conference, technical review of submittals, responding to requests for information/clarifications, and support to the City in contract closeout procedures (including final change order).
The project was completed and closed out in 2011.
