Description

This project involves replacing the boiler system in the Laguna Treatment Plant (LTP) Annex building. The existing gas-fired boilers, installed in the mid-1990s, serve as backup process heat supply and have reached the end of their service life without modern air emission controls. The scope includes providing, installing, maintaining, and removing a complete temporary outdoor boiler system to maintain required heating service during construction. The project requires coordination with the facilities department for shutdowns and compliance with site-specific safety requirements.
