The North Chemical Building (NCB) structural stability has been worsening since 2013 when water violently reacted with the lime stored near the building's roof. To immediately address the safety concern, make safe work was initiated to mitigate the failing south wall. A wire mesh is installed to prevent debris from falling and to stabilize the wall.
The next stage of work to safeguard employees and contractors from harm is to partially demolish the third floor, permanently removing the building's compromised portion. The building's demolition is not possible since electric and chlorine equipment in the NCB is critical to plant operations. The permanent sodium hypochlorite system will not be operational until July. Therefore, a temporary sodium hypochlorite system is needed to mitigate the hazard of Water Plant Operators entering the building daily to adjust chlorine feed rates during demo work manually.
GlobalTech, Inc., the same contractor working on the permanent sodium hypochlorite systems at the water treatment plant, requested a proposal on the temporary sodium hypochlorite system via a change order. A contract to purchase sodium hypochlorite is needed while the temporary system is in use and receives discounted rates on the same vendor's temporary system.
