The Problem

The first-floor contains the existing electrical switchboard, abandoned restroom facilities, hydraulic valve system controls, and gate valve operators. The basement houses a step-down transformer, pumping equipment, and a ventilation blower. All of these elements required an upgrade.

The Solution

Based on the condition and age of the building, we began with preparing documents which assessed relevant codes needed to be in place for the proposed upgrades. JH team developed specific MEP measures such as replacement of the existing electrical switchboard, addition of pumping systems, alterations to the existing sanitary waste distribution, and domestic water piping upgrades, and new means of cost-effective ventilation for general spaces and the electrical service room.
