Integrated HVAC Upgrade

Engaged for a major HVAC upgrade, we collaborated with the client’s team for detailed planning and execution. Temporary systems ensured uninterrupted operation during the complex process of splitting and upgrading the facility’s HVAC system. Comprehensive works included new installations, system enhancements, and integrating advanced control systems, ensuring efficiency and modernisation.

Efficient AC Upgrade

The existing main air conditioning system serving this facility was at the end of its maintainable life span. With this in mind and additional future load increases planned for the site we were engaged to provide both design and construction services to provide a solution for the upgrade of the aging plant along with augmenting the existing supplementary units into the new system.

Standby Generator Plant (SGP) Capacity Enhancement

Our team expertly executed the Standby Generator Plant (SGP) Upgrade, significantly boosting power reliability and capacity. The project entailed detailed audits, temporary solutions, and a new Cummins generator installation, all within a tight space and timeframe. This upgrade exemplifies our commitment to advanced, efficient power solutions.

Complete HVAC System Renewal

This project successfully involved the full replacement of the main air conditioning system, upgrading to high-efficiency Temperzone units. Including asbestos removal, new ductwork, and a custom mechanical services switchboard, the project concluded with system testing and balancing, exemplifying our expertise in modern HVAC solutions.

Ductwork Upgrade

This project skillfully enhanced the ductwork system for a data floor, integrating new outlets for equipment suites. Our proposal included ductwork redesign, dropper, damper, and grille installation, with meticulous air and temperature testing for optimal airflow, demonstrating our commitment to innovative and efficient air distribution solutions.

Switchboard and Electrical Infrastructure Transformation

This major project involved upgrading electrical infrastructure, including a new main switchroom and switchboard, to accommodate increased loads from new equipment. Work included building a fire-rated switchroom, excavating for conduits, and coordinating with supply authorities, culminating in a seamless integration of new emergency lighting and generator systems.
