Complete HVAC System Renewal

Comprehensive Replacement of Main Air Conditioning System for Enhanced Efficiency

Work Completed

This project required the full replacement of the sites base building main air conditioning system.

All redundant plant and equipment was decommissioned and demolished with identified asbestos containing materials removed via a specialist removalist. The existing plantroom was emptied, prepared and patched as required ready for the new plant and equipment along with required penetrations undertaken.

Two new  Temperzone split ducted HVAC units were engineered and procured to meet project requirements. The new fan coil units were lifted to the second storey plantroom while the condensers were crane lifted to the roof. A full new sheetmetal plantroom ductwork system was installed to connect the new units to the existing ductwork system within the plantrooms walls and floor. New refrigeration and electrical components were installed to complete the unit connections in preparation for service. A new wall split system air conditioning unit was also installed within the lunchroom for comfort cooling as part of the project.

A new mechanical services switchboard was designed, manufactured, installed and commissioned to power and controls the new and retained equipment via a new Direct Digital Control (DDC) system along with remote monitoring system.

The new ductwork and plantroom were painted to complete the project along with new general and emergency lighting within the plenum and plantroom.

Testing, commission and air balancing of the system were carried out to complete the project and leave in full automatic operation.

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.
