PROJECT 25
As with any large-scale, high-rise residential development, the wet services installation presented several logistical and coordination challenges that required careful planning and proactive problem-solving.

• In addition, a rainwater harvesting system has been incorporated to supplement the irrigation water supply. Harvested rainwater is used alongside borehole water for landscape maintenance, reducing demand on municipal infrastructure and promoting responsible water stewardship. This integrated approach not only lowers operating costs but also contributes to the conservation of water resources.
• Better resident experience through reliable water pressure, hotwater availability and uninterrupted service delivery.
• Future-ready infrastructure, designed to accommodate modern water management requirements and increasing resource constraints.
The challenges of the project The greatest challenge was not the installation itself, but co-ordinating multiple stakeholders, services, deliveries and commissioning activities within a fast-paced construction programme. Success depended on detailed planning, close collaboration between trades and maintaining flexibility when unexpected delays arose.
One of the most significant challenges involved the installation of the centralised hot-water plants. The project ' s Alliance heat pumps and heat accumulator storage vessels were located on the rooftop, making timely co-ordination with the site ' s tower crane essential. Any delay in securing crane access could have affected multiple trades and the overall programme. Compounding this challenge were supply chain uncertainties, including delays in the arrival of the imported heat pumps because of global geopolitical tensions. This created additional pressure to ensure the equipment was delivered, lifted and installed within a narrow construction window.
Another challenge was the delayed installation of the municipal water connection and power supply, which impacted the commissioning phase of the project. Without a live water supply from the local authority, the team was unable to fully commission the water storage tanks, booster pump sets and associated water reticulation systems according to the original schedule. This resulted in a compressed testing and commissioning period toward project completion.
In addition, the concealed nature of the apartment water reticulation introduced co-ordination challenges with other subcontractors. The hot- and cold-water pipework had been chased into walls to achieve a clean architectural finish; however, subsequent construction activities occasionally resulted in other trades inadvertently drilling into or damaging the concealed pipework.
