Completed Project Highlight ICHOR UNITY Ichor Unity is a greenfield project involving the design and construction of a new manufacturing facility for Ichor Systems. The facility comprises 11,000 sf of ISO 5 cleanroom, 14,000 sf of ISO 7 cleanroom, 10,000 sf of office space, 6,000 sf of cafeteria area, and 80,000 sf of CNC machining space, supporting advanced precision manufacturing. The project scope included full M&E system integration and utility infrastructure, featuring a 400 RT water-cooled chiller system, 25 m²/hr ultra-pure water system (18 mega-ohm resistivity), 40 m³/hr effluent treatment system, 12,000 cfm air scrubber, and an 11 kV power upgrade providing 3,745 kW. The facility also includes a fully automated electro-polishing line with a capacity of 7,500 parts per day, supported by bulk gas systems with 10,000 L nitrogen and 5,000 L argon tanks. Delivered to meet stringent cleanroom and process requirements, Ichor Unity stands as a state-of-the-art facility that reflects AlfaTech’s commitment to engineering excellence, sustainability, and precision-built industrial environments.

Public Utilities Board (PUB) Waterworks is a government project that spans three different locations and involves addition, alteration, and improvement works across twelve operational buildings. This completed project includes the demolition and construction of new office spaces, alteration and upgrading of toilets and pantries, and underground piping works for plumbing and sanitary systems. It also covers the overhaul of the ACMV system, including the design and installation of new VRV and FCU units, as well as the upgrading of the electrical distribution network to enhance energy efficiency and system reliability. This project presents a high level of logistical and coordination complexity, as all works are carried out within live operational environments. Close collaboration and careful planning are essential to minimise disruption to the daily operations of the various water treatment plants, ensuring smooth progress while maintaining safety and functionality throughout.
