Puretech Engineering
Puretech Engineering is a Singapore mechanical and electrical contractor established in 1995, wiring rail depots, airport terminals, shipyards and commercial buildings. Its current book spans four LTA rail contracts — Kim Chuan Depot, Hume Station, the Sengkang-Punggol LRT depot and Tengah Depot — plus the Shaw Tower redevelopment and the Mandai Lake Road resort development, and it fabricates switchboards and control panels rated to 22kV.
Puretech Engineering wires the infrastructure Singapore runs on — MRT depots, airport baggage systems, shipyard substations — and its current order book is dominated by exactly that: four Land Transport Authority rail contracts, the electrical and ELV package for the 32-storey Shaw Tower redevelopment, and the resort development at Mandai Lake Road. Behind the site work sits a panel shop that builds switchboards rated to 22kV, and an electrical registration graded L6 — the top of the six-grade scale — on the government's contractors registry listing.

The work Singapore runs on
Puretech Engineering describes itself as a one-stop mechanical and electrical solution provider, and the service list bears that out. On the electrical side: medium- and low-voltage installation, extra-low-voltage systems, security surveillance, carpark and visitor systems, and electrical and instrument works. On the mechanical side: air-conditioning and mechanical ventilation, HVAC, air-con ducting, mechanical piping, conveyor systems, and plumbing and sanitary works. Fire protection and building automation round out the set.
The distinguishing line in the catalogue is fabrication: electrical switchboards and control panels rated for high-tension supply up to 22kV. That is not a trade every M&E subcontractor carries. It showed up most visibly between 2014 and 2016, when the company fabricated HVAC control panels and motor control centre and unit control panels in five batches for the Yamal LNG project — panel-shop work feeding one of the largest gas developments of the decade.
Four depots and a rainforest resort
The current project references read like a map of Singapore's less photographed construction sites. Four of them are Land Transport Authority contracts: supply and installation of electrical services for the Kim Chuan Depot extension serving Circle Line 6 (Contract 832D), M&E works for Hume Station (Contract C9358), design and build of M&E services for the Sengkang–Punggol LRT depot expansion (Contract 810G), and electrical services for Tengah Depot (Contract J175A). Rail depots are dense, demanding M&E environments — traction-adjacent power, workshops, stabling yards — and Puretech has made them a speciality.
The rest of the current book is more visible. The company holds the electrical and ELV works for the Shaw Tower redevelopment, a 32-storey office building at Beach Road, and two packages at Mandai Lake Road: electrical works for the East Arrival Node — commercial blocks, a basement transportation hub, an animal holding and breeding facility and two indoor attractions — and for the five-storey hotel and tree houses with restaurants, wellness centre and nature conservation centre being built into the same precinct.
A decade inside the Tuas shipyard
From 2014 to 2019 the past-project list is anchored in one place: the new shipyard at Tuas South. Puretech carried out electrical works for Jurong Shipyard's jack-up leg facilities and Central Hull Workshop, the 22kV substation and the proposed docks, wharves, quays and piers of the yard's Phase 2, and — in Phase 3A — the high-tension and low-tension network distribution, security systems and the electrical fit-out of a ten-block industrial development of warehouses, workshops and ancillary buildings. It wired a 600-ton crane, installed the telephone and network system for the Sembcorp Marine integrated yard, and delivered the M&E works for the yard's corporate office blocks and multi-storey carpark.
That is shipyard-grade electrical work — heavy switchgear, long HT runs, marine industrial loads — performed repeatedly for the same customer over six years, which is its own kind of reference.
Airports, tunnels and hospital wards
The infrastructure record beyond rail depots is broad. At Changi Airport the company worked across Terminals 3 and 4 between 2014 and 2018: electrical works in the T3 server room, electrical and CCTV works on the T4 baggage handling system conveyors, CAT6A and fibre-optic structured cabling, and electrical installation for T3's baggage systems. On the rail network it replaced water-handling equipment across the Circle Line, installed electrical services at Mandai Depot, and laid earth cable in the NS3 North–South transmission cable tunnel. The buildings list runs from Yishun Community Hospital and Tan Tock Seng Hospital panel works to Temasek Polytechnic, landscaping works at Nanyang Technological University's Yunnan Garden, and high-tension cable laying at GlobalFoundries in Woodlands Industrial Park D.
The pattern across all of it is consistent: Puretech is rarely the name on the hoarding, and almost always the contractor pulling the cable behind it.
The registrations behind the tenders
Public-sector M&E work is gated by the Building and Construction Authority's contractors registry, and Puretech's standing there is documented in the government's July 2023 listing of registered contractors: electrical engineering (ME05) and integrated building services (ME15) both at grade L6, the highest of the six grades in the mechanical and electrical series; air-conditioning, refrigeration and ventilation works (ME01) at L4; building automation, industrial and process control systems (ME02) and mechanical engineering (ME11) at L3; general building (CW01) at C3; and the supply workhead for electrical and electronic materials, products and components (SY05) at L5.
The safety and quality file is current-generation: the company displays SOCOTEC certification to ISO 9001, ISO 14001 and ISO 45001 under Singapore Accreditation Council accreditation, holds bizSAFE Star, and shows the WSH Advocate mark and the WSH Awards CARE 2023 emblem among its credentials. The firm itself is older than most of its registrations: established as Puretech Electrical Engineering Services in May 1995, it incorporated as Puretech Engineering Pte Ltd on 18 April 2001 and operates from UB.One on Ubi Avenue 4.
