SKK Works

What SKK Works does

SKK Works Pte Ltd is a Singapore-based civil engineering and infrastructure services contractor founded in October 2013 by Sze Koon Kiat. The company specializes in subsurface utility works, with Horizontal Directional Drilling (HDD) as its core technology — a trenchless method for installing water mains, sewer and drainage pipelines, gas lines, telecom cables, and 66kV-400kV power cables without surface disruption. Supporting services include live insertion valve installation (S-GATE DN200-300 systems), CCTV pipeline inspection using X5-HS/X5-HT4 robots for DN300-DN1000 diameters, Spiral Wound Lining sewer rehabilitation, trenching, water pipeline installation, electrical cable laying, road works, water vacuum tanker service, and an 80-ton lorry crane service. Equipment is operated in-house from an owned fleet anchored by four JVD-series HDD rigs (JVD320, JVD380, JVD420 x2, JVD500).

The company serves three primary verticals in Singapore: government utilities (anchored by Singapore's Public Utilities Board for watermain, sewer, and pumping-mains work), power and energy companies (SP Powerassets, Taihan Electric Wire for underground high-voltage cable installation), and telecommunications firms (Singtel, Starhub, TM Hub, Bluetel for telecom pipe installation and gyroscopic mapping). Revenue is project-based and contract-driven, secured through competitive tendering on multi-year framework agreements (e.g., PUB watermain contracts spanning 2015-2026) and individual project bids. The company holds ISO 9001:2015, ISO 45001:2018, bizSAFE Enterprise Level Star, and a Singapore Enterprise Medal of Honor, credentials that function as prerequisites for bidding on regulated utility work.

SKK Works operates as the core wholly-owned subsidiary of SKK Holdings Limited, a Cayman/BVI-incorporated holding company that listed on Nasdaq under ticker SKK in October 2024 following a $10 million IPO. The group also owns SKK Works M&E Pte Ltd (mechanical and electrical contracting, fully consolidated in 2023) and SKK Group Limited (BVI intermediate holding entity). In May 2026, SKK Holdings signed a Definitive Asset Purchase Agreement with Rantizo Inc for drone-related assets, signaling a tentative expansion into unmanned aerial services beyond the core civil engineering base. The Nasdaq-listed entity has experienced minimum bid price compliance issues since late 2025, resolved via share consolidation in April 2026.
