Tiong Seng

What Tiong Seng does

Tiong Seng is a Singapore-headquartered, publicly-listed construction and built environment group founded in 1959 and operating across building construction, civil engineering, property development, prefabrication, engineering works, and green technology solutions. It serves public-sector clients (LTA, BCA, HDB, JTC, MOH Holdings, NParks) through BCA A1-graded unlimited-value tenders, private developers (Capella, ParkRoyal on Pickering, NTUC FairPrice, Equinix, Resorts World Sentosa), and end-buyers via boutique residential developments in Singapore (Cairnhill 16, Sloane Court) and a residential/commercial portfolio in China's Bohai Economic Rim (Tianjin, Suzhou, Yangzhou), with a new senior-care facility (TSCC) opened in Tianjin in 2024. The Group's technology stack is anchored by Design for Manufacturing & Assembly (DfMA), Building Information Modelling (BIM) with ISO 19650 certification, and Integrated Digital Delivery (IDD), supported by in-house patented products — Lithe™ PPVC, Lithe™ PBU (using Ultra High Performance Concrete), Cobiax voided slabs (under exclusive Singapore licence), TS Sleeve grout-filled rebar splices, Modular MEP, and Mass Engineered Timber — produced at the Tiong Seng Prefab Hub (Singapore, 2012) and an automated precast plant in Malaysia.

The Group generates revenue through project-based construction contracts (one-time tender awards for building and civil engineering), per-unit property development sales (Singapore boutiques and Chinese mid-tier cities), prefab hardware sales (Lithe™ PPVC/PBU and engineered components exported from Singapore), and professional services in green materials and BCA Green Mark delivery. Pricing is tender/quote-based and not publicly disclosed. GTM is primarily enterprise field sales — competitive tender submissions for public works, negotiated Design & Build proposals for private developers — complemented by direct-to-consumer sales for property development and channel/wholly-owned subsidiary distribution for prefabricated product exports. The Group has won more than 150 awards since 2010 (including the inaugural BCA Built Environment Leadership Award in 2009, the Singapore Quality Award in 2013, and the BCA Pinnacle Built Environment Leadership Platinum Star Award in 2019) and holds ISO 9001/14001/45001/19650 and SS506 certifications alongside bizSAFE Star.

Corporate structure is led by Executive Director & CEO Pek Lian Guan (re-appointed 5 August 2025), Executive Chairman Dr Teo Ho Pin (Independent Director), Honorary Founding Chairman Pek Ah Tuan, and an extended executive team running a wholly-owned subsidiary stack comprising Tiong Seng Contractors, Tiong Seng Civil Engineering, Robin Village Development, Robin Village International, Steeltech Industries, Tiong Seng Engineering Solutions (TSES), COBIAX Asia-Pacific and AMP Systems. The Group faces an ongoing legal matter in which the High Court set aside an acquittal in a bribery case involving CEO Pek Lian Guan and Pay Teow Heng — a notable governance overhang.
