STEC is proud to win the WSH Silver Performance award in the Silver category for the fourth consecutive year. This award recognizes the consistent effort that we have made in implementing robust WSH strategies to keep our employees safe and healthy.
STEC is also the recipient of 5 SHARP awards for the excellent safety performance of our ongoing projects in 2022. These projects are LTA Jurong Region Line J102; LTA Thomson-East Coast Line T305; LTA T316; LTA North-South Corridor N109A; and PUB Deep Tunnel Sewerage System Phase 2 T11. STEC has obtained WSH SHARP Awards for eight years straight.
STEC has been ranked among Singapore's Best Employers 2022 for the third consecutive year, based on a study by The Straits Times and Statista. Over 17,000 respondents participated in the survey that evaluated more than 1,700 employers with at least 200 employees.
We are ranked 4th in the construction category and 69th overall, up from 95th in the previous year. "Employees are essential to our growth, in good times and bad. Hence, we make it a point to reward and invest in them," says Mr. Khor Eng Leong, Managing Director of STEC.
The ranking demonstrates the effort and progress that STEC has made to better support its staff, particularly in diversity, career advancement opportunities, and employees' well-being. Some initiatives we have rolled out include gender-blind recruitment, a mentorship program, and physical and mental health resources.
STEC is delighted to be among the 47 companies and individuals who received the 2022 Land Transport Excellence Award (LTEA) for their contributions to building a people-centered land transport system in Singapore. We were named the Best Managed Rail/Road Infrastructure Project Partner in recognition of our work on the tunnels between Woodlands Station and Woodlands Avenue 12 for the fully underground Thomson-East Coast Line.
The project, which includes ten tunnel drives with five TBMs, was inherently challenging as it crossed below major roads and was close to residential buildings. Through a combination of innovative engineering solutions, STEC not only ensured the safe completion of works and improved efficiency but also significantly reduced environmental impact.
STEC previously won the LTEA Best Project Partner in 2019 for its excellent performance in the construction of Gul Circle Station as part of the East-West Line.
Funan underground pedestrian link (UPL) is officially open to the public on 21 December 2021. The tunnel links the Basement 2 of Funan mall to City Hall MRT station and surrounding shopping centers including The Adelphi, Capitol Piazza and Raffles City.
Built by STEC, the 108-meter long and 6-meter wide linkway provides a convenient and sheltered journey. Shoppers can easily move between destinations in the city center without having to walk outside. The tunnel includes provisions for future connection with adjacent buildings such as Peninsula Plaza and St. Andrew’s Cathedral.
The underground link will also serve as a place to display works by various local artists. From 14 January to 13 February 2022, visitors will be able to view artworks showcased inside the UPL as part of Singapore Art Week 2022.
LTA has awarded STEC - LT Sambo Joint Venture (STEC-Sambo JV) with Contract CR102 to design and build tunnels between Aviation Park Station and Changi East Depot. A total of five tunnels with an inner diameter of 6.3 meters and a combined length of 6 kilometers will be constructed using four Earth Pressure Balance shield machines.
STEC-Sambo JV will execute the project according to aviation height restrictions due to its proximity to Changi Airport. With a construction period of eight years, the works are scheduled for completion in December 2029.
Contract CR102 is a part of Cross Island Line Phase 1 (CRL1). The 29km-long MRT line which consists of 12 stations will serve over 100,000 households. The Cross Island Line is the eighth MRT line in Singapore.

TWRP is a key element of DTSS Phase 2 which advances Singapore's water sustainability. The plant will treat industrial and domestic used water from the western half of Singapore which will be further purified for reuse. With a treatment capacity of 800,000 cubic meters per day, Tuas WRP will be the largest facility of its kind in the world. Construction works are set to begin in July 2021 and are due to be completed in 2024.
The successful completion of Funan Underground Pedestrian Linkway (UPL) project marks STEC Singapore's entry into a new market. As a leader and innovator in underground space development, STEC is at the forefront in introducing new underground construction technologies.
Funan UPL is STEC Singapore's first Rectangular Pipe Jacking Machine (RPJM) project and first commercial project in which RPJM, a less disruptive and more environmentally-friendly methodology, is adopted for the construction of underground pedestrian link. The project comprises the construction of a 108m tunnel consisting of 68 rectangular segments which links Funan Mall to Capitol Piazza. Upon completion, the public can directly travel from City Hall MRT Station to Funan Mall.
The project developer of Funan UPL is CapitaLand and the main contractor is Woh Hup - Obayashi Joint Venture.
