From pasting stickers on safety helmets, to identifying the skill set of construction workers, to setting up on-site training schools for hands-on learning - these are some ideas the Land Transport Authority (LTA) is hoping its contractors can learn from one another.

Yesterday, the LTA launched the 43-page Workplace Safety, Health and Environmental Good Practices Handbook, compiling 30 innovative solutions to challenges faced at its worksites. Contractors can download an e-copy of the handbook with a QR code, which will be printed on biannual safety newsletters circulated to contractors.

The good practices are drawn from LTA's contractors, who had "gone the extra mile to achieve safety and environmental excellence" for its projects, it said.

LTA chairman Alan Chan, who announced the book's launch at the authority's 19th Annual Safety Award Convention, urged contractors to implement the best practices to enhance safety standards.

Besides boosting safety, solutions to minimise environmental impact in LTA projects, such as tunnelling for a new MRT line, are also featured in the book.

One example is a retractable noise enclosure created by Daewoo Engineering & Construction for the construction of Thomson-East Coast Line's Stevens station and tunnels. The enclosure is installed at the opening of the tunnel shaft - which is where the tunnel-boring machine is lowered into and launched from - and helps to reduce noise emission. As the cover is retractable, the machine can be easily lifted out and reconfigured without the need to disassemble the noise enclosure.

Associate Professor Goh Yang Miang of the National University of Singapore's Department of Building said of the LTA's handbook: "It is a good reference and benchmark, which can possibly influence the actual practices at LTA worksites."

The key challenge is the next step - "to motivate contractors to adopt these practices", said Prof Goh.
