Upper House Residences: 500 days on site without a lost-time injury

On 16 July 2026, the team building Upper House Residences on Wireless Road marked 500 consecutive days with zero lost-time injuries, and City Dynamic presented a Zero LTI Award to the main contractor, Stonehenge International. For a buyer, a disciplined site is a fair sign of a disciplined build.

On 16 July 2026, the team building Upper House Residences on Wireless Road marked 500 consecutive days on site without a single lost-time injury. City Dynamic, the City Realty and Swire Properties delivery team, presented a Zero LTI Award to the main contractor, Stonehenge International. It is a quiet milestone, and a telling one.

What the milestone is

A lost-time injury is a workplace injury serious enough to keep a worker off the job. Five hundred clear days, on a deep and complex site in the middle of the city, is an unusual record. It does not happen by luck. It is the result of a site run to a standard held every day, by everyone on it, from the developer down to the newest worker.

Why it matters to a buyer

A branded residence is a promise about how a building is made and kept, not only how it looks. The clearest early evidence a buyer has of that promise is how the site itself is run. A disciplined, safe site is a fair proxy for a disciplined build: careful sequencing, proper supervision, and a contractor that measures what it does. It is the same discipline that later shows in the finish of a home and the way the building is maintained.

A lost-time injury is a workplace injury serious enough to keep a worker off the job. Five hundred clear days is an unusual safety record on a major Bangkok tower.
