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 passed 500 days in a row on site without a single injury serious enough to keep anyone off work. City Dynamic, the City Realty and Swire Properties team, gave its Zero LTI Award to the main contractor, Stonehenge International. It is a quiet milestone, and a telling one.

500
days in a row, no lost-time injuryA lost-time injury is one serious enough to keep a worker off the job. Five hundred clear days on a deep site in the middle of the city is an unusual record.

Why this matters to a buyer

A branded residence is a promise about how a building is made and kept, not only how it looks. A safe site is fair evidence of a careful build.

Five hundred clear days does not happen by luck. It is a standard held every day, by everyone on site.

Read the full explanation

The clearest early evidence a buyer has of that promise is how the site itself is run. A disciplined, safe site points to 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 in how the building is maintained.

Who is building it

Stonehenge International is main contractor, with RITTA on site, for a development by Swire Properties and City Realty.

Common questions

What is the 500-day zero-injury milestone at Upper House Residences?

On 16 July 2026, City Dynamic (the City Realty and Swire Properties delivery team) presented a Zero LTI Award to the main contractor, Stonehenge International, marking 500 consecutive days on the Upper House Residences site without a single lost-time injury. 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.

Does this change the completion date?

No. This is a construction-safety record, not a handover announcement. It signals a disciplined, well-run site rather than a new timeline. Embark confirms the current construction status and expected handover privately, at inquiry.

Who is building Upper House Residences?

The main contractor is Stonehenge International Public Company Limited, with RITTA also on site. The development is by Swire Properties and City Realty, delivered through their City Dynamic team. Upper House Residences is the branded House, and The Wireless Residences by Upper House is the second House on the same Wireless Road development.
