Erection over live roads and terminals
Large prefabricated pieces with bolted connections to shorten closures and night works.

Industries · Public infrastructure
Multi-storey car parks, pedestrian bridges, port and terminal sheds, transport canopies and public buildings. Structures for contractors and public owners who need documented quality, safe erection over live traffic and a programme that holds.
Infrastructure in Thailand

Thailand keeps investing in transport and public facilities: rail and mass-transit stations, port expansion at Laem Chabang, highway and city footbridges, park-and-ride car parks and public buildings across the provinces, many delivered by contractors under public tenders.
These projects are built next to live roads, rail lines and terminals. Prefabricated steel reduces work at height and over traffic, while documented quality, inspection records and clear method statements are what public owners and supervisors expect.
Your challenges, our answers
Large prefabricated pieces with bolted connections to shorten closures and night works.
Drawings, calculations, ITP and material certificates prepared for consultant review.
ISO 12944 C4–C5 systems or galvanising for bridges, port sheds and canopies.
Long-span steel decks that maximise parking bays and speed construction.
Fire protection to the required rating and details coordinated with escape routes.
Fabrication reserved at order and staged deliveries to match contract milestones.
What we build
Steel-framed car parks with composite or precast decks.
Truss and girder footbridges over roads, canals and rail.
Transit sheds, container freight stations and terminal canopies.
Offices, halls, markets and service centres for public owners.
Bus terminals, station roofs and covered walkways.
Pump stations, substations and treatment-plant buildings.
Inside the structure
Typical design choices. Every project is engineered to its own brief, site and standards.
| Design item | Typical approach |
|---|---|
| Car parks | Long-span steel frames with composite or precast decks |
| Footbridges | Truss or girder spans with deflection and vibration checks for pedestrians |
| Port sheds | Wide spans for cargo handling, coastal coatings |
| Coating | ISO 12944 C4–C5 systems or hot-dip galvanising |
| Wind and seismic | DPT 1311-50 and DPT 1301/1302-61 for the site |
| Fire protection | Intumescent paint where a rating is required |
| Erection | Bolted connections and large modules to reduce closures |
Most of the work happens in our factory, not over traffic.
ITP, certificates and inspection records for supervisors.
Systems specified for exposure and maintenance intervals.
Car parks, bridges, sheds and canopies from one factory.

FAQ
Yes. Omakase Car Park Building D in Thailand, footbridges and a port structure in Singapore, and a bridge in Vietnam are among our projects.
Yes. We supply the steel package with drawings, calculations and quality documents for the consultant's review.
ISO 12944 C4–C5 systems or hot-dip galvanising, chosen for the exposure and maintenance plan.
We fabricate large pieces with bolted connections, so erection needs shorter road or rail closures.
