We engineer the ground Indonesia grows on.

From commercial districts to cable-stayed bridges and toll roads, ABI plans, designs and builds with digital precision from the first survey point to the final handover.

01Services

Three disciplines, one digital thread.

All services

↗Build sequence · Bridge

From the first pile to the last light.

  1. 01/ 04Foundation

    Ground truth first

    Drone and LiDAR survey, soil investigation and bored piles. Every structure starts from data measured on site, not assumed.

  2. 02/ 04Structure

    Rise with tolerance

    Pylons, decks and frames go up against a BIM model checked daily, so clashes are solved on screen before they reach steel and concrete.

  3. 03/ 04Network

    Connect the corridor

    Stay cables, pavement, drainage and utilities tie the structure into the road network it serves, sequenced in 4D to keep traffic moving.

  4. 04/ 04Handover

    Lit, tested, delivered

    Load tests, as-built surveys and a digital twin handed to the owner, so the asset can be maintained for decades.

02By the numbers

Measured in spans, kilometres and handovers.

↗Build sequence · Toll road

From cleared ground to the first car through.

  1. 01/ 04Earthworks

    Shape the ground

    Survey stakes set the alignment, then cut and fill bring the corridor to grade, compacted and tested layer by layer.

  2. 02/ 04Base

    Build up the layers

    Aggregate base and lean concrete go down to profile, checked against the design surface by GNSS-guided machines.

  3. 03/ 04Pavement

    Pour the slabs

    Slipform pavers lay 30 cm of rigid pavement with dowelled joints, and the median barrier follows close behind.

  4. 04/ 04Operations

    Open to traffic

    Markings, signs, lighting and the toll plaza are commissioned, then the section opens and traffic starts to flow.

03Selected work

Shophouses, spans and corridors.

All projects

↗Build sequence · Shophouses

From the first footing to the first shop open.

  1. 01/ 04Foundation

    Set the footings

    Soil tests size the pad footings, and a ground beam ties them into one base for the whole row.

  2. 02/ 04Frame

    Rise floor by floor

    Columns and slabs are cast storey by storey against the BIM model, with the tower crane and formwork on a planned cycle.

  3. 03/ 04Envelope

    Close it in

    Brick infill, window frames and the roof make each unit weathertight, ready for services and finishes.

  4. 04/ 04Handover

    Lights on, shutters up

    Shop fronts, signage and street lighting are commissioned, and every unit is handed over with as-built drawings.

04Technology

The site is modelled before it is built.

  1. T01

    BIM coordination

    One federated model for structure, MEP and civil works, clash-checked before anything is fabricated.

  2. T02

    Drone & LiDAR survey

    Centimetre-level terrain and progress data, flown on a schedule instead of estimated from the ground.

  3. T03

    4D scheduling

    Programme linked to the model, so sequencing, traffic management and cash flow are planned visually.

  4. T04

    Digital twin handover

    As-built model and sensor-ready asset data delivered to the owner for decades of maintenance.
