MCI Construction — Post-Tensioning, Bearings & Structural Health Monitoring
MCI Construction
MCI Construction — a division of PT. Mills & Mines International

We tension the structures a nation stands on

Post-tensioning, seismic protection, cable systems and structural monitoring — engineered from the tendon up, installed by our own crews, and proven on bridges, rail and high-rise buildings across Indonesia.

Construction Services

Eight disciplines, one crew

Named for the cedar — strength, durability, magnificence. We carry a project’s most force-critical work: the tendons, anchors, cables and devices that decide whether a structure merely stands or endures.

01Post-Tensioning

Slab, beam and bridge tendons for new structures; external tendons that return existing ones to full working strength.

02Bearings & Joints

Bridge bearings and expansion joints installed and aligned so the deck moves exactly as designed — and nowhere else.

03Ground Anchors & Soil Nailing

Turnkey anchorage from design to proof load — excavations, slopes and uplift, protected against corrosion for the duration.

04Tie-Back Systems

Lateral restraint for retaining walls, diaphragm walls and sheet piling — temporary or permanent, tested anchor by anchor.

05Seismic Isolation

LRB, HDRB and friction-pendulum isolators that cut the seismic force a structure receives by 60–80 percent.

06Structural Dampers

Viscous, viscoelastic and buckling-restrained devices that turn wind and earthquake energy into heat, not damage.

07Stay-Cables

Stay-cables, hangers and tie rods installed strand by strand and tensioned to the decimal — proven at 1,196 metres on the Siak.

08Health Monitoring

SHMS sensor networks that stream a structure’s real condition to one dashboard — maintenance by data, not by guess.

Projects Highlights

Projects / 2014—2024
Siak cable-stayed bridge over the Siak river
Cable-Stay Systems
Siak Bridge, Siak Sri Indrapura

1,196 m long and 16.95 m wide on two 80 m pylons. Galvanized 15.24 mm PC strand, in cables of up to 55 strands — every single one anchored, tensioned and certified by our crews.

Stressing works in progress on the Kualanamu–Medan toll road
Stressing Works / 2014
Kualanamu–Medan Toll Road

Supervision of stressing on 25 m segmental PC-I girders with WIKA Beton — five beams per span, three tendons per beam, twelve strands per tendon. Three beams installed and stressed in two days.

Track-slab and sleeper yard for the Jakarta–Bandung high-speed rail
Rail / 2020
Jakarta–Bandung High-Speed Rail

One complete track-slab production line prepared and supplied; 100 sets of sleepers produced and delivered for the near-station segment of Southeast Asia’s first high-speed railway.

How We Deliver

Process / Quality
01
Scope & Design Review

We read the structure before we price the work — requirements reviewed against the tendon, anchorage or device scheme.

02
Engineering & Supply

Components sourced through our parent group to the specified grade — one supply chain, fully certified.

03
Installation

Our own crews, our own equipment — methods proven across bridges, rail and high-rise buildings.

04
Stressing & Supervision

Every tendon stressed to design force and documented — elongation checked, records handed over.

05
Monitoring & Handover

SHMS available through service life — the structure keeps reporting long after we leave site.
