The EPC work sequence, phase by phase.
Each phase below has its own page setting out the work we do, the documents you receive at the end of it, the typical duration, and the codes it is built against.
Work sequence
-
Planning & Feasibility
Testing whether the project is viable on the land, budget, and schedule available.
-
Design & Engineering
Turning the production requirement into buildable drawings, calculations, and specifications.
-
Permitting & Compliance
Securing the building approval, environmental documents, and technical clearances the project needs.
-
Procurement
Tendering work packages, locking vendors, and ordering long-lead items on time.
-
Civil & Structural Works
Preparing the site, placing foundations, and erecting the concrete and steel structure.
-
Architecture & Enclosure
Closing the building: roof, walls, facade, floors, industrial doors, and support spaces.
-
MEP & Utilities
Installing power, HVAC, plumbing, fire protection, wastewater treatment, and process utilities.
-
Commissioning & Handover
Testing every system, closing defects, securing the SLF, and handing over an operational building.
Eight phases, but not eight queues.
The phase numbers show the order of responsibility, not a rigid timeline. Projects that finish on time usually do so because several phases overlap.
| Phase 02 + 03 | Design and permitting run together. The technical package the PBG needs comes out of the same detailed design process. |
|---|---|
| Phase 04 + 05 | Long-lead orders are locked while earthworks and foundations are still starting, not after the structure is up. |
| Phase 05 + 06 | The envelope starts in areas already under roof, so interior MEP work can begin earlier. |
| Phase 06 + 07 | MEP follows the enclosure sequence, on pipe rack and tray routes already coordinated back in Phase 02. |
Not every client needs all eight phases.
Some already have a design, some only need permitting closed out. We take partial scopes, with the responsibility boundary written into the contract from the start.
Discuss your scope| Phases 01–03 | Design and permitting only. You self-perform construction or tender it separately. |
|---|---|
| Phases 05–08 | Construction only, where a design already exists. We run a design review first and issue the findings in writing. |
| Phases 01–08 | Full EPC. One contract, one accountable party, from feasibility through to final handover. |
Questions we are asked
- How long does it take to build a factory from empty land?
- For a mid-scale factory or warehouse in Greater Jakarta and the surrounding industrial belt, a reasonable range is roughly 10 to 18 months from feasibility study to handover, with permitting and design running in parallel. The exact figure depends on the foundation type, the complexity of process utilities, and how quickly the local authority issues the PBG. We give a phase-by-phase schedule in Phase 01 rather than a single headline number.
- What does a factory cost per square metre?
- We do not quote a rate per square metre before seeing the project, because the range is too wide to be useful. The biggest cost drivers are the foundation type dictated by soil conditions, clear height and structural span, floor specification, electrical and HVAC capacity, wastewater treatment requirements, and how far the office areas are fitted out. In Phase 01 we give an estimate accurate to roughly ±25 per cent, tightening to around ±10 per cent once detailed engineering and the bill of quantities are complete.
- Does TCC handle the PBG and SLF?
- Yes. Permitting is Phase 03 of our work sequence, covering the PBG building approval, UKL-UPL or AMDAL environmental documents, traffic impact analysis where required, and other technical clearances. The Certificate of Fitness for Occupancy is closed out in Phase 08 together with statutory safety inspections, so the building is legally operable at handover.
- Which areas does TCC serve?
- We are based in Jakarta and work primarily across Greater Jakarta and the surrounding industrial belt: Bekasi, Cikarang, Karawang, Purwakarta, Subang, Tangerang, and Serang. For projects outside that area we assess viability case by case, based on project scale and local supply chain availability.
- Can TCC take on only part of the sequence?
- Yes. The most common partial scopes are design and permitting only, covering Phases 01 to 03, or construction only, covering Phases 05 to 08 where a design already exists. For construction-only packages we run a design review first and issue the findings in writing before agreeing a price and programme.
