Why the Contractor Choice Matters
The contractor you appoint shapes how your factory project goes: the build quality, how problems get handled, and whether the final cost matches the quotation.
Price matters, but it’s only one of several checks. You know how two quotations can look close on price? The difference often shows up later, because Industrial Malaysia’s guide points out that no one may occupy a building until its Certificate of Completion and Compliance (CCC) is obtained, and someone has to own that process.
If you’re planning factory construction on your own land in Selangor, here’s how to choose a factory contractor. We’ll go through five checks, then the contract terms to read before you sign.
Check 1: Registration and Company Record
Construction contractors in Malaysia generally need to be registered with the Construction Industry Development Board (CIDB), and the registration grade limits the size of contract they can take on. Ask to see the current certificate, known as the PPK (Perakuan Pendaftaran Kontraktor), and check the grade suits your project size.
According to MISHU’s guide to CIDB registration, the usual project limits for the top grades are:
- G5: up to RM5 million
- G6: up to RM10 million
- G7: no limit
MISHU also notes that this table is a simplification, so treat it as a general guide and ask the contractor to confirm the grade covers your total contract sum.
Then check the company itself. How long has it been operating, what is its registration number, and who runs it? These questions matter for any factory contractor in Malaysia, big or small.
For reference, we’re Factory Builder Malaysia, the factory building arm of QDB Ventures Sdn Bhd (588367-M), a Cheras-based contractor incorporated in 2002.
Check 2: Completed Factories You Can See
Ask for completed factory projects, not just any buildings. Factories have their own demands: wide spans, heavy floors, loading bays, machinery services. A contractor who mainly builds houses or shops may not know them.
Visit if you can. Here’s what to look at and ask:
- The floor: look for cracks, especially where forklifts and machinery run.
- The roof and gutters: look for stains or signs of leaks.
- The owner: ask how the project went and how problems were handled.
- The paperwork: ask how long the CCC took after the building was finished, since the owner can’t move in without it.
Our completed factories are in Klang, Cheras and Balakong. You can ask about viewing them on our projects page.
Check 3: Who Leads the Engineering
Find out who will answer engineering questions. In a factory project, floor loading, power supply, drainage and structure need decisions early. A team that includes engineers, project managers and quantity surveyors can answer them without waiting on outside parties.
Ask for names, not just job titles. The Board of Engineers Malaysia (BEM) keeps the official register of Professional Engineers with Practising Certificate (PEPC), so you can check that the engineer on your project is genuinely registered.
Check 4: Who Handles Consultants and Submissions
Ask directly: who appoints the architect and engineers, who prepares and submits the plans, and who deals with TNB, Air Selangor, Indah Water and Bomba? The answers should be in the quotation. If they are not, ask for them in writing.
Four questions are worth putting to every contractor:
- Who appoints the architect and engineers?
- Who prepares and submits the plans?
- Who deals with TNB, Air Selangor, Indah Water and Bomba?
- Who acts as the Principal Submitting Person (PSP) for the CCC?
The last one is easy to miss. The Institution of Planners Malaysia (IPM) explains that the PSP is a qualified person, such as an architect or a PEPC, who is responsible for issuing the CCC.
The workload is real. FactoryHub’s 2026 guide says the CCC rests on 21 stage certificates (Forms G1 to G21), and eight of them need a clearance letter from an agency such as Bomba, DOSH or TNB.

Contract Terms to Review
Before signing, read these six terms line by line. They set out who pays what, when and what happens if things go wrong in your factory construction contract.
| Term | What to check |
|---|---|
| Scope | Matches the quotation’s inclusions, exclusions and responsibilities |
| Progress claims | Payments tied to measurable work done |
| Retention | How much is held back, and when it is released |
| Liquidated damages | Sum per day or week of delay, and how delay is assessed |
| Variations | How changes are priced and approved in writing |
| Defects liability | How long the period is and what it covers |
On retention, a 2024 PAM (Malaysian Institute of Architects) practice note puts the figure under the PAM contracts at 5% of the contract sum. The Legal 500’s 2026 Malaysia construction guide adds that retention is commonly released in two stages: half at practical completion, the other half after the defects liability period ends.
Our guide on how progress payments work explains claims, retention and liquidated damages in more detail. For what happens after completion, see after factory handover.
Get the answers in writing
Verbal assurances are easy to give and hard to enforce. Anything important should be in the quotation or the contract.
Check 5: Communication
Before you sign, agree who your main contact is, how often you’ll get updates and how decisions are recorded. Poor communication is one of the most common complaints owners have about contractors, and it is easy to check upfront.
Ask these three things:
- Who is your single point of contact?
- How often will you get progress updates, and in what form?
- How are changes and decisions recorded?
The last one has legal weight. Malaysia’s Construction Industry Payment and Adjudication Act 2012 (CIPAA) gives a fast route for payment disputes, and a PAM briefing on the Act lists a written contract, or evidence of one, among the first things to establish before bringing a claim. Written records protect you if a payment disagreement ever arises.
A Simple Shortlist Test
Here’s how to choose a factory contractor in one glance. A contractor worth shortlisting should be able to:
- Show you completed factories
- Explain who leads the engineering
- Give you a quotation with clear inclusions, exclusions and responsibilities
- Explain the contract terms plainly
If any of these is missing, ask why. A good answer is a good sign, and a vague one tells you something too.
