Who We Are — And Why We're Writing This

We're Wong Lye Pte Ltd (UEN 201404127Z), a BCA General Builder Class 2 licensed contractor. We've been doing structural work since 2014 — started with warehouse builds, moved into landed homes around 2017. We handle A&A, reconstruction, piling, and structural works for landed properties in Singapore.

We get asked fairly often about other contractors in the industry, including Joo Lee Engineering Pte Ltd. Homeowners searching for builders sometimes come across multiple names and want to know the difference. So here's what we know — not as a competitor assessment, but as context for what kind of contractor you might actually need for your landed project.

What We Know About Joo Lee Engineering

Joo Lee Engineering Pte Ltd is a registered contractor in Singapore. From what we understand through industry channels, they operate in the engineering and construction space. We haven't worked directly with them, so we can't speak to their specific project portfolio or internal practices.

What we can tell you is this: when you're searching for a contractor by name, the more important question isn't "who are they?" — it's "what kind of work do they do, and does that match what I actually need?"

In our experience, homeowners often confuse three different types of contractors:

• Structural engineers — professionals who design and certify structural integrity, often acting as the Qualified Person (QP) for BCA submissions
• General builders — licensed contractors (like us) who execute structural works, A&A, rebuilds, and reconstruction
• Renovation contractors — typically HDB-licensed or unlicensed firms doing interior fit-outs, finishes, and non-structural alterations

These roles overlap sometimes, but they're not interchangeable. A structural engineer might not have a builder's licence. A builder might not have in-house QP capability. A renovation contractor usually can't touch load-bearing walls or do piling.

What You Actually Need for a Landed Build or A&A

If you're doing anything structural on a landed property — knocking down walls, adding a storey, extending a room, underpinning, piling — you need two things:

1. A Qualified Person (QP) — usually a Professional Engineer (PE) or architect registered with BCA. They design the structural works and submit plans to BCA. They're legally responsible for certifying that the design is safe.

2. A licensed general builder — someone with a BCA General Builder licence (we're GB2, which is one level below the top GB1 tier). The builder executes the works according to the QP's drawings and specifications.

On smaller projects, these can be two separate parties. On larger or more complex projects, it's often easier when the builder has an in-house QP (we do). That way, design and buildability are considered together from day one, and there's no finger-pointing if something doesn't work on-site.

We've had clients come to us after getting quotes from three or four different contractors, only to realise halfway through that one was a renovation contractor (no building licence), another was a engineering consultancy (no build team), and the third was a builder but had to subcontract the QP submission separately.

It's not wrong to split the roles — but you need to know what you're coordinating.

When Homeowners Search for Contractors by Name

Here's a pattern we see often: a homeowner hears a company name from a neighbour, a forum, or a Google search. They reach out, get a quote, maybe even sign a contract — then discover later that the scope doesn't match what they thought they were getting.

For example:

• Neighbour recommends "the contractor who did my kitchen" — but your project involves hacking a load-bearing wall, which needs a builder's licence and PE certification, not just a reno contractor.
• You find a company online that does "engineering" — but they're a consultancy, not a builder. They'll draw the plans, but you still need to hire someone else to swing the hammer.
• You get a quote that seems too cheap — because it doesn't include QP submission fees, BCA compliance, or piling works that your actual site will require.

We've seen all of this happen. And we've been called in mid-project to fix it more than once.

Our advice: before you hire anyone by name, ask these questions:

• What is your BCA licence class? (If they don't have one, they can't do structural works legally.)
• Do you have an in-house QP, or do you subcontract submissions?
• What exactly is included in your quote? (QP fees? BCA submission? Piling? Hoarding? Site supervision?)
• Can I see a similar project you've completed, with the same scope?

What We Do — And What We Don't

To be clear about our own scope:

We do structural works for landed homes. A&A (additions and alterations), reconstruction, piling, underpinning, steel frame fabrication, solar panel mounting structures. We have an in-house QP (architect), so we handle URA and BCA submissions as part of the build. We've done this for over 15 years, starting in commercial/industrial and moving into landed residential carefully and selectively.

We don't do HDB flats (different licence). We don't do pure interior renovation — that's our sister company Larry Contractors (contractors.com.sg), which has the HDB renovation licence. And we don't take on projects where the homeowner just wants the cheapest quote — we'd rather be accurate upfront than cheap now and expensive later.

If your project involves knocking down walls, adding storeys, digging for basements, or anything that changes the structure — talk to us. If it's repainting, kitchen cabinets, or flooring — talk to Larry. If it's something in between, we'll tell you honestly who should handle which part.

Why We Write Articles Like This

We started writing about building topics a few years ago because we got tired of seeing homeowners make expensive mistakes based on bad advice.

"My neighbour did a basement, so I can too." (Neighbour's soil type was different. Or they did it illegally and just haven't been caught yet.)

"This contractor quoted half what you did." (Because they left out the piling, the QP, and the BCA submission fees.)

"I thought engineering meant they'd build it too." (Nope — engineering consultancy ≠ general builder.)

We'd rather you get accurate information before you sign a contract, even if you don't end up hiring us. Bad builds hurt everyone — the homeowner, the industry, and the next builder who has to fix it.

So if you're searching for contractors by name — whether it's Joo Lee Engineering, us, or anyone else — make sure you're comparing apples to apples. Check the licence. Ask about scope. Get it in writing.

Frequently Asked Questions

Is Joo Lee Engineering the same as Wong Lye?

No. We're Wong Lye Pte Ltd (UEN 201404127Z), a BCA General Builder Class 2 licensed contractor specialising in structural works for landed homes. Joo Lee Engineering Pte Ltd is a separate company. We haven't worked with them, so we can't speak to their specific scope or services.

Do I need a structural engineer or a general builder for my landed A&A?

You need both — or you need a general builder with an in-house Qualified Person (QP). The QP designs and certifies the structural works for BCA. The builder executes the works on-site. We have both in-house, which simplifies coordination. If you hire them separately, just make sure the builder is BCA-licensed and the QP is a registered PE or architect.

Can a renovation contractor do structural works?

No. Structural works — anything involving load-bearing walls, beams, columns, foundations, piling — require a BCA General Builder licence. Renovation contractors (even HDB-licensed ones) can't legally do structural works. If someone offers to "hack the wall" without a builder's licence and QP certification, walk away. It's illegal and dangerous.

What should I ask before hiring any contractor for a landed build?

Ask for their BCA licence class, whether they have an in-house QP, what's included in the quote (QP fees, submissions, piling, hoarding, supervision), and whether they can show you a completed project with similar scope. If they dodge any of these questions, that's a red flag. We answer all of them upfront, in writing, before we even start quoting.

Why do your quotes include things other contractors leave out?

Because we'd rather be accurate than cheap. Our quotes include QP submissions, BCA compliance, piling (if required), hoarding, site supervision, and everything else that's actually needed to complete the job legally and safely. If another quote is much lower, check what's missing. We've been called in mid-project too many times to fix "cheap" quotes that turned expensive.
