We built our first warehouse racks in 2014 because we couldn't find a contractor we trusted to do it properly. That decision changed our entire business. Neighbours saw the work, asked us to build theirs, and suddenly we were doing commercial warehouse fits full-time. Over 1,500 commercial and industrial clients later — before we ever touched a landed home — we learnt what separates contractors who last from those who don't.

If you're looking for the best warehouse contractor in Singapore, you're probably not just comparing prices. You're wondering who won't cut corners on load ratings, who understands SCDF fire separation requirements, and who'll still pick up the phone two years after handover when you need to add another mezzanine level.

What We Do (and Don't Do) for Warehouse Projects

We handle structural and heavy-duty works for commercial and industrial spaces: racking systems, mezzanine floors, structural reinforcements, metal fabrication, and piling where needed. Most of our warehouse clients come to us because they need something load-rated and certifiable — not cosmetic fitting-out.

Here's what falls under our scope:

• Mezzanine floor construction — steel or concrete, engineered for specified live loads (typically 5kN/m² for storage, 7.5kN/m² if you're parking forklifts up there)
• Heavy-duty racking and shelving systems — custom-fabricated, anchored properly, with PE-stamped load calculations if required by your landlord or insurer
• Structural modifications — removing or adding columns, reinforcing slabs, extending roof spans
• Metal fabrication — steel staircases, platforms, roller shutter frames, support beams
• Piling and foundation works — when you're building on soft ground or need to support serious point loads

What we don't typically do: office partitions, false ceilings, air-con ducting, or floor epoxy. Those are finishing trades. If that's your main scope, you want a general renovation contractor — our sister company Larry Contractors handles that side of things for HDB-licensed spaces.

Why Most Warehouse Projects Go Wrong (and How We Avoid It)

The cheapest quote almost always misses something. We've been called in to fix enough botched jobs to know the pattern.

Load Calculations That Don't Add Up

A mezzanine floor isn't just a raised platform. It's a structure that needs to carry live loads, dead loads, and dynamic loads without deflecting beyond L/360 (that's the maximum acceptable sag). We've seen contractors build beautiful-looking mezzanines that bounce when a pallet jack rolls across them, or worse — crack the slab below because the columns weren't properly founded.

Every mezzanine we build comes with a structural engineer's certification. Not because the law always requires it (though many landlords and insurers do), but because we won't put our name on something that might fail in five years when you stack it full of inventory.

Fire Code Compliance That Gets Ignored

SCDF has very specific rules about fire separation, escape routes, and compartmentation in industrial buildings. Add a mezzanine and suddenly your single-storey warehouse might need a second fire escape. Extend your racking too close to a sprinkler head and you've created a dead zone that won't pass inspection.

We factor this in at quotation stage. It's slower than just saying "yes, can do" to everything, but it means the job doesn't get held up three weeks in when SCDF rejects your plans.

Contractors Who Vanish After Handover

Warehouses evolve. Six months after your build, you might need to add another row of racks, reinforce a section because you're storing heavier goods, or relocate a column because your new conveyor system needs the space.

The contractor who gave you the lowest price? Often unreachable. We still get calls from clients whose projects we completed in 2015 and 2016 — not because something broke, but because they're expanding and they want the same team who knows their building's load limits and anchor points.

How We Actually Work on a Warehouse Project

Our process hasn't changed much since 2014, because it works.

Site Assessment and Load Survey

We visit the site — always. We need to see your existing slab thickness, check for underground utilities if we're drilling anchors, measure ceiling heights, and understand how you actually use the space. A ambient-temperature dry storage warehouse has very different needs from a cold room facility or a workshop with overhead cranes.

If you're renting, we also need to see your landlord's requirements. JTC, HDB, and private landlords all have different rules about what you can and can't modify.

Engineered Drawings and PE Endorsement

For any structural work, we engage a Professional Engineer (PE) to prepare calculations and endorse the drawings. This isn't optional for us. It's how we ensure the build is safe, and it's what your insurer will ask for if you ever make a claim related to structural failure.

If your project doesn't need PE endorsement (small racking systems, non-structural platforms), we'll tell you. But if it does and another contractor is quoting without it, that's your red flag.

Build, Inspect, Certify

We fabricate most metalwork in-house — it's faster and we control quality. Concrete mezzanines get poured on-site with our usual crew. Once complete, the PE inspects and issues a certificate of structural adequacy.

You get a full set of as-built drawings, load rating plates (if applicable), and all PE certificates. Keep them. You'll need them when you sell the business, renew your lease, or apply for a change of use.

What to Ask Before You Hire Any Warehouse Contractor

Here's what we'd ask if we were in your position:

• "Do you have a PE on your team or do you engage one per project?" — Either is fine, but "we don't need a PE" for structural work is a bad sign.
• "Can I see a similar project you've completed with load certs?" — Photos are nice. Documentation is better.
• "What's your defects liability period and how do I reach you after handover?" — If they hesitate, that's your answer.
• "How do you handle changes mid-project?" — Scope creep happens. You want a contractor who documents variations properly, not one who argues about what was "included" six months later.
• "Are you BCA-licensed and insured?" — For general builder works, we carry BCA General Builder Class 2. For trade-specific work, the relevant trade licence. Insurance should cover public liability and workmen's compensation at minimum.

Why We Stopped Taking Every Warehouse Job (and Started Being Selective)

Around 2018, we noticed a pattern. Our commercial clients — the ones whose warehouses and factories we'd built — started asking us to work on their homes. Landed properties, usually. Reconstruction, A&A, structural extensions.

We said yes carefully. Homes are different. The stakes are higher. The regulations are stricter. But the principles we learnt building 1,500+ commercial structures — accurate load calcs, proper PE involvement, doing it right the first time — transferred directly.

Today, our main focus is landed residential builds. We still take on commercial warehouse projects, but only for existing clients or referrals, and only when the scope suits our strengths: structural, heavy-duty, engineered works.

If you're looking for a warehouse contractor for racking, partitions, and basic fit-out, there are faster and cheaper options. If you're building a mezzanine that needs to hold 10 tonnes per bay, or you're cutting into a load-bearing wall to install a new roller shutter, or you need something PE-certified and built to last — we're still very much in that game.

Frequently Asked Questions

How much does it cost to build a mezzanine floor in a Singapore warehouse?

We don't quote without seeing the site, but as a rough guide: steel mezzanines typically start around $150–$250 per square metre for basic storage-grade structures, excluding staircases and railings. Concrete mezzanines cost more but handle heavier loads. The biggest variables are load rating, height, access requirements, and whether your existing slab can take the column loads without reinforcement. We always provide a fixed-price quote after the site survey and engineering assessment.

Do I need BCA approval to build a mezzanine in my rented warehouse?

It depends on the size and your landlord. For most mezzanines, you don't need BCA building plan approval, but you do need your landlord's written consent and often their requirement for PE-certified drawings. JTC and HDB have their own submission processes. SCDF may also need to review if the mezzanine affects fire escape routes or compartmentation. We handle these checks as part of our quotation process so there are no surprises mid-build.

Can you reinforce my warehouse floor to support heavier racking?

Yes, if the existing slab and subgrade allow it. We start with a structural assessment — sometimes a simple core test to check slab thickness and concrete grade. If your floor is under-strength, options include localised thickening, adding a reinforced topping slab, or installing isolated pad footings under the rack columns. The PE will calculate what's needed based on your actual load requirements, not guesswork.

How long does a typical warehouse mezzanine project take?

From quotation acceptance to handover, usually 6–10 weeks for a straightforward steel mezzanine. That includes engineering (2 weeks), fabrication (2–3 weeks), installation (1–2 weeks), and inspection. Concrete mezzanines take longer due to curing time. The timeline can stretch if there are landlord approval delays or if we discover site conditions that need remedial work first. We give you a detailed programme at contract stage.

Do you only do new builds or can you modify existing warehouse structures?

We do both. A lot of our work is actually modifications — adding a mezzanine to an existing warehouse, extending racking, removing columns to create clear spans, or reinforcing floors for new equipment. Modification work often needs more careful engineering than new builds because you're working around existing loads and constraints. As long as it's structural or heavy-duty metalwork, it's in our scope.
