Get one unit right,then repeat it perfectly.

For a developer, or anyone fitting out many identical units, the money is made or lost in the repetition. ELS by ALUMAX builds the specification once and then makes it repeatable: prototype a unit, freeze the spec, build a mock-up, price it to a BOQ, standardize it across every unit, and QC each one to the same hold-points. One approved unit, repeated with discipline — instead of the same avoidable mistakes quietly multiplied across fifty. Fix a flaw in the prototype and you have removed it from the whole development.

Quick decision rules

How to decide before you scale

A multi-unit rollout fails when it scales before it is settled — every unsolved flaw is multiplied. Settle these before you repeat.

Get one unit right

The prototype does the thinking once.

At scale, thinking is the cheapest thing you can buy and the most expensive thing to skip. The prototype is where every decision is made, tested and settled — once.

Prototype the unitThe first unit is where every problem surfaces — layout, services, buildability, cost. Solve them here, not in unit forty.ELS checks: One unit designed, specified and pressure-tested before anything repeats.
Freeze the specificationA specification that keeps changing after rollout starts turns fifty units into fifty slightly different jobs.ELS checks: Materials, details and hardware locked to one schedule before scaling.
Build a mock-upA drawing hides what a physical unit reveals — the fit, the finish, the things that only show when built.ELS checks: A mock-up built and reviewed so the standard is seen and agreed, not imagined.
Price to a BOQCommitting budget to an estimate is a gamble; a real unit gives quantities you can actually price.ELS checks: A BOQ-ready specification — quantities and schedules the rollout can be priced against.
Then repeat it perfectly

Discipline is what makes repetition pay.

Once the unit is right and the spec is frozen, the value is in repeating it exactly. Standardization and unit-by-unit QC are what stop the rollout from drifting.

What's included

What the multi-unit specification covers

ELS designs the prototype, freezes the specification, standardizes the rollout and sets the QC. ALUMAX supplies and installs the cabinetry and systems, priced per BOQ. Main construction and compliance sit with the developer's contractor and consultants.

Included in the specification
  • Prototype-unit design and specification
  • A frozen material, detail and hardware schedule
  • A mock-up build brief and review
  • A BOQ-ready specification — quantities and schedules for pricing
  • A standardization pack across units, with defined variants
  • A per-unit QC hold-point checklist
  • Coordination of the repeat rollout to the frozen spec
Not included (coordinated separately)
  • Main construction and base-building — the developer's main contractor
  • Authority submissions and compliance — consultants, licensed
  • Product supply pricing — ALUMAX, per the BOQ
  • Trade execution across units — licensed trades
  • Final contract price — confirmed per BOQ and tender
  • Site-wide project management beyond the specification scope
What drives the price

What drives a multi-unit quote

The prototype specification starts from RM1,500 (excl. SST); the standardization and rollout run on a project basis. What follows depends on these.

Number of unit typesEach distinct unit type needs its own prototype and frozen specification.
Depth of the mock-upA partial mock-up of the key rooms versus a full show-unit build.
BOQ detail levelHow granular the quantities and schedules need to be for the tender.
Number of units and variantsThe total rollout and how many controlled variants — corner, end, mirror — it carries.
ALUMAX package levelEssential, Signature or Bespoke across the units — product pricing confirmed by ALUMAX per BOQ.
Site condition & accessSibu site measurement from RM300, outstation from RM500 — creditable on confirmation.

Indicative only — the final quotation follows site measurement, material selection and approved scope. Prices exclude SST.

How to prepare

How to prepare for the Pre-Check

A few things that make the prototype faster and the rollout more accurate.

  • How many units, and how many unit types
  • The target buyer and tier for each unit type
  • Your timeline and rollout order
  • Who your main contractor is
  • Your budget per unit
  • Any authority or compliance constraints
  • Whether you need a show unit or sales gallery

Common questions

Why prototype one unit before building all of them?

Because at scale, every problem you do not solve in the first unit gets multiplied by every unit after it. The prototype is where the layout, the services, the buildability and the real cost are worked out and pressure-tested — so the flaws surface once, in unit one, instead of quietly repeating through unit forty and turning up as forty snag lists. A perfected prototype de-risks the whole rollout: you know exactly what each unit contains, what it costs, and how it is built, before you commit the budget. It is the single highest-leverage step in any multi-unit job, and it is the one most rollouts skip.

What does "freeze the specification" mean, and why does it matter?

Freezing the specification means locking the materials, details and hardware to one agreed schedule before the rollout scales, and then not changing them mid-stream. It matters because a specification that keeps moving after units are already being built turns a repeatable job into fifty slightly different ones — every change ripples through pricing, procurement and every unit not yet done, and the cost and variation both climb. Freeze late and you are re-pricing and re-working constantly; freeze first, and every unit is built against the same known, costed standard. The discipline of the freeze is what makes the economics of repetition actually work.

Do you build a physical mock-up?

Yes, because a drawing hides what a built unit reveals. A mock-up — a full show unit, or at least the key rooms built to the frozen spec — lets everyone see and test the actual fit, finish and buildability before it is repeated across the development. It also gives a real basis for the BOQ: quantities and schedules taken from a unit that exists price far more accurately than an estimate off a plan. The mock-up is where the standard is agreed by seeing it, not imagining it, and it doubles as the sales show unit. Committing a multi-unit budget without one is committing to a guess.

How do you keep quality consistent across many units?

By standardizing to one schedule and then QC-ing every single unit against the same hold-points. Standardization means each unit is built from the identical material, detail and hardware schedule, so it is genuinely the same rather than merely similar — no drifting toward whatever the crew had on hand that week. The per-unit QC checklist then verifies each unit at the same defined hold-points before it is signed off, rather than spot-checking a few and assuming the rest are fine. Together they are what stop a development where the first units are excellent and the last ones are quietly worse. Consistency at scale is a system, not a hope.

Can you handle unit variations — corner, end, mirrored?

Yes — the key is to define the standard and its permitted variants up front, so variation is controlled rather than improvised on site. In any real development some units differ: a corner unit, an end unit, a mirrored layout, a slightly larger type. Left undefined, those differences multiply as each crew solves them its own way, and the QC and pricing fall apart. So the standardization pack sets the base unit and then documents each allowed variant explicitly — what changes, what stays, and how. Every unit on site then maps to a defined type, the BOQ stays accurate, and the QC checklist still applies. Controlled variation, not improvised.

How much does a multi-unit specification cost?

The prototype-unit Design + Specification starts from RM1,500 (excl. SST) per unit type, and the standardization, BOQ and rollout coordination run on a project basis scoped to the number of units and variants. Site measurement is from RM300 in Sibu and RM500 outstation, creditable on confirmation. The value is in the leverage: the fee to perfect one prototype is small against the cost of repeating an unsolved flaw across a whole development. The final contract price is confirmed per the BOQ and tender. Prices exclude SST.

How ELS coordinates it

The weeks ELS saves — by ordering, not waiting.

Freeze the drawings, order every long-lead item the same day, and the 8-week factory lead runs concurrent with demolition and wet works instead of after them.

Developer / multi-unit · ~16 weeks +10 QC hold-pointsBatched & phased

The binding constraint here: Batched procurement against a frozen prototype — every unit is ordered together at W0, then built and handed over block by block.

  • Prototype one unit and freeze the spec; a mock-up and BOQ price the rollout before scaling.
  • One shared procurement batch — all units / blocks ordered together at W0.
  • Certified materials and a physical sample approved before any order (procurement-led jobs).
