Tender Estimate Bays
We measure the issued documents and produce a priced tender for submission, with assumptions visible on the sheet and a single reviewer sign-off before the bid goes out.

The Desk and What It Does
An estimating practice for computer integrated systems
Emerald Business Solutions Group Limited works in the commercial estimating line for computer systems design and related services. The practice is not a general contractor and it does not install cable or furniture. What it does is take the drawings, specifications and schedules that arrive from a design team, measure them against a real market, and return a tender estimate that a client can sign without a second guess. That narrowness is deliberate. Estimating a system integration package is different from estimating a building package, and the difference sits in the interfaces: the data cabinet needs a room, the room needs power and cooling, the cooling needs a riser, and every one of those boundaries becomes a line on the sheet that someone must own.
Our desk sits at Rm 402 4/F Lippo Centre Tower 2, 89 Queensway, Admiralty, Hong Kong - 999077, Hong Kong (HK). From that room the practice runs six repeating services: tender estimate bays for bid submission, cost sheet runs for live projects, variation order desks for change control, subcontractor quote rounds for the supply chain, escalation claim reviews for the arguments that follow, and final account sittings for the close-out. Each one is a desk with a routine, a set of forms and a named reviewer, and we keep them separate on purpose so that a live project never loses its estimate to a bid that is due on Friday.
The practice keeps a small team and a long memory. Drawings change, suppliers rotate and prices move, but the arithmetic of a fair estimate does not. We measure quantities from the issued documents, price them against three independent supplier positions wherever the market allows, and set out the assumptions in plain sentences on the face of the sheet. When a client asks why a line costs what it costs, the answer is already written down beside the number. That habit is the reason most of our work arrives by referral from engineers, project managers and quantity surveyors who have sat in a final account meeting and watched a badly kept cost sheet fall apart.
Six Services, One Beam
The services rest on the beam in the order the project needs them
Each tray below is a standing service of the practice. They are not packages to buy in sequence so much as desks that a project visits as it moves from bid to close-out. A fuller description of each one sits on the services page.
Cost Sheet Runs
A live project cost sheet is rebuilt on a fixed cycle against actual commitments, so the forecast never drifts more than one round behind the site.
Read the run →Variation Order Desks
Every change is measured, priced and dated at the desk before the instruction is acted on, so the variation is agreed while the memory of it is still fresh.
Read the desk →Subcontractor Quote Rounds
We run structured quote rounds across the supply chain, compare the returns on equal terms and record why the chosen position was chosen.
Read the round →Escalation Claim Reviews
When material or labour prices move against the contract, we build the evidence file, test the entitlement and put the claim in front of the other side.
Read the review →Final Account Sittings
The close-out is prepared as a sitting: measured, reconciled and presented, so the final account closes with a signed number rather than an argument.
Read the sitting →Why the Estimate Is the First Drawing
Before a single cabinet is bolted down, the estimate is the only document that describes the whole job in one place. We treat it with the same care as a drawing.
A computer integrated systems project is assembled from parts that each belong to a different trade. Structured cabling belongs to one supplier, the comms room fit-out to another, the power and cooling to a third, and the software integration to a fourth. When those parts meet at a boundary, the question of who carries the cost of the boundary is exactly the question an estimate has to answer before the contract is signed. Our tender estimate bays exist for that single purpose. We sit with the drawing set, trace each boundary from the schedule, and make the division of responsibility explicit in the priced document rather than leaving it to a site argument six months later.
The cost sheet runs then carry the same arithmetic through delivery. A cost sheet that is only updated when someone remembers to update it is not a cost sheet; it is a rumour. We rebuild the sheet on a fixed cycle, compare the forecast against orders and invoices, and mark every line that has moved since the last round. The result is a document a project manager can open on a Monday and trust on a Wednesday.
Where Variation Orders Earn Their Keep
A variation order is not paperwork that follows a change; it is the change. The variation order desks at this firm price each instruction at the moment it is given, using the same rate basis as the original tender. A client who asks for a late change gets a number that can be compared to the original line, and a contractor who proposes an alternative gets a clear answer about the cost consequence. That discipline keeps the final account short. Escalation claim reviews sit alongside it, for the cases where a contract allows a price to move because the market moved, and we build the evidence file as if it will be read in a hearing, because sometimes it is.
The subcontractor quote rounds are the quiet engine behind all of this. We ask the supply chain for structured returns, compare them on a like-for-like basis, and write down why one position was chosen over another. That record matters twice: once at award, and again at the final account sitting when someone asks whether the market was tested. The final account itself is a sitting rather than a scramble, prepared in advance, reconciled line by line, and presented with the supporting record already bound. If you want to see the whole routine in one place, the services page sets out each of the six desks in detail.
How a Tender Estimate Is Built
Each bay follows the same four movements, so a client always knows what stage a bid has reached.
- Take-off: quantities measured from the issued drawing set and cross-checked against the schedule.
- Pricing: three supplier positions per line, with the chosen basis recorded on the sheet.
- Risk: allowances set out separately so the client can see what is held back and why.
- Sign-off: one named reviewer reads the whole sheet before the bid leaves the desk.
What We Need From a Client
A good estimate starts with clear documents. These four items save a full round of questions.
- An issued drawing set with a revision mark and a date.
- A specification or schedule of works that names the standards to be met.
- A programme with the dates that matter, especially any phased handover.
- A named contact who can answer a question about the design while the bid is open.
Emerald Business Solutions Group Limited opens its final account window each quarter from the Lippo Centre desk, and a project that reaches that window with its records intact closes in a single sitting.
Records, Dates and the Long Tail of a Project
Most final accounts fail for one reason: the record was not made when the event happened. Our desks are built to make the record while it is still easy.
A commercial project has a long tail. The tender is issued, the contract is awarded, the site runs, the changes accumulate and then, two years after the last cabinet is powered down, someone sits down to close the account. The firms that close well are the ones that treated every intermediate event as something worth writing down. That is why the variation order desk dates each instruction and files the priced response beside it, and why the subcontractor quote rounds keep the full comparison record rather than only the winning price. The record is dull while it is being made and priceless when it is needed.
The practice also keeps the distinction between an allowance and a commitment in plain view. An allowance is a number we set aside because the design is not finished; a commitment is a number we have actually placed with a supplier. Mixing the two is how forecasts become fiction. On every cost sheet run, the two are shown in separate columns, and the reviewer asks a simple question of each line: is this money spent, money promised, or money held back. If the answer is not obvious from the sheet, the sheet is wrong and it goes back for another run.
A Small Team by Choice
Emerald Business Solutions Group Limited is a small estimating practice, and that is a design decision rather than a limitation. A desk with three or four reviewers can keep a project in its memory from tender to final account, which is exactly what a long integration programme needs. When a client calls with a question about a line that was priced eighteen months ago, the person who answers can usually find the working paper in a folder rather than in an archive request. That continuity is what we sell alongside the arithmetic.
Clients reach us by email at estimates@builimited.autos or by phone on +17018001092. If you are preparing to submit a bid and want a second reading of the estimate, or if you are closing an account and want the record assembled properly, the contact page has the full desk details and a short form that reaches the reviewers directly.
