Why IT has to be in the room before the design freezes
The single most common reason an office fit-out or move slips its timeline, or blows its budget, is IT being brought in after the interior design is already decided. Desk layouts, meeting room positions and ceiling plans get finalised without a single question asked about data point counts, outlet density, cabling routes or where the comms room actually goes, and by the time anyone thinks to ask, changing the drawing means a costly variation order rather than a line that was there from the start. Hong Kong's PTS Managed Services, whose office relocation methodology is one of the more thorough public examples of this discipline, put it plainly: bringing IT in late is the single most common reason a move slips, and the fix is to get IT into the fit-out design before it freezes, not after.
The mechanism that makes this work in practice is a proper tech brief, a document that translates IT's requirements into something an interior designer or architect can actually draw: outlet counts and positions per desk, data point counts per room, comms room dimensions and power load, cabling containment routes, and AV joinery requirements. Building that brief properly is a topic detailed enough to deserve its own guide, coming separately. What this one covers is the budget and the checklist that brief needs to be built from.
Businesses that get this right are generally following some version of a structured methodology rather than improvising room by room. PTS's own relocation framework, one of the more thorough public examples, runs six phases: survey and inventory of the current environment, move planning with a defined cutover and rollback sequence, controlled decommissioning of the old site, secure transport, rebuild and reconfiguration at the new site, then testing before go-live. A pure fit-out without a physical move can skip the transport and decommissioning steps, but the discipline of planning the cutover sequence before touching anything is the same, and it is the single biggest difference between a fit-out that goes live smoothly and one that spends its first fortnight firefighting.
Build the budget by category before you build the checklist
The approach that consistently works, and the one worth insisting on before a single vendor conversation happens, is to build the budget category by category first, so every decision that follows has a ceiling to work within rather than being negotiated line by line against a designer's finished plan. Base fit-out cost in Singapore runs roughly S$50 to S$70 per square foot for a basic specification, S$80 to S$120 for mid-range, and S$130 to S$180 or more for a premium build, and IT is rarely included in that headline number by default. As a planning benchmark, add S$15 to S$30 per square foot specifically for IT infrastructure on top of whichever tier applies, covering structured cabling, network switches, server room cooling, Wi-Fi access points and AV equipment. That IT allowance is consistently one of the most frequently missed line items in a fit-out budget, often only surfacing weeks after the design contract has already been signed, at which point it competes with a fixed budget rather than shaping it.
| Category | Typical share of the IT/AV budget | What it covers |
|---|---|---|
| Network infrastructure | 25–35% | Switches, structured cabling, Wi-Fi access points |
| Meeting room AV | 30–40% | Displays, cameras, audio, Teams Rooms or equivalent compute |
| End-user devices | 15–20% | Laptops, monitors, docking stations, peripherals |
| Security systems | 10–15% | Access control, CCTV, alarm integration |
| Room scheduling & collaboration software | 5–10% | Booking panels, licensing, ongoing SaaS cost |
The checklist: what to sort before the contractors arrive
Connectivity, because it has the longest lead time
Order internet circuits the moment the lease is signed, before the fit-out design is even fixed. Circuits are consistently the longest lead-time item in the entire project, and a delayed connection has derailed more go-live dates than any cabling or AV issue. In Singapore specifically, a fibre circuit typically takes 16 to 34 working days to provision from a successful application, and a first-time applicant with a given ISP should expect to furnish a deposit and an ACRA Bizfile before the application is even accepted, neither of which is quick to arrange the week before go-live.
On the circuit itself, a 100% uptime SLA is rarely necessary for a typical Singapore office and is usually a premium worth questioning rather than defaulting to. Contention ratios are not advertised by any provider, so the more reliable way to buy genuine redundancy is to take two circuits from different providers and confirm they run on physically different fibre backbones, not just different brand names on the invoice. Some providers resell capacity over shared infrastructure such as Nucleus Connect, while SingTel, and StarHub on some routes, run their own fibre; two circuits that both ultimately depend on the same physical path provide far less protection than they appear to on paper. This is worth confirming with each provider before signing, not after a shared fibre cut takes both lines down at once.
Cabling and containment: the decision that gets built into the walls
Cat6A is the right specification for the overwhelming majority of offices, supporting 10Gbps at full 100-metre runs and handling PoE++ for current Wi-Fi 6/6E access points at only a modest cost premium over Cat6. A typical 50-point cabling job for an SME office in Singapore runs roughly S$6,500 to S$10,000; Cat8, a data centre specification with a 30-metre range and no standard desktop equipment to use its capacity, is rarely justified for a general office and worth questioning if a vendor proposes it. What matters most for this checklist is timing rather than specification: containment routes and sizing need to be locked in before the design freezes, not fitted around a finished ceiling plan, because that single decision is the hardest and most expensive one to reverse once contractors are on site. The finer detail, cable categories, fibre backbone, patch panel labelling, and what to demand in a contractor's test certification, is covered properly in a dedicated structured cabling guide.
The server or comms room: placement, power and cooling
The comms room is one of the few spaces in an office fit-out where the interior designer's default instinct, tuck it into whatever awkward space is left over, is actively the wrong answer. It needs to be specified as a first-class room in the design: enough space for the rack, patch panels and switches, dedicated power circuits sized for the equipment load, and genuine ventilation or cooling, because network equipment generates real heat and a rack in a poorly ventilated space will fail. This is a placement and power decision that has to be made at the same time as the rest of the floor plan, not retrofitted once the walls are up.
Wi-Fi, power and desk layout: where IT and the interior designer have to talk directly
Wi-Fi coverage should be survey-led and heat-mapped against the actual, final desk and room layout before anyone moves in, not assumed from a generic access point count; a heat map done against last year's floor plan is close to useless once the designer has moved a meeting room or added a partition wall. It is also worth asking who produced the heat map: one done with a single vendor's own manufacturer tools is not an independent result, and a more reliable check is an independent survey tool such as Ekahau, run through one of its certified partners, with a planning heat map before installation and a validation heat map after it, so coverage is confirmed rather than assumed. Full access point planning and site survey methodology is its own topic, covered in the dedicated Wireless Design for a New Office guide. Power planning has the same dependency in reverse: outlet density, generally four to six power outlets per workstation and two to four data points near a meeting room table plus additional points for AV equipment, only makes sense once the desk layout is fixed, which means electrical and data planning cannot be finalised until IT and the interior designer are working from the same drawing. This is precisely the coordination point a proper tech brief exists to solve, and precisely where it breaks down when IT is consulted after the desk plan is already final.
Security, access control and AV
Access control and CCTV cabling need to go in during first fix, alongside power and data, not as a bolt-on once walls are finished and painted. Meeting room AV, video conferencing hardware and Teams Rooms or equivalent should be installed and fully tested before the room is used for the first time, not discovered to be misconfigured in the middle of a client call. Both categories are easy to underestimate on a checklist and expensive to retrofit once cabling is buried behind a finished wall.
Building-specific constraints: consents, risers and goods lifts
Map every building consent required for riser access, comms room installation, ceiling access, power modifications and after-hours contractor work at the very start of the project, not once contractors are already booked. The most commonly missed constraint is goods lift and riser access: slots fill up quickly around month-end and quarter-end, and a business that leaves this until the fit-out is underway can find its own contractors unable to get equipment into the building on schedule, regardless of how well everything else has been planned.
The old office: decommissioning is a checklist item too
If this fit-out is part of a move rather than a renovation in place, the outgoing office is not simply switched off on the last day. Rack equipment needs to be securely wiped or destroyed before disposal, not left for a landlord's contractor to find, and most leases carry a reinstatement or dilapidation clause requiring cabling and fixed equipment to be removed to a specified condition, which is a cost that belongs in the same budget conversation as the new fit-out, not a surprise raised at lease-end inspection. Planning the old site's controlled shutdown alongside the new site's go-live, rather than treating it as an afterthought once everyone has already moved, avoids the scramble that otherwise happens in the final week.
The discovery questions worth answering before you brief anyone
A tech brief is only as good as the information that goes into it, and most of that information does not exist yet in a business's head until someone asks the right questions in the right order. A proper discovery pass, done before any vendor or designer conversation, covers roughly the same ground every time:
- Internet and telephony. Required bandwidth, whether a backup line is needed, how many staff take calls frequently, how many meeting rooms need a phone or conferencing endpoint, and whether calls to other branch offices or countries are frequent enough to shape the telephony choice.
- Network and Wi-Fi. Managed versus unmanaged switching, PoE requirements for access points and phones, whether a separate guest Wi-Fi network is needed, and site-to-site VPN requirements if there is more than one office.
- Security. Door access method (card, biometric or keypad), number of doors requiring a reader, number of CCTV cameras and how many days of footage need to be retained.
- Cabling load. Not just desks: non-wireless printers or copiers, card terminals, and any other fixed device that needs a data point, counted before the cabling quote rather than discovered afterwards.
- Where workloads actually run. On-premise, hosted, or cloud, for email, file storage and any line-of-business application, which determines whether a server room is even required at all; see On-Premise to Cloud for how to make that call properly.
- Backup and continuity. Retention period, and whether a copy needs to leave the building or the country, which is as much a question for the business as it is for IT.
A written discovery questionnaire with a simple response code, not applicable, to be confirmed, an estimated number, yes or no, gets this answered faster and more completely than an open-ended conversation, and it doubles as the record a vendor needs to quote against without another round of meetings. Equipment delivery lead time generally runs four to six weeks from order confirmation once the specification is settled, which is one more reason to have these answers ready early rather than mid-project.
The tech brief has to speak the interior designer's language
Every item above assumes the interior designer actually has the information in front of them at the point the design is being drawn, not delivered as feedback on a finished plan. A workable tech brief specifies outlet counts and exact positions per desk, data point counts per room, comms room dimensions, power load and cooling requirements, containment routes, and AV joinery needs, in the same drawing language the designer is already using, not as a separate IT document that has to be manually reconciled against the floor plan. Power and data planning has to happen before walls are built, floors are sealed and ceilings are closed; retrofitting a single cable run after construction is a modest cost, retrofitting an entire floor is not. Getting IT a genuine seat at the table from day one, and what specifically goes wrong when it arrives after the floor plan is already signed off, is worth a dedicated guide of its own, coming next.
Before the first contractor is booked
- Build the category budget first. Use the table above as a starting split, add the Singapore S$15 to S$30 psf IT allowance to the base fit-out cost, and add a 10 to 15% contingency before a single vendor quote is requested.
- Order circuits on day one. This is the longest lead-time item in the entire project and should never wait for the design to be finished.
- Get the tech brief into the designer's hands before the layout is fixed. Outlet counts, data points, comms room specs and containment routes need to shape the drawing, not react to it.
- Treat the comms room as a first-class space. Power, cooling and physical space for the rack are design decisions, not leftover space.
- Confirm building consents and lift bookings early. Riser access and goods lift slots fill up around month-end and quarter-end and can stall an otherwise well-run project.

Frequently Asked Questions
When should IT get involved in an office fit-out?
As soon as the lease is signed and before the interior design is fixed, not after. Bringing IT in late is consistently the most common reason an office fit-out or move slips its timeline, because internet circuits have long lead times, and cabling routes, containment sizing, outlet positions and comms room specifications all need to be locked in before the design freezes and construction begins.
How much should a business budget for IT in an office fit-out?
As a planning benchmark for Singapore, budget an additional S$15 to S$30 per square foot for IT infrastructure on top of the base fit-out cost, covering structured cabling, network switches, server room cooling, Wi-Fi access points and AV equipment. Within that, conference room AV and network infrastructure are typically the two largest line items. IT infrastructure is one of the most frequently missed budget items in a fit-out, often only discovered weeks after the design contract has already been signed.
What is the single most common reason an office IT fit-out goes wrong?
IT not being in the room when the interior design is decided. Desk layouts, meeting room positions and ceiling plans get finalised without input on data point counts, power outlet density, cabling containment routes or comms room placement, and by the time IT is consulted, changing any of it means an expensive variation rather than a line on the original drawing.
Do we need Cat8 cabling for a new office, or is Cat6A enough?
Cat6A is the right standard for the overwhelming majority of offices. It supports 10Gbps at full 100-metre runs and handles PoE++ for modern Wi-Fi 6/6E access points, at a small cost premium over Cat6. Cat8 is built for data centre environments, has a maximum range of around 30 metres which fails most office cable runs, and there is no standard desktop equipment that uses its 25 to 40Gbps capacity. If a vendor recommends Cat8 for a general office, ask what specific equipment requires that bandwidth; an inability to answer is a sign of upselling.
How long does it take to get an internet circuit connected for a new office in Singapore?
A fibre circuit typically takes 16 to 34 working days to provision from a successful application, and a first-time applicant with a given provider should expect to furnish a deposit and an ACRA Bizfile before the application is accepted. Ordering the circuit early is not sufficient on its own: many providers will not complete the physical install until the comms room and its cable routing already exist to terminate into, so the room build needs to be sequenced ahead of the ISP's visit or an express-install fee is the likely result.
Do we need a 100% uptime SLA internet circuit for a Singapore office?
Usually not, and it is typically a premium worth questioning rather than defaulting to. Contention ratios are not advertised by providers, so genuine redundancy comes from taking two circuits from different providers and confirming they run on physically different fibre backbones, not merely different brand names on the invoice. Some providers resell capacity over shared infrastructure such as Nucleus Connect, while SingTel, and StarHub on some routes, operate their own fibre; two circuits sharing the same underlying physical path offer far less protection than they appear to. This is worth confirming directly with each provider before signing, not after a shared fibre fault takes both lines down together.
