- A tender programme and a construction programme should differ only by two things: the title and the contract start date.
- Stripping detail from a tender programme does not simplify it. It transfers undisclosed risk to the client and the builder.
- Lead times, sequencing, access constraints, commissioning windows and staging are all knowable at tender.
- Under AS 4000-1997, the programme submitted at tender becomes a contractual reference point.
- The cheapest place to find a scope gap is before contract signature. The most expensive place is after installation.
What is the difference between a tender programme and a construction programme?
In Australian commercial fitout and refurbishment work, a tender programme is the schedule a builder submits with their bid. A construction programme is the schedule the builder executes to once the contract is signed. In theory these are distinct documents. In practice, if they are built properly, they should be the same document with a different header.
The title changes. The contract start date slots in. Float may get redistributed. That is it. Every lead time, every sequencing constraint, every dependency that existed at tender still exists on day one of construction. The site has not changed. The drawings have not changed. The scope has not changed.
Yet tender programmes routinely arrive with half the detail stripped out. Clients review them, award the work, and then watch the real programme appear four weeks later showing blown out dates, new dependencies, and a story about why tender stage estimates were always going to be preliminary.
They were not preliminary. They were incomplete.
Why builders under detail tender programmes
Three reasons, in descending order of honesty.
The first is competitive pressure. If a competitor is showing a 36 week programme on the same job, showing 42 weeks with your workings visible feels like handing the client a reason to pick someone else. The industry rewards the shorter bar at tender and punishes nobody for the slip that arrives later.
The second is capability. Tender teams often do not include the people who would actually build the job. The estimator builds the programme, the PM inherits it, and the gap between what was shown and what is real gets discovered in preconstruction. This is particularly common on commercial fitouts under $1m, where tender budgets are thin and detailed programming gets treated as post award work.
The third is cultural. Detailed tender programmes look slow. They show 14 week lead times on European laminated glass, 6 week structural engineering sign off cycles, 3 week commissioning and witness point windows. A client looking at two bars on a page next to a competitor single bar reads it as inefficiency rather than realism.
All three reasons are explicable. None are defensible on a project that goes sideways.
What should a tender programme include in Australian commercial construction?
For a commercial fitout or refurbishment in Victoria, South Australia or New South Wales, a tender programme should show, at minimum:
- Long lead procurement items, with supplier lead times on the bar. For fitout work, this typically means joinery, specialist glazing, custom metalwork, imported finishes, and any long lead mechanical or electrical equipment.
- Sequencing dependencies for services rough in, ceiling works, acoustic treatments, fire systems, and final finishes. Where a ceiling mounted element needs to be fixed to the slab soffit before services install, that sequence belongs on the programme at tender, not as a pre construction discovery.
- Access and staging constraints specific to the site. Occupied tenancies, after hours restrictions, goods lift bookings, loading dock access, noise windows in hospital and hotel environments. Every one of these is on the drawings and in the project brief. A builder who reads the full tender pack will see them.
- Live services and isolation windows for refurbishments of operational facilities. Hospital sub acute units, operating hotels, live retail trading, open educational campuses. The client operational reality drives the programme and must be reflected at tender.
- Statutory and contractual hold points. Council inspections, landlord approvals, building surveyor mandatory inspections under the Building Act 1993 (VIC), commissioning witness points, fire certification, certificate of occupancy pathways.
- Float distribution, showing where buffer sits and where it does not.
Master Builders Victoria guidance on commercial tendering and the standard AS 4000-1997 programme provisions both treat the submitted programme as a document with contractual weight. Detail at tender is not optional; it is the document both parties will reference when things move.
The real cost of a thin tender programme
On a $250k commercial fitout, a four week programme blowout typically lands somewhere between 8% and 15% of contract value once prelims, escalation, and disruption are counted. That is $20k to $37k of margin evaporation that was not on anyone risk register at tender.
Scale it up. On a $2m refurbishment, the same four week delay driven by unrecognised lead times or missed sequencing sits closer to $120k to $180k. The money does not disappear. It moves. Sometimes to the builder balance sheet as eroded margin, sometimes to the client as a variation, sometimes to the subcontractors whose programmes were built on the original bars. Often to all three.
None of this is surprising. All of it is avoidable.
What clients should demand from tenderers
For client side project managers and consultants reviewing tender submissions, three quick tests separate a real programme from a placeholder.
First, can you see the supplier lead times? If every procurement activity is the same 2 week bar, the builder has not costed their supply chain. Long lead items should look long.
Second, is there a legible critical path? If the programme is a collection of parallel bars with no dependency lines or clear hand offs, no one has thought about sequencing.
Third, are the site specific constraints visible? On an occupied refurbishment, you should see after hours windows, staging zones, decant sequences, and live services isolations on the bar. If the programme could apply to any empty warehouse, it probably was copied from one.
A tender programme that fails these three tests should be queried before award, not after.
Build the programme like you are building the job
Because you are. Every line on the programme is a decision the site team will execute. If the lead time is not on the bar, someone will forget to order. If the sequence is not shown, someone will install it in the wrong order and pull it apart. If the commissioning window is not protected, handover will slip.
Include a summary view with key milestones for the executive audience. But the detailed programme, with every lead time, every dependency, every sequencing constraint, has to exist before the contract is signed. Not after.
If the programme is not clear at tender, the risk is not either. And that risk gets carried by someone. If the builder has done the work properly, it will not be them.
What is the difference between a tender programme and a construction programme in Australia?
A tender programme is submitted with a builder's tender bid. A construction programme is the schedule used once the contract is awarded. Built properly, they should differ only in title and contract start date.
Who is responsible for programme detail at the tender stage?
The tendering builder. Under AS 4000-1997 and most amended commercial contracts, the programme submitted with the bid becomes a contractual reference document.
What should a tender programme include for a commercial fitout?
Supplier lead times for long lead items, sequencing dependencies between trades, site specific access and staging constraints, live services isolation windows, statutory hold points, and float distribution.
Can a tender programme change after award?
Yes, through contractual mechanisms such as Extensions of Time and programme updates. But the starting position should be a programme that reflects real delivery.
Is it acceptable to submit a high level tender programme and develop the detail post award?
On fixed scope commercial fitouts, a detailed tender programme is industry standard. Submitting a high level version invites reprogramming disputes that both parties lose.
