BUILDERS / TENDERS & PRICING
When a tender asks for slip testing or an AS 4586 slip rating, the price depends on what is actually being assessed. Premrest helps Brisbane builders, estimators and project managers separate on-site testing of existing floors from classification of new materials, then quote a defined scope.
Send drawings or a scope ↗TWO DIFFERENT QUESTIONS
A specification can ask for a product’s slip rating, an on-site test of floors already in the building, or a pendulum test after the new floor is down. Those are not the same allowance. Read the clause, then send the drawings so the quote follows the work rather than a generic “slip testing” line.
AS 4663:2013 addresses measurement of existing pedestrian surfaces. If the building already has tile, stone, vinyl or coated concrete in place — or the tender wants the laid floor tested later — that is an on-site pendulum brief, not a product datasheet.
Understand the testing ↗AS 4586:2013 addresses classification of new pedestrian surface materials. An AS 4586 slip rating on a supplier sheet describes the unused product. It is not a current measurement of the same floor after it has been laid, grouted, sealed and walked on.
Send the specification clause ↗A usable figure needs the number of areas, wet or dry conditions, access and after-hours constraints, and a written report. Without those, a lump sum is a guess that tends to move once the site is real.

Premrest prices against a defined scope. The tighter the pack, the less the estimator has to carry as risk.
Send the tender pack ↗Send the slip-resistance specification, finishes schedule and a marked plan. Note which areas are existing, which are new, and whether the test is wanted before, during or after the floor is laid.
Agree how many locations, whether wet or dry conditions are required, site induction, escorts and any after-hours window. Occupied Brisbane buildings often only release floors before trade or after close.
Quotes are prepared promptly once the drawings or written scope are in. The price is for the brief you sent, not a standing rate for every job.
Estimators often see “AS 4586” and “slip test” in the same paragraph. The first is about classifying new pedestrian surface materials. The second, when it means a visit to a Brisbane site, is usually measurement of a floor that is already there or will be there after install. Treating them as one line item is how an allowance ends up too thin for the visit, or priced for work that a supplier report has already covered.
Start with the words on the page. If the documents ask for a P classification of a nominated tile, that is typically a product classification under AS 4586:2013 — often sitting with the manufacturer or a laboratory report on unused samples. If they ask for on-site slip resistance testing of existing entries, amenities, wet areas or a floor the builder is about to take over, that is the AS 4663:2013 situation. If they want a pendulum test of the new floor before practical completion, that is a later visit and a different program date; see before-handover slip testing.
Premrest’s site work is wet pendulum testing of selected pedestrian surfaces under recorded conditions. Once a material is on the slab, grouted, coated or worn by following trades, it is an existing surface. A supplier’s AS 4586 slip rating does not travel automatically onto that floor. Say so in the tender response if the client has asked for both a product rating and a site test — they are two deliverables, and only one of them is a site visit.
If the job is a refurbishment of an operating commercial property, the existing floor may need testing before strip-out as well as after the new finish is down. List those as separate visits. The commercial wet-area slip testing page covers how occupied entries, kitchens and outdoor circulation are scoped when the building stays open.
A slip testing tender allowance is only as good as the variables you lock down. Include:
Leave a note where the drawings are silent. A quote that says “three amenities, one entry, wet pendulum, after hours, report” is usable. A quote that says “slip testing as specified” is not, because the specification may be mixing a product rating with a site test.
Quotes are prepared promptly on receipt of drawings or a written scope. Send the specification clause, a marked plan or finishes schedule, the number of areas you can see, and the access story. There is no published service-level promise on this page; the time to a figure depends on how complete the pack is and whether the clause needs a conversation before it can be priced.
Call 1300 207 915 if you are mid-tender and need help reading whether the clause is asking for a product classification, an on-site test, or both.
Once the floor is down and someone asks for a test before handover, occupancy or practical completion, the brief changes. You are no longer pricing a maybe; you are booking a visit to a specific surface. That path is set out on the before-handover slip testing page. Methods and reporting are explained on the slip resistance testing page. The Brisbane wet-area checklist helps you describe conditions on an exposed or still-active site.
The contact page is the quickest way to send drawings. Use the message field for the clause wording, the area count and any after-hours constraint.

COMMON QUESTIONS
Call 1300 207 915 if the specification mixes a product rating with a site visit.
AS 4663:2013 addresses measurement of existing pedestrian surfaces, including floors already installed on a site. AS 4586:2013 addresses classification of new pedestrian surface materials. A supplier’s AS 4586 slip rating describes the unused product; it is not the same as an on-site measurement of the floor after it has been laid.
Not necessarily. An AS 4586 slip rating is a classification of new material, often taken from a supplier or laboratory report on unused product. On-site pendulum testing of an installed floor is a different brief and is treated as measurement of an existing surface. Send the specification clause so the two can be separated in the quote.
Allow for the number of areas or surface types, whether wet or dry conditions are required, access and any after-hours or induction constraints, and a written report. If drawings or the specification are incomplete, say what is still unknown so the quote can flag it rather than hide it in a lump sum.
Quotes are prepared promptly once Premrest has the drawings or a written scope, the specification clause if there is one, and enough detail on areas, access and timing. There is no fixed turnaround published here; send the pack and we will come back with a defined price against that brief.
No. A report records the areas assessed, method, conditions and results. It does not certify that a floor is safe or compliant, and it is not a guarantee of the finished work. Confirm the requirements that apply to the project with the relevant adviser.
