Playground equipment bought for a public park, a school, a housing estate or a municipal leisure site is normally supplied under a formal tender, and the tender document decides most of what the buyer ends up with. The process runs in four stages: the authority writes a specification, the suppliers respond to it, the responses are scored against published criteria, and the winning contract sets out what is delivered and what has to be demonstrated before handover. A buyer who reads the specification closely before the tender is issued, rather than after the responses arrive, controls the outcome. The three parts of a tender that most often go wrong are the evaluation criteria, the documentation schedule and the site conditions information. Each of them can be corrected before the tender opens, and none of them can be corrected afterwards without reopening the process.
This guide explains how a public playground tender is usually structured, what a supplier has to be able to evidence, how commercial playground manufacturer selection is normally evaluated, and what a buyer should confirm before the tender documents are issued. It also covers the insurance and liability documents that a public contract requires, the way a site handover is verified, and the points at which a tender is most often challenged. For a buyer comparing responses, the playground equipment scope and the documentation behind it are usually where the differences between suppliers become clear.

A public playground tender normally has a fixed sequence, and the sequence is published in advance. It opens with a notice that states the contract value band, the site, the closing date and the contact point for queries. It is followed by the tender documents themselves, which are the invitation to tender and the specification. The invitation to tender sets the rules of the process: who may submit, what form the response takes, how it must be submitted and by when, and how questions are answered. The specification sets the technical content: what is required, to which standard, and what has to be demonstrated. Some authorities add a separate site information pack, which usually contains the drawings, the ground investigation report and the utility information, and which is a legal document because the supplier relies on it when pricing the foundations.
The response stage is where the specification becomes concrete. A supplier returns a technical response that answers the specification item by item, a commercial response with the price broken into the items the authority asked for, and the supporting evidence: test certificates, insurance documentation, references from comparable installations and, where the specification asks for it, a sample or a prototype of a specific component. Clarification questions are answered in a written notice issued to every bidder, because in a public process the same answer has to reach every supplier. The award is then made against the published criteria, and the successful supplier enters a contract that sets out the deliverables, the programme, the payment schedule, the retention and the mechanism for correcting defects.

The technical specification is the part of the tender that determines whether the equipment is fit for the site, and it has to settle six things. It has to state the applicable standard, which for outdoor play equipment in Europe is EN 1176 and its related parts, and in the United States is ASTM F1487, and it has to state which parts of that standard are mandatory rather than informative. It has to state the fall heights and the age ranges, because the height of the equipment determines the impact-absorbing surfacing that has to be specified alongside it. It has to state the materials for the parts that matter to the site.
The remaining three requirements are the surfacing, the acceptance criteria and the scope. The specification has to state the playground surfacing requirement with its tested impact attenuation value, and it has to state the acceptance criteria at handover, so that both parties know what completion means before anyone starts work. It also has to state whether the foundations and the surfacing are in the supplier's scope or excluded from it. That last point is where the specification most often fails, because a scope that is silent on foundations produces quotations that differ by the whole cost of the bases, and neither the authority nor the supplier can tell from the responses which figure is the comparable one.
A specification that leaves any of these open produces responses that cannot be compared, because two suppliers have priced two different projects. The most common example is a fall height that is stated as a maximum rather than a fixed figure, so one supplier prices the equipment at 2.4 metres and another at 1.8 metres, and the surfacing that follows is priced differently in each response. The second example is a materials clause written as a performance description rather than a specification, so a supplier who offers a lower grade answers a different question. Both are avoidable, and both are far cheaper to fix before the tender is issued than to correct through a clarification notice.

The documentation schedule is the list of evidence the authority requires with the response, and it is what makes the evaluation verifiable rather than a matter of opinion. For playground equipment it typically includes the test certificates for the specific product families being supplied, with the certificate number and the issuing body named so that the authority can verify it, and the factory inspection reports. It includes the product liability insurance certificate, with the limit, the territory and the expiry date stated. It includes the manufacturing capacity evidence, which is frequently a statement of the production lines and the annual output. And it includes references, usually two or three, with the site, the date and the scope of the work, so that the authority can check them rather than take them on trust.
The schedule also determines what a supplier has to keep ready, and this is where a buyer can plan ahead. A certificate that takes three weeks to obtain, or a reference from a project that has to be arranged with a customer, will delay a response. Suppliers who work on public tenders keep a documentation pack current for this reason, and a buyer who names the required documents precisely gets responses that can be compared without a clarification round. It is worth checking the schedule against the closing date, because a requirement that cannot realistically be met in the time allowed will narrow the field of bidders more than the authority intends.
The evaluation criteria are the part of the tender that most often decides the result and the part most often written too loosely to survive a challenge. A typical published split for a playground contract allocates a percentage to technical compliance, a percentage to the price and a percentage to quality measures such as references, warranty and delivery programme. The criteria must be stated in the tender documents, must be capable of being scored by two evaluators who reach the same result, and must not allow a discretionary judgement that cannot be explained. A clause that awards points for an attractive design or for a strong relationship with the authority is precisely the kind of clause that gets a tender reopened, because it cannot be applied consistently.
The table below sets out the weighting structure that is commonly published for a playground contract, with the review question written as a question because that is the form that has to be answered in the tender documents before the tender opens. The percentages are indicative rather than fixed, and the weight on the price depends on whether the authority is required to take the lowest compliant price or is permitted to evaluate on a weighted basis. What the table is for is to show that each criterion has to be stated with a weight and a scoring rule, so that the outcome can be explained to a bidder who asks why it lost.
| Evaluation criterion | Indicative weighting | Review question to settle before the tender opens |
|---|---|---|
| Technical compliance with the specification | 40 to 60 percent | Is each requirement pass or fail, or scored, and what happens to a response that fails a mandatory clause? |
| Price against the commercial response | 30 to 50 percent | Are the foundations and the surfacing inside the quoted scope, so that the prices being compared are the same scope? |
| References from comparable installations | 5 to 10 percent | How many references, of what type, and how are they verified with the named contact? |
| Warranty and after-sales commitment | 5 to 10 percent | What is the minimum warranty period on the structure, and how are the wear parts handled? |
| Delivery programme and manufacturing capacity | 5 to 10 percent | Can the stated programme be met against the required opening date, and what evidence supports it? |
| Insurance, documentation and operating file | Mandatory pass or fail | Are the required certificates, limits and delivery dates stated precisely enough to be assessed without a clarification round? |
Price is usually scored on the commercial response rather than on the headline total, and the reason is that the headline total depends heavily on assumptions that the specification may not have settled. Two bids for the same equipment can differ by a wide margin because one includes the surfacing and one treats it as a separate contract, or because one includes the foundations and the other assumes the authority has already built the bases. The tender document has to state clearly which of these are in scope. Where the scope is stated, the scoring is straightforward; where it is not, the lowest price on the page is frequently not the lowest compliant price, and the authority ends up defending a decision that was never properly tested.

Public contracts carry insurance requirements that a private purchase usually does not, and a supplier who has not worked on public tenders can be caught out by them. The standard requirement is product liability insurance with a stated minimum limit, which in the United States is commonly 1 million US dollars per occurrence and in Europe is commonly 2 million euro, together with cover in the territory of installation. The certificate has to name the insured legal entity, and the entity named on the certificate has to be the entity named on the contract, which is not always the trading name that appears on the quotation. Public authorities also commonly require the supplier to hold cover for the whole contract period and to accept the contract conditions on insurance, warranty, defect correction and site conduct.
The warranty position is equally specific. A public contract usually requires a stated minimum warranty period on the structure, which is commonly 10 years against a requirement for 5 years, with separate periods for the components that wear, such as the surfacing, the bearings and the rope. It also requires the supplier to accept responsibility for correcting defects found at handover, on a stated timescale, and for supplying the spare parts to do it at a price agreed in advance. These requirements are reasonable, but they change the cost of a quotation, so a buyer who wants comparable prices should state them in the tender documents rather than negotiating them after the award.
The site information pack is where the foundations are decided, and it is the section where the buyer carries the responsibility. It should contain the ground investigation report, which for a playground specifies the design category of the post foundations, and the site plan with the fall zones drawn, because the equipment positions and the surfacing areas are determined by the fall heights rather than by the layout that looks most attractive on the plan. It should contain the drainage information, since a site with an existing drainage problem will otherwise be priced with a drainage assumption that turns out to be wrong. And it should contain the utilities information, including the location of any overhead lines, which affects both the installation method and the safety of the erection team.
Where the buyer cannot supply the ground investigation, the specification should say so, and the contract should allocate the risk explicitly. The common arrangement is that the supplier prices a standard foundation for a stated assumed category and that the authority carries the cost of the difference if the actual ground requires more. This is workable, but it has to be written down, because a foundation priced on an assumed category that turns out to be wrong can change the total cost of the contract by a significant amount. A buyer who has the ground investigation carried out before the tender is issued removes the largest single source of variation in the final price.

The handover stage is where the contract is closed, and the specification should describe it in enough detail to be tested. It should state who inspects the installation, on what basis the conformity is assessed against the certificate that accompanied the equipment, and what the site condition must be at handover, which includes the surfacing being fully cured and the fall zones clear. It should state the defect list process, in which the authority and the supplier walk the site together and record each defect against the element and the location, and it should state the timescale for correcting them, which is commonly between 7 and 30 days depending on the defect.
It should also state what is required for final acceptance, which usually means the defect list is closed, the operating file is delivered and the insurance certificate is provided for the warranty period. The operating file is the document that carries the site forward, and for a playground it contains the installation and handover documentation, the current test evidence for the equipment, the surfacing specification with its tested value, the warranty terms and the maintenance schedule. Asking for it as a deliverable in the tender documents, rather than assembling it after handover, is what makes it complete, because the inspection history only exists if it was written down from the first day.

No. In most public procurement rules the award has to be made against the published criteria, and the price is one of them rather than the whole of them. The usual approach is to identify the compliant responses, exclude any that fail a mandatory requirement, and then score the remainder. Accepting the lowest price regardless of the technical response breaches the process and is normally the first thing challenged if the award is disputed. A buyer who wants the lowest price should make price the dominant weighted criterion, and state that weighting in the tender documents, rather than leaving it to be argued afterwards.
Not necessarily. What is usually required is test evidence for the specific products being supplied, rather than a general factory certificate, and the distinction matters. A certificate for one product family does not cover a different family, and a company certificate that assesses the quality management system is not a product conformity evidence. The tender documents should state the evidence required for each product group, and a supplier should confirm that the evidence covers every item in its response rather than a representative sample. Where a new product line has no test certificate yet, that needs to be resolved before the tender rather than after the award.
It depends on how the contract allocates it, and the allocation has to be stated rather than assumed. The most common arrangement for a supplier-supplied contract is that the supplier designs and installs the foundations, on the basis of the ground information supplied in the site information pack. Where the ground investigation is missing or where the actual ground is worse than the assumed category, the contract normally provides for a variation at a stated rate. A buyer who wants the risk removed entirely should commission the ground investigation and require the foundations to be designed for the confirmed conditions, which raises the tender price but removes the largest variable from the final account.
Between 8 and 16 weeks is the usual range for a playground contract, and most of that time is in the process rather than in the equipment. The notice period and the tender period itself account for 4 to 8 weeks, the evaluation and the approval of the award take 2 to 4 weeks, and the contract preparation and signature take 2 to 4 weeks. The manufacturing and delivery period then runs from the contract, not from the award, and it is typically 8 to 12 weeks for a custom playground. A buyer planning a school or a public opening should work back from the opening date rather than from the tender date, because the site work and the surfacing curing also have to fit between delivery and opening.

The most common mistake in a playground tender is a specification that is written as a wish list rather than as a set of requirements that can be demonstrated. A requirement written as a general adjective, such as a product of superior build quality, cannot be scored, and a supplier who answers it cannot be compared with one who answers it differently. The second most common mistake is leaving the site information incomplete, particularly the ground investigation and the fall zone layout, which produces quotations that cannot be compared and a final price that is uncertain. The third is a documentation schedule that is inconsistent with the closing date, which narrows the field of bidders more than the authority intended. The fourth is failing to state whether the surfacing and the foundations are in scope, which is the single most common cause of a low bid turning out not to be the low compliant bid.
A fifth mistake, on the supplier side, is answering the specification with a description of the product rather than with the evidence for it. A response that states the coating is durable when the schedule asks for the coating class and its film thickness in micrometres will be scored as incomplete, however good the product is. The practical answer is to answer each schedule line with the value and the document that evidences it. Buyers who write the schedule this way get responses that are directly comparable, and suppliers who answer it this way avoid a clarification round that delays the whole process by two to three weeks.
Standard and mandatory clauses stated, with the parts of the standard that are requirements rather than guidance identified
Fall heights, age ranges and equipment positions fixed, with the fall zones drawn on the site plan
Coating system stated as substrate, pretreatment and coating, with film thickness in micrometres
Impact-absorbing surfacing specified with its tested value at the maximum site temperature
Evaluation criteria published with weights, each capable of being scored consistently by two evaluators
Documentation schedule checked against the closing date so the evidence can realistically be produced
Product liability insurance limit, territory and validity stated in the tender documents
Ground investigation, drainage and utility information issued, or the risk allocation stated in writing
Scope confirmed for foundations, surfacing, installation, inspection and the operating file
Handover inspection, defect list timescale and final acceptance conditions defined
A playground tender is not a price comparison exercise with a compliance check at the end. It is a process in which the specification, the documentation schedule and the evaluation criteria together decide the result, and every one of those three is written before any supplier responds. A buyer who treats that drafting stage as the most important part of the procurement gets quotations that can be compared, foundations that are priced against real ground conditions, and an equipment selection that can be defended long after the contract is signed.
Send the draft specification and the documentation schedule through the NUUTOO project enquiry page before the tender is issued, and ask for a written response to each requirement. The value of that step is that the requirements which cannot be met are found out while they can still be changed, rather than after the award when the only available remedy is a clarification notice or an appeal.
