Executive Summary
A developer signing off a date palm package has two clocks running, not one. Non-structural and fit-out defects sit inside a defects liability period that runs about 12 months from handover, while structural elements such as the base plate, the anchoring and the core carry a far longer statutory exposure that a contract cannot waive. Most of the loss in between is procedural: a snag list submitted late, a colour baseline never recorded, a cleaning regime that was promised but never written into the maintenance contract. Fix the three documents and the DLP becomes routine administration instead of a dispute.

1. What Goes Wrong Without This
An artificial tree package looks like one of the simplest items on a fit-out schedule. There is no plant establishment, no irrigation dependence, no growth risk. That simplicity is exactly why its handover is usually under-documented, and why the cost lands on the developer eighteen months later.
The snag list arrives after the leverage is gone. A tree is snagged at handover by walking to it and looking at it. Once the atrium is carpeted, the seating installed and the lobby in daily use, the same defect is an occupied-space work order with access restrictions, protection requirements and an argument about who damaged what. Contract practice in the region puts the strongest position on a written defect list submitted within about 30 days of handover, with rectification commonly falling into a 30-90 day window while access is still straightforward.
Nothing recorded the colour. The single most common dispute on an artificial tree package is colour, and it cannot be resolved after the fact. If a replaced section is not from the same production batch as the tree it is fitted into, the join is visible from the mezzanine, and the argument becomes whether the drift is a material defect or normal aging. A supplier cannot win that argument and neither can the developer, because neither side holds a dated reference. One photograph and one retained sample per specimen at handover would have settled it.
The warranty was conditioned on maintenance nobody performed. Defect cover for a fit-out item is a workmanship and material warranty; it stops covering deterioration caused by the owner's failure to maintain the installation to the agreed programme. For an outdoor specimen that means cleaning and, where specified, annual inspection of the fixings. If the cleaning interval never made it into the facilities management scope, the first sign of surface degradation becomes a contested claim rather than a call-out.
Nobody knows what is installed. A tree package arrives as pieces: trunk lengths, a crown, a planter, a base plate, a fixing set. If the handover pack contains a photograph of a finished lobby and no register, then a defect on one section in year two cannot be traced to a drawing, a batch or a piece number. The survey team has to reverse-engineer what was installed before anyone can order a replacement, and the replacement then arrives with a lead time the operating budget never anticipated.
The retention is released with the tree package still open. Retention held against completion is released on a schedule, and a tree defect that is still open at release converts into a direct cost. Because the item is small relative to the overall package, it is the easiest line to lose track of, and the most expensive one to rediscover later.
The financial shape of the failure is consistent: a defect that costs a few hours of factory time if it is closed at handover becomes a full replacement plus freight plus access if it surfaces after the DLP window and after the space is in use.
2. The Decision Framework
Ten decisions, all of them answerable at contract and handover stage rather than later.
1. Name the interface in the contract. On most projects the tree package is supplied by a specialist and installed by a landscape or fit-out contractor. The base plate, the fixing into the slab, the planter surround and the electrical supply to any uplighting sit on the boundary. Write down which party owns each, because an interface defect is the one category both parties can decline. 2. Require a register, not a photograph. Per specimen: product reference, height, piece count, base-plate drawing number, production batch or colour code, and the piece numbers that are stamped or labelled on the components. 3. Take a dated condition baseline. Photograph every specimen at handover, before the space is occupied, from a fixed position. Record the lighting condition and the surface cleanliness, because a baseline taken after the first wash is not a baseline. 4. Retain a physical colour sample. A labelled swatch of the foliage batch, held at the project rather than at the factory. This is what turns a colour dispute into a five-minute comparison. 5. Classify every snag into four buckets. An acceptance item (must be corrected before final acceptance), a warranty item (coverable after acceptance provided maintenance conditions were met), an ordinary maintenance item, and an owner decision (a change, an access restriction, a cost). Each has a different owner, a different billing rule and a different clock. 6. Confirm when the DLP actually starts. Some contracts start it at the handover certificate, others at the completion certificate covering the whole development. On a phased masterplan a specimen installed in the first phase can exit its defects period before the retail podium opens. 7. Put the cleaning regime in the contract, not the brochure. Exposure class, interval and permitted chemistry, with the interval written to the same schedule the maintenance provider is priced against. 8. Order the spares at handover. A replacement section is a factory order, not a stock item. Spares held at the project cost a pallet position; spares ordered after a failure cost the full lead time. 9. Establish who owns the tooling and the drawings. For a bespoke specimen, if the drawings and moulds belong to a supplier who may not exist in five years, a section replacement becomes a new design exercise. 10. Set a response time, in writing. A specimen in a hotel lobby or a mall atrium is a guest-facing asset. The response standard the developer needs is the one the operator will actually hold them to.
The framework reduces to a single test that is worth applying to the whole package before handover: could a new facilities team, with no contact with the installation crew, understand what is installed, how it should be cleaned, and where the spare parts come from, using only the documents handed over? If not, the package is not closed out.

3. Numbers, Tiers and Timelines
| Item | Typical range or tier | What drives it | Decision rule |
|---|---|---|---|
| Defects liability period, non-structural | 12 months from handover | Contract form and jurisdiction | Diarise the tree package review at month 10, not month 12 |
| Structural / decennial exposure | 10 years from handover, not waivable by contract | Statutory regime | Base plates, anchoring and fixings are documented with calculations and kept in the project archive |
| Snag list submission window | 30 days from handover for the strongest position | Contract notice clause | Complete the per-specimen walk while access is still unrestricted |
| Rectification window | 30-90 days for standard defects | Defect severity and site access | Close acceptance items before final acceptance, not after opening |
| Retention / security held | 5% of project value for 12 months (Dubai practice) | Contract and escrow rules | Confirm the tree package is closed before release is triggered |
| Spares held at project | 3-5% of foliage panels plus one crown section on exposed specimens | Height, visibility, exposure class | Buy at handover; a spare is cheaper than access equipment plus freight |
| Replacement lead time | 25-35 days standard height; 45-60 days above 6 m | Factory schedule and mould availability | Any defect that survives the DLP converts into this lead time |
| Cleaning interval by exposure | 3-4 weeks coastal, 6-8 weeks rooftop or inland desert, 10-12 weeks sheltered | Site exposure class | Write the interval into the FM scope as a warranty condition |
Two rows in that table do the most work. The 30-day snag window is where the developer holds all the leverage, and the cleaning interval is the only item on the list that the developer can lose by simply not writing it down.
4. How to Apply It to a Live Project
Tender and award. Fix the contract split now: which party supplies the base plate and the fixing set, which party connects any uplighting, and which party owns the surface finish of the planter. Add the register requirement and the colour sample retention to the specification, not to the purchase order.
Sample and mock-up stage. Approve a physical specimen, not a render, and record the batch or colour code at approval. This is the reference against which every later colour question is decided, and it costs one factory sample.
Shop drawings. Confirm the engineering calculations for the base plate and the anchoring arrangement are issued with the drawings, and that the drawing set identifies every piece that will be labelled on site. On a crown-heavy specimen such as the atrium ficus the set also has to identify the crown suspension points, because those are the pieces most likely to need replacement while the specimen is in service. This is where a later replacement stops being a survey exercise.
Production and shipment. Ask for the piece-number list against the packing list before dispatch. A crate whose contents cannot be reconciled to the register is the reason a single damaged section turns into a whole-specimen claim.
Installation and commissioning. Photograph the base plate before the planter surround or paving closes over it, and photograph each specimen in its finished position under the baseline conditions defined earlier. Those two sets of images cover almost every dispute that follows, because they show the condition of the concealed work and the appearance at acceptance.
Snag walk and handover. Walk every specimen, not just the ones that look wrong, and classify each item into the four buckets. Submit the list inside the 30-day window, with the register, the baseline photographs, the retained colour sample and the spare parts schedule.
Defects liability period. Review open items at month 10 rather than month 12, because a rectification order placed at month 12 lands outside the period it was meant to cover. Confirm the cleaning records exist, since they are the evidence that the maintenance condition on the warranty was met.
Asset handover to operations. Transfer the register, the cleaning schedule and the spare parts position to the operator or the FM provider, and note the date. From that point the tree package behaves like any other installed asset, which is the outcome the whole process is designed to produce - whether the specimen stands in a hotel atrium, a mall concourse, or an outdoor mall landscaping zone.

5. Commercial Contractor FAQs
Q: Does a one-year defects liability period cover an artificial tree?
A: For non-structural defects, yes, in the sense that a workmanship or material failure reported inside the period is rectified at the supplier's cost. What it does not cover is deterioration caused by the owner's failure to maintain the installation to the agreed programme, and it does not extend to the anchoring and base plate, which sit in the longer statutory structural category. The practical consequence is that the tree package needs two lines in the project risk register, not one.
Q: The tree was damaged by another trade during the fit-out. Who pays?
A: The party that caused it, but only if the damage is documented against a baseline. This is why the dated condition photograph at installation matters more than any other single record on the package: it separates damage that existed at completion from damage that happened during the fit-out and from damage that happened after occupation. Without it, the three are indistinguishable and the supplier ends up absorbing a loss they did not cause.
Q: What belongs in the handover pack for a tree package?
A: Seven items: the register of installed specimens with piece numbers, the as-built drawings and the base plate template, the fire and UV certificates covering the delivered construction, the colour or batch reference with the retained sample, the cleaning specification with the interval and permitted chemistry, the spare parts schedule with quantities and location, and the named contacts with the response standard. A package that contains only a finished photograph is not a handover.
Q: Do spares really need to be bought at handover?
A: Yes, for any specimen over about 6 m or any specimen in a guest-facing position. Spares at 3-5% of foliage panels plus one crown section are a small pallet, and they can be held in the building's own store. A replacement ordered after a failure takes 25-35 days at a standard height and 45-60 days above 6 m, plus freight - which means a visible defect in a lobby stays visible for two months while the operator answers questions about it. The two figures are not comparable, which is the whole argument.
Conclusion: Close the package while access, leverage and crew are still on site
The tree package is small enough to be overlooked at handover and visible enough that every later problem is the developer's problem. Record the baseline, take the colour sample, classify the snags, buy the spares and write the cleaning interval into the maintenance contract - five actions, all of them cheaper at handover than at any point afterwards.
Our engineering team issues the documentation a developer actually needs at closeout: a per-specimen register with piece numbers, as-built drawings, base plate templates, fire and UV certificates, a colour reference sample and a spare parts schedule sized to the project. Send the specimen schedule and the exposure of each position, and we will return the closeout pack in the format the project register expects.
