Beneficial Use Before Provisional Acceptance in Warehouse Automation Projects
Owners facing peak season, lease commencement, or customer commitments often want to begin live operations on individual aisles, sorter lines, or zones before the system reaches provisional acceptance. Most warehouse automation contracts, however, tie the consequences that matter to provisional acceptance of the whole system: delay liquidated damages stop, the warranty begins, and risk and title pass to the owner. Accordingly, early operation leaves the supplier finishing the system around live production, at added cost and schedule risk, while carrying the risks of an operating facility without the protections provisional acceptance was designed to provide. The owner, meanwhile, enjoys the use of the work and continues to accrue liquidated damages meant to compensate for its absence.
Acceptance by Conduct
When a contract is predominantly for the sale of goods, Article 2 of the Uniform Commercial Code may treat the owner's use of equipment as acceptance, because use is conduct inconsistent with the seller's ownership. Courts differ, however, on whether a mixed contract for equipment and installation falls under Article 2 at all. Rather than leave the question to default rules, the contract should provide that sustained use of a defined portion of the system for a stated period or use of the work for an operational purpose, without the supplier’s written permission, constitutes provisional acceptance of that portion.
Risk of Loss, Title, and Insurance
Builder's risk policies commonly end or restrict coverage once the insured property is occupied or put to its intended use, and the owner's operating property policy may not respond to equipment that remains at the supplier's risk until provisional acceptance. Equipment in production can therefore fall between the two policies, so beneficial use should transfer care, custody, and risk of loss for the portion in use, along with title where title otherwise passes at go-live, and the owner should confirm that its property coverage attaches on that date.
Warranty Start
When the warranty runs from provisional acceptance of the entire system, a portion placed in production months earlier accumulates wear and operating hours that the warranty period never counts. Meanwhile, the supplier's own vendor warranties, many of which run from shipment or installation, continue to expire. The warranty for each portion should begin on the earlier of provisional acceptance or beneficial use of that portion, and an outside date measured from delivery should prevent owner-driven delays in go-live from extending the supplier's obligations indefinitely.
Wear, Damage, and Control of the System
Owner operation before go-live produces wear, jams, damaged totes and carriers, and occasional interlock overrides. The contract should excuse the supplier from presenting the used portion for provisional acceptance testing in new condition, exclude damage caused by owner operation from the warranty and the supplier's scope, and require the owner to follow the supplier's operating procedures. It should also allocate lockout and tagout authority and guarantee the supplier defined commissioning windows. Without those windows, production demands will consume the access the supplier needs to bring the remaining portions to go-live, and the resulting delay will be charged against the supplier's schedule. Alternatively, the supplier may want to require that any beneficial use of the work constitutes acceptance of the whole, in order to ensure that the owner is properly motivated to cooperate with the supplier toward reaching completion.
Delay Damages, Payment, and Testing
An owner running production on part of the system already has the benefit that delay damages are meant to replace, so delay damages should stop accruing, at least in proportion to the value of the portion in use. Beneficial use should also release the provisional acceptance payment for that portion. Because live production before go-live rarely reflects the design basis, the contract should bar the owner from using production data to challenge the system's performance in the provisional acceptance test. None of this should accelerate final completion, and punch list items on the portion in use should remain final completion work rather than grounds to withhold provisional acceptance.
A short beneficial use clause can prevent most of these disputes. It should define the trigger, divide the system into acceptance portions, and attach delay damages, warranty commencement, risk of loss, title, and payment to each portion at the point of production use.
