Lowest price technically acceptable (LPTA) is a procurement method in which proposals are first checked against minimum technical requirements, and the contract goes to the lowest-priced proposal that passes. No credit is given for exceeding the minimum.
LPTA is defined in U.S. federal acquisition rules and widely copied by state and local agencies. It works when requirements are well defined and quality differences do not matter, such as buying standard commodities. It works poorly when experience, design and long-term support drive results.
LPTA in parking procurement
- Where it can fit. Commodity supplies, simple maintenance services, standard equipment with clear specifications.
- Where it struggles. PARCS, software platforms, operations contracts and design services, where the cheapest acceptable proposal can cost more over the life of the system. See life-cycle cost.
- The alternative. Best value procurement weighs qualifications, approach and price together.
- Writing better minimums. If LPTA is required, the technical minimums must capture what actually matters, including integration, data ownership and support.
The Parkonomics view
LPTA buys exactly what the specification asked for at the lowest price. For parking technology, the specification is rarely good enough to make that a bargain.
