Overbundled requirements frequently suffer from very vague requirements and work statements, particularly in service contracts. In service contracts, the CLIN structure is priced on a per person per hour basis rather than on the service work deliverables themselves. Government or contractor ability to prepare cost or price estimates for vague work statements is severely limited; accordingly, the Government will negotiate a labor rate, number of people and individual qualifications for the requirement given that is the only feasible way to get an idea of cost. However, use of per person/per hour pricing for services is a poor contracting practice given the Government retains virtually all performance, cost and schedule risk given the contractor has fully performed under the CLIN statement when they provide the qualified body, rather than providing the needed service. One could argue that a CLIN statement which overbundles work in even a well written work statement and prices the work on a per person/per hour basis with limits on the numbers of person and types of qualifications the contractor can use is in contradiction to the work statement given the means the Government has asked the contractor to price the contract bears no relationship to the actual work itself and the Government is directing the contractor on how to execute the requirement – thus interfering with contractor performance and a sign of an employee-employer relationship rather than an independent contracting relationship. Also, the CLIN structure which prices on a per person basis or per hour basis generally pays for such persons on an annual basis rather than merely for the service on an a la carte or as-needed basis, therefore driving up costs in many cases. Pricing on a per person or per hour basis is a sign that a contract likely also qualifies as a personal services contract under FAR Part 37 – technically violating at least the spirit, if not the letter, of the Classification Act and FAR Part 37 except in specific circumstances and with specific determinations and findings.
