Supplies and services shall be purchased by or furnished to a city department, agency,
board, commission, or authority by the manager of general services upon requisition
to the director, or pursuant to procedures prescribed by him. Requisitions shall be
approved by the head or an authorized representative of the head of the department,
agency, board, commission or authority by their signature thereon; or by electronic
transmission of the requisition to the manager of general services. The approval shall
affirm that there is sufficient unencumbered balance existing in the appropriation
of the department, agency, board, commission or authority requesting the purchase
to pay for the purchase. The electronic transmission of the requisition shall constitute
an approval if the electronic approval is affirmed as appropriate and secure by the
manager of general services. The manager of general services shall prescribe the form,
contents, number and distribution of requisitions. The manager of general services
shall examine each requisition and may revise it as to quality, or estimated cost;
but revision as to quality shall be in accordance with the standards and specifications,
if any, established pursuant to this division. A requisition may not be required for
purchases made pursuant to a bidder's proposal or request for proposal issued by the
department for supplies, equipment, or personal property which are required and may
be utilized by one or more department, agency, board, commission or authority with
a term exceeding ninety (90) days. No department, agency, board, commission or authority
may utilize such a contract unless there is sufficient unencumbered balance existing
in its appropriation to pay for the purchase.
