When a contract has been let for the work required by any local or municipal improvement by the Director of Purchasing, and said Director of Purchasing thereafter, pursuant to requisition of the Commissioner of Environmental Services, authorizes additions to the work or materials or changes in the plans and specifications covering the work, it is hereby declared to be impracticable to have such extra or unspecified work done or materials furnished by competitive contract. The Director of Purchasing is directed when so requisitioned by the Commissioner of Environmental Services to have such work done or materials furnished without competition, provided the additional cost does not increase the total anticipated expenditure, where the improvement is a local improvement, in excess of the ordinance estimate furnished the Council by the Commissioner of Environmental Services in accordance with Section 154 of a local law adopted by the Common Council on July 28, 1925, approved by the electorate of the City of Rochester on November 3, 1925, as amended.
