I. General Contract Change Order No. 9 T h e original specifications provided for the use of either of the following mortars for face brickwork and for common brickwork above grade, excepting for load bearing piers and for parapet walls: Class "A" Cement-lime Mortar—composed of one part Portland cement, one part hydrated lime, or equivalent amount of lime putty, and not more than 6 parts sand, or Medusa-Mix mortar in I : 3 proportion. Class "B" Natural Cement Mortar—I part bricklayers natural cement of approved brand to which shall be added 3 parts lake sand, thoroughly mixed. It is now agreed between the parties to the contract that better brickwork for this particular project will result from the use of the following mortar, which will be substituted for original brick mortar specification: "Mortar for brickwork, except for parapet walls, shall be mixed in the proportion of 1 part Portland cement, 3 parts lime putty, and not more than 9 parts sand. Lime putty shall consist of lump lime thoroughly slaked in water before sanding and shall be allowed to stand not less than 24 hours after sanding. Mortar shall be mixed with Portland cement in an approved type of power-operated mortar mixer. Materials shall be measured in accordance with the following procedure:—The exact proportions of lime putty and sand required for proper workability shall be determined by trial batches made at the start of brickwork and at later periods as required, under the supervision of the Architect or Owner's representative. F r o m the volume of sand thus determined, the amount of Portland cement, which shall be equal to i/oth of the volume of sand, shall be determined. T h e quantities of material delivered for mortar shall be recorded in order to check the specified cement-sand ratio." For parapet walls Class "C" mortar shall be used as originally specified. This involves no change in contract price, nor increase in time required to complete the project. This replaces Change Order No. 9 (General Contract) presented June 29, 1936 (Minutes, page 879), but not approved.

On motion of Mr. Barr, Change Order No. 9 (General Contract) was approved.
