At Station 50 +50.55, 39.23 LT the curb and gutter is moving west approximately 3' -4'. The proposed change adds a new concrete inlet #11 (with rectangular vaned grate) at Station 50 +54.90 (49.03' Lt) to accommodate the shift in curb and gutter along with additional ductlile iron storm sewer pipe 8 in. diam. A new concrete inlet is necessary to capture and route the runoff into the existing drainage system (which is being maintained in its current alignment). Associated quantities are adjusted. Refer to the attached revised Drawings No. 16 and No. 19 for the proposed changes (revised 7/12/12). Contract Change: Add concrete inlet #11 (with rectangular vaned grate) and 10 LF of 8" diameter ductile iron pipe from the new catch basin to the existing catch basin at Station 50 +55.55 (39.23' Lt). Modify Drawings No. 16 (Roadway Plan) and No. 19 (Roadway Profile) as shown (revised 7/12/12). Add the following quantities to bid item plan quantities in the schedule of prices.
