Engineering and Constructability - Anna Maijala - anna.maijala@austintexas.gov Release of this application does not constitute a verification of all data, information, and calculations supplied by the applicant. The engineer of record is solely responsible for the completeness, accuracy, and adequacy of his/her submittal, whether or not the application is reviewed for code compliance by city engineers. Transportation Engineering Group will be renamed to Land Review Engineering and Constructability Review Group. The City of Austin – Development Services (DSD) is not able to revise our review group title until the new version of our database software - AMANDA is fully rolled out. DSD has deemed it to be beneficial to implement a “Constructability” review for all projects submitted, whether located in the City of Austin or the ETJ. The Public Works Department along with other CoA utilities have been experiencing a large amount of construction re-work due to actual field conditions differing from the design construction drawings. Since the constructability review will be looking at multiple disciplines, there is a potential that our review comments may or may not be commented on by other review groups. Our constructability review is conducted to help resolve potential construction issues during the design phase of the project. This review is being done to benefit all involved in the construction project – Developer, Engineer of Record, Contractor and the City of Austin by having another set of eyes reviewing for common constructability issues. Constructability review can lead to enhanced quality, a reduction in change orders and information requests, cost savings, and optimized schedules which reduce the overall time of construction. EC1: An engineer’s cost estimate is required for all proposed subdivision improvements for which fiscal is required such as streets, detention and water quality ponds, drainage, sidewalks, erosion and sedimentation controls, restoration, water and wastewater, etc. Provide an engineer’s cost estimate for roadway construction for the portion of new Mountain Shadows Drive ROW being dedicated by this plat. 25-1-112 “FISCAL SECURITY” END OF REPORT
