The additional work includes the following tasks. 1. Hopkins Court Drainage Demon — The approved Conceptual Design Report for this project recommends removal of the existing curb opening in Hopkins Ct. and construction of a new 10-foot inlet at the low point along the curb line and 150 linear feet of 21-inch RCP from the new inlet to the existing concrete flume. Our principal contract does not include design services for this work. This amendment is for the design and preparation of construction documents for this work. It is anticipated that this design will be bid along with the Hammond Street Drainage Improvements project and will not be advertised and bid as a separate project. The following is a summary of additional tasks (See attached task breakdown): a. Meetings -Attend one (1) neighborhood meeting b. Surveys - Subsurface Utility Engineering (Quality Level B) for at least 3 utilities in general accordance with the recommended practice and procedures described in ASCE Publication CD/ASCE 38-02 (Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data). c. Easement Parcels 1) Drainage Easements (2) 2) Temporary Right of Entry Agreements (2) d.
