Due to the time demands of these projects, the City Engineering Department does not have sufficient staff time to perform construction observation for the 17-01 Lake Susan Hills Street Rehabilitation project. Staff proposes contracting with a consultant for engineering services for this project. The engineering services would include construction observation/oversight and as-built surveying work after the project is completed. Staff evaluated the hourly rate for construction observation and as-built surveying from two companies: Hansen Thorp Pellinen Olson, Inc. (HTPO) and Kimley-Horn &Associates. Hansen Thorp Kimley-Horn & Pellinen Olson, Inc. Associates Cost for 255 Hours of Construction $31,365.00 $34,425.00 Observation (at$123.00/hour) (at $123/hour) (at $135/hour) $1,840.00 $1,072.94 Cost for 16 Hours of Surveying (at $115/hour) (at $67.06/hour) Total of Cost for Engineering Services $33,205.00 $35,497.94 The proposed HTPO team has previously provided engineering services to the City of Chanhassen and their work in Chanhassen and other communities has been satisfactory. The consultant contract will be a time and materials based work not-to-exceed amount totaling $33,205.00 for all construction observation and surveying work. As with all engineering contracts, the consultant must submit periodic invoices that staff will review before processing. The consultant will be required to submit timesheets verifying the hours worked on the project and expense sheets. Staff will review the invoices and expense sheets for accuracy and conformance to the contract.
