ENGINEERING SERVICES
For the 2017 construction season, the City has approved a reconstruction project in the
Minnewashta Manor neighborhood (Project#16-01) and proposed a rehabilitation project on
Park Road (Project#16-04). 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.
