y y It can be expected that cost variations may occur
throughout the life of the program based on market
conditions, labor and material price fluctuations, and other
factors. Kimley-Horn has no control over the cost of labor,
materials, equipment, or over the Contractor’s methods of
determining prices or over competitive bidding or market
conditions. Opinions of probable costs provided herein
are based on the information known to Kimley-Horn at
this time and represent only Kimley‑Horn’s judgment as a
design professional familiar with the construction industry.
Kimley-Horn cannot and does not guarantee that proposals,
bids, or actual construction costs will not vary from its
opinions of probable costs.
12.7.2 Existing Conditions
y y Allowances for repair/replacement of service entrances on
private property not meeting existing building codes should
be included in the project to maintain the project schedule.
These types of costs, while expected to be a rare occurrence,
are expected to be reimbursed to the program by the private
property owner and therefore have not been included in
this opinion of cost.
y y In many locations throughout the Town, electric and
communications services originate from a rear property

easement. To be compliant with current utility company
standards, these services will be converted to a front street
location under this program.
y y This opinion of cost has assumed 10% of the residential
and commercial services are already served from a front
street location and do not require new underground
conduits to be installed on private property. New
underground infrastructure would connect to the existing
conduits at the existing front street location.
y y It is assumed that new utility infrastructure related to the
conversion process will be installed in public rights of way
and easements. It is further assumed that this infrastructure
will be installed in a manner that minimizes relocation of
existing utilities in these same locations. These potential
impacts cannot be accurately quantified at this time and are
therefore not included in this opinion of probable cost.
12.7.3 Construction Methods: Directional Bore vs.
Open Trenching
Conduit for electrical and cable/telephone infrastructure are
typically installed using open-cut trenching or directional boring.
Costs for these methods for installation within a typical residential
area within the Town were analyzed to determine the most cost-
effective installation method.
