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 162 | CHAPTER TWELVE 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. TOWN OF PALM BEACH
