Project Title: Standardization of Special Provisions and Determination of Unit Costs for Utility Installations
URL: http://tti.tamu.edu/documents/0-4998-2.pdf
16. Abstract
Because of the lack of standard utility installation construction specifications at the Texas Department of
Transportation (TxDOT), many different versions of utility installation special specifications and special
provisions exist around the state. Those specifications and provisions frequently contain very similar
information. Closely related to the need to standardize construction specifications for utility installations is
the need to standardize methodologies and procedures for the determination of utility relocation costs. In
practice, there is a wide range of ways in which utility companies submit utility relocation costs for
reimbursement. This lack of standardization translates into difficulties such as how to verify the validity of
the data utility companies provide and how to adequately prepare for audits and other internal and external
inquiries.
Report 0-4998-1, A Unit Cost and Construction Specification Framework for Utility Installations, describes
a prototype framework of construction specifications and corresponding unit cost work items for utility
installations at TxDOT and recommendations on how to implement that framework in Texas. This report
complements Report 0-4998-1 by providing a set of specification requirements for water and sanitary sewer
utility installations that could be used to prepare the construction specifications. The requirements for each
specification include a summary table that outlines the main characteristics of the proposed specification and
provides a listing of bid items, subsidiary items, and units of measurement, followed by a list of specification
requirements that follow TxDOT’s 2004 standard construction specification style.
