SUE Subsurface Utility Engineering

Non-Project-Specific Consultant Contract Information

About

The CDOT Utilities Program has established two SUE NPS consultant contracts for CDOT personnel to use in association with highway projects. The services that can be provided through either of these contracts include:

  • Preliminary utility information gathering;
  • Visual observation and surveying of above-ground utility facilities;
  • Surface marking of buried utilities;
  • Exposing and surveying the location of buried utility facilities;
  • Utility facility mapping and CADD drawings;
  • Utility relocation planning and design.

The contracts incorporate the SUE information Quality Levels of D through A that are described in ASCE standard "ASCE C-I 38-02, Standard Guidelines for the Collection and Depiction of Existing Subsurface Utility Data". Each quality level represents an improvement over the previous level (D the lowest, A the highest). Click on the quality levels tab above for definitions.

SUE Quality Levels

Quality Level D ("QL D") information comes solely from existing utility records. It may provide an overall "feel" for the congestion of utilities, but it is often highly limited in terms of comprehensiveness and accuracy. Its usefulness may be limited to early design stage (project planning and route selection) activities or to projects with minimal planned excavations.

Quality Level C (QL C) involves surveying visible above-ground utility facilities, such as manholes, valve boxes, posts, etc., and correlating this information with existing utility records (i.e., QL D data). When using this information, it is not unusual to find underground utilities that have been either omitted or erroneously plotted. QL C information may not, however, eliminate all inaccuracies; nor will it reveal an unrecorded line that has no surface features. Therefore, its usefulness may be limited to preliminary design reviews or to projects with minimal anticipated conflicts.

Quality Level B (QL B) involves the use of surface geophysical techniques to determine the existence and horizontal position of underground utilities. This activity is called "designating". It further correlates utility records and surface topographical information, and may also help reveal unrecorded lines. Two-dimensional mapping information is obtained. This information may be sufficient to accomplish preliminary engineering goals, by helping the designer to determine where to place storm drainage systems, footers, foundations, and other design features in order to avoid conflicts with existing utilities. Slight adjustments in the design may produce substantial cost savings by eliminating utility relocations.

Quality Level A (QL A ) involves the use of nondestructive digging equipment at discrete, critical points to determine the precise horizontal and vertical position of underground utilities, as well as the type, size, condition, material, and other characteristics. This activity is called "locating." It is the highest quality level presently available. This information, when combined with other surveyed and mapped information, allows the designer to infer plan and profile information, for use in making final design decisions. By knowing exactly where a utility is positioned in three dimensions, the designer can accurately determine the extent of a utility conflict, or can often make small adjustments in elevations or horizontal locations and avoid the need to relocate utilities. Additional information such as utility material, condition, size, soil contamination, and paving thickness also assists the designer and utility owner in their decisions. QL A information (in the form of test hole logs), when included in the project bid documents, may yield more favorable bids due to reduced contractor uncertainty about subsurface conditions.

SUE Consultants

This list is not intended to be a list of pre-qualified SUE providers. This list is SUE providers that have a contract with CDOT.

No formal procedure has been established for CDOT personnel to follow in selecting one consultant versus other one for a particular project. In choosing which consultant to use, factors such as specific consultant capabilities, and the ability of the consultant to meet desired timeframes for commencing and completing the SUE work may be considered. It is not appropriate to contact multiple consultants with the intention of soliciting competing cost estimates.

SUE Task Order Procedures 

  1. The CDOT Region Utility Engineer (RUE), in coordination with (as appropriate) the CDOT project manager, resident engineer and region survey coordinator, must develop a project-specific Scope of Work and send it to the SUE consultant on CDOT letterhead. Examples for previous projects may be obtained either from other RUEs or the Headquarters Utilities Unit.

    Also, each of the two SUE NPS contracts that have been established includes the original Scope-of-Work for the NPS contract. The NPS Scope-of-Work can be used as a starting point for developing the project-specific Scope-of-Work. Copies of the NPS Scope-of-Work can be obtained either from the RUE, or the HQ Utilities Unit.
  2. The RUE, working with the project manager, must prepare a CDOT cost estimate for the work described in the project Scope of Work. Examples of previous project cost estimates are also available from the RUE or Headquarters Utilities Unit.
  3. The consultant must review the Scope of Work scope and prepare a Task Proposal with their own cost estimate. It may be necessary to negotiate work items and/or costs. Once agreement on the work and costs is reached, the consultant must submit three original signed copies of the Task Proposal.
  4. The RUE must obtain written approval of the Task Proposal from the regional transportation director (RTD); an email is sufficient.
  5. A CDOT standard Task Order Letter must be filled out to the extent possible (some items must be completed by the Headquarters Agreements Office later on), and the Region Business Office must generate a PG document. The standard Task Order Letter form may be obtained from the Region Business Office.
  6. The following items must then be sent to the CDOT HQ Agreements.Three copies of each of the following:
    • The original CDOT Scope of Work and cover letter that was sent to the consultant on CDOT letterhead
    • The CDOT RUE/Project Engineer cost estimate of the work
    • All three original signed copies of the consultant's Task Proposal
    • The partially completed Task Order Letter
    • The PG document
    • Unless an approval email has already been forwarded to Mike Como, written approval from the RTD
  7. The Headquarters Agreements Office will process the Task Order for all final approvals. Once such approval is obtained, the Agreements Office will coordinate issuance of the Notice to Proceed letter with the Region. The consultant may not proceed with any work until the NTP letter has been sent out.

    More information about SUE or use of the NPS consultant contracts may be obtained from the RUE or the HQ Utilities Unit.
