The basic data used in preparing the plans can be found on the condition diagram and the design layout sketch submitted with the recommendations. These sheets plus additional information, such as the exact location of all utilities, should be available when preparing the detailed plans.

Affected Utilities.

Negotiations with affected utilities must be started upon approval to begin plans for a project so that any utility adjustments can be made promptly when work begins.

Survey Data and Photographs.

All survey data should be kept in a neat and detailed form so it can be referred to at any time. By detailing all information and obtaining photographs of the location and special features, unnecessary trips to the location may be eliminated. For this reason, adequate time should be devoted to project surveys and photographs.
