This report traces the development of and explains the operation of a Construction Manpower Management System (CMMS) developed for the Virginia Department of Transportation (VDOT). Initial direction for this project was received from the Construction Engineering Manpower Management System Pooled Fund Study and a study performed for VDOT by Price Waterhouse and Roy Jorgensen Associates, Inc. Technical input was received from a project steering committee consisting of VDOT engineers, inspectors, and administrators. This system has been tailored to the specific needs of VDOT and provides projections of construction inspection staffing needs for both the short-term (the next 18 to 24 months) and the long-term (the next 6 years). The short-term projections are very accurate and appear quite adequate for use as a manpower staffing tool and for VDOT presentations to the General Assembly. As anticipated, the long-term projections, which are based on less certain project schedules in years 4 to 6, are not as accurate as those in the short-term. Thus, little use of long-term estimates are anticipated for planning purposes at this time.

This study attempted to establish and analyze relationships between forms of deterioration or distress that reduce the level of service provided by a highway pavement and the cost of correcting them. Using statistical computer analyses of 30 highway projects, the most significant relationships were identified. Very strong statistical relationships were identified between axle loadings (ESAL-18's) sustained and maintenance costs and between pavement age and maintenance costs. For a large majority of the projects, it was found that the unaccounted for variables (principally environmental) had no significant influence on the relationship between ESAL-18's and maintenance costs. With additional refinement, the results of this study could be used to predict needed levels of funding for highway maintenance activities.
