This work effort consisted of an initial "feeler" questionnaire survey of many State highway and local roads agencies, a more ~n-dep~ questionnaire survey of selected respondents to the first survey, and on-site interviews win some of Me more experienced and focused agencies. The first questionnaire survey was a 2-page mailing designed to determine The size of an agency's maintenance budget, the areas of maintenance included in the budget, and the existence of QA programs for each of the maintenance areas.

For cities and counties, Me range was 13 to 505, win an average of 121 employees. Although State and Provincial agencies were largely involved in pavement and bridge maintenance, mowing and landscaping, drainage, snow and ice removal, and traffic services, only a handful of cities and counties performed roadside maintenance, and a much higher percentage of these agencies indicated pavement resurfacing and pavement sweeping.

Of the 38 States and Provinces Mat completed We survey, 19 replied Mat they have no QA programs. The remaining agencies indicated Blat they currently have QA programs anyplace in some areas or are working on implementing ~em.

6/9 3/4 Agency has anyplace QC process to ensure accurate LOS ratings .

From page 43... ...
LOS ratings were found to be most applied to pavement maintenance activities, with eight of He nine agencies specifying this element. Five agencies listed bridges traffic services, roadside, and vegetation, and three agencies specified winter maintenance activities.

Field Reviews As previously discussed, in-depth field reviews and analysis of maintenance quality programs at seven agencies were conducted following He second project survey. The agencies were selected on He basis of how comprehensive and well defined Heir quality programs were reported as being and He extent to which long-term, end-result performance was emphasized In He assessment of quality.

Assessments are made using pass-fail ratings Mat Indicate conformance or nonconformance win established agencywide LOS criteria, which In turn is reflective of long-term, end-result performance. Table 6 illustrates Florida's maintenance rating standards for roadway characteristics.

By clefinition, no LOS rating system currently exists in this agency, although county, district, and central office staff meet annually to develop and modify criteria for Me LOS expected from daily crew operations. Like Maryland, Pennsylvania reported having a fairly effective CQl program.

Virginia Beach also rated Weir CQl program as fairly effective and asserted Mat it is an integral part of Me city's total quality program. Process unprovement teams, made up of employees from different levels of the organization, are formed to study various selected issues.

Lastly, with respect to CQI, Oregon rated Heir program as fairly effective and reasserted the use of self-managed teams to increase ownership In He final product. British Columbia Highway maintenance in He Province of British Columbia was completely pr~vatized In 1988.

The process requires certification document; and random selection and testing win periodic audits to ensure specification compliance. (Most agencies visited rely on a qualified products list, but have no formal QA program operated by maintenance personnel to monitor He quality of materials used.)
