CLIENT: BERRYMAN & HENIGAR

The City of Cypress, CA, population 49,000, is about 30 miles south of Los Angeles. According to Cypress Assistant City Engineer Kamran Dadbeh, the City retained Berryman & Henigar to complete an arterial and collector pavement inventory and condition assessment that would comply with Orange County, CA 'Measure M' standards.
Measure M requires each city in the County to complete an arterial and collector pavement condition survey and report that indicates how the pavement network is performing. A standard pavement condition index (PCI) has been adopted by the Orange County Transportation Authority (OCTA) that defines a failed pavement section as a "0" PCI; a new street or reconstruction is shown as a "100" PCI. The project comprised assessing and updating the city's Pavement Management System (PMS) and converting data into a newer PMS software system - CartéGraph's PAVEMENTview Plus.
By building on the success of the first project, the firm recently completed a residential condition survey and conducted a condition assessment of all residential sidewalks, curbs and gutters. A principal task was collecting the standard pavement condition data for 94 centerline miles of residential streets and more than 200 miles of residential right-of-way (ROW) data and deficiencies (sidewalk/curb & gutter).
Dadbeh said the City Council placed a high priority on completing and implementing the results/recommendations of the residential condition survey because a citywide citizens' satisfaction survey indicated this issue was of paramount concern to residents.
A five-person Berryman & Henigar field crew used an innovative approach in collecting the requisite data, utilizing personal digital assistants (Pocket PC) -- Compaq Ipaq's with Windows Visual CE database functionality. In-house staff developed pavement condition survey forms on the Ipaq's to eliminate having to collect pavement data on paper or laptops. By using this methodology, a cost savings of approximately $5,000 or 15 percent of the project total was realized. This is a result of eliminating data entry from the process where instead, each field technician downloads his/her data into the CartéGraph PAVEMENTview Plus software on a daily basis.
Using the Pocket PC has resulted in a number of tangible benefits and advantages for Cypress:
With the Ipaq essentially acting as a mobile office for each project technician, communications and the costs savings previously mentioned are helping Berryman & Henigar improve the City's in-house technologies, e.g., linking project data to GIS software for Ipaq's such as Arc PAD from ESRI and wireless communications.
Cypress now has a sophisticated PMS in place that also meets current GASB-34 requirements, fast-tracked by using the Ipaq's. Dadbeh said if funding is available, the City may consider purchasing handhelds in the near future so they can immediately view key infrastructure information gleaned from the data compiled by Berryman & Henigar. The condition survey findings along with corresponding recommendations for implementing a cost-effective maintenance program now provide the City with information on:
