ENG106 Engineering Economics Project Winter 2012 Team Organization Begin by identifying other engineers to join your team for this project; your group will have 4-6 people. Send Dr. Holland an email (one per team, w/cc to all team members) by January 20 with the member’s names and team name (your choice). The team may delegate tasks to each person, however, everyone has ownership: all should understand what went into the analysis and agree that the analysis is correct. If the team finds an individual is not carrying his/her share, send me an email. Problem Description A twelve foot wide truck lane will be added to both sides of I-80 between Vacaville and Davis and will be 11 miles long. This section of roadway is located in Caltrans’ District 4. A life- cycle cost analysis will be made on various scenarios to determine whether it will be constructed of Jointed Plain Concrete Pavement (JPCP), Continously Reinforced Concrete Pavement (CRCP) or hot mix asphalt (HMA) pavement. The JCPC and CRCP designs will be 40 year design lives and the HMA design will be a 20 year design life. These pavement structures are shown in the structures handout, under the project folder on the (Smartsite, I80 Designs.pdf). The climate area for this section of highway is given in the file (Smartsite, Pavement_Climateregions_100505.pdf).

ENG106 Engineering Economics Project Winter 2012 The initial construction costs will be estimated using the Caltrans website for cost data and the structural data. The appropriate codes for the cost items are given in table 1. The URL for the cost data is at: http://www.dot.ca.gov/hq/esc/oe/awards/ Annual maintenance costs (given as CapM and Rehabilitation) for PCC and AC is described in section 2.5.2 and are given in Appendix A of the Life Cycle Cost Manual (Smartsite,
