Question

1. The Dias project site is located at 42232 Mission Boulevard near the Interstate 680 in Fremont, California. Twenty homes were constructed on the hillside property, per the approved general land plan designation of Low-Density Residential. Upon completion of site preparation and grading, the installation of the right of ways and utilities and the construction of the residences was completed over approximately an 18-month period. The Dias project was approved by the City of Fremont in 2012; however, due to the economic downturn, the project did not gain momentum until early 2015. Robson Homes picked up the design and moved forward with the civil, landscape, architect, and joint trench designs. In developing the grading and improvement plans for the future homes, five agencies were involved in the submittal reviews. Agencies included and the respective jurisdictions are as follows:
   • Caltrans – Mission Boulevard right of way (Route 238)
   • Alameda County Water District – public water main connection & service laterals
   • Union Sanitary District – public sanitary sewer main connection & service laterals
   • City of Fremont: Building & Engineering Departments– public right of way and homes
   • PG&E – existing utility easement (two gas lines with a 50’ easement)

Construction on the site was initiated in February 2016. The Dias project gained approval from all five agencies in April 2016. However, unforeseen circumstances necessitated further changes to the engineering design. Despite this setback, the developer decided to move forward with the construction, accepting the risk of agency comments regarding the new engineering design. The constructed homes feature multi-car garages or detached garages with an upstairs studio. Homes are be two-story and have a minimum of four bedrooms and 3.5 baths. Because homes are located on a hillside, extensive grading studies for retaining walls are required. Lots have customized landscaping per Robson’s request and feature multiple trees along the new right of way and in each lot.

For this specific project, perform the following exercise:

• Identify and describe at least four project risks
• Estimate the likelihood of occurrence of the identified risk and rank the risk types by the least likely to most likely to occur.
• For the four identified risk, determine the risk significance (insignificant, minor, moderate, major)
• For the four identified risks, determine proposed mitigation efforts.

Answer 1

a)four project risks are

• economic downturn
• unforseen circumstances
• agency comments for new engineering design
• hillside construction especially retaining walls

b)ranking as per least likelihood to occur is unforseen circumstances

most likely occur retaining of walls

unforseem circumstances<agency comments<economic downturn<retaining of walls

c)risk is

unforseen circumstances= insignificant

agency comments =moderate

economic downturn=minor

retaining of walls=major

d)to mitigate the risk grading study is must

checking out of consequences and result if previous project, taking reviews from other companies

and also with proper plantation and scaling of land project can be successful
