Engineering Design of two lane road


Introduction:
The following will describe the Engineering Design process of a two lane road connecting Malibu Canyon road to a proposed recreational development with a parking facility.
(This project is an assignment give to students of CE-195 (Civil Engineering Design I) at Cal. State Los Angeles.)

The process starts with defining the Problem:
A new recreational area is being proposed at a location ....def.htm

The search for pertinent information:
Once I had a clear understanding of the project.  I had to start gathering pertinent information to the project ...data.htm

Generate Multiple Solutions:
You have already gathered all the information, specifications and requirements necessary to start your design.  It is important to provide your customer with multiple designs to give him the opportunity to choose the one he likes the most.  Each member of our group has chosen a route and will design it.  You will find the analysis for the route I chose in the following  section.

Analysis of Alternate Solution #3:
Route #3 has an average slope of about 8 % throughout the entire 4800 feet length of the road.  The slope where the road connects to Malibu Canyon road is not to sleep making the design process easier at the intersection.  s that The proposed road has only four curves which will make the road mostly straight and a lot safer then a curvy road. 

        Longitudinal Profile of proposed route #3..Longi.htm

        Road sections where drawn at every 300 feet.  The following are examples of road sections at different locations...sections.htm.

        These sections where also used to place retaining walls and to calculate the volume of soil to be cut and filled and required areas and lengths to estimate the cost...volcost.htm

        The Parking lot requires 50 parking spaces, 3 of them will be Handicap parking spaces to comply with ADA requirements.  Parking lot lay out ..parking.htm

Recommendation:
This route is recommended in the basis that it provides an average slope of about 8%.  It also has only three  measurable curves along its length therefore making it a safe road to travel on. Although the cost will be higher by the use of retaining walls it is well worth the expense because the natural landscape will be preserved.  This road will turn out to be a beautiful and safe road for people to travel on to the recreation area.
