John and Jane Doe Site Development andManufactured Home Installation Construction Project Management Course Project
Introduction• This project will convert the undeveloped private land parcel belonging to John and Jane Doe (the Owners) into a developed and landscaped parcel. It will include the installation and full set up of a new manufactured home.
Executive Summary• The Owners hold title to the 4.95 acre property in Santa Ysabel, California identified by APN 123-456-78.• They have entered into a contract with Acme Homes, Inc. to purchase a 2475 sq. ft. manufactured home which is to be installed on that property.• The expected delivery date is in July of 2012.• Currently the property has no improvements such as buildings, driveways or utilities.• The Owners have selected their preferred home site. Initial inspection indicates that it should be an acceptable location.• Water will be provided from a well source which needs to be located and installed. There is some risk that a good water source cannot be found, but adjacent parcels have reported no problems with their wells.• Household wastewater disposal will be via a septic system. This also presents some risk in that an acceptable location for a leach field may not be available. Or, the location may dictate that we move the home site.• Once the water and the wastewater disposal systems are approved, site development will continue with grading and bringing utilities to the site.• Next the foundation will be prepared including pouring a garage slab, a water system slab and the stem wall footing with properly installed rebar and hold-down straps.• Prior to actual installation of the home, landscaping of the property can be started, outside the home site.• Some improvements requested: small rock wall with lighted address, a gazebo, a small pond and fountain.• The owners have requested a 2.5 car garage (28 ft x 26 ft) added to the home.• Once the home installation and garage construction are substantially complete, landscaping of the home site can continue. The driveway surfacing can also be completed.
Customer AnalysisThe Owners, John and Jane Doe, will jointly own the finished project and have the sole responsibility for accepting the finished product as acceptable.• Their main concerns for the project are: – Work should be done with a high degree of quality – The final product should match the plans and specifications – The costs should not exceed the contracted amount – The project should be completed on schedule
Project Deliverables• Full installation of the Owners’ manufactured home with a Certificate of Occupancy from the County of San Diego.• Construction of the garage per plans and included in the Certificate of Occupancy• Installation of the road, driveway and parking area as specified in the plans• Complete landscaping of the property as specified in the plans
Objective Completion Criteria• The Certificate of Occupancy is issued• The design consultants agree that the project has been completed to meet their plans and specifications• Additional success criteria include: – Project completed within budget – Project completed on schedule • Completion Date is November 5, 2012

Project Overview Project ScopeThe scope of this Project includes:• developing the construction plans, the grading plans and the landscape plans• acquiring all required permits and approvals• installation of the water well and a water system including a pump, a 10,000 gallon storage tank and all required piping• installation of a properly designed and approved septic system• installation of an unpaved (except see 5 below) driveway between the access road and the garage with a parking area adequate for at least four average sized vehicles• the parking area, the 100 feet of driveway before the parking area and the driveway between the parking area and the garage will be concrete• all grading work to complete the driveway, the landscaping and the building of the foundation• bringing the electrical, telephone and, if available, the cable utility services to the home• building the foundation for the home• installation of the home on the foundation• finishing the exterior and exterior of the home• installation of a rock facing (type yet to be determined) on the foundation stem wall• installation of a 16’ by 32’ concrete patio at the family room doorway• installation of a 5’ by 8’ covered front porch with a concrete slab, concrete steps and stone facing on the porch foundation to match the home foundation• installation of a 2.5 car (28’ x 20’) garage on concrete slab• garage will be detached but closely adjacent with all separations acceptably hidden• garage will be design to match the architectural details of the home• garage will be insulated and the interior will be finished but it will not be heated or cooled except by fresh air ventilationThe project scope specifically does not include:• purchase of the manufactured home nor any involvement regarding that purchase.• delivery of the manufactured home to the home site. The Owners will contract with a carrier of their choosing to transport the home to the site and to position over the footing in a manner acceptable to the project manager.• repair of damage or deficiencies present on the home at the time of delivery.
Project Overview Project DependenciesThe successful completion of this project depends upon the following external processes:• The Manufactured Home Builder must complete construction of the home no later than the date to which they have agreed with the Owners• Transportation of the home to the work site must be completed successfully

Project Strategy• The overall approach to planning and executing the project will be to model the project plan after similar past successful project plans. All stakeholders will be kept informed as the plan is executed. .• The cross functional planning team will consist of the General Contractor, the Project Manager and the Owner. The cross functional planning process will depend on the Project Manager for the bulk of the planning with other team members advising and assisting as required.• The strategy to select the construction methods will be to depend on traditional manufactured home techniques. The design solution will be derived by a design team made up of an architectural consultant, a civil engineering consultant, a landscaping consultant and, if required, a structural engineering consultant.
