[Audio] Slide 1: Title Slide Mabry Car Wash Civil Site Development: Preliminary Cost Estimate & Construction Schedule Good morning, everyone. Our group project focused on developing a preliminary civil site cost estimate and construction schedule for the proposed Mabry Car Wash in Bedford County, Virginia. The purpose of this project was to review the civil plans, estimate the cost of the site development work, and create a realistic construction schedule. Our estimate only includes the civil site work and does not include the building construction. Throughout this presentation, I'll explain the project scope, how we developed our estimate, the major project costs, the construction schedule, and the risks we identified during the planning process.

[Audio] Slide 2: Project Overview This project is a new commercial car wash that will be constructed in Bedford County, Virginia. According to the plans, the building will be approximately 3,174 square feet and will disturb about 1.20 acres of land. Although the site is relatively small, it still requires a significant amount of civil work before the building can be constructed. Our estimate focuses on the site development only. That includes grading, utilities, storm drainage, erosion control, paving, concrete work, and final stabilization. Because this project was completed as an academic exercise, the estimate should be considered a planning-level estimate rather than a contractor's final bid. Page 3 of 14.

[Audio] Slide 3: Project Scope & Site Evaluation The existing property is mostly vacant with existing vegetation, nearby drainage infrastructure, roadway access, and public water service available. The grading plans show that runoff from the site will be directed toward a proposed storm drainage system and detention basin. Our scope of work begins with mobilization and survey before moving into erosion and sediment control. From there, the contractor would complete clearing, earthwork, storm drainage, water service installation, curb and gutter, asphalt paving, pavement markings, and final stabilization. The project also has several important construction considerations. Utility locations must be verified before excavation begins, erosion control measures must be installed before major grading, and work near the roadway will require careful traffic control and coordination.

[Audio] Slide 4: Estimating Methodology To develop the estimate, we followed a structured five-step process. First, we reviewed all of the civil drawings and specifications to identify every work item included within the site development. Next, we organized the project into a Work Breakdown Structure, which grouped similar construction activities together. After that, we completed quantity takeoffs using plan dimensions, schedules, and scaled measurements from the drawings. We then applied unit prices using several reliable sources, including VDOT estimating guidance, Virginia public bid tabulations, Bureau of Labor Statistics wage data, and engineering judgment. Finally, we added contingency, overhead, and contractor profit to produce a planning-level estimate. Several assumptions were also made, including normal weather conditions, no major rock excavation, and no significant utility conflicts during construction. Page 5 of 14.

[Audio] Slide 5: Work Breakdown Structure The Work Breakdown Structure helped organize the project into major construction phases. These included general conditions, erosion and sediment control, earthwork, storm drainage, water service, concrete work, pavement construction, and final stabilization. Breaking the project into these work packages made the estimate easier to prepare and also simplified the construction schedule. Each package could be estimated independently while still fitting into the overall project sequence. Page 6 of 14.

[Audio] Slide 6: Quantity Takeoffs & Cost Analysis After completing the quantity takeoffs, we developed a preliminary cost estimate. Some of the major quantities included approximately 2,500 square yards of asphalt pavement, 600 linear feet of curb and gutter, 750 linear feet of silt fence, and about 2,000 cubic yards of earthwork. The direct construction subtotal was approximately $521,640. We then added a 10 percent contingency to account for unknown conditions and quantity uncertainty. Finally, contractor overhead and profit were included, resulting in a total estimated project cost of approximately $659,875 when site lighting is included. If site lighting is treated as a separate electrical contract, the estimated cost decreases to approximately $521,990. Page 7 of 14.

[Audio] Slide 7: Major Cost Drivers Several work items contribute the most to the overall project cost. The largest cost driver is asphalt pavement because of the material quantities, hauling, paving equipment, and labor required. Storm drainage is another significant expense because it includes pipe installation, drainage structures, outlet protection, and detention basin construction. Earthwork also represents a major portion of the estimate because of grading, excavation, and compaction activities. Concrete curb and gutter require both skilled labor and specialized equipment, while site lighting becomes a major expense if it remains within the civil contract. Since this is a relatively small commercial project, mobilization costs also represent a larger percentage of the overall estimate compared to larger highway projects. Page 8 of 14.

[Audio] Slide 8: Construction Schedule Part 1 The construction schedule follows the normal sequence used for most civil site development projects. Construction begins with permits, mobilization, survey, and erosion control installation. Next comes clearing and earthwork, followed by storm drainage and water service installation. Once the utilities are complete, the contractor prepares the subgrade, installs curb and gutter, places the aggregate base, and completes asphalt paving. The project finishes with pavement striping, final stabilization, inspections, and project closeout. Page 9 of 14.

[Audio] Slide 9: Construction Schedule Part 2 This Gantt chart shows our preliminary construction schedule for the civil site work. The project begins with preconstruction activities, mobilization, and erosion and sediment control during the first two weeks. Once the site is prepared, clearing and rough grading begin, followed by storm drainage installation and the water service. After the utilities are completed, the contractor prepares the subgrade and installs the curb, concrete, and lighting foundations. The final phases include placing the aggregate base, asphalt paving, striping, and final site stabilization. Closeout activities are completed before a one-week weather allowance at the end of the schedule. Overall, the project is expected to take about 12 weeks, with several activities overlapping to improve efficiency and keep the project on schedule. The total construction duration is estimated to be about 56 working days. After adding a 10 percent weather allowance, the expected schedule is approximately 62 working days, or about 12 to 13 calendar weeks. Page 10 of 14.

[Audio] Slide 10: Risk Management & Recommendations Every construction project involves some level of risk. Some of the biggest risks for this project include unknown utility conflicts, weather delays, permit and inspection delays, unsuitable soil conditions, and changes in material prices. Because grading and paving operations depend heavily on weather, delays could affect both the schedule and project cost. To help reduce these risks, our estimate includes a 10 percent contingency, and the schedule includes additional weather time. Before construction begins, we also recommend verifying all utility locations, confirming quantity takeoffs, obtaining updated supplier pricing, and deciding whether site lighting should remain within the civil contract or be bid separately.

[Audio] Slide 11: Team Responsibilities Our project was completed as a team effort, with each member contributing to a different portion of the estimate. Responsibilities included reviewing the plans, performing quantity takeoffs, researching unit prices, preparing the construction schedule, writing the report, and developing the presentation. Dividing the work allowed us to complete the project more efficiently while ensuring that each section received adequate review. Page 12 of 14.

[Audio] Slide 12: Conclusion In conclusion, our team successfully developed a preliminary civil site cost estimate and construction schedule for the Mabry Car Wash project. Based on our analysis, the estimated project cost ranges from approximately $521,990 without site lighting to about $659,875 with lighting included. The estimated construction duration is approximately 12 to 13 weeks, including a weather allowance. Although this estimate is intended for planning purposes, it demonstrates the overall process used by civil engineers and contractors to prepare estimates and schedules before construction begins. Future work should include verifying all quantity takeoffs, obtaining updated supplier quotations, and confirming the final project scope before bidding. Page 13 of 14.
