Introduction

Coco Construction was tasked with planning a rough grading project for a high school campus in Guangzhou, China. Our company prides itself in our excellent commitment to customer service. We have over 20 years of skilled earthwork experience. Please browse our website to learn more about this exciting project.

Storyboard

We put together this interactive storyboard to assist with the visualization of our project progression.

Crews and Machine Utilization

Our teams for this project will be split into two crews. The first crew consists of a truck driver, dozer operator, and an excavator operator. The second crew consists of only a truck driver and excavator operator as only one dozer is required for the project.

Both trucks are used less in week 1 and more in week 2, as haul distances in week 1 are typically smaller and therefore do not require the use of trucks.

The dozer production rate is generally the limiting one, therefore is always in use for both weeks.

On certain jobs with less haul volume, only one excavator is required. This is typically the case in week 1. In week 2, haul volumes are larger and require both excavators more consistently.

On Site Safety Hazard and Risk Assessment

  • Coco Construction's priority is the safety of all involved in the construction process
  • Hazards and risks on a grading project include tripping hazards, moving equipment and potential injury from equipment and material handling
  • Fencing, high visibility signage, and floodlights for night work will help to alert people of hazards
  • PPE requirements will be enforced at the entrance to site

Cost Estimation

Project Cost Breakdown

Costs associated with this project are divided into two major categories: Indirect Costs and Direct Costs. Indirect Costs are further categorized into engineering, permits, insurance, overhead & profit, and surety bonds. Direct costs consist of equipment and labor costs.

The total cost for the management and execution of this project is $450,876. Refer to the chart below for a complete breakdown of the total cost into the relevant categories:

Cost Distribution

70% of project costs are direct costs, totaling at $314,411. Due to the nature of the job, high amounts of heavy machinery are required resulting in equipment costs making up 68% of direct costs, with the remaining costs contributing to labor. Project mobilization and demobilization costs are also included in both the labor and equipment portions of direct costs. The mobilization costs amounted to a total of $75,000.

Within the 30% of allotted indirect costs, engineering costs hold the largest portion at 18%. The remaining 12% is distrusted towards permits, insurance, overhead & profit, and surety bonds.

Potential Impacts

Minimizing the impacts of a busy construction site on the surrounding community is of utmost importance to CoCo Construction™. The following are the potential impacts of a busy construction site, and the solutions that we will be implementing to solve each relevant issue:

Noise:

  • Noisy equipment will be retrofitted with damping materials and/or mufflers to reduce sound.
  • Hours of operation for the majority of construction will be limited to regular work hours in order to prevent any disturbance during the night.

Safety:

  • Due to high fencing and protected site access points, students and residential community members will not be able to enter the site at any point.

School Access:

  • A stable, temporary walkway will be constructed to connect both the southern and northern campuses together. Students, parents, and faculty staff will be able to access the temporary walkway at all times of the day.

Traffic:

  • Phase 1 of our project will require use of public roads. In order to minimize disturbance, this will take place at night to reduce traffic congestion.
  • Community residents and small businesses will be provided in advance a detailed schedule of all traffic operations.

Environment:

  • Site access points will be constructed away from forest area to avoid deforestation.
  • Installation of a perimeter silt fence and several drain guards for surrounding catch basins will protect from contaminated storm water runoff.
  • We will use coarse gravel roads as an alternative to asphalt in order to minimize our carbon footprint.
