Construction Activities
On-site safety hazard and risk assessment
To accomplish a zero accident construction project. We have decided to build temporary fences around the site. This prevents pedestrians and other non workers from entering the construction site by accident. Second, we will perform Field Level Risk Assessments (FLRA) to ensure that hazards on the field can be avoided. Managers on the field will learn to observe, interact, and coach employees on safety. Another safety feature we are implementing is providing award winning safety courses for every new employee.We will highlight the importance of personal protective equipment (PPE) such as helmets, goggles, and gloves. There will be a bunch of lightings available during the nigh so working at the later hours can be done safely.
Earthwork Schedule
Shown to the right is our construction schedule. It shows the dates that each Job will finish. Each Job will be a predecessor for the next so they will go in order. Our construction starts on September 1st and ends on September 25th. September 13th is taken off.
Cost Estimation
Shown to the right is a cumulative cost estimation for our project plan. As you can see the cost slowly goes up as time on the project goes on.
This is to allow the contractor to see if their project is on budget as the project moves on to see if the project needs to have less or more money spent.
Earth Hauling Production on Each Job
This table will show the Jobs to be done along with the haul distances for those jobs respectively.
It will outline the cycle time for each job which depends heavily on the haul distance and the type of machine being used, and based on that cycle time as well as the crew working will outline the capable productivity for that specific job.
This is useful to determine the productivity for each job and was a central piece in determining our scheduling and cost during the project.
Crew
This Table shows the path that each job takes, along with the productivity which enables our team to find the cost per loose cubic meter. This was essential in determining the overall project cost and scheduling as well.
As you can see in row 1, one dozer/truck has a productivity of 3.85 lm^3/hr, with 24 trucks though the productivity jumps to 92.44 lm^3/hr. This allows us to get the $/lm^3 and that is very valuable information.
Sequence jobs and activity duration
The chart shown to the right shows the volume of earthworks moved in each job in both bank cubic meters as well as loose cubic meters using the swell factor given in the assignment.
The next column shows the crew productivity and how long each job would take.
This was an essential step in determining the overall project duration. This is valuable information to know so that the project can stay on schedule. Down a few sections from this one in the section 'Earthworks Schedule' shows a calendar with the scheduling. The duration of each job was taken into account in this table to the right to create that schedule in the lower section.
Cost
In the table to the right is the volume of earthworks moved for each job.
This table also shows the labour cost per bank cubic meter in the project in terms of crew (workers) as well as equipment. This allows us to find our entire labour cost and crew cost.
Project Overview
This Pie chart illustrates the significance of the costs towards the project and how much they contribute to the overall cost of the project. The total bid price of the project was $405,470.59. with a unit price of $45.89 per cubic bank meter
Cost Summary
Shown to the right is a summary of our projects indirect costs. This portion includes our indirect cost summary (engineering fees, permits, insurance, overheads/profits, surety bonds) which add to the cost of the project.
Along with the indirect costs is the total cost including direct costs.
