Weekly Schedule
Weekly Schedule
- Week 0
- In the initial week, there will be some preparation work during this week before actual earth moving work starts.
- Attention sign setup, information board, and site cleaning are scheduled to be finished before equipment and labor arrival.
- Parking area for trucks, dozers, and excavators will be prepared for the following earth work.
- Week 1
- The main focus for the first week is to dump extra material that won’t be used in further filling stage.
- Because 1st September is Sunday, the official earth work starts from 2nd September from 8 AM.
- Working site for the first week will be from Node 1 to Node 4.
- One excavator is used to conduct cutting work; because the distance from the working site to waste dumping location is pretty far, 4 to 5 dump trucks are prepared to transport the extra earth to waste site with the excavator working at the same time.
- Week 2
- For the second week, all crew will still work on dumping the earth that is not considered to be utilized in following earthmoving work package.
- All crews will take a break on 13 September due to Mid Autumn Festival.
- Before 13 September, Node 4 to Node 17 is the main construction site.
- In the second week, the traffic flow will be the same as the previous week, since most work in this week is still the earth dumping work.
- Week 3
- Before starting earth piling and filling work, the rest dumping work will be done first on 16th September.
- Node 15 and 16 are selected as piling locations for further earth filling work.
- Starting from 17th September, 2 excavators and 4 dozers are assigned for earth piling.
- The path for piling work will be simpler than the former work, cause our team will focus on 2 piling locations (node 15 and 16).
- Week 4
- In the fourth week, all the earth piling work is scheduled to be done before 25th September.
- Due to the distance for filling work is larger than the previous work, dump truck is chosen in this stage instead of dozers to reach higher economic efficiency.
- At the same time, these dump trucks can perform the rest dumping work for Node 47 and 51.
- Week 5
- National Holiday (no work from 1st October to 7th October)
- Week 6-7
- In last week, the rest filling work will be finished on 14th October.
- It will take 3 days to transport the remaining extra filling material piled on Node 15.
- The estimated finish date for this earthmoving project is on 16th October.
Cost estimation
Cost estimation
Direct cost overview
- Direct cost
Equipment usage and labor cost are the two main parts in direct cost analysis.
Additionally, insurance and benefit for labor cost analysis are already included. as shown in table.
Indirect cost overview
Indirect cost
Indirect cost
- Engineering Fees: in order to keep all machines on site safe and functioning well as scheduled, mechanical engineering fee need to be considered. Referring current labor market, $65/hr is used to calculated engineering fee, included insurance and benefit. The total cost for mechanical engineering fee comes down to $14,560
- Permits: based on previous local construction experience, the estimation for daily permit is $1500, which leads to the total price of $40,500
- Insurance: the estimation towards insurance cost is $26335.41 made by consulting different local insurance companies.
- Overhead and Profit: compared to current market price, the overhead and profit is set as $60,000 in total
- Surety bonds: by referring to Surety Association of Canada, performance bond can ensure up to the amount of 95% of the contract amount. By comparing with different local companies, the final price for surety bond comes to $50,000
Crew and machine utilization
Crew and machine utilization
- One excavator and 15 dump trucks will be utilized in stage 1 to maximize the crew productivity, since the distance between working site and waste site is 30 km. By assigning more dump trucks working on site, reducing the waiting time for excavator is the most efficient way to help operators perform their work.
- Two excavator and two to four dozers are assigned to conduct piling and filling work in stage 2 and 3. Because the rest nodes that needed to be filled are far from the start point, dump truck will still be used in few nodes, like node 35.
- As for the last stage, the crew and machine utilization will be the same as the first stage
- The working hour for this project is 8 hours each day, starting from 8 AM to 5 PM, and there will be 1 hour lunch break per day.

On-site safety hazard
On-site safety hazard
- Week 0
- Teachers, students, and residents nearby will be informed in advance in this week.
- Pre-meeting between main engineering crew is held to discuss risk and safety management.
- Week 1
- During the transportation of dumping the waste material, most concerned problem will be the traffic flow around the construction site. Because there are already 2 existing roads surrounded, it requires more attentions to maintain the safety of construction work. Signs and fences have built to ensure that it reminds passengers of the risks of construction activities
- The potential hazards during the first week might contain material and manual handling, objects moving, and air pollution. In order to reduce the possibilities of risks on site, personal protection equipment (PPE) and safety training will be provided on site, and there will be mechanical technician monitoring.
- Week 2
- In the second week, the traffic flow will be the same as the previous week, since most work in this week is still the earth dumping work.
- As for the risk management, the chance of on-site hazards are much more less than the first week since most crew have been done the safety training and more proficient with their work.
- Week 3
- Due to new task assigned to current crew team, more safety training and meeting are provided before daily work starts. There might be air pollution and noise problems involved in this week; therefore, more protecting and monitoring equipments are put in use. Safety always comes first in our company value.
- Week 4
- The traffic path goes longer in this stage, due to increasing distance between piling nodes and the working nodes. Dump trucks will be utilized this week to increase the efficiency of earth moving work.
- In the fourth week, daily safety meeting will still be conducted as before to ensure the safety of working site.
- Week 5
- National Holiday (no work from 1st October to 7th October)
- Week 6-7
- In the last two weeks, the path for transportation is the same as previous weeks for dump truck operators, after filling work is done.
- The main risks focus on cleaning up work. More protection equipment and training will be provided. It is our priority to minimize the potential impact to other stakeholders.

- Social responsibilities
As a local base company, A$AP is devoted to participate and get more involved for bonding our community. A$AP will require the work site to be strategically placed so that it does not intersect with pedestrian walkway and residential traffic as much as possible. A$AP will ensure proper fencing and signage for traffic rerouting. Adequate training and signage to be placed to ensure safety of all personals and visitors on site. Visitors will be required to sign in and sign out of a log book and have proper PPE.
2. Company safety culture
All company employees are to be provided with required safety training as a part of orientation. A$AP's goal is to maintain a safe and healthy environment by correcting situations that caused or could likely cause injury. When an incident occurs, it is important to report the occurrence so actions such as an investigation can be taken to make sure that a similar or more serious incident does not happen again.
3. Local site investigation
Before any work is completed on site, an initial site safety evaluation is required to establish safe working conditions and to eliminate any potential safety hazards. All utility lines like drainage, power, gas lines and electrical lines are to be marked as a part of initial site hazard assessment. Site access to be marked with proper signage and kept clean of any garbage at all times. All surrounding areas within the excavators swing are to be kept clear and clean for better safety of all personnel on site.
4. Safety training and meeting
Daily toolbox meetings are to take place every day before any work is to begin. Toolbox meetings are to discuss necessary risks and hazards that could potentially arise on that day. Additionally, employees in charge of operating heavy equipment( ex. excavators and haul trucks) are required to complete a daily equipment inspection form before the shift and after. Trucks or machinery will not to be operated at any time if it deemed unsafe by the daily equipment inspection. The daily equipment inspection forms from the previous days shift are to be handed in at the next mornings daily toolbox talk to allow any equipment to be removed from service for repair and to verify all equipment is in working order. Airborne contaminants are a potential hazard to the crew. All crew are required to be mask fit tested to ensure their better safety.
