Preliminary Calculations Earthmoving Fleet Productivity and Project Time Estimation
Project Information
The project consists of excavating a rectangular site and hauling the material to a disposal area located 4 miles away.
Site Dimensions
Parameter Value Length 300 yd
Width 200 yd Excavation Depth 5 ft
Soil Type Common Earth Swell Factor 25%
Haul Distance 4 miles Haul Grade 4% upgrade
1. Total Excavation Quantity Bank Volume (BCY)
Excavation volume is calculated as:
V = L \times W \times D
Depth must be converted to yards:
5 ft = \frac{5}{3} = 1.667\ yd
V = 300 \times 200 \times 1.667
V = 100,020 \approx 100,000\ BCY
Loose Volume (LCY)
With a 25% swell factor:
LCY = BCY (1 + swell)
LCY = 100,000 (1.25)
LCY = 125,000\ LCY
Therefore, the trucks must haul:
125,000 LCY
2. Equipment Selection The following equipment was selected for the earthmoving operation.
Equipment Model Key Specifications Excavator CAT 336 Bucket capacity = 2.5 yd³ Dump Truck CAT 730 ADT Capacity = 20 LCY Dozer CAT D6 Used for site support and
grading
3. Excavator Productivity Excavator cycle time is assumed to be 25 seconds.
Cycles per Hour
3600 25 = 144 c𝑦𝑐𝑙𝑒𝑠/ℎr
Adjusting for job efficiency (0.83):
144 × 0.83 = 119.5 ≈ 120 c𝑦𝑐𝑙𝑒𝑠/ℎ𝑟
Excavator Production
𝑃𝑟𝑜𝑑𝑢𝑐𝑡𝑖𝑜𝑛 = 𝑐𝑦𝑐𝑙𝑒𝑠/ℎ𝑟 × 𝑏𝑢𝑐𝑘𝑒𝑡 c𝑎𝑝𝑎𝑐𝑖𝑡𝑦
𝑃𝑟𝑜𝑑𝑢𝑐𝑡𝑖𝑜𝑛 = 120 × 2.5
𝑃𝑟𝑜𝑑𝑢𝑐𝑡𝑖𝑜𝑛 = 300 𝐶𝑌/ℎ𝑟
Excavator productivity:
300 𝐿𝐶𝑌/ℎ𝑟
4. Truck Cycle Time Haul distance to disposal site = 4 miles
Assume average truck speed = 30 mph
Haul Time
4 30 = 0.133 ℎ𝑟
0.133 × 60 = 8 m𝑖𝑛𝑢𝑡𝑒𝑠
Return Time
Return travel time = 8 minutes
Additional Operation Times
Operation Time Loading 2 min Dumping 1min
Spotting / Maneuvering 1min
Total Cycle Time
CT = 2 + 8 + 1 + 8 + 1
CT = 20 minutes
5. Truck Productivity Formula
𝑄 = 𝑞 × 60 × 𝑁 × 𝐸
𝐶𝑇
Where:
Variable Description q truck capacity
N number of trucks
E job efficiency
CT cycle time
6. Fleet Productivity Calculations Fleet 1 – Primary Fleet Equipment:
• 1 CAT 336 Excavator • 4 CAT 730 Dump Trucks • 1 CAT D6 Dozer
Truck Production
𝑄 = 20 × 60 × 4 × 0.83
20
𝑄 = 199 𝐿𝐶𝑌/ℎ𝑟
Excavator capacity = 300 LCY/hr
Fleet productivity is limited by trucks.
Fleet Production = 199 LCY/hr
Project Time
𝑇 = 125000 199
T = 628\ hours
𝐷𝑎𝑦𝑠 = 628 8 = 78.5 days
Fleet 2 – Alternative Fleet 1 Equipment:
• 1 CAT 336 Excavator • 5 CAT 730 Dump Trucks • 1 CAT D6 Dozer
Truck Production
𝑄 = 20 × 60 × 5 × 0.83
20
𝑄 = 249 𝐿𝐶𝑌/ℎ𝑟
Excavator limit = 300 LCY/hr
Fleet Production = 249 LCY/hr
Project Time
𝑇 = 125000 249
T = 502 hours
𝐷𝑎𝑦𝑠 = 502 8 = 62.7 Days
Fleet 3 – Alternative Fleet 2 Equipment:
• 1 CAT 336 Excavator • 6 CAT 730 Dump Trucks • 1 CAT D6 Dozer
Truck Production
𝑄 = 20 × 60 × 6 × 0.83
20
Q = 299 LCY/hr
Excavator limit = 300 LCY/hr
Fleet Production = 299 LCY/hr
Project Time
𝑇 = 125000 299
T = 418 hours
𝐷𝑎𝑦𝑠 = 418 8 = 52.3 𝐷𝑎𝑦𝑠
7. Fleet Comparison Fleet Numbers of
Trucks Productivity (LCY/hr)
Total Hours Total Days
Primary Fleet 4 199 628 78.5 Alternative Fleet 1 5 249 502 62.7
Alternative Fleet 2 6 299 418 52.3
8. Conclusion Increasing the number of dump trucks improves hauling productivity and reduces project duration.
The Alternative Fleet 2 (6 trucks) provides the highest productivity and the shortest estimated completion time of approximately 52 days.

BCN 3727 CONSTRUCTION SITEWORK & EQUIPMENT
Term Project (200 Points)
Final Report and Presentation are
due on Friday, April 17, 2026 @ 11:59 p.m.
1. INTRODUCTION and PROJECT DESCRIPTION During construction work, it is necessary to conduct site preparation and excavation works
for the foundations of buildings. For this project, you are given the site preparation and excavation
works for the foundation of a large mixed used residential/commercial project close to downtown
Miami. The land is 300 yards long and 200 yards wide. The site is reasonably level terrain with
firm ground and approximately less than 25% rock content. The project specifications require
excavating 5 ft. of the entire land area. You have identified a disposal site 4 miles away from the
jobsite with a 4% slope upwards from the site to the disposal. Most of the soil at the site consists
of common earth with 25% swell. You can make reasonable assumptions wherever information
is not provided in this project description (e.g., about soil density and moisture content of the soil,
etc.). You need to clearly state your assumptions before making any calculations regarding the
earthmoving/earthwork operations.
2. INSTRUCTIONS You are required to define three equipment crew compositions (one primary fleet and two
alternatives) for this project. Crews may include combinations of dozers, excavators, hauling
trucks, loaders, support vehicles, etc. Complete the following:
1. Identify Equipment
• Research appropriate brands and models using the internet, operator’s manuals, and
other commercially available data.
• Use manufacturer performance characteristics (e.g., bucket capacity, engine power,
gross machine weight, productivity rates) as the basis for your analysis.
• Make reasonable assumptions where needed (e.g., soil density and moisture content).
2. Analyze Each Fleet
Using the data collected, determine:
a) Productivity of each fleet
b) Ownership and operating costs
c) Trade-offs between productivity and cost across fleets
d) Rent, lease, or buy options, with rationale for each option
3. Compare Alternatives
• Evaluate and compare the fleets based on their ability to perform the job, their
productivity, and by comparing rent/lease/buy options for each
• Estimate project time and cost for each
4. Select Optimum Fleet
• Present your final choice of the most effective fleet, supported by your analysis.

questions/concerns earlier rather than later. Lack of understanding of the requirements of the term
project does not entitle students to extra credits or extension of deadlines. Student groups should
schedule an appointment to meet with the instructor if any questions may arise.
