Earthworks of Engineering Faculty
Parking Area
Presented by: 4th group
Introductions
Nowadays, Parking Area has become one of infrastructures needed along increasingly of vehicles volume especially at Engineering Faculty. Problems arising from the provision of parking space itself is vacant land needed. Vacant land located in the north of 4th Building requires an efficient construction methods that can be implemented practically

Identification
Identification
The following are main working items:
• Land clearing and top soil strippingThe purpose is for clearing the area from organics, therefore it will ready for next work.
• Soil heap workThis work is done by collecting soil from the excavation to be made as a pile of soil on the surface of the ground that has lower elevation than planned.
Identification
• Total Volume = Area x Depth
= 610,13 x 1,65
= 1006,715 m3
• Stripping Volume = Area x Stripping Depth
= 610,13 x 0,15
= 91,5195 m3
• Digging Volume = Total Volume – Stripping Volume
= 1006,715 – 91,5195
= 915,195 m3
Working Method Selection
Working Method
• Land clearing and top soil strippingUsing the excavator as the primary heavy equipment which is used for stripping and digging. The main idea is to use heavy equipment as little as possible, but efficient.
• Soil heap workLM that are transported by trucks to hauling site will condense by the compactor. The results are expected not to exceed a schedule of excavator.

Excavator
Productivity of Backhoe Komatsu PC60-1
• Cycle time (T) = 0,4 • Bucket Capacity (BC) Stripping = 0,25• Bucket Capacity (BC) Digging = 0,28 • Siteplan Management Condition= 0,75 (clay)• Bucket Factor (BF) Stripping = 0,5 • Bucket Factor (BF) Digging = 0,8
• Productivity of Stripping60/T×BC×JM×BF = 60/0,4×0,25×0,75×0,5 = 14 m3/hour
• Productivity of Digging60/T×BC×JM×BF = 60/0,4×0,28×0,75×0,8 = 25,2 m3/hour
Truck
Truck Productivity
• Distance = 500 m• Average Speed = 20 km/hour• Capacity = 5 m3
• Cycle Time• Loading = 11,9 minutes• Single Trip Time = 3 minutes• Position Setting = 5 minutes +
19,9 minutes
Amount trip/hour = 60/15,9
= 3,01 ≈ 3 trip
Compactor
Productivity of Compactor Vibro 10 ton
• Effective Width of Wheel (L) = 80 cm• Compactor Speed (V) = 2 km/hour • Total Tracks of Compacting (N) = 10• Layer Heights = 20 cm• Productivity
F= (L×V×JM)/N=(0,8×2000×0,75)/10= 120 m2/layer/hourCompactor Productivity = 0,2×120 = 24 m2/hour
