JOB SITE MANAGEMENT
GENERAL
NOTE
The information in this work package is provided as a supplement to the basic operating procedures
described in WP 0005 00 and the advanced operation and operating tips described in WP 0006 00. A thor-
ough reading and understanding of this work package and WP 0005 00 and WP 0006 00 is essential to safe
and efficient machine operation.
1.
This work package is designed to provide general job site information to maximize machine efficiency and potential as it
pertains to earthmoving operations.
2.
Proper job site management is crucial to work efficiency and is also included in this work package.
3.
When arriving at a job site the goal is to bring it to the desired grade. This is accomplished by cutting the high spots and
filling the low spots. The following general steps are performed:
a.
make it nominally flat using cut and fill operations to bring the site to the desired grade;
b.
perform land planing operations; and
c.
perform compaction operations.
4.
A typical work cycle at a job site consists of the following:
a.
cut;
b.
haul load;
c.
fill material; and
d.
return to fill site.
5.
The typical work cycle time is 6-12 minutes with generally 11 yards of material being moved per work cycle.
6.
Productivity is measured by the number of work cycles per hour. If the cycle time is less than 6 minutes, use of a dozer
may be considered. If the work cycle time is more than 12 minutes, a dump truck may be considered.
JOB SITE MANAGEMENT
Work Planning.
1.
a.
To ensure efficient completion of mission, work site should be surveyed in advance and a plan implemented so that
operators understand the requirements at each stage of the mission.
b.
During the work planning stage, a decision must be made on whether the machine needs to be adjusted to better per-
form its mission. Refer to WP 0006 00, Advanced Operation and Operator Tips.
c.
Operators should be kept informed of the work status to ensure the work is progressing according to plan and on
schedule.
d.
The key to a successful mission is good teamwork: planning, coordination, and communication.
Haul Road Construction and Maintenance.
2.
a.
Proper construction, operation, and maintenance of haul roads are essential to work efficiency. Building smooth haul
roads and keeping them free of ruts, washboards, and debris will enhance operator comfort and safety.
b.
Haul roads should be the width of three machines, typically 24 ft (7.3 m) minimum.
c.
Bank curves on haul roads. Avoid building a haul road that runs across a hillside; operation straight up and down hill
is recommended.
d.
Ensure grade on haul roads will provide good drainage.
