6 (How can you build on this minuscule site?)

LOGISTICS

Imagine a piece of vacant land that is surrounded on three sides by tall office buildings
and a busy street located on the fourth side. Now, you, as the Construction
Manager/General Contractor (CM/GC), have the responsibility of constructing a 60-story
office building on the site. Due to the constraints of the site, the CM/GC must develop a
plan that will achieve the objectives of getting material and labor to the site without affect-
ing the surrounding neighbors, the pedestrians, and the local street traffic. In addition, the
safety of the public and the trades people working at the site must be of paramount impor-
tance. The plan that will address these issues is called a logistic plan. Exhibit 6-1 is a
logistics flowchart.
Exhibit 6-2 is an example of an access plan for the construction of a major office build-
ing in an urban setting. Exhibit 6-3 shows the location of hoist/elevator/loading dock
for an urban project. Exhibit 6-4 is a plan showing the crane location on an urban site.
Exhibits 6-2, 6-3, and 6-4 constitute a logistics plan. Exhibit 6-5 is a list of items that
should be considered when preparing a logistics plan.

CRANES

Depending upon the height of the building constructed, a determination will have to be
made on the type of crane that should be used for this particular project. For heights of
up to 200 feet, a mobile crane can be utilized. Once this height is exceeded, then a
climber tower crane will have to be considered.
