Several scheduling programs are available for the construction process. These include:

1. Microsoft Project (office.microsoft.com/en-us/project/default.aspx)

2. Primavera Project Planner (primavera.com)

3. Suretrak Project Manager by Primavera Systems ("Primavera Light") (primavera.com/products/suretrak.asp)

Scheduling programs cannot tell you how to sequence the activities of a project. Thus, the sequence established for, for example, concrete placement (see section immediately following) would have to be developed by a knowledgeable PM. The scheduling program will take the information provided by the PM and then graphically show the activities of their interaction with other relevant activities.

The scheduling program has other capabilities besides showing a graphic representation of the activities and the time associated with each one:

1. Resources (material/manpower) for the activity (Exhibit 15-6)

2. Cost related to the activity (Exhibit 15-7)

3. Baseline (initial) schedule (Exhibit 15-2)

4. Progress of the schedule and percentage complete of each activity (Exhibit 15-8)

A Concrete Pour

If we look at Exhibit 15-9, we see that the 75 ft X 75 ft concrete deck of a tenth-floor slab has to be poured. The activities noted in Exhibit 15-10 are required to construct the 75 ft X 75 ft floor area.

Exhibits 15-2 and 15-4 are the bar chart and CPM charts that depict the concrete pour.

When preparing a schedule, the checklist in Exhibit 15-11 should be reviewed.

Factors Affecting Schedules

The following factors affect schedules:

• Availability of labor

• Availability of material

• Weather conditions

• Proper winter protection

• Hunting season (especially in urban areas where the trades people have to travel long distances to hunting reserves)

• Restriction of activity mandated by a municipality (i.e., parades, VIPs coming to the city)

• Labor disputes

• Changes requested by the owner or architect

• Safety issues

• Insurance company evaluation of the site

• Municipal safety agency site inspections (including OSHA)

• Fires with damage

• Unforeseen site conditions

• Archeology finds
