SECTION 01320
CONSTRUCTION PROGRESS DOCUMENTATION
PART 1 - GENERAL
1.1 SUMMARY
A. This
Section includes administrative and procedural requirements for documenting the
progress of construction during performance of the Work, including the following:
1. Contractor's
Construction Schedule.
2. Submittals
Schedule.
3. Daily
construction reports.
4. Field
condition reports.
B. See
Division 1 Section "Summary of Multiple
Contracts" for preparing
a combined Contractor's
Construction Schedule.
C. See

1.2 DEFINITIONS
A. Activity:
A discrete part of a project that can be
identified for planning, scheduling, monitoring, and controlling the construction
project. Activities included in a construction
schedule consume time and resources.
1. Critical
activities are activities on the critical path.
They must start and finish on the
planned early start and finish times.
2. Predecessor
Activity: An activity that precedes another activity in the network.
3. Successor
Activity: An activity that follows another activity in the network.
B. CPM:
Critical path method, which is a method of
planning and scheduling a construction project where activities are arranged based
on activity relationships. Network calculations
determine when activities can be performed and the critical path of Project.
C. Critical
Path: The longest connected chain of interdependent
activities through the network schedule that establishes the minimum overall Project
duration and contains no float.
D. Float:
The measure of leeway in starting and completing an activity.
1. Float
time is not for the exclusive use or benefit of either Owner or Contractor, but
is a jointly owned, expiring Project resource available to both parties as needed
to meet schedule milestones and Contract completion date.
E. Fragnet:
A partial or fragmentary network that breaks
down activities into smaller activities for greater detail.
F. Major
Area: A story of construction, a separate building, or a similar significant construction
element.
