APPENDIX A TO SECTION 01300

Definitions

A. Baseline Construction Schedule: The CONTRACTOR’s as bid Work plan for the Contract, prepared using the Critical Path Method, which shows all planned activities, costs, resources and durations, as accepted to by the ENGINEER.

B. Cash Flow: The CONTRACTOR’s estimate of time-phased construction gross billings, before retention, generated from its scheduled cost-loaded activities.

C. Construction Schedule: The CONTRACTOR’s accepted Baseline Construction Schedule, as it evolves through periodic updates that record actual progress of the Work to completion when it shall show the “As-Built” record of the CONTRACTOR’s Work plan as executed.

D. Contemporaneous Period Analysis: A methodology, used in conjunction with a CPM schedule, to model the effects of a time impact event in near real time for a ‘forward- looking’ estimate of contract completion. Also referred to as Time Impact Analysis by the AACE.

E. Contract Completion: The final completion milestone date established by adding the duration in calendar days stipulated in the Contract agreement to the Notice to Proceed date, and as amended via change orders.

_{F. Contract Duration: The performance period provided for in the contract.}

G. Contract Milestone: Significant performance points in the Work, as provided for in the Contract

H. Cost-Loaded Schedule: The CONTRACTOR’s allocation of bid estimate costs to each schedule activity which forms the basis for anticipated CONTRACTOR gross billings before retention is withheld.

I. Critical Path: A continuous sequence of schedule network activities with the least amount of total float ending at a Contract Milestone.

J. Critical Path Method (CPM): Schedule development that starts with a proper plan sequenced from beginning to end, followed by time driven forward and backward passes to establish the Critical Path and the Float for all other paths.

K. Early Finish: The earliest a schedule activity is expected to finish, based on its relationship (logic) to other activities in the contract.

L. Early Start: The earliest a schedule activity is expected to start, based on its relationship (logic) to other activities in the contract.

M. Float: The flexibility that an activity has against the critical path

N. Fragnet: A fragment of the schedule network that typically illustrates a particular sequence for thorough analysis.

O. Free Float: The amount of time the start of an activity can be delayed without delaying the start of a successor activity.

P. Independent Float: The amount of time that an activity may be delayed without affecting the early start or early finish of any succeeding activities.

Q. Interim Construction Schedule: The CONTRACTOR’s as bid Work plan for that portion of the Contract that precedes adoption of the Baseline Construction Schedule prepared using the Critical Path Method and showing in detail all planned activities, logic, sequencing, costs, resources and durations planned for the interim period cited in this Specification section. It shall also include cost and resource loading to a summary level for the balance of all Contract Work through the Final Completion milestone as forecast by the CONTRACTOR.

R. Late Finish: the latest a schedule activity can finish, based on its relationship (logic)

to other activities on the contract, and still permit the contract to be completed on time.

S. Late Start: The latest a schedule activity can start, based on its relationship (logic) to other activities on the contract, and still permit the contract to be completed on time.

T. Longest Critical Path: A continuous sequence of schedule network activities that begins with the notice to proceed milestone and ends at the contract completion milestone.

U. Milestone: A significant schedule event identified in the Contract as a “milestone”.

V. Narrative Progress Report: A written report that summarizes the status of the Contract and narrates in detail progress of the Work during the report period, anticipated for the next reporting period and the outlook for completion of the Contract

W. Near-Critical Float: Is typically defined as float values within a set range just above the critical path float.

X. Original Duration: The amount of time, in calendar days, an activity is expected to take to complete at the beginning of a contract.

Y. Planned Completion: The construction completion milestone date established by the agreed to baseline construction schedule.

Z. Pre-Construction Scheduling Conference: The first meeting between the ENGINEER and the CONTRACTOR to review the requirements of this and related Specification sections, the CONTRACTOR’s proposed methodologies for its work breakdown structure, activity coding, identification, sequencing, cost, resource and quantity loading.

AA. Predicted Completion: A variable date predicted for completion of the Work in each periodic progress update.

BB. Primavera^® Project Management, latest version: The latest version of Primavera^®

_{scheduling software currently in use by OCSD.}

CC. Progress Period: The 28 day progress payment period established by the

ENGINEER for the contract.

DD. Project Float: The amount of time between the CONTRACTOR’s planned early completion date and the contract completion date.

EE. Recovery Schedule: The CONTRACTOR’s plan to mitigate its predicted delay to the

Contract completion date and conclude the Work as Contracted.

FF. Resource-loaded Schedule: The CONTRACTOR’s allocation of all labor and equipment necessary to complete the Work for each activity as entered into the schedule software database.

GG. Total Float: The amount of time that the actual start and finish of an activity can be delayed along a given network path without delaying the contract completion date

HH. Work Activity: An activity that requires time and resources to complete and must be performed before the Contract is considered complete.
