CONSTRUCTION PROGRESS DOCUMENTATION

PART 1 GENERAL

1.1 DEFINITIONS

A. Critical Path Method – Critical path method (CPM) shall be interpreted to be generally as outlined in the Association of General Contractors (AGC) publication. “The Use of CPM in Construction.” except that either “i-j” arrow diagrams or precedence diagramming format may be utilized.

B. Construction Schedules – Construction schedules shall include a bar chart, graphic network diagrams, and computerized construction schedule reports.

C. CPM Network – CPM network shall be in a form of a time scaled “i-j” activity-on-arrow or precedence type diagram and may be divided into a number of separate sheets with suitable match lines relating the interface points among the sheets. Individual sheets shall not exceed 22- by 34-inch.

D. Duration Estimates – The duration estimate indicated for each activity shall be computed in days and shall represent the single best estimate considering the scope of the activity work and resources planned for the activity. Except for certain non-labor activities such as curing of concrete or delivery of materials, activity duration shall not exceed 30 days nor less than one day unless otherwise accepted by CONTRACTING OFFICER or

CONTRACTING OFFICER’S REPRESENTATIVE.

E. Float – Unless otherwise provided herein, float as referenced in these documents is total float. Total float is a period of time measured by the number of days each non-critical path activity may be delayed before it and its succeeding activities become part of the critical path. If a non-critical path activity is delayed beyond its float period, that activity then becomes part of the critical path and controls the end date of the project.

F. Float Ownership – Neither CONTRACTING OFFICER nor CONTRACTOR owns the float time. The project owns the float time. As such, liability for delay of the project completion date rests with the party actually causing delay to the project completion date. For example, if Party A uses some, but not all, of the float time and Party B later uses the remainder of the float time as well as additional time beyond the float time, Party B shall be liable for the costs associated with the time that represents delay to the project’s completion date. Party A would not be responsible for any costs since it did not consume all of the float time and additional float time remained; therefore, the project’s completion date was unaffected.

D. Changes or delays that do not affect the controlling operator or operations of the critical path will not be considered as a basis for a time adjustment. Changes or delays that do not affect the controlling operations or the critical path will be considered in granting an extension of time for completion of the contract only if the total float is absorbed by the delay.

SUBMITTAL PROCEDURES

PART 1 GENERAL

1.1 SUBMITTAL PROCEDURES

A. The word "submittals" shall be interpreted to include Work plans or procedures, Drawings, shop drawings, schedules, data, manuals, certifications, test reports, curves, samples, brochures, and other items furnished by CONTRACTOR for approval, information, or other purposes.

B. Each submittal will be returned within fourteen (14) calendar days following receipt of submittal, unless otherwise indicated in the Specification section. Resubmittals shall be subject to the same review time.

C. Do not perform Work related to submittals prior to obtaining the required approval from

CONTRACTING OFFICER OR CONTRACTING OFFICER’S REPRESENTATIVE.

D. Utilize a 9-character submittal identification numbering system in the following manner:

1. The first five digits shall be the applicable Specification section number.

2. The next three digits shall be the numbers 001 to 999 to sequentially number each initial separate item or submittal under each specific section number.

3. The last character shall be a letter (A to Z) indicating the submission, or resubmission of the same Submittal, i.e., “A = 1st submission, B = 2nd submission (first resubmission), C = 3rd submission, etc. A typical submittal number would be as follows: 02617 - 008 - B.

E. Submittals will be reviewed no more than twice at CONTRACTING OFFICER or CONTRACTING OFFICER’S REPRESENTATIVE expense. Subsequent reviews will be performed by CONTRACTING OFFICER OR CONTRACTING OFFICER’S REPRESENTATIVE at CONTRACTOR’s expense. CONTRACTOR will be invoiced on a time and materials basis using the same hourly rates that are being charged to CONTRACTING OFFICER for engineering services. Invoice amounts will be deducted from amounts due, or to become due, to CONTRACTOR. Submittals are required until approved. Delays resulting from resubmittals will not entitle CONTRACTOR to a Contract Time extension or change in Contract Price.

F. If the items as submitted describe variations and show a departure from the Contract requirements which CONTRACTING OFFICER OR CONTRACTING OFFICER’S REPRESENTATIVE finds to be in the interest of CONTRACTING OFFICER and to be so minor as not to involve a change in Contract Price or Contract Time, CONTRACTING OFFICER OR CONTRACTING OFFICER’S REPRESENTATIVE may return the reviewed submittals without noting an exception.
