The Contractor shall submit the progress update diagrams, reports, tables, and graphs specified in paragraph e. of this paragraph with each request for progress payment documenting the progress of work as of the end date of the progress payment period.
(4) The Contractor shall submit a time impact evaluation (TIE)
(a) Within 30 calendar days after the COR directs a contract change;
(b) With any proposal for a future modification;
(c) With any value engineering proposal, or
(d) With any request or claim for an equitable adjustment to the contract.
(5) Within 7 calendar days after receipt of Notice to Proceed, the Contractor shall designate in writing a qualified and experienced scheduling engineer who shall be responsible for working and coordinating with the COR for the development and maintenance of the Construction Program.
c. Detailed logic diagrams and work breakdown structure. ‑
(1) The Contractor shall develop detailed logic diagrams based upon methods for performing the work in compliance with the contract requirements. The Contractor shall assure that all subcontractor work, the Contractor’s work, Government interfaces, and all contract milestones are included in the detailed logic diagrams.
(2) The Contractor shall define a WBS identifying each process, facility, structure, system, location, or elevation for which specific authority and responsibility for completion will be assigned. The individual work packages present at the lowest level of each branch of the WBS shall be placed in a separate subnetwork of the detailed logic diagrams with unique subnetwork coding. Concrete placements as described in the Concrete, General paragraph of this contract shall be coded and shown as a separate subnetwork.
(3) Activities for the detailed logic diagrams shall be defined to a level of detail resulting in their durations being no greater than 15 workdays or 20 shifts unless otherwise approved by the COR. Durations for administrative activities, (e.g., submittals and reviews), fabrication, or other specific activities identified in the contract will not be subject to the 15 workday or 20 shift limitation. The detailed logic diagrams shall specifically include activities for COR reviews and approvals identified by the RSN as listed in submittals requirement paragraph. Only finish to start time constraints between activities shall be used.
(4) Provide a legend and table of all abbreviations used in the detailed logic diagrams. The table of abbreviations shall list alphabetically all abbreviations used in the detailed logic diagrams and explain their meaning.
d. Baseline schedule and reports. ‑
(1) The Contractor shall include in the database the estimated duration for each activity.
(a) Estimated durations shall be shown in units of whole workdays and shall reflect the Contractor's best estimate of time required to complete the activity considering the quantity of work and planned resources for the activity. Durations of Government reviews and other identified actions shall equate to the maximum number of calendar days specified in their respective paragraphs.
(b) A workday calendar shall be established to translate the activity's workday duration, in a manner consistent with individual activity accomplishment, into appropriate calendar dates.
(2) The Contractor shall consider seasonal weather conditions in the planning and scheduling of all work influenced by high or low ambient temperatures or precipitation to ensure the completion of all work in compliance with the contract milestones.
(3) The baseline schedule shall meet all contract requirements and milestones, shall meet the funding constraints, and shall be scheduled considering the Contractor's own limitations of equipment, manpower, and material.

e. Progress updating. ‑
(1) The Contractor and CO's representatives shall meet monthly at the Government project office at a time mutually agreed upon by both parties for the express purpose of reviewing the actual progress made to date on the contract work as shown in the current schedule update. The review shall focus on the dates activities were actually started and completed and the remaining duration for each activity started but not completed during the period. In addition to the above, changes in logic and schedule shall be discussed and mutually agreed upon. Upon completion of the progress review meeting, the Contractor shall revise the update to reflect any changes mutually agreed upon at the review meeting.
(2) The Contractor shall report the current project status to the COR by providing the following diagrams, reports, tables, and graphs.
(a) A narrative report specifically stating the status of the project in terms of total float. If negative float exists, specific actions and conditions shall be cited which caused the "behind schedule" condition and the Contractor shall provide a course of action to complete the project within the delivery time specified in the contract. The report shall also include the following:
(aa) A listing of Contractor‑initiated changes to the current detailed logic diagrams or schedule stating the reason for the action taken. The Government reserves the right to disapprove Contractor‑initiated changes to the current detailed logic diagrams and schedule which negatively impact any Government action which was initiated on the basis of the current detailed logic diagrams or schedule.
(bb) Unresolved issues relating to the Construction Program.
(b) Updated total float report.
(c) 60‑day look ahead report which shall be a listing of all activities or milestones which are scheduled to start, finish or continue during the next 60‑day period.
