==108.7.1 Extensions or Adjustments of Time==
[https://www.modot.org/missouri-standard-specifications-highway-construction Sec 108.7] provides a basis for granting adjustments, suspensions or extensions of time when progress is adversely affected by items beyond the contractor's control. Sec. 108.7.1 covers extensions of time for calendar day or calendar date contracts and refers to weighted time tables on file in the office of the Commission. Weighted timetables (for contracts with and without time exclusions) and examples of proper use are shown in [[:Category:108 Prosecution and Progress#108.7.2 Table for Contracts with No Time Exclusion|Tables 108.7.2]] and [[:Category:108 Prosecution and Progress#108.7.3 Table for Contracts with Time Exclusion|108.7.3]] and [[:Category:108 Prosecution and Progress#108.7.4 Examples|EPG 108.7.4 Examples]].

Such requests should be evaluated by the [[:category:105 Control of Work#105.9 Authority and Duties of Resident Engineer (Sec 105.9)|resident engineer]] and sent to the District Engineer along with a detailed study and recommendation. The district may discuss the request with  [http://sp/sites/cm/Pages/default.aspx Construction & Materials] before rendering a decision. Requests from the contractor for major adjustments, suspensions, or extensions of time require thorough study by the resident engineer. In many cases the basis for the request is not subject to a clear-cut policy decision.

It is necessary that these procedures be followed to ensure uniform administration of the liquidated damage provisions of our contracts.

When it is not possible to grant the contractor's request, a thorough report should be sent to Construction & Materials to recover liquidated damages.

===108.7.1.1 Assessment of Liquidated Damages and Exceptions===
<div style="float: right; margin-top: 5px; margin-left: 15px; width:435px; font-size: 95%; background-color: #f8f9fa; padding: 0.3em; border: 1px solid #a2a9b1; text-align:left;">

</div>

Contract time for project completion should be administered in accordance with [https://www.modot.org/missouri-standard-specifications-highway-construction#page=4 Sec 108.7] as well as all applicable job special provisions.  At a minimum, all contracts should have a JSP for Contract Liquidated Damages that identifies the time limits along with penalties for both Road User Costs and Contract Administrative Costs.  A [https://epg.modot.org/forms/CM/Liquidated_Damages_Guidance.pdf  guide for assessment of liquidated damages] is available.

Contract time for specific milestone events, such as a road closure, should be administered as specified in the contract Liquidated Damages Specified JSP for that event.  Sec 108.7 does not apply to specific milestone events, therefore, liquidated damages are generally charged 7 days/week with no waivers for weekends and holidays.  Refer to the terms in the contract Liquidated Damages Specified JSP and administer accordingly. 

Measurement of contract time for project completion ends when the contractor completes all work, including all corrections listed on the Semi-Final Inspection Form (C-236).  The RE sometimes lists “exceptions” on the form.  Exceptions are tasks or acceptance periods that are contractually allowed to occur after the contract completion date without penalty. For a list of common exceptions, refer to [[:Category:105 Control of Work#105.15.1.2 Exceptions|EPG 105.15.1.2 Exceptions]].  Some exceptions may require a date range attached to the task.  For example, removal of the Point of Presence signs should be done approximately 90 days after the semi-final inspection, so the RE should specify a two-week period for the POP sign removal, approximately 90 days out. As that date approaches, the RE should remind the contractor of the looming deadline to remove the signs to avoid having the count of time reinstated and damages assessed.

More details are available in the following Quick Reference Guides: [[:Category:101 Standard Forms#CO Milestones|Milestones]] and [[:Category:101 Standard Forms#CO Contract Times|Contract Times]].

===108.7.1.2 Consideration of Time Extensions or Suspensions===
Contractors are presumed to have made provisions in their bids for any anticipated delays in procurement of materials. Contract time extensions or suspension of working days should not be based on unsupported claims of delays in delivery of materials. Consideration may be given to delays caused by unusual market conditions such as an industry-wide strike, natural disaster, or area-wide shortage that arises after award of the contract and prevents procurement of materials within the allowable time for contract completion. It will be necessary to evaluate any claim for time extension based on material shortages to determine if the delays were, in fact, beyond the control of the contractor or the fabricator.

===108.7.1.3 Progress Schedules===
Per [http://www.modot.org/business/standards_and_specs/SpecbookEPG.pdf#page=4 Sec 108.4], the contractor is required to provide the Resident Engineer with an initial Progress Schedule prior to or at the pre-construction meeting. The request for the initial schedule is included in the [https://epg.modot.org/forms/CM/PreCon_Letter_Federal.pdf Pre Con Letter-Federal] and [https://epg.modot.org/forms/CM/PreCon_Letter_State.pdf Pre Con Letter-State].  Contracts are generally set up as Completion Day or Completion Date projects; however, there may be some rare instances where a contract will be set up as a Working Day project. Regardless of the method of contract time, the progress schedule shall include an activities bar chart showing the major items of work throughout the life of the project. The initial Progress Schedule is very critical in establishing the basis for the planned work and should account for all limitations that are known at that point in time. It should be thoroughly reviewed for compliance with Sec 108.4, should demonstrate continuous prosecution of the work, achievement of any required milestones and indicate overall project completion within the allotted time. Acceptance of the initial Progress Schedule, and all subsequent progress schedules, will be made by the Resident Engineer.
 
Once the initial schedule is accepted, if the work plan changes or the contractor falls significantly behind schedule, the Resident Engineer should require a revised schedule be submitted in accordance with Sec 108.4.2.1 and Sec 108.4.4. The revised schedule should clearly show a plan to ensure project completion within the allowable time.  Likewise, should an excusable delay occur, the RE should issue the appropriate time adjustment change order and require a revised schedule.

If progress towards completion within the allowable time is in jeopardy, and the cause is due to inexcusable failures by the contractor (see common failures below), a letter should be submitted to the contractor, with a copy to the surety, informing them of the possibility of being declared in default of the contract if the contractor does not proceed with a remedy within ten days of the notice.  The State Construction and Materials Engineer should be informed of this notice.  If after ten days the contractor has not adequately proceeded with a remedy, the State Construction and Materials Engineer will work with the district and the Chief Counsel’s office to determine the next course of action, which may include declaring the contractor to be in default.

Common contractor failures that could affect schedule and lead to Default of Contract:
:1. Failure to mobilize and begin work on time.
:2. Failure to provide sufficient resources (workers and/or equipment) to maintain sufficient progress.
:3. Unacceptable work that requires extensive time to repair or replace.
:4. Contractor delay caused by a refusal to remedy work deemed unacceptable.
:5. Contractor vacates project or discontinues work on the major operation.
:6. Contractor fails to return to the project in a reasonable time following a stoppage of work.
:7. A stoppage of work is issued for non-compliance with a contract requirement.
:8. A federal and or state legal action taken against the contractor.

====Two-Week Schedule====
In addition to maintaining a current project Progress Schedule, each week the contractor is required to provide the Resident Engineer with a dynamic two-week look-ahead schedule.  This two-week schedule is the basis (i.e. agenda) for discussion at the weekly progress meetings.  It provides current details that are important in planning and scheduling resources over the following days, including upcoming traffic control changes and inspection resources.  This schedule is very important for coordination efforts.  It can be in any format acceptable to the RE, but should not be waived except during planned pauses or low activity levels in the work and the RE agrees it is not necessary.
