DEVELOPMENTAL SPECIFICATIONS
FOR
CONSTRUCTION PROGRESS SCHEDULE
Effective Date
October 17, 2023
THE STANDARD SPECIFICATIONS, SERIES 2023, ARE AMENDED BY THE FOLLOWING
MODIFICATIONS AND ADDITIONS. THESE ARE DEVELOPMENTAL SPECIFICATIONS AND THEY
PREVAIL OVER THOSE PUBLISHED IN THE STANDARD SPECIFICATIONS.
Replace all of Article 1108.02, J, of the Standard Specifications with:
J. Construction Progress Schedule.
1. At the preconstruction conference, furnish the Engineer with a preliminary schedule. At least
5 calendar days prior to starting work; provide the Engineer with three copies of a satisfactory
construction progress schedule. In the schedule include, as a minimum, a chronologically
sequenced bar chart showing the proposed starting dates and durations, including the
estimated number of weather delay days, for each item of work. Also in the schedule: 1)
clearly show the controlling item of work for each day of the schedule, and the intended rate
of production for each item of work; and 2) include project staging, project required
milestones, and project suspensions that are 3 working days or longer.
2. Base the progress schedule on an adequate daily working hour schedule, with sufficient
materials, equipment, and labor being furnished to ensure completion of the contract within
the contract period. Commence and prosecute the work according to the accepted progress
schedule, with forces and equipment adequate to complete the controlling operations on
schedule.
3. The Engineer will use the progress schedule to identify controlling operations and as a check
on the rate of progress. The Engineer will jointly review the schedule with the Contractor at
least every 2 weeks to determine if progress is satisfactory. The Engineer may also request
the Contractor revise the schedule for any of the following reasons:
a. The project completion or intermediate completion targets are delayed 10 working days
or more.
b. The Engineer determines that the progress of the work differs significantly from the
current schedule such that it is unlikely the project will be completed within the contract
period.
c. A contract change order requires a revision of the Contractor’s work sequence or the
method of performing the work.
4. Prepare and submit revised progress schedules to the Engineer within 5 business days after
the request.
DS-23004, Page 2 of 2
5. The Engineer’s acceptance of the Contractor's progress schedules does not waive any
contract requirements.
6. Failure to supply the Engineer a satisfactory schedule or any revised schedule, progress
payments may be withheld until a schedule has been submitted and accepted.
7. No direct payment will be made for furnishing construction progress schedules or revisions.
The cost of the schedule is included in the cost of mobilization.

uploaded via web service / Application Programming Interface (API) to the agency.
2. Material ticket data will be submitted to https://iowa.dot-portal.io via an HTTPS POST as
JSON documents. Include the API key specific to each customer in each request as an HTTP
header.
3. Material supplier must test to confirm that ticketing data can be shared from the originating
system no less than 30 days prior to project start. Topic shall be discussed at the pre-
construction meeting.
4. Ticket data must be available immediately upon project start so there are no delays to
viewing tickets.
5. Provide the same data that is currently accessible and viewed by agency users previously on
printed tickets specific to state projects.
6. Transmit ticket data before the truck leaves the plant and transmit any updates to the ticket
data within 5 minutes of a change.
