C&MS 109.09 Estimates 109.09 Estimates. If satisfactory progress is being made, the Contractor will receive monthly payments equaling the Work and materials in place. The monthly payment is approximate, and all partial estimates and payments are subject to correction in the Final Estimate and payment. Payment for Work and materials shall not, in any way, prevent later rejection when defective Work or material is discovered, or constitute acceptance under 109.11 or 109.12. Any pay item deficient in material approval can be withheld for payment on an estimate. C&MS 109.12 Final Acceptance B. Punch List. The Final Inspector will issue to the Contractor a written

punch list of work required as a condition of acceptance. For project involving multiple public agencies, the Final Inspector will receive and compile punch lists from all agencies that have authority to provide one prior to issuing the Departments punch list. The Final Inspectors punch list will stipulate a reasonable time to complete the required Work. Failure of the Contractor to complete the punch list items by the stipulated time will result in the assessment of fifty percent of the Liquidated Damages according to 108.07 for each Calendar Day for every day beyond the stipulated time the punch list work remains incomplete and beyond the revised Completion Date.

Revise Schedule Updates to have a data date of the first day of the current month, not the last day of the preceding month Allow the Department two more days to review a monthly schedule update Better differentiate the two types of schedule revisions Revisions on the critical path Revisions not on the critical path PN 132 CPM Progress Schedule for Design Build Multi-Season Projects Standardize a CPM Specification for all design-build projects. PN 132 contains language contractors have seen in our current CPM Specification, but with a different approach to schedule development.

Early in design-build projects, the plans are not developed and the level of detail is still pretty broad for buildable units. As the plans are further developed, the new note allows for more detailed construction schedule. Provisions are still in place for monthly progress updates, revision schedules, delay schedules and recovery schedules. The schedule is still a lump sum bid item with payments during the course of construction.

Take photographs showing initial condition, the daily progress of the work, unusual conditions, noncompliant work, and corrective actions. SS 878.04 (continued) A. Inspection

Inspection includes observations, measurements and verifications to ensure that: Preceding activities have been completed (e.g., 201, 202); Surface ready to accept material; Grading was checked - cross section, benching, typical section; Correct material provided, no debris; Spread to required lift thickness, not segregated;

SS 878.04 (continued) A. Inspection Compaction uses correct roller and number of passes; Correct moisture content maintained during compaction; Corrective actions taken to address failing tests or unstable materials; For 205 and 206: stabilization chemical applied at the required rate; chemical, added water and soil thoroughly

mixed; and the curing coat correctly applied. SS 878 Inspection & Compaction Testing 878.05 Forms and Weekly Reports. Provide accurate inspection information, tests, and calculations. Report inspections on Department forms to include a daily report and the construction quality documentation forms for the items inspected. Report the inspection and compaction tests on Department forms described in S-1015. Furnish the inspections, photographs, compaction test results, and measurements to the Engineer daily.

Supplement 1015 Compaction of Unbound Material Increased the compaction testing frequency to: Every Day Every Lift (except 611 and 503 backfill) 1015.09 Number of Tests. Divide the work into lots as shown in the following table. Perform the minimum number of compaction tests as shown in the table each day of material placement.
