Section 3 — Understanding of Need S ✓ Analysis of issues: change order impacts or potential problems on schedule and budget progress, time of completion, weather/rain days, delays and time extensions, and submit to contractor and the City on a weekly basis. The weekly statement of working days is typically discussed and agreed upon at each progress meeting and transmitted as an attachment to the minutes. Schedule Review: W&A is very familiar with the mainstream scheduling software used by the public works contracting industry including, but not limited to, Primavera P70, Suretrak® and Microsoft Project®. The W&A Inspector will review the baseline construction schedule, including activity sequences and duration, schedule of submittals and schedule of delivery for products with long lead-times. The schedule will not be approved as the baseline until all discrepancies are resolved. The CM team will evaluate the baseline project schedule for the following: ✓ Consistency with the contract schedule (completion within the contract time) ✓ Accurate start dates, completion dates, other dates detailed in the contract ✓ Any impacts of weather and change orders ✓ Sufficient detail — including submittal process and procurement requirements ✓ Sequence of construction and correct schedule logic ✓ Identification of the critical path and project float ✓ Cost spread allocation Schedule Control: During the progress of construction, the W&A team will compare the contractor's monthly schedule updates to the baseline schedule and any approved time extensions, note any shortcomings and monitor and track corrections by the contractor to keep the project schedule on track. A four week `look -ahead" schedule will be required from the contractor, updated weekly and presented at the weekly construction progress meetings. This tool will keep the entire team looking one month ahead of the project and will facilitate proactive handling of project activities and issues. If necessary, W&A will negotiate time extensions due to change orders or other delays. Photographs: W&A will prepare and maintain an electronic photo journal documenting the construction progress. Photos will be taken before construction begins, during construction and upon completion of the project. The project will be videoed as well for full capture of all detail prior to construction starting. This is important at the individual residences with separate agreements with the City for easement work. Contract Conformance: W&A will visit the site during the normal working hours (and when critical activities warrant it) to verify construction progress and to verify that all work conforms to contract requirements. Deputy and special inspection and materials sampling and testing will be coordinated and provided as required by the final plans and specifications. W&A will reject work that does not conform to the requirements of the contract documents and will promptly report unacceptable work to the City and contractor. Rejected work will be thoroughly documented, photographed, and tracked until repaired or replaced to the satisfaction of the City. QA/QC: W&A will enforce the quality assurance plan, in conformance with the City's Quality Assurance Manual, or as developed by W&A and the City for the specific needs of the project prior to the start of work. W&A will perform and/or coordinate QA/QC activities daily and review activities as they happen, to make sure that QA/QC procedures are followed, and deficiencies are resolved in a timely and efficient manner. The CM will maintain a chronological log of all records. Change Orders: W&A will establish, implement, and coordinate systems for processing all contract change orders. Each issue which is identified as a potential change to the design, scope, cost or contract time will generate a change notice. The CM will determine whether a change notice should be considered. The plans and specifications will be reviewed against the change notice. If the issue does not appear to be included in the plans or specifications, a Request for Quotation (RFQ) will be sent to the contractor. Any credits for work deleted because of the change will be required then as well. The contractor's response to the RFQ will be evaluated for reasonableness and completeness. The CM will maintain a Trend Log, listing potential changes as identified, either formally or informally. This Trend Log will be used such that potential change items are not overlooked or deferred until the end of the job. W&A will prepare independent cost estimates as required for contract change orders. Upon approval by the City, the Inspector will prepare, log and process change orders for full execution, and administer their implementation. Once fully executed, the CM Team will review the timely completion of the work and coordinate inclusion of the change order in the appropriate payment application. V111acepAssociates ....
