HomeMy WebLinkAboutChange Order No 1 for WRRF Headworks Capacity Expansion with CH2M HillCITY OF MERIDIAN CHANGE ORDER NO. 1 33 EAST BROADWAY PROJECT NO, 10044 MERIDIAN, ID 83642 DATE: 10/27/15 EFFECTIVE DATE: 11/4/15 TASK ORDER CHANGE ORDER ENGINEER/CONSULTANT: CH2M Hill Engineering, Inc. PROJECT: WRRF Headworks Capacity Expansion Phase 1 Design FY15 The Engineer/Consultant is hereby directed to make the following changes from the Task Order Documents. Description: The Headworks Capacity Expansion Project design spans over FY15 and FY16. Phase 1 of the design phase included all work performed in FY15. Phase 2 of the design phase will include all work performed in FY16. CH2M HILL provided and completed engineering services for Phase 1 and will continue with Phase 2 of this project design. Phase 1 design included preliminary analysis and 30% design documents. Phase 2 design takes the 30% plans to bid ready design plans. Reason for change order: Due to the design project spanning over two fiscal years, it was decided to break the task order into the FY15 project phase and the FY16 project phase. Also by negotiating this change order after 30% drawings were complete, CH2M Hill would have a better understanding of the required costs to complete the design plan set. This amendment to the task order represents the remainder of the design phase requirements for the project that were budgeted for FY2016. q Attachments: Scope of Services (1b pages) CHANGE IN TASK ORDER PRICE: CHANGE IN TASK ORDER TIMES: Original Task Order Price $231,285.00 Original Task Order Times: 90 Net changes form previous Change Orders Net changes form previous Change Orders No._0^ to 1_ No._ to _ (calendar days) $0.00 0 Task Order Price Prior to this Change Order: Task Order Times prior to this Change Order.

(ENGINEER) WRRF - HEADWORKS CAPACITY EXPANSION PHASE 2 DESIGN FY16 ENGINEER is currently engaged in the execution of Task Order 10044 in support of the Wastewater Resource Recovery Facility Headworks Capacity Expansion project. ENGINEER is following a traditional step -wise, phased approach to performing the work associated with design of the UV system. The project design approach consists of: • Project Chartering and Site Visit (Phase 1 Scope) • Project Definition (Phase 1 Scope) • Preliminary Engineering and Design (30 Percent Design — Phase 1 Scope) • Design Development Documents (60 Percent Design) • Final Design Documents (90 Percent Design) • Bid -Ready Documents (100 Percent Design) • Bid Period Services — assist City with bid process for selecting a general construction contractor The project is being delivered in two phases to align task order budget with City fiscal year budgets. Per the list above, Phase 1 carries the project through the Preliminary Engineering and Design task and Phase 2 will advance the project through Bid Period Services. The initial Task Order 10044 is considered Phase 1 and this Change Order No. 1 constitutes Phase 2. The tasks associated with this Change Order No. 1 are more fully described in the Scope of Work section below: SCOPE OF WORK Task 1 — Project Management (Additional) Additional project management will be provided by ENGINEER to manage, coordinate and lead ENGINEER Team's activities and perform administration of the project design services and project quality reviews. ENGINEER will provide the resources necessary for project management throughout this phase of the project as described in the initial Task Order 10044. Change Order No. 1 to Task Order 10044 Page 1 of 9 WRRF — Headworks Capacity Expansion Design and Bid Services CH2MHILL Engineers, Inc. Deliverables • Periodic written project design schedule updates to keep the City's Project Manager informed as to the changes to the initial schedule outlined in this Scope. • Monthly project invoice statements with a brief description of the work performed.
