HomeMy WebLinkAboutTask Order No. 10162A with CH2M Hill for WWTP Blower ReplacementPURCHASING AGENT 33 E. Broadway Ave, Meridian, ID 83642 Phone: (208) 888-4433 x 417 Fax: (208) 887-4813 TASK ORDER NO. 10162A Between CITY OF MERIDIAN AND CH2M HILL This Task Order is issued by City and accepted by the Engineer pursuant to the mutual promises, covenant and conditions contained in the Master Agreement between the above mentioned parties dated April 13, 2010. Meridian WWTP Blower Replacement Task Order 10162A PAGE 1 OF 10 Project Understanding The City plans to replace the existing multi-stage aeration blowers located at the Meridian Wastewater Treatment Plant (WWTP) with two high-speed, turbo blowers. This new, more efficient blower system will significantly reduce the power requirements at the WWTP. In addition, a new dissolved oxygen (DO) control system is planned as part of this expansion. The City has already completed a significant amount of work in developing this project. The City has worked with Idaho Power to receive assistance in funding this Project. The Department of Energy has also provided a grant to assist with this purchase. A primary goal of this project is to have the retrofit complete and in operation by October 2010. Scope of Work CH2M HILL will perform tasks for the development of design documents for the installation of the high-speed, turbo blowers at the Meridian WWTP. This scope of work presents the tasks associated with assisting the City of Meridian with replacement of their existing multistage aeration basin blowers with two more efficient, 200-HP turbo blowers. Design assumes that the new high efficiency blowers will be housed in an existing blower room, and powered from the existing plant power distribution system. The blower room structure will not be modified for blower installation beyond construction of new equipment pads for blower mounting. The plant electrical distribution system will not be modified beyond provision of a new power distribution panel, or new branch circuit breakers, to feed the blowers. CH2M HILL will also provide assistance during the construction phase of the project, providing submittal reviews and attending progress meetings with the City and Contractor. CH2M HILL will complete record drawings once the installation is complete and accepted by the City. Task 1-Project Management 1.1 Staff Management and Task Coordination Project management will consist of supervising project staff, holding consultant staff coordination meetings, documenting meeting decisions and action items, and assigning activities to team members. 1.2 Monitor Project Progress Monitor project progress, including work completed, work remaining, budget expended, schedule, estimated cost of work remaining, and estimated cost at completion. Monitor project activities for potential changes, anticipate changes when possible, and with City approval, modify project tasks, budgets, and approach. 1.3 Invoices PAGE 2 OF 10 Prepare and submit a monthly billing. Prepare invoices for services performed on a monthly basis, including a brief summary of work completed. 1.4 Project Quality Control Perform project quality control reviews of all deliverables on this project. Senior technologists will be involved in the work tasks and perform necessary reviews at deliverable milestones. 1.5 Schedule Evaluation An evaluation of the anticipated project schedule will be prepared for the 60% design and 90% design submittals to the City. The schedule evaluation will include the remainder of design tasks to be completed, bid and award, equipment delivery (if long lead time), and construction schedule. Task 1 Assumption: None Task 1 Deliverables: • Estimated Project Schedule (60%, and 90% design submittals) Task 2-High-Speed, Turbo Blower Sizing Review 2.1 Blower Sizing Review This task shall review the CITY's evaluation and associated size of high efficiency blowers required to replace the existing aeration basin blowers located at the CITY's WWTP. The analysis assumes that the control of the system-will not change from its current mode of -operation. Installation of a different control system is beyond the scope described herein. CITY may have the option of modifying air flow by controlling the variable frequency drives of the new high efficiency blowers. This operation would also be a manual operation and not driven by any new control devices. Task 1 includes one site visit by mechanical and electrical engineers (two CH2M HILL staff total). Task 2 Assumption: • CITY to furnish future influent flow and load projections and historical influent flow/load, process control data, and blower sizing evaluations (as Microsoft Excel® electronic files if applicable). Task 2 Deliverable: • Correspondence detailing engineering review in electronic format PAGE 3 OF 10 Task 3-Coordinate with Idaho Power and Review ESCOR Proposal Assist City of Meridian with the coordination of grant funding available from Idaho Power. Task 3 assumes 2 meetings with Idaho Power and one CH2M HILL staff member. It also includes a review of their power and cost calculations. CH2M HILL will review the Roots Control System proposal (ESCOR proposal) to determine its applicability for the Meridian WWTP. Coordination requirements between this control system and the blower installation will be presented. Task 3 Assumptions: • CITY to furnish historical power consumption data along with Idaho Power proposal, as Microsoft Excel® electronic files if available. • CITY to furnish ESCOR proposal Task 3 Deliverables: Memorandum detailing review of Idaho Power requirements and ESCOR Proposal (sent to CITY electronically) Task 4-Develop Bid Package 4.1 Preliminary Engineering Report A Preliminary Engineering Report summarizing the preliminary design effort will be prepared in accordance with IDAPA 58.01.16, Wastewater Rules and submitted to IDEQ. CH2MHILL will submit the draft report to the City for review. Review comments will be incorporated and two copies will be submitted to IDEQ Boise Regional Office for review and approval. As per a discussion with IDEQ, the Preliminary Engineering Report will be submitted together with the Contract Documents once the design is complete. 4.2 75% Design Documents Preparation CH2M HILL will produce approximately 75% complete drawings and specifications. Specifications will be prepared using CH2M HILL standard specifications including CH2M HILL standard front end specifications. Aproject review meeting will be held following the City's review of these documents. 4.3 Final Fix-up and Contract Documents Preparation CH2M HILL will provide final fix-up of the drawings and specifications based on the City's comments from the previous Subtask. Bid documents, in the form of and one set of electronic files and 4 sets of printed documents (drawings printed at half-size), will be delivered to the City. Electronic bid documents will be delivered in Portable Document Format (PDF). 4.4 Agency Approval CH2M HILL will deliver a stamped set of the final bid documents to IDEQ for agency review and approval. It is assumed that any necessary changes to the contract documents, as required by IDEQ's review comments, would be effected by addendum during the bid phase of the PAGE 4 OF 10 project. It is noted that the IDEQ review period may be as much as 42 calendar days from the time of submission to the agency. 4.5 Project Review Meetings Four copies of 75% complete project documents will be provided for the owner's review and comment.
