RECOMMENDED ACTION A. Move to: 1. Approve Task Order 10018a with CH2M HILL for Additional Office Services and Construction Staking for the Bittercreek Lift Station and Pipelines Project, for anot-to-exceed cost of $44,300. 2.

DEPARTMENT CONTACT PERSONS Place names, titles, and phone numbers of the Persons involved in Descending Order: Tom Barry, Director of Public Works 489-0372 Warren Stewart, PW Engineering Manager 489-0350 Clint Dolsby, Asst. City Engineer (Project Manager) 489-0341 III. DESCRIPTION A. Background The Bittercreek Lift Station and Pipelines Project will provide sewer service and fire flows to the Bittercreek subdivision. This lift station is expandable to serve additional developments in the future. The wastewater lift station is located near the intersection of Amity and Lindy Roads adjacent to the Bitter Creek development. The pipelines include new dual sanitary sewer force mains (6- and ~® o Page 1 of 3 10-inch diameter), a new 21-inch diameter gravity sanitary sewer pipe and a new 16-inch potable water main. B. Proposed Project This task order will enable CH2M HILL to provide additional office support services for the Bittercreek Lift Station and Pipelines Project Construction Project. Their scope of services has increased from submittal review to include construction staking, site visits including attendance an onsite meetings and an as- built survey of the gravity sanitary sewer and lift station wet well. C. Consultant Selection The consultant selected for this project was procured for the design and office supports services to date. This consultant was chosen due to their familiarity with the project and quality of the work they have completed on this project. IV. IMPACT A. Strategic Impact: This activity aligns with our department's mission of providing modern and reliable facilities. B. Service/Deliver~ acct: Currently, the Bittercreek Subdivision utilizes a City Well for water supply and lagoons for wastewater treatment. The well does not supply adequate fire flows to the homes in this subdivision. The completion of the Bittercreek Lift Station and Pipelines Project will provide City sewer services and fire flows to the Bittercreek Subdivision. C. Fiscal Impact: Project Costs Consultant Agreement Time and Materials Not-to-exceed $44,300 Total Time and Materials Not-to-exceed $44,300 Project Funding Project will be funded from lift station construction (3590-96144) $44,300 V. ALTERNATIVES A. The City could defer this task order which would likely result in delays in the construction schedule and/or additional change orders for the construction project. Outcomes of these delays could manifest in standby changes from the Page 2 of 3 contractor, extension of contract times, demobilization and remobilization expenses and other associated fees. This alternative would greatly limit the ability to complete this project. B. City staff could work with JLJ Enterprises and their selected representative, The Land Group, to incorporate selected tasks outlined in the task order into their scope of work. Since the Land Group was not the design engineer on this project and has not been actively involved in the construction management to date, this would likely result in more coordination, staff hours, and potentially higher fees from the Land Group to perform this work since they would first need to get up to speed with the project. VI. TIME CONSTRAINTS Council's approval will allow the continued office support services for the construction project. VII. LIST OF ATTACHMENTS A.

I Dq' Dat ~Ig~~ Date Task Order 10018a Attachment A Additional Office Services and One-Time Construction Staking Project Understanding The City of Meridian (City) would like CH2M HILL to perform additional office services, initial (one-time) construction staking as requested by Eastern Oregon Construction, LLC (Contractor), and an as-built survey of the gravity sanitary sewer and lift station wet well in support of the Bitter Creek Lift Station and Pipelines project. The additional office services provide for expanded support to City staff based on efforts performed to date and anticipated future efforts. The wastewater lift station is located near the intersection of Amity and Lindy Roads adjacent to the Bitter Creek development. The pipelines to be staked include new dual sanitary sewer force mains (6- and 10-inch diameter), a new 21- inch diameter gravity sanitary sewer pipe, seven (~ new sanitary sewer manholes, and a new 16-inch potable water main. The dual sanitary sewer force mains and gravity pipe portion originate at the new lift station, run north to Amity Road, thence east along Amity Road to the intersection with W. Ten Mile Road, thence north along W. Ten Mile Road to terminate at the new Overland Road re-alignment (new intersection for the Southridge development) for a total combined length of approximately 2.7-miles. The potable water main originates by the W. Amity Road and S. Nickel Creek Place intersection, run east along Amity Road to the intersection with W. Ten Mile Road, thence north along W. Ten Mile Road to terminate at the new Overland Road re-alignment (new intersection for the Southridge development) for a total length of approximately 2.1-miles.
