Fax: (208} 887-4813 TASK ORDER NO. 10160 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. Wastewater Treatment Plant Tertiary Filters Building Design and Services During Construction Project Understanding The City of Meridian is pursuing construction of a new building(s) to enclose the four existing tertiary filters located at the wastewater treatment plant to provide protection from the elements for the equipment and freeze protection. The design team is to determine an appropriate building layout and foundation design suitable for enclosing the existing filters and minimizing impact to the existing plant infrastructure and underground utilities. Furthermore, the team is to design the necessary mechanical and electrical systems to support the buildings}. The City has indicated that the four existing filters can be enclosed in one large building or multiple smaller buildings depending on site constraints and cost benefits. A fifth filter may be added at some point in the future south of Filter #4 and is to be considered during this design phase to allow for building expansion or a separate, stand-alone building. PAGE 1 OF 15 The design, permitting, and construction of the new building{s) is targeted to be complete and turned over for occupancy by the end of September 2011 coincident with the end of the 2010- 2011 City fiscal year. City Council has approved total budgetary funding of $1,250,000 for the design and construction of the new building(s). The City has indicated that the new buildings} do not require a robust HVAC system to heat and cool the enclosures}, but must maintain temperatures above 35-degrees in the winter and allow for cross-ventilation in the summer. Furthermore, the City has indicated that odor control is not required for the new building(s). Proper ventilation needs to be provided for the building(s) to allow for adequate air changes to avoid moisture build-up and minimize the potential for corrosion of steel frame members. The mechanical ventilation system is to be the minimum required to achieve the stated objectives. The City is open to material (e.g. masonry, metal) to be used for the building construction and desires the most economical solution that can be constructed within the allotted time frame. Based on the existing underground obstructions that must be avoided with respect to the building foundation, it appears that a metal building(s) is best suited for this installation and will satisfy the stated conditions. Therefore, the scope of work and associated compensation are based on designing a metal buildings}. An additional requirement is that the building colors selected match the existing building colors located thzoughout the plant. Consideration and accommodations are to be provided in the building design to allow access for equipment maintenance of the pumps, motors, and filters. It was discussed that roll-up doors on either end of the building(s) would suffice with a possible need for removable skylights located above the vertical turbine pump motors at Filters #1 and #2 to allow for crane access to remove the motors. Horizontal clearance around the existing equipment needs to be provided to allow for personnel movement on the order of 3-feet at a minimum. Vertical clearance above the equipment needs to be provided to allow for maintenance activities on the order of 6- to 8-feet. The pump and filter equipment is currently wired into the plant SCADA system and is to be maintained. Controls for air handlers and other building operation equipment can be stand- alone for the individual buildings} and does not need to be wired into the plant-wide control system. The electrical design will address providing power for the new HVAC, lights, and receptacles for the building{s) and does not account for any modifications to the electrical service feeds for the existing process equipment. The Ciry indicated that the building(s) do not need to have personal safety provisions such as eye wash stations and showers. Potable water does not need to be plumbed to the building(s).
