The existing pipeline is undersized and should be upsized to increase the carrying capacity. The existing pipeline currently connects to a system on Provine Street and outfalls into an existing 54-inch storm drain that connects to Fosdic Lake. As authorized in SA#2, AECOM presented a revised conceptual design utilizing Other Than Open Cut methods of construction. Additionally, recommendations on methods and materials required for this type of installation were evaluated and presented within the Technical Memorandum submitted January 24, 2011. Subsequent to the City review of said Tech Memo a site meeting was held on March 4, 2011. The result of this site visit was the direction that the existing alignment is to be abandoned. A new alignment was determined that would allow open cut installation. AECOM is prepared to move forward with the redesign to incorporate this newly identified alignment. The new alignment will require efforts that are additional to the current contract including SA#1 & SA#2. The purpose of this memorandum is to enumerate these additional efforts and to request additional services and fees. This memorandum describes the tasks that are necessary for the revised design of the storm drain that are considered additional effort to the original contract, SA#1 or SA#2. These tasks are provided in detail below, the total fee to perform the work described below is $22,565. A total fee breakdown associated with the tasks is shown in Attachment 1. Attachments 2 shows a breakdown of costs associated with the additional surveying and SUE for the amended project alignment. Exhibit 1 shows the modified corridor as discussed in the March 4, 2011 site meeting. Task 1.0 Project Management • Task 1.1 &1.2 -Project Management—AECOM will provide on-going project management throughout the project to coordinate components of the project with the City and with the subconsultants.

This item is accounted for in subtasks 1.1 & 1.2. The fee required to perform this task is$6,940. • Task 1.3-Prepare Tech Memo on Other Than Open Cut(OTOC)—Under SA#2 AECOM was to evaluate the installation of the storm drain by OTOC methods. The original SA#2 request contained scope and fee to prepare a tech memo on OTOC.This item was requested to be removed from SA#2; AECOM removed this item as requested. Subsequent to the approval of SA#2 it was requested that AECOM submit a Technical Memorandum on the evaluation and recommendation of OTOC. Therefore, AECOM request that this additional effort be included in the scope of SA#3. The total effort for this service is maintained as per previous request and the required is$1,790. Task 2.0—Preliminary Design (60%) • Task 2.3-SUE Analysis—AECOM has retained a SUE-specialized firm for this analysis which will be conducted for the alignment between Provine and the outfall. This work will include a Level B SUE to locate the horizontal and vertical locations of the utilities. The fee required by the SUE firm to perform this task is$5,000 (Attachment 2). The total fee to provide this service is$5,895,which includes coordination efforts through AECOM. • Task 2.4-Revise Storm Drain Alignment from Provine to Ederville—AECOM will revise the proposed storm drain alignment from Provine to Ederville based on the amended alignment as discussed during the field review meeting referenced above. A revised alignment will be presented for approval prior to progressing the preliminary design for the revised alignment. The deliverable for this phase of work will conform to the requirements of the existing design scope. AECOM estimates that the additional fee required to perform this task is$2,065. Task 3.0—Final Design Task 3 effort remains unchanged. Task 4.0—Construction Phase Services Task 4 effort remains unchanged. Task 5.0—ROW/Easement Services Task 5 effort remains unchanged.
