SUGGESTIONS OR SPECIAL CONCERNS THE CITY SHOULD BE AWARE OF F. VALUE ADDED RELATED SERVICES In addition to the above scope items, Stantec proposes the City consider the following additional related services. These value added services are not included in our fee schedule, upon request we will provide an additional fee schedule for any items the City decides to include. 1. 3D Renderings Stantec can prepare three-dimensional renderings of up to ten views of the PFAS treatment system design for a given site for use in City presentations or public stakeholder meetings to illustrate the visual look and feel of the new facilities. 2. DDW Permit Assistance Amended Permit Assistance: In close coordination and with information and input from the City for specific topics, we can prepare an engineering report for DDW permit amendment for the planned system modifications to be submitted by the City. This review will evaluate the system background and recent analytical history, purpose, and reason for system changes, proposed treatment equipment additions, chemical additions, conveyance changes, and anticipated operational changes. Stantec will respond to and incorporate one round of DDW comments and attend two meetings with DDW. Operations Maintenance and Monitoring Plan (OMMP): Stantec can prepare an updated OMMP in coordination with the City for the new treatment system, which is required by DDW to obtain the amended permit. Stantec will prepare a draft version of the OMMP for submission by the City to DDW, and Stantec will respond to and incorporate one round of DDW comments and attend two meetings with DDW. 3. Electrical Equipment Replacement As encountered during the OCWD on -call contract, many of the City's existing well sites are powered by aged electrical equipment that may be either undersized for the new electrical demands, or past its useful service life. As seen in the Well 26 record drawings provided with the RFP, the existing Motor Control Center (MCC) is more than 50 years old. While this MCC appears to have adequate capacity for the addition of a booster pump, it would likely prohibit the addition of at least one of the 125 horsepower future pumps. It is our experience that the City generally prefers to upgrade this older equipment. As such, Stantec can replace the Well 26 MCC with new electrical equipment as part of the design. 4.Chemical System Upgrades It is unclear from the Well 26 record drawings what type of chemical disinfection systems are present and what their current state is. If the equipment is in need of replacement, then we can incorporate a similar system as provided at the City's Well 38. 5. Construction Inspection Services As is currently being provided for the construction of Well 40, Stantec can provide part-time construction inspection services and special inspection services (compaction results, concrete compressive strength testing, welding inspection, and structural observations). These services would relieve the time requirements for City staff during construction. 6. Prepurchase Procurement Package for IX System and Emergency Generator Stantec can prepare technical specifications to support the prepurchase of IX vessels and/or an emergency generator for a given site. This will be a single procurement package. The City will provide their standard purchase agreement, front ends, and request for proposal and Stantec will assist with compiling a complete and coordinated procurement packages for bidding. Stantec will answer technical questions during bidding and provide a technical evaluation of submitted bid proposals.
