The conceptual plans will be submitted with the third deliverable. Deliverable: • Pre-Final and Final Sustainability Report with all Tasks included APPROACH TO ANTICIPATED CONCERNS The team has considered potential concerns of problems that could occur during the duration of the project and integrated into our approach how we would resolve these to ensure successful project completion. Some concerns or items that may become issues based on our experience are lack of utility meter data, lack of detailed or incomplete as-built drawings, and changes of direction during analysis. Lack of utility meter data can be compensated for by using typical load profiles, however the future demand analysis and PV/ BESS calculations may be much more conservative and may not be accurate for the building, as it is non-specific to the building. Incomplete as-builts can be a challenge because we are unable to ascertain certain functions, requirements, or conditions that are not able to be seen during site surveys. We will make assumptions for these conditions or functions, but this may lead to calculations being conservative due to the unknown existing conditions. Finally, changes during analysis lead to rework that we do not account for in our budgeting; existing conditions impacts our analysis which impacts our recommendations. Our approach to minimizing disruptive changes is to break the deliverable into smaller portions, allowing the City to see smaller portions as they develop and provide comments to incorporate changes early. Deliverables: AECOM will submit the sustainability report to the City in four deliverables. Each deliverable will include the tasks/sections as outlines below, building upon the preceding deliverable. 1. 10% Draft Sustainability Report - Task 1 (Draft; PDF) 2. 50% Draft Sustainability Report - Tasks 1-4 (Draft; PDF ) 3. Pre-Final Sustainability Report - Tasks 1-6 (Pre-final; PDF) 4. Final Sustainability Report - Tasks 1-6 (Final; PDF) University of California, Riverside Campus Decarbonization Study and Climate Action Plan Riverside, CA AECOMs decarbonization study at UCR included evaluation of existing electrical infrastructure and impacts for each of the recommended decarbonization scenarios when considering forecast future electrical demand. The electrical team accompanied the sustainability team to site to review the building’s electrical infrastructure to review and assess its current condition and then worked with the team to understand the scenarios being considered and input on electrical infrastructure impacts.

AECOM will deliver meeting minutes. The City will have three (3) business days to provide comments to the draft minutes. If no comments are received, AECOM will assume the City’s agreement with the minutes and issue final minutes. • Scope includes a one-day site visit and an allowance for virtual coordination meetings. The City will provide AECOM with full access to the building and site and will provide a City employee to escort the AECOM team during the survey. Our site visit will be non-intrusive, meaning we will take photos, note existing conditions, verify portions of the as-built drawings, note locations of equipment, and take measurements as necessary for the scope of work. We will not open equipment, other than hinged doors on panelboards or equipment that does not expose dead fronts, nor will we test functionality of devices, such as breakers, lighting controls, or switches. • The project kick-off meeting can be hybrid or virtual. • The City will provide a single set of consolidated and deconflicted comments to all draft and pre-final deliverables within 14 calendar days of receipt or as required for the project schedule/ project deadlines, as agreed with the City. • Comments received on draft report sections will be incorporated into the proceeding Sustainability Report Draft. • One round of City review has been assumed for the Full Sustainability Report. • Deliverables will be provided in electronic PDF format. • The City will provide available utility metering data and as-built or as-constructed drawings to AECOM for our use. AECOM will not provide metering of any electrical equipment. As-builts/as-constructed drawings will be provided in PDF, as well as CAD, if available. When information is not available, assumptions agreed upon between the City and AECOM will be used . AECOM will not revise as-built drawings to incorporate findings. The City will provide current lighting control time clock and sensor setpoints to AECOM. Our analysis of the existing lighting and lighting controls system will use these in determining improvements and upgrades. • Scope assumes the City will define the quantity of fleet and public EVCS desired. • Analysis of ADA compliance is limited to the analysis of Accessible EVCS and their access as required by CalGreen and California Building Code. We will use as-built topographic data for slope analysis or take measurements in field as necessary if as-builts are not available. • AECOM’s findings represent its professional judgment. Neither AECOM nor its parent corporations, nor their respective affiliates or subsidiaries (“AECOM Entities”) make any warranty or guarantee, expressed or implied, with respect to any information or methods contained in or used to produce the Deliverables. • Any delay in data or comment delivery to AECOM by the City team may result in an extension to the schedule. Unreasonable extensions to the schedule caused by client actions may result in additional fees. • The rate sheet provided is valid through the initial terms of the Agreement. Thereafter, the rates may be adjusted upon mutual agreement between the parties. • Any capital cost estimates undertaken in this base line effort will be rough order of magnitude (ROM) appropriate for strategic planning/concept screening and equivalent to AACE Class 5 estimates. 29AECOM 04 Schedule 30 Prepared for: City of Diamond Bar Schedule TASKS Jun-25Jul-25Aug-25Sep-25Oct-25Nov-25Dec-25Jan-26Task 1 Kickoff & Ongoing Project Management 1.1 Kickoff Meeting 1.2 Ongoing Project Management Task 1 Electrical Infrastructure Evaluation 1.a Assess Electrical Infrastructure 1.b Evaluate Electrical System Compliance 1.c Evaluate Existing Lighting Controls 1.d Review As-Builts Task 2 Project Future Demand 2.a.i Electrification of Fleet 2.a.ii Installation of Fleet & Public EVCS 2.a.iii Future Expansion 2.a.iv Future Solar and BESS Task 3 EV Charging Infrastructure 3.a Identify Feasible EVCS Locations 3.b Determine Impact to Existing Parking 3.c Evaluate ADA Compliance Task 4 Sustainability Enhancements Analysis 4.a.i Carport Solar 4.a.ii BESS Peak Shaving and Backup 4.a.iii Resilience and Reduced Operational Cost 4.a.iv Improvements to Generator Task 5 Infrastructure Recommendations 5.a Identify Upgrades and Improvements 5.b Recommend Phasing Strategy Task 6 Conceptual Plan and Deliverables 6.a Sustainability Report 6.b Conceptual Site Plans Optional Tasks A.
