AAES provided engineering and consulting services for many clients to include NASA, US Air-force, Bechtel, City and County of San Francisco, Pacific Gas and Electric (PG&E), Sacramento Municipal Utility (SMUD), Sothern California Edison (SCE), San Diego Gas and Electric, Jones Lang LaSalle, VA Hospitals, Bank of America and Chevron.
1. PUC CIP Procedures Activities
Provide consultant services in the development and finalization of PUC Infrastructure CIP procedures including, but not limited to:
1) Startup, Testing and Training,
2) Startup Test Content,
3) Operations & Maintenance Manual and
4) Warranties procedures.
Work included working sessions with Operations, Engineering Design Bureau (EDB) and Construction Management Bureau (CMB) staff, and field inspections of existing facilities.
2. Training Activities
Provide City training of designers for development of electrical and instrumentation & control (I&C) plans and specifications including process & instrumentation diagrams (P&IDs). Participants included Electrical Engineering and Mechanical Engineering Sections of EDB, Electrical Engineering and Mechanical Engineering Sections of DPW/Bureau of Engineering.
Provide City staff training of construction management and operations personnel on inspection of electrical and mechanical work with emphasis on equipment and piping/conduit equipment layouts, and mechanical, HVAC, electrical and I&C plans, specifications and lists. Participants included staff from Project Management Bureau (PMB), CMB, Operations and DPW/Bureau of Construction Management.
3. Construction Management Activities
Provide mechanical and electrical inspection services for all PUC projects. AAES Engineers also provided hand on training to the City Inspectors on these projects.
4. As-Needed Support Activities
Provide support for procedures development, training, reviews and comments on project documents for mechanical, electrical and instrumentation & control plans, specifications, cost estimates, startup test plans and other related items.
AAES created for each SFPUC Facility O&MI Manual. This manual becomes a living document controlled by the Facility Operations Division Manager. The AAES tasks included:
AAES trained the SFPUC Design Staff on the following Subjects:
AAES Created Project Manual to be utilized by the SFPUC Project Managers which included:
AAES Engineers visited each site, identify existing distribution panels, create or revise existing panel schedule (drawings) to comply with Code. This process includes identifying each breakers and its associated load. The results improved safety to personnel, equipment and to the public.
1. Replace existing 4KV Utility Feeder with 12 KV primary service from PG&E. This included the sizing and specifying 12KV Station Transformer and 12 KV service entrance and to be housed in the new 12KV switchgear.
2. Remove and replace four medium voltage motor starters with four medium voltage circuit breakers to feed the (E) VFD's that control the (E) motors. Remove (E) controls to (E) starters.
3. Replaced (E) WPII motors with dry pit submersible motors. Modified wiring as needed.
4. Modified (E) VFD's control wiring to control new motors.
5. Replaced two existing 120/240 volt fused and light distribution panels in control room.
6. Replaced the UPS in the battery room and resolved battery room code issues.
7. Remove and replace the dual 480 volt load center distribution sections.
8. Replaced (E) MCCs and prepare plans to direct the contractor to remove wiring and surface conduits to abandoned equipment.
9. Removed and replaced (E) luminaries.
10. Provided HMI station by connecting (E) Quantum PLC to existing server at Northpoint via switches and new T1 line. Northpoint server's monitors Channel Pump Station processes and provide Wonderware graphics back to Channel PS screen.
11. Survey the (E) Central Control Room Panel and prepare plans to direct the contractor to remove indicator lights and push buttons for abandoned equipment along with associated conduit and wiring. Some indicator lights are relocated to the Main Station Control Panel, and the (E) Central Control Room Panel was removed.
12. Provided Main Station Control Panel clean up by deleting alarm annunciator panel, tracing and removing wiring from/to (E) abandoned equipment and (E) abandoned equipment MCC bucket.
13. All of the above work was done while the station remain on line. AAES accomplish this by renting 12KV Switchgear, Emergency Generators, Step Down Transformers and sectionalize the work without any impact on station operations.
AAES portion of the project is to engineer and design the Electrical & Controls, size and specify equipment, assist in startup and training. The scope included three-way solenoid valve controlled by the vaporizer switching timer, vortex flow meter w/indicator, solar panels, battery, inverter, lighting, and grounding. The project also included EPC design of the security system.
AAES provided the owner's engineers review tasks from start to finish. This included review all calculations, drawings and equipment specifications.
