Department of General Services | Exposition Park Underground Parking Structure, Headquarters and Community Center, and Park (EPUHC)

Owner: Department of General Services
Period: 2024 – Present

The objective of this project is to develop performance design criteria to facilitate a Design-Build Entity in developing and delivering a new underground parking structure, surface parling areas, roadways, headquarters and community center building, infrastructure, and park for the office of Exposition Park Management.   

 

This project involves the demolition of existing parking lots, installation of underground utilities, and construction of a new 720,000 sqft parking garage. It will also construct an approximate 43,000 sqft Exposition Park Headquarters and Community Center with an emergency power system, a 120-space bus parking lot covered by shade structures with photo voltaic system. The project will be designed and constructed to obtain at a minimum LEED Gold certification and Zero Net Energy (ZNE). 

Kewo Engineering provides professional engineering and management services as the Criteria Architect/Engineer for the Exposition Park Underground Parking Structure, Headquarters and Community Center, and Park (EPUHC). Our services include the following:  

• Electrical Engineering 
  • Review available existing designs/drawings/documents of electrical infrastructure for the project site and in-scope facilities.  
  • Review preliminary estimate of electrical loads, including DC Fast Chargers for Buses and Level 2 EV Chargers 
  • Determine preliminary equipment layout, single line diagrams, and load schedule for LADWP electrical equipment and customer-owned electrical equipment 
  • Develop electrical design criteria for LADWP and customer-owned electrical equipment for inclusion in RFP documents.  

• Project Management, Engineering Support & Coordination 
  • Assess existing condition of electrical service and loads including lighting, EV charging stations, and others impacted by parking lot relocation 
  • Coordinate with LADWP to procure new electric service and associated new Industrial Station.  
  • Identify potential locations and required areas for Industrial Station, meters, and switchgear.  
  • Engineering support during RFP and bidding stages

Owner: Los Angeles World Airports / Los Angles Department of Water and Power
Period: 2019 – 2024

The RS-X project uses a two-phase design/build delivery method to design and construct a new 320MVA 230kV/34.5kV substation and its associated 230kV and 34.5kV ductbanks to provide dedicated power to LAX airport. RS-X is LADWP’s first Receiving Station built over three decades and includes a 230kV Switchyard, 34.5kV switchyard, and control house. 

For this project, Kewo Engineering provided electrical engineering design and construction administration support for the following primary scopes of work: 

• (4) 230kV Underground Ductbanks; 
• 320MVA Receiving Station, including 230kV switchyard, 34.5kV switchyard and control room; and 
• 34.5kV Underground Circuits within substation. 

 We developed electrical designs and specifications at various stages (30%, 60%, 90%, and 100%) and provided engineering support during construction. We performed various analysis and studies, including grounding, lighting/photometrics, and AC/DC load. 

The substation design  is for infrastructure at a 63,000sqft facility to accommodate high-voltage electrical equipment (transformers, circuit breakers, CVT’s, disconnects, etc.), lighting, and associated control room. 

 The 230kV ductbank design involves (4) new 230kV circuits by intercepting two (2) existing 230kV circuits between Scattergood Generating Station and Receiving Station K. Intercepting these circuits provides the substation with two primary sources of power: Scattergood Generating Station and RS-K.
