Kaiser Permanente

various locations statewide, HAWAII

Some of our featured projects with Kaiser Permanente include the following:

Kaiser Regional UPS Upgrades, Various Locations Statewide, Hawaii

Our firm provided the mechanical, electrical, and fire protection engineering design work to evaluate and upgrade the UPS systems at a total of eight (8) facilities on Oahu, Maui and the Island of Hawaii. Kaiser and the AE team visited all listed facilities to determine UPS requirements for their replacements. The eight facilities include: Moanalua Medical Center, Dole Cannery, Mapunapuna, Ala Moana, Waipio and Ko’olau (Oahu); Maui Lani Elua Clinic (Maui); and Kailua-Kona Medical Office (Hawaii). Our scope of work included determining electrical and mechanical requirements for power and AC systems for consolidating UPS equipment, providing new UPS, lighting inverters, panelboards, electrical distribution systems, and modifications of ductwork.

Kaiser Moanalua Renovation & Expansion, Honolulu, Hawaii -

This facility was constructed in several phases from 1982 to 1984, consiting of 3 primary wings: a 4 level, 58,200 sf nursing wing, a 4 level 107,028 sf clinic wing with a lower level basement, and a 214,523 sf  5 level ancillary services building.  The total current gross floor area of the complex is approximately 379,751 sf.  In 2003, we prepared a study to assess the condition and capacities of the existing mechanical and electrical system infrastructure, and developed a mechanical and electrical master plan to accommodate the addition of a new 5 level, 139,800 SF tower, renovation of approximately 83,600 SF of the existing hospital, and renovations and upgrades to the central plant. Our specific scope of work for this project included assessment of the HVAC, plumbing, electrical, fire alarm, fire sprinkler, medical gas and med gas alarm, emergency power, LAN and telecom systems for current and anticipated upgrades. Our study also provided recommendations for the existing hospital to comply with current JCAHO guidelines and to improve operations and energy efficiency. Our scope of work included plumbing and medical gas systems, new central chilled water AHU, new ventilation exhaust systems, fire sprinkler expansion systems, central plant improvements, lighting, emergency power distribution and new emergency generator system. Estimated Cost: $29 million.

Kaiser Mapunapuna HVAC System Master Plan Study, Honolulu Hawaii

Kaiser wanted to look at the overall Mapunapuna Clinic facility and inspect all HVAC equipment from AHUs down to air distribution and controls. Known issues included lack of controls, cold and warm zones that developed seasonally, and aging equipment that may have been nearing the end of service life. Their goal was to have a long-range plan for the HVAC system serving their Mapunapuna Clinic facility to follow. We conducted field surveys and discussions with facility engineering support services and reviewed an existing test and balance report as part of our assessment. We documented system configuration, condition, and the issues that were identified. We formulated and summarized our immediate and long-term recommendations for mechanical and electrical upgrades, including a cost estimate, in pre-final and final reports.

Kahauiki Village

Kahauiki Village provides long term, affordable residences for homeless families. Modeled after Hawaii’s plantation era culture, Kahauiki Village’s vision is to break the cycle of homelessness by embracing:

• A Public-private partnership to finance, construct, and support the families with on-site social agency and child-care facilities, and commitments from neighboring businesses to hire village residents.

• A 144-family master planned community built on an underutilized 11.3 acre parcel with the following features:

  • Re-use of homes were originally built for the Tohoku, Japan tsunami victims

  • Community support buildings

  • Garden areas, fish farms, and recreational areas

• Low-cost, maintainable, and sustainable construction solutions.

InSynergy Engineering, Inc. in collaboration with PhotonWorks, engineered an integrated off-grid renewable energy micro-grid that includes:

• the first application of a solar-powered microgrid to an entire residential community in Hawaii,

• first of its kind shared photovoltaic (PV) system with battery energy storage,

• gas for cooking, backup water heating and power generation,

• a grid electricity tie for the battery trickle charging.

The integrated microgrid system design includes full mechanical, plumbing and electrical systems, as well as 1956 kw of PV, a 1.965 MWH BESS, and a 300 kw standby LPG generator. Completed in 2018, this innovative projects includes the implementation of a reliable and failsafe microgrid control system that accommodates all potential modes of operation due to a lack of proven off-the-shelf solutions. In addition, it utilizes larger, lower cost inverters that serve multiple housing units and distributed sewer lift stations, and uses three-phased balanced power distribution within housing units.

This project was awarded a 2019 ACECH Engineering Excellence Design Award.

The Queen's Medical Center

HONOLULU, HAWAII

In order to accommodate the growing need for emergency healthcare services, the Queen’s Medical Center took action by authorizing the design and construction of a new $10,000,000 emergency services ward.  The emergency services relocation involved renovating 25,000 sf of existing office space into an emergency ward which included fully equipped critical and trauma rooms, exam rooms, fast track triage area, a psychological disorder ward, dedicated infectious isolation rooms and waiting areas, and nursing stations.

As part of their ongoing facility improvement program, we recently designed the renovation of their entire chiller plant which included replacing two 1,000-ton chillers with two 1,350-ton high efficiency chillers, each equipped with VFD compressors.  A major system re-engineering was implemented to convert the old primary constant-flow chill water distribution loop to a new primary secondary variable flow chill water loop.  This conversion allowed the central plant to increase or decrease chill water flow based on actual cooling requirements.  These renovations resulted in an annual energy savings of $180,500.

Other renovation projects include:

• OR Upgrade and Renovation, Queen Emma Tower, 3rd Floor

• Replace Boiler Plant

• New Linear Accelerator

• Renovation of the air conditioning system for the main lobby

• Hot Water Study for POB 1, POB 2 & Central Plant

• Pauahi Tower Service Elevator Upgrade

• Renovation of Iolani 1 and Kinau 1

• Iolani 2 and 3 Renovation

• New MRI Unit Addition

• Diagnostics Lab, 4th Floor, Nalani Wing

• Grease Interceptor Study
