American Samoa

Based in the desert southwest, GLHN has delivered successful architectural and engineering solutions to healthcare clients from coast-to-coast and in locations as geographically and environmentally diverse as American Samoa, Hawaii, and Alaska.

American Samoa Coastline

American Samoa is about half way between Hawaii and New Zealand, in the heart of Polynesia, right on the edge of the International Date Line. The five volcanic islands that comprise American Samoa have a total land area of 76 square miles. The tropical climate averages 128 inches of rainfall annually in the dry parts of the island, and over 200 inches in the wetter areas. HVAC design conditions are 90F DB and 80F WB.

The Lyndon Baines Johnson Tropical Medical Center (LBJ) in Pago Pago is the only tertiary, acute care facility on the island. Completed in 1968, LBJ serves the entire population, providing care in the 150 bed Medical Center and supporting outlying public health clinics and dispensaries.

LBJ Building

In 2012, GLHN sent an integrated team of architects and engineers 5,085 miles to American Samoa, initiating a series of phased renovation and expansion projects at the LBJ Medical Center. With a combined scope of over $25 million, the projects affect improvements to approximately 17,000 square feet in departments as diverse as Hemodialysis, Surgery, Labor-Delivery-Recovery and Nursery, Respiratory Therapy, and Forensic Psychology. These projects will enable the continued success of LBJ in serving the growing needs in America Samoa.

The Surgical Suite project includes general operating rooms, specialty procedure rooms, and support spaces. Another phase addresses upgrades for LDR rooms, a cesarean delivery room, newborn holding, and Level II and III (NICU) nurseries. In addition to the usual challenges faced in creating and maintaining environmental conditions for operating and procedure spaces, GLHN considered design parameters unique to the remote location and tropical humidity. For example, 44 gallons of moisture will be extracted every hour while conditioning the air destined for the operating suites. Building envelope systems and drainage are designed to handle a rainfall over 10 times that experienced in Tucson. The building shell must also resist cyclone wind speeds in excess of 140 mph, and seismic forces similar to Los Angeles, CA.

As seen in this image, GLHN made extensive use of Revit® 3D modeling to integrate the myriad of mechanical and electrical systems necessary to support the healthcare functions. Please click on the image below to download the 3D PDF file. File best viewed with Adobe Acrobat Reader.
