The IHS Whiteriver Hospital Replacement Project is a major federal healthcare infrastructure investment serving the White Mountain Apache Tribe and surrounding Native American communities on the Fort Apache Indian Reservation in eastern Arizona. The project replaces the aging 1979 Whiteriver Indian Hospital, expanding healthcare capacity and modernizing medical services for a rapidly growing regional population. The new hospital campus is designed to serve a projected primary service population of approximately 19,000 residents by 2030, significantly improving access to comprehensive medical care in a remote rural region. Once complete, the Whiteriver Hospital replacement will become one of the largest healthcare facilities on the Fort Apache Indian Reservation, expanding access to modern medical services for thousands of tribal members and surrounding rural communities. The new campus will significantly enhance healthcare capacity, reduce reliance on distant regional hospitals for specialized care, and strengthen the long-term healthcare infrastructure serving the White Mountain Apache Tribe.
The project consists of a ~400,000-square-foot replacement hospital constructed on the existing 14-acre campus while maintaining continuous medical operations during development. The new facility will provide a full range of healthcare services including inpatient and outpatient care, emergency services, ambulatory surgery, dental services, behavioral health, specialty clinics, diagnostic imaging, and rehabilitation services. The program also expands clinical capabilities with new services such as in-patient surgery, transitional care, mammography, occupational therapy, speech therapy, and comprehensive pain management.
Designed by SmithGroup, the facility incorporates advanced healthcare infrastructure, modern clinical environments, and culturally informed architectural design developed in collaboration with the White Mountain Apache Tribe. The project integrates daylighting strategies, natural materials, and outdoor healing spaces reflective of Apache traditions while targeting LEED Gold certification through high-performance building systems and energy-efficient mechanical infrastructure.
The overall program schedule includes approximately 18 months of design development, a 9-month procurement phase, and an estimated 36-month construction period, reflecting the complexity of constructing a major healthcare campus on an active hospital site while maintaining uninterrupted patient services.
APR provided independent mechanical cost estimating services supporting SmithGroup and the Indian Health Service throughout the planning and design development process.
APR’s mechanical estimating lead developed detailed cost models for the hospital’s complex mechanical infrastructure, including central plant systems, air handling units, hydronic distribution networks, specialty ventilation systems for surgical and clinical environments, and mechanical systems supporting inpatient and outpatient medical operations. These analyses incorporated disciplined quantity takeoffs, equipment pricing, constructability considerations, and lifecycle cost comparisons to support informed system selection.
Working closely with SmithGroup’s architectural and engineering teams and Indian Health Service stakeholders, APR evaluated multiple HVAC and central plant system configurations, comparing first-cost and long-term operational performance to ensure that system selections supported both sustainability objectives and program budget constraints. The team incorporated detailed quantity takeoffs, equipment pricing, constructability considerations, and life-cycle cost perspectives to ensure that system selections balanced performance, maintainability, and cost efficiency.
APR’s work also addressed the logistical and infrastructure challenges associated with constructing a major medical facility on an active hospital campus, helping the project team evaluate phasing strategies, utility tie-ins, and mechanical system transitions required to maintain continuous healthcare operations during construction.
- Developed cost estimates supporting planning and design activities for a major replacement hospital program
- Supported evaluation of cost impacts associated with clinical, support, and infrastructure components of the new facility
- Provided various what-if models based on potential equipment costs to assist in determining final fit-out selection
- Develop reliable cost baselines for complex hospital mechanical systems
- Evaluate multiple HVAC and central plant strategies
- Maintain budget alignment as the design progressed
- Integrate LEED Gold sustainability goals into system selection
- Address constructability and phasing challenges associated with building on an active healthcare campus
- Applied benchmarking from comparable healthcare and institutional projects
- Provided cost intelligence to support design development and budget alignment
- Contributed estimating expertise for a large, multi-phase healthcare project in an active service environment
