Geotechnical & Engineering Services for Lafayette and West Central Indiana.

Subsurface investigations, soil borings, foundation design recommendations, and geotechnical reports. West Central Indiana's Tipton Till Plain, the outwash and alluvial sequences along the Wabash River corridor, and the variable bedrock depth across the region are familiar territory for our engineers. From Purdue's Discovery Park District to industrial sites along I-65, we know what's below before we drill.

SK hynix & Semiconductor Investment

SK hynix's $3.87 billion advanced HBM packaging fab north of Kalberer Road in West Lafayette — supported by up to $458 million in CHIPS Act funding — is the largest single private investment in Indiana's history and one of the most technically demanding projects in the state's construction pipeline (NIST). Semiconductor facilities demand an uncompromising standard of geotechnical investigation, vibration analysis, precise foundation tolerances, and construction testing that scales with an accelerated buildout. Alt & Witzig has the depth, credentials, and regional proximity to serve this class of work.

Purdue University & Discovery Park District

The Purdue Board of Trustees' 10-year capital plan, approved in August 2026, extends a sustained wave of investment across the West Lafayette campus — from the Daniels School of Business project and the Nursing and Pharmacy Education Building to the potential first major renovation of the Potter Engineering Center since it opened. At Discovery Park District, Saab's aerospace manufacturing facility set the tone for advanced-manufacturing tenants. These are projects where engineering depth, inspection discipline, and reporting rigor are non-negotiable.

Healthcare Expansion — Two Systems, Multiple Campuses

IU Health's $214 million Greater Lafayette Community Growth Project includes a new hospital in West Lafayette and a state-of-the-art Cancer Center on the IU Health Arnett campus (IU Health). Franciscan Health is expanding on the West Side with a comprehensive orthopedic center and a 24/7 freestanding emergency department opening in spring 2027 (Greater Lafayette). Parkview Health has also announced a fourth hospital plan along Endeavor Drive, with construction expected to start in 2026 (Based in Lafayette). Healthcare construction demands the precision, credentials, and staffing depth Alt & Witzig has built its reputation on.

Subaru of Indiana Automotive & Industrial Growth

SIA's Lafayette assembly plant — one of Indiana's largest manufacturing employers — continues to invest in the facility, including a $158 million diversification project and a $64.5 million hybrid production expansion, both requiring comprehensive geotechnical programs and construction testing at industrial scale. The broader I-65 corridor through Tippecanoe County continues to attract industrial, warehousing, and logistics investment served daily by our Lafayette team.

Downtown Lafayette & West Lafayette Mixed-Use

The 147-unit Lafayette Riverfront mixed-use apartment building along North 2nd Street and the continued redevelopment of Wabash Landing on the West Lafayette Levee represent a downtown mixed-use pipeline finally beginning to match the region's demand. Adaptive reuse, mixed-use infill, and multi-phase development programs require the kind of coordinated engineering scope — Phase I ESAs, geotechnical investigation, and construction testing under one project manager — that Alt & Witzig delivers as a matter of course.

Regional Institutional & K-12 Construction

Tippecanoe County's population growth, Purdue's continued enrollment strength, and school-district capital programs across West Central Indiana are driving sustained institutional construction — from K-12 additions and renovations in Tippecanoe School Corporation and Lafayette School Corporation to municipal and county-level infrastructure projects. Institutional clients demand precise engineering, strict compliance, and reporting discipline. That's exactly what Alt & Witzig has built its regional practice around.
