The main scope of work for this project was to convert an existing warehouse building into a state-of-the-art soy sauce manufacturing facility. In addition to this building, Lee Kum Kee (USA) Foods, Inc also operates from the building to the east of this facility. This project consisted of redesigning the Office Block from one story to two stories implementing "feng shui". The remaining building was designed for warehousing and production areas. Pettit also designed the Utilities/Services area, which was located outside, north of the building. The total area of tenant improvement was approximately 60,100 square feet. Pettit handled all aspects of the project from start up design, construction documents, permitting process, construction management to project close-out.

The total Design/Build cost was approximately $4.5 million.

Pettit's largest design/build project to date is this $200 million facility. The initial phase of the world's largest cheese / whey / alcohol plant was completed on time and under budget. Pettit has since been retained as the plant's sole Architect and Engineer for over 21 years. Services provided have included architecture, civil, structural, mechanical, electrical, geotechnical, and fire engineering, process piping, programming, landscaping, SCADA design, cost estimating, construction support and value engineering.

Pettit has been a Lead Professional Consultant for Dart for more than 14 years, and has completed a variety of Design/Engineering and Design/Build projects.

​Pettit designed a new two-story 240,000 SF warehouse with a main floor and lower storage/shipping level. There was an added degree of significant earthwork due to the lower storage/shipping level, so Pettit designed a 1,200 FT long, 10 FT high retaining wall to recapture a valuable one-half acre on an already 90% utilized site. The civil engineering covered approximately eighteen acres, and included rough and precise grading, underground utilities, horizontal control, parking layout and striping, erosion control plans, and a hydrology analysis.



This $8 million, 40,000 SF facility went through a conversion from a meat plant to an egg processing plant. Our design included modifications to the existing building and the addition of several new areas. Pettit was involved in the project from the early stage of conceptual design through the construction phase and construction management process. The project required Pettit's in-house, multi-discipline effort and utilized the disciplines of Architecture, Civil, Structural, Building and Process Electrical, and Plumbing Engineering, as well as coordination with process, sprinkler, racking and refrigeration designers.
