LAFAYETTE — Renovations and new construction to transform a former middle school into a specialized career and technical high school campus could be complete by fall 2013 at an estimated cost of $21 million, designers told the School Board on Wednesday.

Designers presented the board with space requirements needed for the specialized, industry-based certification programs planned for David Thibodaux Career and Technical High School during a workshop Wednesday.

Nearly 83,000 square feet of additional space will be needed to provide some of the specialized instruction, according to figures presented by the design team led by Architects Southwest.

Construction will need to be staged around the students, who will occupy the former N.P. Moss Middle School site starting in August, project manager Wayne Domingue of Architects Southwest said.

The district’s newest high school began at a temporary location on the campus of Acadiana Technical College last year. It offers students an opportunity to earn industry-based certification and college credit in tandem with a high school diploma.

For the past few weeks, designers have met with teachers, staff and community to determine facility needs.

“They felt it very important that the school should fit the program” rather than the programs be designed to fit the existing space, Domingue said.

Examples of some programs to be offered at the school include: fashion, photography, drafting, culinary arts, hotel administration, business, cosmetology and barbering, early childhood education, construction, welding, auto mechanics, and certified nursing assistant.

The stakeholder feedback helped shape an education program for the site — which details the types and size of space needed and recommendations for the locations of programs.

Programs such as culinary arts, cosmetology and early childhood may be located near school entry points so the public can more easily access the services the students provide as part of their training, said Curt Carlson, an architect with SHArchitecture of Las Vegas and project consultant.

Some programs also offer opportunities for shared lab and workspace, he added.

A mock hotel room for hospitality management could double as a patient room for the health programs, he noted.

The completion of the education program is only the first phase of the design process, Domingue said.

The design team next moves into development of a schematic design followed by more-detailed design. Once a design is OK’d, construction documents will be developed and the bidding begins.

The design team also includes DLR Group of Kansas City.
