GUELPH, ONTARIO, December 20, 2011 - Armtec Infrastructure Inc. ("Armtec") (TSX: ARF and ARF.DB) today announced it has secured a number of rail infrastructure projects, valued at over $30 million, within the Greater Toronto Area. These projects were anticipated as part of the previously announced $50 million in new contracts that are expected to be booked during the fourth quarter. The awarded projects include the design and manufacture of infrastructure products for the West Toronto Diamond rail-to-rail grade separation and two parking garages supporting the GO Transit network. A division of Metrolinx, GO transit is the regional public transit service for the Greater Toronto and Hamilton area for approximately 57 million passengers a year. Metrolinx is an agency of the Government of Ontario and was created to improve the coordination of transportation in the Greater Toronto and Hamilton areas.

For the West Toronto Diamond project, Armtec has been subcontracted to supply Flexwall® architectural panels and bridge girders. When completed, there will be 10,200 square metres of Flexwall insulated precast wall panels and 100 precast bridge girders. The Flexwall panels will serve as an aesthetic treatment to partially line the rail corridor. The project is scheduled to get underway in 2012.

In addition, Armtec is starting work to design and manufacture two parking structures totalling 80,000 square metres for GO Transit's Oakville and Ajax stations. Armtec will design and supply all the components, including double tees, beams, spandrels, columns, shear walls, column walls and exterior architectural wall panels. The Oakville garage is set for completion during the summer of 2012 and Ajax is estimated to be finished by the end of the same year. Both projects are scheduled to commence production immediately, and once completed, the two transit stations will supply a combined total of 2,776 new parking spaces for GO Transit customers.

"We are very pleased to have been selected for these important rail infrastructure contracts within the Greater Toronto Area. These projects fit extremely well into the core competencies of our Engineered Solutions business," said Mark Anderson, President and Chief Executive Officer. "Also, we are excited by the opportunity to capitalize on our strengths and expertise and showcase the innovative design and capabilities of our products and services."
