Project Description:
This project involved the construction of a two storey below grade structure adjacent to and in part below the Centre Block on Parliament Hill in Ottawa.  A significant challenge to the project was the completion of the massive rock removal to the heritage structure during the summer recess.  The structure consists of a heavily reinforced concrete frame which will house the new electrical distribution for Parliament Hill, communication centres, workshops and storage spaces.

This project had very sensitive historical considerations.  Careful mapping of each stone was required.  Boring of ten feet diameter tunnel through the rock under the building and the blasting adjacent to the building required detailed sophisticated monitoring.  There was a heavy involvement with heritage groups.

The project was formally partnered with great success.
