Commitments and contingencies: (a) The REIT is currently constructing a two million square foot office building in Calgary, Alberta (the “Bow”), which is fully  pre-leased to EnCana Corporation for a 25-year term. The REIT has committed to incurring additional construction and  development costs for this project of approximately $397,000, including capitalized interest, over the remaining  construction period, of which approximately $360,000 is expected to be incurred during the next twelve months. As at  December 31, 2010, the total cost incurred on the project amounted to $1,150,094 (note 4) (2009 - $719,173). This  budget includes the construction of 1,360 parking stalls. Construction commenced in the spring of 2007 and is planned  to be completed in 2012 to meet the completion timetable. The first four tranche completion dates upon which floors are  scheduled to be delivered to EnCana Corporation are as follows: floors 1-14 by July 3, 2011, floors 15-24 by August 29,  2011 and floors 25-42 by October 12, 2011. The delivery schedule of floors 43-59 is expected to be set by the end of  March 2011. In certain circumstances, should the delivery of tranches of space within the project be delayed, the REIT  will be liable to the tenant for certain delay costs in the form of free rent, which may be significant.  39
