The Union Park site is situated on expansive clay soils known to experience seasonal shrink-swell movement. Foundation design required careful consideration of soil conditions to minimize differential settlement, with engineered fill specifications and moisture barrier requirements incorporated into the foundation package.

Saskatchewan's design snow load of 1.9 kPa governed many roof framing members and required careful attention to drift accumulation at lower roof sections adjacent to higher building elements. Roof framing layouts were adjusted to manage snow drift loads without exceeding allowable member sizes.
