We believe that the best value is derived from a building using durable materials that require low maintenance. Consequently, we typically avoid using wood framing, except in renovation work; we prefer steel and concrete masonry as our primary structural materials. We fully expect our buildings to last 80-100 years, based on the European model. High quality construction techniques derive from using high quality materials. For example, all of the exterior ﬂashing and sheet metal at the Coronado Animal Care Facility is copper, because the building is sited next to the bay; this material will be durable and long-lasting in that environment without maintenance. Our core values are based upon respect for the communities in which we work, along with trusteeship of our environment.
