G.S. Wark performed the CL3 construction work at McMaster University to the satisfaction of Merrick Canada and the Public Health Agency of Canada testing criteria that achieved successful certification. I would recommend G.S. Wark to the other possible clients for comparable CL# work. I am in the process of designing a National Biocontainment Laboratory in New Zealand where their construction community is not as knowledgeable nor capable and I wish I could export the G.S. Wark team to do the work!
