NATIONAL CEMETERY ADMINISTRATION IRRIGATION SITE VISIT SUMMARY. Site Visit Conducted and Summary Prepared By Andy Slack, NCA National Irrigation Engineer Site Visit Conducted and Summary Prepared By Andy Slack, NCA National Irrigation Engineer. I attended the initial irrigation pre-construction meeting for the irrigation installation in April and was very impressed with the knowledge and personnel of the irrigation subcontractor for the job – Commercial Irrigation & Turf (CIT) out of Peoria, Illinois. Both the company, and the Irrigation Manager, Jim Cassidy, have a lot of experience in large turf/golf course type irrigation installation based on their web site and on references from the irrigation industry I checked with throughout the Midwest. The pictures and descriptions of the work being performed by CIT that have been sent each week from Jacobs Engineering have been evidence of good quality work.
