Ken Hover’s two-part article (June and July issues) on what can be learned by carefully reviewing your concrete delivery tickets has generated a lot of interest. In an earlier blog, we asked about the use of electronic delivery tickets to replace the old paper versions—that also drew a lot of comments. Jay Shilstone noted that ASTM C09.40 subcommittee is looking for opinions and concerns about the use of electronic delivery tickets. Discussing electronic tickets, Jay wrote:
“A concrete delivery ticket is NOT just a receipt. It provides information that can be used to determine if the material delivered is within specification limits. Many of the items [on the ticket] relate to the specification limits. Now imagine if you had a Smart Delivery Ticket that could provide an alert if the concrete exceeded the maximum allowable age or slump or air content or total water or maximum water-cementitious ratio.
“If you are not on the jobsite when the concrete is delivered, a Smart Ticket could be emailed to you so that you could confirm compliance with the specifications as soon as the concrete is delivered. Not every job has a qualified concrete technician at the placement all the time.
“It is my opinion that an electronic delivery ticket could fulfill all the requirements of a printed one, and more besides.”
