Box 71095 Eugene, OR 97401 Re: ;3516 Ambleside Drive. Sorirndield Job #01076 As you requested, an inspections of the Post-Tensioned slab installation were performed at the above noted location. During those inspections the following observations were made. An inspection of the tendon layout was performe<i on Aprilll, 2001. A total of 15 tendons had been installed, with a total length of 417 feet as per tendon placement plan. The tendons were installed by Post Tension of Oregon. All tendons were installed according to allowable tolerances noted on the plans to pass around plumbing and electrical stub outs required in the slab. , An inspection of the tendon tensioning was performed on April 18, 2001, after the concrete had reached the required 2000 psi for tensioning. The tendons were stressed to ajacking force of33 kips, with a pump gauge reading of5500 psi. See attached monostrand tendon stressing record provided by Post Tension of Oregon dated 4/18/01 for measured tendon elongations. The serial number of the jack used for stressing is # 1 028, and the gauge is #PTO 1. The tendon mill test certificate #V3238 shows that the tendons have a modulus of elasticity of28800 ksi. The calculated and measured elongation for all of the installed tendons was within the acceptable deviation range of + or - 10%. The installed and elongated tendons meet the calculated design requirements of the post-tension slab and the tendon ends may be cut. Thank you for this opportunity to be of service.
