The only significant deviation from approved plans consisted of heater remixing the travel lane adjacent to medians between Lance Drive and First Street and work as called for by Contract Change Orders. *There were two Contract Change Orders issued during the course of the work. These were necessary because of the fact that it was determined necessary to recompact the existing OSCD ~7 sewer trench prior to the heater remix and paving operation. This particular trench had been a continual problem for the City with frequent street failures occuring due to trench settlement. In 1972 and 1973, the City recompacted that portion of the trench between Lance Drive and First Street. The portion of the trench between First St. and Irvine Blvd. was not included in this project for recompaction because it was felt there had not been that much of a problem with it. However, just prior to the start of the work, a 115' long section of trench settled necessitating emergency street repairs. Subsequent investigation revealed that the entire trench between First St. and Irvine Blvd. had sub-standard compaction and for public safety reasons, it was decided to add this work to the project by Contract Change Order. These Change Orders are described as follows: CCO #1 - Provided for sawcutting and removing a 4.5' wide strip of pavement over the trench, removing the existing AB, jetting the trench, stomping the trench, and replacing the pavement with a 1.10' thick deep lift AC section. CCO #2 - Provided for compensating the Contractor for extra work involved during the trench recompaction work which was not anticipated. This work consisted in part of: (a) The existing AB was 2.0'± thick and had to be removed to permit penetration by the jet bar and more effective stomping. (b) During pavement removal, deep lift AC was encountered in several locations requiring special equipment to facilitate removal. (c) After jetting and stomping, the trench settled wider than the 4.5' width anticipated (in some locations up to 15' wide) requiring additional pavement removal and replacement. *See pages 9 & 10 -7- CONTRACTOR PERFORMANCE The Contractor's performance was excellent. The project was compacted one calendar day ahead of schedule. QUALITY OF WORK The City of Tustin is well satisfied with the quality of the work performed by the Contractor.
