PREFACE: It is not intended that the Contractor's contractual and state any way relieved or foregone by the presence of the Special Inspector. The Contractor has the sole responsibility for any deviations from the Contract Documents. The Special Inspector does not replace the duties or the quality control personnel of the Contractor. The Special Inspector shall not have control or charge of, and shall not be responsible for, construction means, methods, techniques, sequences or procedures, or safety precautions. B. OBLIGATIONS OF THE SPECIAL INSPECTOR: The Special Inspector is responsible to both the owner and the governmental agency having jurisdiction over the project for observing that the work is executed in accordance with the Contract Documents. It is the obligation of the Special Inspector to notify the Contractor, governmental agency having jurisdiction over the project, Architect/Engineer of Record, and the Owner of the following: 1. The use of materials, equipment, and/or workmanship that do not conform to the Contract Documents or that will cause improper construction. 2. Any work which is not being performed by the Contractor in accordance with the approved Contract Documents. 3. The recommended removal or repair of faulty construction, or of construction performed without inspection and not capable of being inspected or tested in -place. 4. The request for interpretations from the Architect/Engineer of Record. C. REPORTING INFORMATION AND OBSERVATIONS: The Special Inspector's reports are a follow- up to actual observations during construction; however, they are of extreme importance in that they enable the governmental agency having jurisdiction over the project, the Owner and the Architect/Engineer of Record to keep current with the work, while it is in -progress and will be of value in case of changes in the structure or its use in the future. The report shall consist of one or all of the following entities: 1. Record of progress. 2. Observations given to the Contractor. 3. Deviations from the Contract Documents with reasons and problems encountered, with recommendations for the Contractor to initiate proposed solutions or requests for information from the Architect/Engineer. 4. Log of area inspected. 5. Special Records (foundation preparation and concrete tests) from the testing agency. 6. Record of placing concrete. PY 7. Reports of Engineering Testing Laboratory inspe ins, alu tiocd t 8. Pertinent photographs, where needed. [� `" /// Pagel 0 4� The Special Inspector shall keep a log, with the reports to the Owner based on the above items. Reports shall be filed under seal to the Building Department. D. REQUIRED INSPECTIONS Unless specifically stated otherwise by the Engineer of Record, the following list of minimum inspections shall be performed by the Special Inspector or his/her authorized representative: 1.) Pre -excavation inspection of concrete spalling and marking of areas for excavation 2.) Preliminary excavation inspection to locate affected Post Tensioned (PT) cables. 3.)
