Rev. 1 Construction Specification for the Installation of Steel Poles Page 21 of 24 <br />Specification TLCS-1402 <br />in order to validate the established construction activity durations. If testing deviates from the results <br />in the initial testing, the construction durations should be updated accordingly, or more testing shall <br />be performed. <br />Special consideration should be given to establishing new construction durations, or performing additional <br />testing, when there are changes that may impact the trajectory of concrete curing. The factors include: <br />x Changes in the mix design or raw material sourcing. <br />x Changes in weather or seasonal variation, including temperature and precipitation. <br />x Changes in the local geology or soil conditions, including moisture content. <br />TECS-4001 Specification for Structural Concrete, section 1.0 provides the proper mix requirements <br />for the desired backfill. <br />Slump, air entrainment, and temperature testing shall be performed on the first truckload of each <br />day. The Constructor shall notify the Owner’s Representative immediately of any concrete that does <br />not meet the proper mix requirements. The tests shall be administered by the Constructor, and results <br />that fail to meet the Owners requirements shall be immediately reported. All other results shall be <br />communicated to the Owner’s Representative upon request. <br />Slump testing shall conform to ASTM C143, air entrainment testing to ASTM C231, and temperature <br />testing to ASTM C1064. <br />The Owner reserves the right to hire at its expense an independent testing agency to evaluate the quality <br />of the concrete provided. If this right is exercised, testing parameters will conform to TECS-4001, section <br />1.6.2.3. <br />Freshly placed concrete shall be protected from the loss of moisture for a minimum of seven days <br />or three days if high-early concrete is used. <br />Defects in formed concrete surfaces shall be repaired to the satisfaction of the Owner’s Representative <br />immediately after the forms have been removed. All honeycombing or large voids shall be removed <br />to sound concrete and replaced. Epoxy or latex bonding agents shall be used as a bonding medium <br />for repairs discovered and made after the concrete is seven days old. <br />11.0 Field Corrections <br />Any misfabrication of the steel structure that prevents proper assembly of members by the moderate <br />use of drift pins shall be immediately reported to the Owner’s Representative. No drilling, reaming, <br />welding, or other modification will be allowed without written authorization by the Owner. <br />If required, any welding shall be done by an AWS-certified welder only after approval by the Owner’s Engineer. <br />11.1 Field Drilling <br />Plug weld of misaligned holes shall not be permitted without written authorization by the Owner.
