ST. BARBARA CATHOLIC SCHOOL TASK 2 75-24272-01 <br />DIOCESE OF ORANGE SEPTEMBER 12TH, 2024 <br />SANTA ANA, CA BID & PERMIT SET <br /> <br />CAST-IN-PLACE CONCRETE 033000 - 5 <br />1. Do not cut or puncture vapor retarder. Repair damage and reseal vapor retarder before <br />placing concrete. <br />3.4 JOINTS <br />A. General: Construct joints true to line with faces perpendicular to surface plane of concrete. <br />B. Construction Joints: Install so strength and appearance of concrete are not impaired, at locations <br />indicated or as approved by Architect. <br />3.5 CONCRETE PLACEMENT <br />A. Before placing concrete, verify that installation of formwork, reinforcement, and embedded <br />items is complete and that required inspections are completed. <br />B. Deposit concrete continuously in one layer or in horizontal layers of such thickness that no new <br />concrete is placed on concrete that has hardened enough to cause seams or planes of weakness. <br />If a section cannot be placed continuously, provide construction joints as indicated. Deposit <br />concrete to avoid segregation. <br />1. Consolidate placed concrete with mechanical vibrating equipment according to ACI 301. <br />3.6 FINISHING FORMED SURFACES <br />A. Rough-Formed Finish: As-cast concrete texture imparted by form-facing material with tie holes <br />and defects repaired and patched. Remove fins and other projections that exceed specified limits <br />on formed-surface irregularities. <br />1. Apply to concrete surfaces not exposed to public view. <br />B. Smooth-Formed Finish: As-cast concrete texture imparted by form-facing material, arranged in <br />an orderly and symmetrical manner with a minimum of seams. Repair and patch tie holes and <br />defects. Remove fins and other projections that exceed specified limits on formed-surface <br />irregularities. <br />1. Apply to concrete surfaces exposed to public view. <br />C. Related Unformed Surfaces: At tops of walls, horizontal offsets, and similar unformed surfaces <br />adjacent to formed surfaces, strike off smooth and finish with a texture matching adjacent <br />formed surfaces. Continue final surface treatment of formed surfaces uniformly across adjacent <br />unformed surfaces unless otherwise indicated. <br />3.7 FINISHING FLOORS AND SLABS <br />A. General: Comply with ACI 302.1R recommendations for screeding, restraightening, and <br />finishing operations for concrete surfaces. Do not wet concrete surfaces.
