Forms shall be of wood, metal or other materials a:> <br />specified as shown on the Drawings or as approved by the Engineer. <br />1.02 Submittals <br />A. Deta>Zed drawings for formwork, falsework or centering shall be furnished <br />i the Engineer if requested by him; however, the Contractor will not be re•- <br />lieved of responsibility for results obtained by the use of these drawings. <br />r <br />B.• A sample of the form ties shall be submitted to the Engineer for approval. <br />1.03 Design Criteria <br />_. <br />A. Design of formwork shall include consideration of the following factors: <br />~ 1. Rate and method of placing concrete • <br />~` <br />2. Loads, including live, dead, lateral, and impact <br />~ 3. Selection of materials and stresses <br />4. Deflection, camber, eccentricity, and uplift <br />5. Horizontal and diagonal shore bracing <br />` 6. Shore splices <br />L <br />7. Cross-grain compression <br />8. Vibration of concrete <br />~_ <br />9. Loads on ground or on previously placed structure <br />B. Falsework <br />1. Falsework shall be designed to provide the necessary rigidity and to <br />~, support the loads without appreciable settlement. <br />L 2.
