B. Embedded Items. <br />1. All conduits, pipes, fittings, and sleeves shall be permitted to be embedded in concrete <br />with the approval of Engineer and must satisfy all code requirements. <br />2. Anchor bolts, castings, steel shapes, conduits, sleeves, masonry anchorage, and other <br />materials that are to be embedded in the concrete shall be accurately positioned in the <br />forms and securely anchored. <br />3. Install conduits in walls or slabs with reinforcement in both faces between the two (2) <br />faces of reinforcing steel. <br />4. In slabs which have only a single (1) face of reinforcing steel, place conduits near the <br />center of the slab. <br />5. Unless installed in pipe sleeves, provide anchor bolts with sufficient threads to permit a <br />nut to be installed on the concrete side of the form or template. <br />6. Install a second nut on the other side of the form or template and adjust the two (2) nuts <br />so the bolt will be held rigidly in proper position. <br />7. Assure embedments are clean when installed. <br />8. After concrete placement, clean surfaces not in contact with concrete, or concrete <br />mortar and other foreign substances. <br />C. Preparation of Form Surfaces. <br />1. Remove mortar, grout, and other foreign material from form surfaces. <br />2. Coat form surfaces with form coating material before either the reinforcing steel or <br />concrete is placed. <br />3. Do not allow form coating to: <br />a. Stand in puddles in the forms. <br />b. Come in contact with the reinforcing steel. <br />c. Come in contact with adjacent hardened concrete against which fresh concrete is to <br />be placed. <br />4. Apply form coating to steel forms as soon as they are cleaned to prevent discoloration <br />of the concrete from rust. <br />D. Edges and Corners. <br />1. Place chamfer strips in forms to bevel exposed edges and projecting corners. Tool the <br />top edges of walls and slabs not indicated on the Drawings to be beveled. <br />2. Form beveled edges for all vertical and horizontal corners of equipment bases unless <br />indicated otherwise on the Drawings. <br />3. Chamfer strips shall be three-quarter inch (3/") unless indicated otherwise on the <br />Drawings. <br />Concrete Formwork February 2017 03100-5 <br />
