NOTES TO SPECIFIER General notes G1. ACI Specification 330.1 is to be used by reference or incorporation in its entirety in the Project Specification. Do not copy individual sections, parts, articles, or paragraphs into the Project Specification, because taking them out of context may change their meaning. G2. If sections or parts of ACI Specification 330.1 are copied into the Project Specification or any other document, do not refer to them as an ACI specification, because the specification has been altered. G3. A statement such as the following will serve to make ACI Specification 330.1 a part of the Project Specification: “Work on (Project Title) shall conform to all requirements of ACI 330.1 published by the American Concrete Institute, Farmington Hills, Michigan, except as modified by these Contract Documents.” G4. Each technical Section of ACI Specification 330.1 is written in the three-part section format of the Construction Specifications Institute, as adopted for ACI requirements. The language is imperative and terse. G5. If ACI Specification 330.1 is used with another ACI specification that contains overlapping provisions, identify which requirements are in conflict and state in the contract documents which requirements control. (nonmandatory portion follows) FOREWORD TO CHECKLISTS F1. This foreword is included for explanatory purposes only; it is not a part of ACI Specification 330.1. F2. ACI Specification 330.1 may be referenced by the specifier in the Project Specification for any building project, together with supplementary requirements for the specific project. Responsibilities for project participants must be defined in the Project Specifications. ACI Specification 330.1 cannot and does not address responsibilities for any project participant other than the Contractor.

F3. Checklists do not form a part of ACI Specification 330.1. Checklists assist the specifier in selecting and specifying project requirements in the Project Specification. F4. The Mandatory Requirements Checklist indicates work requirements regarding specific qualities, procedures, materials, and performance criteria that are not defined in ACI Specification 330.1. The specifier must include these requirements in the Project Specification. F5. The Optional Requirements Checklist identifies specifier choices and alternatives. The Checklist identifies the sections, parts, and articles of the ACI Specification 330.1 and the action required or available to the specifier. The specifier should review each of the items in the checklist and make adjustments to the needs of a particular project by including those selected alternatives as mandatory requirements in the Project Specification. F6. The Submittals Checklist identifies information or data to be provided by the Contractor before, during, or after construction. F7. Cited references—Documents and publications that are referenced in the Checklists of ACI Specification 330.1 are listed below.

SPECIFICATION FOR UNREINFORCED CONCRETE PARKING LOTS AND SITE PAVING (ACI 330.1-14)

MANDATORY REQUIREMENTS CHECKLIST Section/Part/Article 2.1.1 2.1.5

2.2.4

3.1.1

3.2.1

3.4.1 3.6.9 3.13.2

Notes to Specifier General requirements Specify the exposure class of concrete in accordance with Section 4.2.2.7 of ACI 301. Exposure class for aggregates Specify the class designation for aggregates. Specify that the aggregates shall meet requirements of ASTM C33 for the specified class designation. Dowels and tie bars When dowels or tie bars are used, specify the type, size, shape, location, and spacing if not shown on drawings. Specify method of installation for dowels and tie bars. Subgrade preparation Specify subgrade preparation requirements including percent maximum dry density using current versions of either ASTM D698 or ASTM D1557. Subbase or treated subgrade Specify subbase preparation requirements including percent maximum dry density using current versions of either ASTM D698 or ASTM D1557, when subbase is required. When chemical treatment is required, specify stabilizing materials to be used for chemical treatment of the subgrade or subbase and the percentage cementitious materials by dry weight to be used. Embedded reinforcement in joints Specify joint locations to receive dowels or tie bars, when required. Final elevation Specify final surface elevations and pavement thicknesses. Jointing Specify joint types, locations, depths, and widths. The following provides guidance for specifying jointing. Specify locations of contraction joints, construction joints, and isolation joints. The maximum spacing between contraction joints is provided in the following table based on thickness of pavement: Maximum spacing between joints Pavement thickness, in. Maximum spacing, ft 4, 4-1/2 10 5, 5-1/2 12-1/2 6 or greater 15 The larger dimension of a panel should not exceed 125 percent of the smaller dimension. The minimum angle between two intersecting joints should be 80 degrees. Joints should intersect curved or skewed pavement edges at a 90-degree angle and extend straight for a minimum of 1-1/2 ft from the pavement edge, where possible. Align joints of adjacent panels. Align joints in attached curbs with joints in pavement. The minimum contraction joint depth, using a conventional saw, hand tools, or inserts, should be one-fourth of the pavement thickness. When using an early-entry dry-cut saw, the depth of the cut should be at least 1 in. for pavement thicknesses up to 9 in. and one-fourth of the pavement thickness for pavements more than 9 in. thick. Use isolation joints where pavement abuts buildings, foundations, existing pavements, manholes, and other fixed objects.
