ACI Web Sessions are recorded at ACI conventions and other concrete industry events. At regular intervals, a new set of presentations can be viewed on ACI’s website free of charge.

After one week, the presentations will be temporarily archived on the ACI website or made part of ACI’s Online CEU Program, depending on their content.

ACI WEB SESSIONS

ACI conventions provide a forum for networking, learning the latest in concrete technology and practices, renewing old friendships, and making new ones. At each of ACI’s two annual conventions, technical and educational committees meet to develop the standards, reports, and other documents necessary to keep abreast of the ever-changing world of concrete technology.

With over 1,300 delegates attending each convention, there is ample opportunity to meet and talk individually with some of the most prominent persons in the field of concrete technology. For more information about ACI conventions, visit www.aciconvention.org.

Mandatory Code Requirements

An ACI code provides minimum requirements for concrete or masonry structures within its scope to safeguard the public safety, health, and general welfare.

ACI codes are written with the expectation that they will be adopted by a generalized building code or a regulatory agency. 

Code requirements are written to the design professional. 

They are not written to direct other members of the design and construction team, such as a contractor.

ACI WEB SESSIONS

Introduction to ACI 318

Drawings, specifications, and contract documents should contain all necessary requirements to ensure compliance with the code

Other ACI Publications such as ACI 301 Specifications for Structural Concrete are written specifically for use as contract documents for construction

CHAPTER 7—RECOMMENDED VIBRATION

PRACTICES FOR GENERAL CONSTRUCTION

7.1—General…Internal vibration is generally best suited for normal construction, provided the section is large enough for the vibrator to be effectively used. External vibration or consolidation aids, however, may shall be needed to supplement internal vibration in areas congested with reinforcement or otherwise inaccessible (Chapter 18). In many thin sections, especially in precast work and slabs, external vibration should shall be the primary method of consolidation.

ACI WEB SESSIONS

Referencing documents

CHAPTER 10—NORMAL-DENSITY CONCRETE FLOOR SLABS … 10.3—Structural slabs Structural slabs that contain reinforcement and embedded items such as conduits, pipes, pipe sleeves, etc., should shallbe internally vibrated. Vibrating screeds are also shallbe used to facilitate finishing; a high-frequency, low-amplitude type may shall be used in this case.

Definitions of Terms

The verb “shall” is used when a provision of this Specification requires action by the Contractor

2/17/2012

ACI WEB SESSIONS

Definitions of Terms

The phrase “Either…or…”is used when the Contractor is allowed to exercise an option when limited alternatives are available. 

ACI WEB SESSIONS

Definitions of Terms

The verb “will” is used to provide statements in the specification as information to the Contractor.

ACI WEB SESSIONS

Definitions of Terms

The verbs “may” or “will” is used to provide informational statements typically identify activities or options that “will be taken” or “may be taken” by the Owner or Architect/Engineer.

ACI WEB SESSIONS

Definitions of Terms

The phrase “Unless otherwise specified” is used when 301 is of the opinion that the default items may need to be modified by the A/E.  If this term were not used, there may be conflicts within the specifications.

ACI WEB SESSIONS

Definitions of Terms

The phrase “Unless otherwise permitted” is used when 301 is of the opinion that the Contractor may desire to ask for an alternative method.  This would require a submittal by the Contractor and acceptance by the A/E.

ACI WEB SESSIONS

The Mandatory Requirements Checklist  Work requirements regarding specific qualities, procedures, 

materials, and performance criteria that are not defined in requirements in the Project Specification.  This is used when there is not a default requirement in the specification. 

Used when the A/E must make a choice 4.2.2.7.a Sulfate resistance—Unless otherwise specified, provide 

concrete meeting the requirements of Table 4.2.2.7.a, based on exposure class for exposure to water‐soluble sulfates defined in Contract Documents. Submit documentation verifying compliance with specified requirements.

MRC 4.2.2.7.a—Designate in Contract Documents the exposure class for portions of the structure requiring concrete resistant to sulfate attack. Refer to ACI 318‐08 for description of exposure classes.

The Optional Requirement Checklist  The Optional Requirements Checklist identifies Specifier choices 

and alternatives. The Checklist identifies the Sections, Parts, and Articles of the ACI Reference Specification 301‐10 and the action required or available to the Specifier.  

When the phrase “unless otherwise specified” is used in 301, an optional checklist is generated to advise the A/E that he may need to specify an alternative requirement

4.2.1.3 Water and ice—Mixing water for concrete and water used to make ice shall be potable water unless alternative sources of water complying with ASTM C1602/C1602M are specified or permitted.

ORC 4.2.1.3 Specify if nonpotable water complying with ASTM C1602/1602M is permitted.

ACI WEB SESSIONS

The Submittal Checklist  The Submittals Checklist identifies information or data to be provided by the Contractor before, during, or after construction.  This checklist includes items that are to be submitted to the A/E or when the phrase “unless otherwise permitted” is used in 301, a submittal checklist item is generated.

4.1.2.8 Calcium chloride—When Contractor wants to use calcium chloride, submit a request including data demonstrating compliance with 4.2.2.5.

Reading Specifications• Specifications become critical during legal conflict

ACI WEB SESSIONS

Winners and Losers

ACI WEB SESSIONS

ACI WEB SESSIONS

A/E Spec Rule 1

Know what your specification states

ACI WEB SESSIONS

A/E Spec Rule 2

Determine the needs and wants of the owner and develop specifications that represent the requirements for the project, rather than those of previous projects.  Be assured that if the project is constructed within the project specifications, the owner will get the product that he or she desires.

2/17/2012

11

ACI WEB SESSIONS

A/E Spec Rule 3

Reference ACI 301 when the project is designed in accordance with ACI 318 or ACI 349; this assures the designer that the construction requirements that are in ACI 318 or ACI 349 are written in specification language.

ACI WEB SESSIONS

A/E Spec Rule 4

Strive to develop a reputation that your firm enforces the project specifications. This eliminates confusion both within your office and on the part of the contractor.

ACI WEB SESSIONS

A/E Spec Rule 5

State the project requirements concisely and only once

ACI WEB SESSIONS

A/E Spec Rule 6

Eliminate specification references to documents that are written in non mandatory language. They do not provide requirements and they will most likely make the specification confusing and unenforceable

ACI WEB SESSIONS

A/E Spec Rule 7

Do not use ACI 318 or ACI 349 as a reference in the specification unless the contractor will be required to develop plans and specifications for the project

ACI WEB SESSIONS

Contractor Spec Rule 1

Read the project specifications

Project specifications

2/17/2012

12

ACI WEB SESSIONS

Contractor Spec Rule 2

Review and understand ACI 301 and other reference documents in a project specification

ACI WEB SESSIONS

Contractor Spec Rule 3

Plan to construct the structure in accordance with the contract documents

ACI WEB SESSIONS

Contractor Spec Rule 4

Before agreeing to a contract, be sure you understand the project specifications and are willing to adhere to all of the requirements

ACI WEB SESSIONS

Contractor Spec Rule 5

Submit requests for information if the specifications have ambiguities, apparent omissions, errors, or conflicts.

Request for information

ACI WEB SESSIONS

What happens when the specifications are not met?

Meeting the specifications should mean that the projects is accepted as is.

Not meeting the specifications means that the variances must be evaluated to determine their impacts on the structure.
