TECHNICAL ACTIVITIES COMMITTEE
Chair: Fred Goodwin, BASF Construction Chemicals
TAC recommends, implements, and oversees technical activities consistent with policies established by the ICRI Board of Directors. This includes monitoring and oversight of all technical activities for content, progress, and compliance with approved policies. Activities include production of guidelines and other documents for use by the concrete repair industry as the committee deems necessary and appropriate and oversight of convention technical sessions, including selection of speakers and session moderators.
TAC adopted limited revisions to the review process for technical documents at the Spring 2014 meeting. A TAC subcommittee was appointed at the Fall 2014 meeting to conduct a detailed review of the current document development process and propose revisions as appropriate for TAC consideration. The goal of this subcommittee is to expand current guidance to include details on types of technical offerings from technical committees other than printed media and to streamline the overall production process. This document is intended as tool that can be used by committees from the beginning to the end of the development process.
TAC recently completed updating of the ICRI Technical Committee and Style Manuals. The two documents were then combined and successfully balloted. The 2015 TCM was uploaded to the ICRI website in March 2015 (see link above). Click here for the Technical Activities Committee Roster.
- TAC-A Technical Programs
Chair: Peter Golter, 3M
This subcommittee is responsible for selection of presentations for technical sessions at each ICRI convention. The Fall 2016 convention will be held in Cleveland, OH, November 9-11. The theme is "Urban Reconstruction." The deadline for submittal of presentation abstracts is July 11, 2016.
Chair: Fred Goodwin, BASF Construction Chemicals
Chaired by the TAC Chair, the Coordinating Committee is made up of the TAC Secretary, ICRI Technical Director, all ICRI Administrative and Technical Committee Chairs, and members of the Technical Activities Committee. This committee is designed to facilitate harmonization of document development and the committee operation process between ICRI committees.
The Coordination Committee’s training breakfast meeting had 27 attendees at the Spring 2016 convention. A video developed to introduce the strategic vision for ICRI Moving Ahead in the concrete repair industry was reviewed with positive reactions by committee members. Difficulties in transitioning from CAM to Ewald website were discussed. The supports current efforts to provide a system for web balloting. In the meantime, individuals, committees, chapters, etc. are encouraged to communicate any website issues or needs to Dale Regnier or Ken Lozen. A refined process for idea documentation and implementation covering alternative types of documents as well as technical guidelines was approved by the BOD March 11, 2016. Fred Goodwin presented a comparison of the “old” and “new” processes.
COMMITTEE 110 - GUIDE SPECIFICATIONS
Chair: Karl Rickert, Rickert Engineering, Inc.
The ICRI guide specification and commentary 110.1, “Guide Specifications for Structural Concrete Repairs,” was published in January 2016. The purpose of this guide specification is to aid the Design Professional in the preparation of technical specifications, for inclusion directly into contracts for construction of concrete repairs that are in line with the state-of-the-art materials and methods used in the concrete repair industry. Its primary focus is to provide an outline for developing the three parts of the specification through suggested text, references, and commentary for evaluating alternatives. The Committee is currently developing a PowerPoint presentation that describes the guide specification. They are also reviewing other types of repairs that might benefit from a guide specification.
COMMITTEE 120 - ENVIRONMENTAL HEALTH AND SAFETY
Chair: Charles Brienza, Concrete Protection & Restoration, Inc.The committee continues to explore potential methods for improved marketing of Technical Guideline No. 120.1-2009, “Guidelines and Recommendations for Safety in the Concrete Repair Industry” A presentation to introduce the Safety Guideline to ICRI chapters has been developed and is available for download and use by members HERE. A Spanish version of the guide was produced and introduced at World of Concrete 2013. A Task Group began reviewing Guideline 120.1 at the Spring 2016 meeting on preparation for revision of the document.
Three White Papers developed by Committee 120 can be downloaded from the ICRI website Free Publications page.
The committee continues to draft content for “Safety Solutions,” a new column that was introduced in the Mar/Apr 2010 CRB. The committee is currently working with the Awards Committee to include a “Safety” element in documentation for project awards. Also, they are planning to develop a “Safety Award” for annual presentation beginning in the Fall 2016.
COMMITTEE 130 - PROCUREMENT METHODS AND RELATIONSHIP ARRANGEMENTS
Chair: Leo Whiteley, Walker Restoration Consultants
The committee is developing a procurement document to provide guidance to owners, designers, and contractors on ways to formalize agreements among themselves to design and/or perform restoration projects. The guideline will discuss responsibilities and liabilities of each member of the restoration team, give examples of different contracting methods, and establish an ICRI recommended process to serve as the industry standard.
The “Guideline for Procurement of Concrete Restoration Services (130.2)” was reviewed by TAC and returned to Committee 130 for revision, reballot, and resubmittal. The committee discussed TAC comments at the Spring and Fall 2014 meetings. The document has been reformatted in accordance with TAC comments. Revised assignments were made (Spring 2015) for development of new text to address TAC comments. Plans are to return the document to TAC during the Summer 2016.
COMMITTEE 160 - LIFE CYCLE AND SUSTAINABILITY
Chair: Peter DeNicola, Evonik Corporation
Committee 160 drafted a chapter, “Sustainable Concrete Repairs,” included in the US Green Concrete Council’s book, “The Sustainable Concrete Guide – Applications.” A White Paper, “Sustainability for Repairing and Maintaining Concrete and Masonry Buildings,” was reviewed by TAC and approved for publication in April 2014. An Introduction to the White Paper was published in the Sept/Oct 2014 CRB. The entire White Paper can be downloaded from the Free Publications page.
The committee also drafted guidance on how sustainability issues can be addressed in other ICRI technical documents and criteria for the Awards Committee to use in judging nominations for a Sustainability Award (Spring 2014). The updated draft Sustainability requirements for Project of the Year Application Form was reviewed (Spring 2015) and committee voted to develop checklist for sustainability bullet points. Criteria for the Sustainability Award were approved and submitted for TAC review (Spring 2016). There were a number of questions about some criteria for the sustainability award, particularly carbon footprint, being available to those preparing nominations. Pete DeNicola, 160 Chair and TAC member will discuss these questions with the 160 and Awards committees.
A draft document, “Guideline for Evaluating Concrete and Masonry Building for Sustainability,” was posted on the 160 website following the Fall 2013 meeting. Subsequent reviews indicated that division into two individual guidelines for concrete and masonry buildings was preferable. Consequently, separate document development requests were submitted to TAC and approved at the Spring 2014 meeting. The committee reported (Spring 2015) that progress is being made on both guidelines. The committee reported (Spring 2016) that sections from the Life Cycle report will be incorporated into the concrete sustainability document. Plans are to complete this document by the end of 2016. A PowerPoint presentation will be created to lead the user through the process.
COMMITTEE 210 - EVALUATION
Chairs: Todd Allen, Universal Construction Testing/Radarview and Dennis Wipf, Gervasio & Associates Inc.
The committee request to develop a guideline, “Owner’s Guide to Inspection and Maintenance for Concrete and Masonry Buildings,” was approved by TAC at the Spring 2010 meeting. Questions for the Chico State repair industry survey were discussed at the Fall 2013 meeting.
Results of the survey were reviewed at the Spring 2014 meeting. Committee reported (Spring 2015) that they are focusing on describing symptoms (effects) to owners. Also, there was a Committee 160, Sustainability, member present at the meeting for coordination with the 160 owner’s guide. The subcommittee has been unable to establish the audience and focus of this document; therefore, the committee agreed (Fall 2015) that it should be transferred to the marketing committee for input as to whether or not it is needed and who the audience should be. This decision was confirmed at the Spring 2016 meeting and it was agreed to return this task to TAC. The results of this effort were summarized by TAC and provided to Committee 160, Life Cycle and Sustainability, to see if was of potential use to them.
The committee reported (Fall 2015) that they planned to create an educational program based on Guideline 210.3R–2013, “Guide for Using In-Situ Tensile Pulloff Tests to Evaluate Bond of Concrete Surface Materials.” This video and “how to guide” will be a companion document to the existing guideline. A Document Development Request for a 1 to 2 hour web-based educational module for applications, testing, and interpretation of in-situ pull-off tests was submitted to TAC at the Spring 2016 meeting. TAC approved the request unanimously.
COMMITTEE - 310 SURFACE PREPARATION
Chair: Pete Haveron, Texas Concrete Restoration Inc.
Guideline 310.1R-2008, “Guide for Surface Preparation for the Repair of Deteriorated Concrete Resulting from Reinforcing Steel Corrosion,” was published in March 2009.
A Task Group was formed at the Fall 2015 meeting to revise Guideline 310.1R. The group plans to complete the revision by Fall 2016. Revised Guideline 310.3R, “Preparation of Concrete Surfaces for Repair Using Hydrodemolition Methods,” was published in June 2014.
A committee request to develop a guideline “Surface Preparation of Contaminated Concrete,” was submitted to TAC in October 2014 and approved at the Fall 2014 meeting. TAC emphasized that the committee should concentrate on “how and where to use” appropriate methods and equipment. Detailed technical background on why procedures work should be minimized or avoided. It was reported (Spring 2015) that a small Task Group has been formed to start the document with plans to have a draft for review at the Fall 2015 meeting. There has been no reported progress on this document (Spring 2016).
COMMITTEE 320 - CONCRETE REPAIR MATERIALS AND METHODS
Chair: Ashish Dubey, PhD, FACI, USG Corporation
Guideline No. 320.3R-2012, “Guide for Inorganic Repair Material Data Sheet Protocol,” is available as a free download from the Free Publications page.
- 320-A Application Methods for Concrete Surface Repair
Chair: Peter Kolf, CTLGroup
The revised Guideline 320.1R-1996, "Selecting Application Methods for the Repair of Concrete Surfaces," was approved by TAC pending satisfactory compliance with review comments (Fall 2014). Committee 320 has proposed to update one section of the document in accordance with TAC comments and submit for a preliminary TAC review (June 2015) before proceeding with the entire document. Based on a preliminary review of three sections (September 2015), TAC concluded that the revised format was acceptable pending consideration of review comments. Plans are to update the remaining sections by July 2016.
- 320-B Materials for Concrete Surface Repair
Chair: Ashish Dubey, PhD, FACI, USG Corporation
Guideline No. 320.2R-2009 (formerly 03733), “Selecting and Specifying Materials for the Repair of Concrete Surfaces,” was successfully balloted in March 2014 with 4 negative votes to be resolved. The document was revised based on comments from the previous review and successfully balloted in January 2015. The revised guideline was submitted for TAC review June 2015. TAC approved pending compliance with review comments October 2015. Committee plans to address comments and return to TAC by August 2016 for a compliance check.
- 320-C Grout Material Data Sheet Protocol
Chair: Aamer Syed, Sika Corporation
The “Guideline Structural Grouts Material Data Sheet Protocol” was submitted for TAC review in January 2014. TAC returned the document to Committee 320 for revision, reballot, and resubmittal to TAC. The revised document was successfully balloted September 2015 with no negative votes and was submitted for TAC review March 2016.
- 320-D Pictorial Atlas of Concrete Repair Equipment
Chair: Andrew S. Fulkerson, MAPEI Corporation
Guideline 320.5R-2014, “Pictorial Atlas of Concrete Repair Equipment,” was revised to include a section on finishing and hand tools, approved by TAC, and published in May 2014. The committee is currently collecting information on other types of equipment (i.e. pumps, shotcrete equipment, slab jacking equipment) to expand the guideline. October 2015 is the estimated date for completion of another section.
COMMITTEE 330 - STRENGTHENING AND STABILIZATION
Chair: Greg Blaszak, PE, Milliken, Inc.
Guideline No. 330.1-2006, “Selection of Strengthening Systems for Concrete Structures,” was reapproved in 2012. The committee then initiated drafting of a guide specification and commentary for externally bonded FRP fabric systems for strengthening concrete structures. TAC approved the second draft of the document pending satisfactory compliance with review comments (September 2012). Subsequent revision of the document based on TAC and Committee 110 resulted in substantial changes that required reballoting and resolution of an additional negative. The revised draft was resubmitted for TAC review in May 2014. TAC approved the specification pending satisfactory compliance with review comments at the Fall 2014 meeting.
The objective of the Spring 2015 meeting was to resolve all remaining TAC comments. Responses to TAC comments were approved October 2015. The final draft was then submitted to TAC (December 2015) to determine compliance with review comments. Following format changes, the document was forwarded to staff for final edit and publication (March 2016).
A review of a draft outline for a FRP Applicator Certification Program (Spring 2015) generated significant discussion, questions, comments, and concerns. A revised outline was successfully balloted September 2015. A preliminary draft copy of the outline and comments were provided to the Certification Committee for consideration in advance of the Committee 330 meeting. Work assignments were made to committee members to supply slides/videos, etc., for the technical content of the FRP Installer certification program (Spring 2016).
COMMITTEE 410 - MASONRY
Chairs: Patrick J. Morrissey, ConSpec Associates, Inc. and John M Wathne, PE, Structures North
Guideline No. 410.1-2008, “Guide for the Evaluation of Masonry Facade Structures,” was released in March 2009. This guideline describes the tools, techniques, and processes that are used in the evaluation of masonry facade structures.
Following publication of the evaluation document, the committee began drafting a guideline for repair and strengthening of masonry facade structures. A committee ballot of the draft document was initiated in December 2013. Reports of ballot comments being resolved continue (Fall 2014). A meeting was potentially scheduled to follow the Spring 2015 meeting for resolution of remaining negative comments.
New topics and goals were discussed at the Fall 2014 meeting and the committee proposed to develop a series of guideline publications that are tentatively being called “Practice Guides.” A practical guide to structural in-place stabilization of distressed ornamental terra cotta units was selected as the first task. A document development request, “Practice Guide: In-place Stabilization of Terra Cotta,” was submitted to TAC and approved at the Fall 2014 meeting. TAC advised that the guide should emphasize “how to use” appropriate stabilization techniques and detailed technical background on procedures should be minimized or avoided.
Most of the Spring 2015 committee meeting was devoted to review and editing of the current draft of the Practice Guide. Plans are continue development of the Guide this summer with committee members submitting sections via e-mail. These will be merged into the master document for review and editing during the Fall 2015 meeting. Sections 1.0 through 4.9 of the Guide were edited at the Spring 2016 meeting and assignments were made for editing/drafting of additional sections prior to the next web conference. Assignments were also made for drafting of four case studies. Committee reported that web conferences between conventions have been very useful in document drafting and they will continue these monthly meetings in an effort to complete draft by Fall 2016.
COMMITTEE 510 - CORROSION
Chair: Matt Sherman, Simpson Gumpertz & Heger, Inc.
A committee request to develop an overall “Corrosion and Protection Guideline” was approved by TAC. The guideline will be a compilation of stand-alone documents with a long-term goal of an integrated document that will provide a single source of information on corrosion. Drafting of the document is currently on hold pending completion of other committee guidelines. Committee reported (Spring 2014) that they formed two Task Groups to develop documents that address corrosion rate testing and half-cell potential testing. The committee reported (Fall 2014) that the two task groups formed in Spring 2014 had been combined into one.
Consequently, a request for development of an overall guide for conducting corrosion testing was drafted. A detailed outline was also drafted and both were submitted to TAC. The request for development of “Guide for Conducting Half-Cell Potential, Corrosion Rate, and Resistivity Testing for Steel Reinforced Concrete Structures” and detailed outline were reviewed and approved by TAC at the Fall 2014 meeting.
Reportedly (Spring 2015) a significant portion of the Half-Cell section has been drafted. Task Group was adjusted to focus efforts and finish three sections by Fall 2015. It was reported (Spring 2016) that draft of Half-Cell section has been completed and posted for comments with a committee ballot expected by June. Committee 510 will then concentrate on the Resistivity section.
- 510-A Electrochemical Techniques for Corrosion Mitigation in Concrete Structures
Chair: David Whitmore, Vector Corrosion Technologies
Guideline 510.1, "Electrochemical Techniques to Mitigate the Corrosion of Steel for Reinforced Concrete Structures,” approved by TAC in January 2013 and published in June 2013.
- 510-B Corrosion Inhibitors
Chair: Tim Gillespie, Sika Corporation
The subcommittee has been drafting a guideline to provide information on penetrating surface treatments for corrosion mitigation of reinforced concrete structures. This information is intended to provide guidance and supplement sound judgment by engineers, consultants or others specializing in the restoration of reinforced concrete structures suffering from corrosion induced damage. As of the Fall 2013 meeting, approximately 75% of the committee ballot comments had been resolved. Committee reported (Fall 2014) that all primary ballot comments had been resolved. The document was submitted for TAC review at the Spring 2015 meeting.
The TAC Review Group recommendation to approve the document pending satisfactory compliance with review comments was approved by TAC September 21, 2015. P and S comments were addressed at the Fall 2015 Committee 510 meeting. Responses to TAC review comments were completed and approved by Spring 2016 committee meeting ballot. Document will be submitted to TAC shortly for compliance check
COMMITTEE 710 - COATINGS AND WATERPROOFING
Chair: Peter Golter, 3M
- 710-A Horizontal Waterproofing of Traffic Surfaces
Chair: Kevin Buck, Huntsman
Guideline 710.2-2014, “Guide for Horizontal Waterproofing of Traffic Surfaces,” was published in October 2014.
- 710-B Moisture-Related Issues with Concrete Floor Finishes
Chair: Lee Eliseian, Independent Floor Testing and Inspection
A request to develop a new document initially titled “Guide for Moisture and pH Testing, Collecting Data, Interpreting Concrete Results, and Mitigation Options” was approved by TAC in the Spring of 2010. An article summarizing subcommittee plans for the guideline and soliciting participation from additional members was published in the Jan/Feb 2011 CRB. The draft Guideline, “Moisture-Related Issues with Concrete Floor Finishes,” was submitted to Committee 710 for ballot in March 2014. The ballot was unsuccessful because at least 1/2 of all voting members on the committee roster did not cast an affirmative vote. The committee requested (Spring 2014) an MOU with SSPC on concrete moisture-related issues. Since SSPC is working on and has balloted their own similar document, SSPC will not be able to jointly participate with ICRI on this document.
The Chair reported (Fall 2014) that a task group of three had volunteered to “review and scrub the existing document as it is currently too lengthy and detailed.” Reportedly (Spring 2015) the guideline has been thoroughly revised and a subcommittee ballot will be initiated by May 2015. A successful subcommittee ballot closed December 1, 2015. Unfortunately, results of this ballot (list of voters, comments, etc. were apparently lost in the management company transition. Efforts to retrieve/reconstruct the ballot information are ongoing. Subcommittee proposes to address moisture mitigations options/solutions for exterior applications in future.
- 710-D Polymer Flooring Systems
Chair: Tom Murphy, Adhesives Technology Corp.
Guideline No. 710.1-2004 (formerly 03741), “Design, Installation, and Maintenance of Protective Flooring Systems,” was published as a joint document with NACE and SSPC. The Guideline contains detailed information on the aspects of flooring technology, performance properties, surface preparation requirements, installation procedures, and testing to help the user attain long-term service from a variety of polymer flooring systems in a wide range of applications. Subcommittee requested (Spring 2014) a MOU with SSPC and NACE for joint revision of the document. Both SSPC and NACE have agreed to participate in the updated guideline and an agreement between them and ICRI has been signed by all parties (Fall 2014).
The subcommittee plans (Spring 2015) to revise this document in modular format. Potential modules include:
• Concrete Repair (Joints, Spalls, Cracks, Overlays)
• Surface Preparation
• Moisture Mitigation
• Finish Flooring, i.e. Polymer Flooring
The subcommittee is continuing conference call with SSPC to revise the document (Spring 2016).
Chair: Mark LeMay, JQ
The Grouting Task Group produced Guideline No. 340.1, “Guide for the Selection of Grouts to Control Leakage in Concrete Structures,” in 2006. TAC disbanded the Task Group when ICRI adopted the current Committee structure and transferred responsibility for document maintenance to Committee 710 (Spring 2014) that Committee 710 initiate a ballot to reapprove this document, then begin a revision as appropriate. The committee reported (Fall 2014) that a subcommittee has been formed to revise the document.
Reportedly (Spring 2015) the document has significant deficiencies and should be completely rewritten. Draft #1 of the proposed outline for revision was reviewed and revised at the meeting. Also, the subcommittee proposes to revise the title to “Nonstructural Grouting for Leaking Structures.” Reportedly, editing of the revised draft is continuing through monthly Web-ex meetings with completion scheduled for Summer 2016.
Reviewed/Updated April 2016
