Description

This is a recorded webinar series from June 13 - 16, 2016.

This four-part webinar will present content on Troubleshooting Concrete Forming and Shoring. Presentations will cover forming systems and economics; loads and pressures; shoring, reshoring and stripping; minimizing excessive slab deflections, eliminating costly rework for out of tolerance alignment; techniques to avoid formed surface imperfections; and avoiding problems reducing cracking and deflections resulting from premature shoring removal.

Table of Contents

Learning objectives:

Part 1 - Forming Systems and Forming Economics:

1. Explain commonly used forming systems including wood wall forms, panel forms, gang forms, and more.

2. Give examples of various wall and column systems used for formwork.

3. Describe the economics behind using formwork systems, particularly design repetition, dimensional standards and dimensional consistency.

4. Discuss horizontal and vertical design techniques for formwork; and note the differences between the systems.

Part 2 – Loads, Pressures, and Reshoring of Multistory Buildings

1. Summarize formwork loads and the process of shoring and reshoring techniques for multistory buildings.

2. Explain the calculation of lateral loads.

3. Examine the distribution of pressure on the formwork from the freshly placed concrete.

4. Define shore, reshore, and backshore, and explain when each should be used.

Part 3 - Form Removal and Tolerances

1. Discuss the standard form stripping times in ACI 347.

2. Summarize the testing methods used to evaluate concrete strength for determining formwork removal, including: field-cured cylinders, penetration resistance, pullout test, break-off test, and the maturity method.

3. Identify the importance of tolerances in concrete construction.

4. Determine how and when to measure tolerances.

Part 4 - Formed Surface Defects Finishes and Formed Surface Defects

1. Identify formed surface defects (honeycomb, air voids, form streaking) and preventative measures to improve the aesthetics of formed surfaces.

2. Describe the differences in rubbed finishes (smooth-rubbed, grout-cleaned, and cork-floated).

3. Give examples of surface defects that should be outlined by a sawcut.

4. Outline surface requirements necessary for finishes by other trades (i.e. painting).
