Forms, shores, and re-shores are a temporary structure that carries the weight and construction load of the permanent structure until it is strong enough to stand up for itself.  While serving this temporary duty, forms, shores, and re-shores impact construction safety, cost, productivity, and schedule, and influence appearance, deformations, tolerances, and cracking of the hardened reinforced or prestressed concrete. 

This presentation introduces Codes, standard specifications, OSHA, and ANSI documents that address responsibilities for forms and shores.  By an example of a multi-story building, we look at how shore and re-shore systems work, including how shoring & re-shoring plans must be synchronized with rate-of-strength-gain of the concrete, as influenced by mix-design and ambient temperature.  This complex topic demonstrates how schedule, concrete mix, weather, construction technology, lab and in-place testing all come together.

This presentation reviews failures, damages, and other incidences of poor performance in concrete structures that have served to shape today's building codes and the standard of care for the profession. Examples range from well-documented, high-profile collapses to lesser known but similarly influential structural and serviceability problems. Case histories will include discussion of excessive cracking, the cause of such distress, and mitigation measures. The case histories will illustrate how small details can often mean the difference between success and disappointment; and how codes have evolved to reduce the risk of future failures.

A lot is known about Type I Construction (non-combustible) because it has been used for decades for multi-story construction.  Although Type IV Construction (heavy timber) is not new, it is just now beginning to be used with greater frequency in multi-story construction. This presentation will provide an overview of the building code as it relates to Type I and Type IV Construction. Case studies will be used to demonstrate relevant code sections that apply to Type I and Type IV buildings using the current Minnesota Building Code including:

    Chapter 5 – Area and Height limitations of Type I and Type IV
    Chapter 6 – Fire Rating requirements for Type I and Type IV
    Chapter 7 – Fire and Smoke requirements, shafts, sound assemblies  
    Chapter 9 – Fire and Life Safety requirements of Type I and Type IV
    Chapter 23 – Wood and heavy timber construction.  

In addition, materials and special inspections will be discussed for each type of building.

Like any industry, the construction sector is heavily influenced by technology. Even more so in recent years. While materials such as concrete might not conjure images of sci-fi films, lasers and androids, the industry itself has been immeasurably shaped by technological innovations, and this is set to continue. This presentation will discuss current and future technologies that will help automate processes, boost productivity, increases savings, and assist in reducing carbon emissions, all while improving communication and collaboration amongst all construction trading partners. New technologies like in truck concrete monitoring, sustainability trends, fleet tracking, inbound materials management, and other new technologies will be discussed.
