Description

The objective is to enlighten the community as to the incompatibility between construction documents (especially from regulatory specifiers like DOT, Corps of Engineers and Ministry of Transport) and requirements to deliver constructible, durable, sustainable and cost-efficient infrastructure.

Regulatory governmental construction contract documents are typically maintaining traditional prescriptive language in their tendered projects. This is creating a significant barrier for bidders to efficiently and practically deliver a successful infrastructure project. Traditional prescriptive requirements often include minimum cement contents, limit the proportions of supplementary cementing materials or utilize empirical limits that are unsubstantiated based on current materials, mechanical properties, and methods innovations.

They are also barriers to attaining more sustainable concrete construction. There is a reticence to migrate towards a performance approach which appreciates the depletion of raw materials sources and allows for innovation, sustainability, constructability, and cost effectiveness. On many infrastructure projects, specifiers do not appreciate the need to move to performance type documents and are combining prescriptive with performance creating confusion and contradictory messages.

Learning objectives:

1. Report on the current state of the art with respect to Performance Specifications and how they are in fact misrepresented by inclusion of prescriptive requirements.

2. Discuss the divergence and variation in performance requirements across the country.

3. Describe the strategies now being used in university programs to familiarize engineering students with the needs to be consistent in preparation of technical contract documents for performance.

4. Demonstrate the recent performance tests that have been developed to ensure compliance with a performance specification.
