Commissioning Smoke-Control Systems

Commissioning and acceptance testing demonstrate that the final integrated system complies with the design and that any modifications were correctly and successfully incorporated, so that the result is a properly functioning system. The design engineer must be involved with the test-and-balance contractor, the mechanical contractor, electrical contractor, controls vendor and fire-alarm vendor.

The Evolving Engineer

How important is the consulting engineer to the building team? In the 1970s, a typical reply probably would have been somewhat important. However, if one were to ask this question in the year 2001, a more likely response is very important.Yes, it's true.

Cooling Data and Dot-Coms

As data centers, clean manufacturing and telecommunications come to dominate many an engineer's design work, unique issues are impacting heating, ventilation and air-conditioning (HVAC) systems. From air purity and cable management to thermal decay and fire suppression, mechanical designers must smooth technical snags and hold down installed costs.

Liability May Lurk in Design-Build

Design professionals should understand that they are not insulated from lawsuits even if they are retained by a design-builder. From a legal standpoint, a designer in this situation has the same legal relationship as that of a subcontractor to a general contractor.

Value(-free) Engineering

Value engineering: Both the term and the concept are the roots of most evil in building design, I believe. Before you turn the page, please allow me to explain.First of all, "value engineering" is a misleading misnomer. It is rarely undertaken by an actual, licensed engineer, and the fancy-sounding endeavor is often little more than an exercise in cheapening a well-designed project.

Fox Studios’ Good Neighbor Policy

In the design of the new Child Development Center on the Fox Studios lot in Los Angeles, engineers from Syska & Hennessy chose to be good neighbors.Because the 10,000-square-foot facility with seven classrooms and an outdoor playground was to be located at the edge of the 52.9-acre lot, the facility's design had to take into consideration the concerns of a neighboring 20-story hotel.
