Who Takes the Risk on Your Construction Project?

Any facilities director or CFO who has been involved in a construction project has concerns about cost overruns and budget pressures.  When performed independently, the disconnect between design and construction can often lead to schedule delays and change-orders.  Fortunately, we have seen an increasing trend of owners, facilities professionals and public agencies getting specialized expertise involved early in the scope and RFP (Request for Proposal) development process, which helps define the scope appropriately, and in doing so, reduce the potential for cost overruns.

The Importance of Gearbox Engineering in Cooling Tower Installations

A recent article in Power Engineering International magazine raises a number of very valid points in cooling tower systems, particularly having properly engineered gear boxes to handle high heat, large fans and powerful motors. While the article is specific to industrial power plants, the approach is important no matter what the size of the cooling tower.

As the article states, “The speed reduction from gearboxes… optimizes the performance of the cooling tower fan. As fan diameters increase, the fan speed must decrease to maintain acceptable sound and vibration levels, as well as to ensure the structural integrity of the fan itself. Improper gearbox sizing as it relates to the motor and fan can result in excessive vibration, loud operation and structural damage to the tower.”

An experienced central utility plant design-build firm is aware of this and similar challenges posed by today’s systems, and specifies and installs equipment that has been designed to accommodate anticipated operating conditions. Too often, however, inexperienced construction firms simply do not have the expertise with critical system sub-components like cooling towers – and the sort of operational and maintenance considerations inherent to each. As we enter the heat of the season, this becomes even more apparent as facility directors try to balance efficiency, cooling capacity and system operational and maintenance needs.

If you are planning a cooling tower upgrade or replacement, make sure your contracting team has engineering expertise and experience with complex systems. Gearboxes for cooling towers are just one element of overall mechanical systems where specialized knowledge can pay big dividends and save money in the long run. If you have questions about your project, or just want to talk to a team of experts, get in touch with the Greenland Enterprises team.

The Importance of Experience and Expertise

A recent article in the UK publication Modern Building Services magazine provides a clear illustration of why experience and expertise is important in utility plant design and construction.  The article describes a project that replaced eight chillers on the roof of a BBC building, which would not be particularly noteworthy – except for the fact that the chillers failed prematurely due to being installed in an area that restricted critical airflow. Continue reading

Risk Management for Central Plant Systems During Construction

Central utility plant construction involves the installation or modification of mission-critical systems that must continue to perform during buildout.  Boilers, chillers, cooling towers and similar infrastructure can occasionally go off-line for planned maintenance, but certainly not for the extended time periods required in new construction.  Unfortunately, in many cases a new plant must occupy the existing footprint, adding to the planning required and increasing the potential for service interruptions or complications.
