CSE: What engineering challenges do office buildings pose that are different from other structures?
Jessie Jones: Predicting actual office building operations following construction can be challenging. Although we design buildings based on available usage information for our clients and on certain assumptions, it's up to owners and tenants to operate the facilities as designed for them to perform as intended. Changes in occupancy, program, and tenant schedules made throughout the design process and beyond can create cascading consequences with respect to construction scheduling/costs and building operational performance.
Charles B. Kensky: Design loads are based on occupancy and equipment usages and often differ across the floor plans and as well as from floor to floor. Meeting the outside air ventilation requirements on older high-rise buildings is a challenge due to the lack of outside air access. Varying occupancy demands, due to telecommuting, and increased power and cooling requirements for critical IT loads also add to the challenges. Varying occupancy in large training rooms and the increased ventilation requirements for open office spaces are a particular challenge, especially in older high-rise buildings. Other issues are personal comfort, proper temperature control and zoning, after-hours cooling, and how the tenant pays for this service.
Keith Lane: The electrical engineer needs to ensure there is the flexibility within the electrical infrastructure to provide the required load densities for today and tomorrow while still providing a cost-effective design. Additionally, on the telecommunication side, the electrical engineer must understand the client’s bandwidth requirements and ensure future proofing.
Andrew Thompson: Typically office buildings have fairly dense occupancy; ideally each occupant would be able to control its own environment. The individual environment is critical to productivity and ultimately the success of the project. Engineering systems that are able to adapt to the human element of a building is especially a challenge within an office environment.

These are typically not required features in constant flow systems, but constant flow systems use more energy over the life of the system. Pumps are generally selected with non-overloading motors, and pipe velocities are maintained at a maximum to
The inspectors also identified that the licensee had not updated the internal flooding analysis for Room 3101, essential service water pipe chase, following a planned modification to the essential service water supply and return headers.
Staff said potential surge pressures within the pipe could exceed the maximum pressure rating, increasing the likelihood of pipe failure and costly emergency repairs. “When we get a survey and design we'll have a more accurate cost estimate,” Chandler
One of three groups tours the North Las Vegas Water Treatment Facility. Large pipes with charcoal filters shunt away the odors normally associated with waste treatment. The group walks past a huge pipe that dwarfs the crowd. The hour-long tour barely
According to the latest plan, water would not flow from Stump to the coulee until the lake elevation rises above 1458 feet above sea level. Once it begins flowing, officials expect the coulee to begin eroding to lower elevations.
Experiments in Turbulent Pipe Flow with Polymer Additives at Maximum
We have used polymer solutions with three different concentrations which have been chosen such that maximum drag reduction occurs. The amount of drag reduction found is 60–70%. Our experimental results are compared with results obtained with water and with a very dilute solution which exhibits only a small amount of drag reduction.
