INNOVATION

LASER SCANNING AND BUILDING INFORMATION MODELING When working in congested spaces such as mission critical areas, laser scanning provides a fast, accurate way to verify existing conditions. A laser scanning unit is placed inside the area where spatial data is needed. Within a matter of seconds the scanner compiles a digital model of the room that is easily converted into a solid model and inserted into our Building Information Model. Once the data is added to the model we can use it to plan and sequence the renovation work that is needed. Areas where there is limited space are easily identified and the dimensions are checked to be sure that new pieces of equipment will fit into the existing spaces. Laser scanning can also be used to verify existing conditions in areas that cannot be easily accessed. For example, the exterior dome of a building can be scanned from the ground without placing a worker on the roof. This saves time, reduces cost, and enhances safety because workers are not put in areas where fall protection or other special measures are required. Laser scanning is also sometimes used to scan work in place to ensure the proper fit of new assemblies. For example, before a curtain wall is installed we will scan the underlying concrete structure to verify that it was accurately positioned. We can then verify that curtain wall elements such as connectors or reinforcing brackets are correctly positioned and will precisely match the connection points on the concrete structure. If discrepancies are identified they can be resolved in the shop before the curtain wall units are shipped to the site. Once the units arrive on site they are then easily installed as field modifications aren’t required. The results are fewer delays, higher quality, and lower cost.

PREFABRICATION Through prefabrication JE Dunn has helped to mitigate construction difficulties including too many parties involved in the process, complexity and duration of the project and the equipment in data centers. Unlike traditional construction where components are installed separately onsite, prefabrication can reduce much of the time and cost risks associated with traditional data center deployment, while also future-proofing the data center investment to meet new demands. By taking advantage of this construction methodology, Owners can trust their data center to run smoothly and efficiently, and to meet the ever-growing demands of our highly functional business environment.
