Case Studies

Keyence Corporation – Open-ceiling Plan

Through early evaluation of existing conditions, Executive Construction developed strategies to deliver the client’s desired design intent.


Keyence Corporation relocated their corporate headquarters to an existing concrete building that housed several generations of tenants prior to their occupancy. For their new corporate home, Keyence desired an open-ceiling plan to maximize the ceiling height and volume of the space. Several existing MEP systems, the existing perimeter condition, and deep concrete beams presented obstacles in obtaining a clean design.

The initial approach was to examine the current layout and determine what areas needed to be updated aesthetically to ensure the architect’s design intent. The presence of acoustical ceilings posed several challenges for an open-ceiling concept. Any exposed wiring was to be evaluated in all areas to determine if any components would need to be relocated or removed, requiring time and careful coordination. Additionally, 100% finishing of the drywall up to the concrete deck was necessary above all exterior windows.

Executive Action

Using Bluebeam, Executive Construction’s superintendent overlaid the MEP drawings in the field to isolate potential conflicts with other trade foremen. As a value engineering (VE) option and cleaner design approach, Executive Construction worked with the HVAC trade contractor to develop strategies to surface-mount perimeter diffusers, thus avoiding the need for a perimeter soffit or grid system. A mockup was completed and painted in one quadrant so both Keyence representatives and the designer could approved the end result.


The entire open-ceiling area provided the clean concept and volume that Keyence desired, with very little conflict or adjustment to fixture location.
