estled against the foothills of the Rocky Mountains, the 
new Trimble Rockies Campus in Westminster, Colo., is 
a beautiful, glassed-in building that blends character 

and functionality. Construction of the  four-story, 11,613 m

(125,000 ft

) structure began in May 2012 and served as the 

demonstration project for a wide range of collaboration 
technologies used throughout the fast-track, 13-month con-
struction schedule. 

The planning and construction of the Trimble Rockies Campus 
is an impressive demonstration of how technology can help 
coordinated project teams drive efficiency, reduce waste and 
deliver a quality solution quickly and accurately.

The project team, led by Oz Architecture (architect) and JE 
Dunn (general contractor) with significant input from Trimble 
building construction experts, sought to implement integrated 
project delivery (IPD) techniques and strategies to gain the life-
cycle benefits of BIM. Key in the delivery of the building was 
the development of a dimensionally accurate model for design 
and construction coordination, detailing, fabrication and field 
level management. 

Documented efficiency improvements began right from 
the start. For instance, thanks to design-to-field connections, 
the team achieved 100-percent embed placement and zero 
placement errors during steel frame layout. The structural 
steel erection was completed in 10 weeks with no "fall-back" 
work. The mechanical, electrical and plumbing subcontractors 
realized 50-percent or better improvement in field layouts as 
compared to previous projects. 

Multiple project team members utilized Tekla BIMSight soft-
ware for construction model collaboration, conflict checking 

and site inspections. As the development of the dimensionally 
accurate federated model—architectural, structural and me-
chanical/electrical systems models all in a single model—of 
the site and the structure continued, JE Dunn's field team 
utilized model-to-field processes using Trimble's robotic total 
stations for stake-out and verification of anchor-bolt and em-
bed locations.

Fast Surveying
Initially, surveyors used the Trimble DiNi® Digital Level for high-
accuracy vertical measurements to transfer elevations from the 
reference benchmark to the site control points. Surveyors also 
used the Trimble S6 Total Station to complete the closed-loop 
traverse of the new building site. They were especially happy 
with the efficiency of the system, stating that they were able 
to measure points in 2 minutes instead of 30 minutes while 
maintaining exceptional accuracy. 

The S6 traverse and DiNi leveling observations were processed 
in a single Trimble Business Center project. A simultaneous net-
work adjustment of the observations yielded highly accurate 
control-point values, which served all subsequent positioning 
tasks on the site. 

A Trimble RTS655 robotic total station with a 360-degree 
Trimble MultiTrack target was used to verify control and set 
curb lines. To begin the process, pre-defined points from the 
civil and structural engineering models were uploaded to the 
Trimble Tablet Rugged PC running Trimble Field Link construction 
layout software. Primary control points—accurate to 0.32 cm 
(1/8 in) over 305 m (1000 ft)—were installed on drilled piers 
and dialed in with surveying control points. The earthwork and 
electrical subcontractors used the control points and curb lines 
to ensure exact grading in required locations, stockpile topsoil
