MEP Civil

Our integrated approach to project coordination enables the highest level of efficiency and high-quality execution of construction involving mechanical, electrical, plumbing (MEP) and fire protection contractors. 

With extensive experience in providing MEP and fire protection solutions for projects both small and large, Castle Contracting is prepared to carry out successful projects in these categories. 

  • Excavation 
  • Trenching 
  • Directional Boring 
  • Concrete Services 
  • Pipe Handling 
  • Power Infrastructure 
  • Communication Infrastructure 
  • Rock Removal/Trenching 

Webster University

Electrical Customer Substation — St. Louis, MO

Situation and Challenges:

Castle was engaged to help with the delivery of an underground electrical distribution infrastructure project with minimal interruption to everyday campus life. The most challenging aspect of the project was working within active pedestrian and vehicular thoroughfares in a congested area to safely install high-risk utility infrastructure, using open-cut excavation and directional boring techniques. It was important to ensure traffic in these very active areas was not interrupted. 

Castle provided subsurface utility mapping and design-assist services, along with complete construction of the electrical infrastructure for campus distribution from a planned customer substation. That included approximately 5,300 feet of multi-conduit electrical ductbank and manhole structures.

Results:

By performing subsurface utility mapping to identify and pinpoint locations of existing utilities, Castle was able to deliver the engineering firm an accurate utility map to inform the overall design — which ultimately led to time and cost savings and reduced the original project budget from $1.5 million to $1.3 million. Castle developed a 4D model to communicate all aspects of the project to the project team and university personnel on a regular basis. Through a careful planning process, preconstruction budgeting services, and community outreach during the design stage, Castle set the tone for a zero-impact project. 

Pfizer, Inc.

Pfizer Research & Development Facility — Chesterfield, MO

Situation and Challenges:

The new 295,000-square-foot research and development facility houses Pfizer’s BioTherapeutics Pharmaceutical Sciences group and associated partners on a 32-acre corporate research campus. Working for the electrical contractor, Castle was hired to install power distribution and site lighting. The team installed concrete-encased ductbanks for power distribution, concrete-encased communication lines, excavated for grounding grid, and the complete site lighting package for the courtyard and parking lot. 

Results:

An accelerated schedule required site coordination between the Castle team and the mechanical and plumbing contractors on site. Different layers of MEPFP systems were installed at different times, and the team worked collaboratively to coordinate the staging of the work. The project was a success and completed on time and under budget.

BJC Healthcare

Public Realm Project — St. Louis, MO

Situation and Challenges:

Castle worked for an electrical contractor to install the power system for the new wayfinding signs located along two major, busy thoroughfares that border the Barnes-Jewish Hospital urban medical campus. The system required 6,000 linear feet of boring and 2,000 linear feet of trenching to connect existing panels and junction boxes to the new sign locations.

Results:

Castle worked along active roads and was able to utilize the parking lane to provide space for boring work. Because there were a lot of existing utilities around the medical campus, Castle coordinated work with the facility and contractors to avoid disrupting them. Since Castle performed subsurface utility mapping previously in the area, the team had utility location data to execute work efficiently and without incident. 

Missouri Botanical Garden

Stephen and Peter Sachs Museum Renovation — St. Louis, MO

Situation and Challenges:

Castle installed sanitary and storm sewers for the new addition to the museum at the Missouri Botanical Garden. This included a directional bore for a 10-inch combination sanitary storm sewer, hitting set flow lines elevations on each end. This required boring into an existing manhole on one end and then into a new manhole on the other end. The team had to directionally bore 500 feet so they didn’t damage vegetation and could keep the footprint small. With no laydown area, materials were delivered just in time. 

Results:

Castle self-performed all sewer work, boring, setting and piping. It is typical to directionally bore for electrical work or where elevations don’t affect how they work, but when boring for sewer, the flow lines are imperative, and that sets this job apart. During this project the team maintained constant pedestrian flow through gardens and worked around the tram schedule.
