Actual Profile

Duncan Avenue Separated Sewer

In 2013 CGPS completed three utility mapping projects for TFC

• Total Cost - $70,000
• Each was Quality Level B

The cost of the associated construction (2400 lf of concrete encased ductbank and 2300 lf directional bore) totaled $1.1 million

• Each project was completed on time
• 2% change orders

•The only TFC project that was completed by others without the aid of CGPS Utility Mapping Services (700 lf concrete encased ductbank) finished 4 months behind schedule with "substantial" change orders

• Site Walkthrough w/ Facilities Personnel
• Call 811 Utility Locate Process
• Field Survey of Visible Surface Structures
• Deliverable of 2D Utility Exhibits w/ Labeled Elevations where available

• CGPS was contracted to provide SUM Services for the WUMC Campus. BJC determined varying standards of care, prioritizing the Phase I Renewal Project for the highest level of detail.

• CGPS produced deliverables in both 2D and 3D as a part of the services provided.

• At the present the completed subsurface utility modeling has allowed project designers to complete detailed subsurface tunnel and infrastructure designs through the required BIM delivery model

• Clash detection within the CGPS Model and the proposed design has provided improved conflict detection and QA/QC within the design process

• Preliminary site demolition and utility disconnects have already put to use the improved utility data – specifically the early disconnection and reroute of a live oxygen line that was found to be greater than 5 feet from it’s ‘as-built’ location.

• As this project continues, constructability analysis and accurate existing utility information for civil work packages are creating improved schedules and appropriate budgets for the project.

• BJC’s PMO acted as the owner for this civil infrastructure project - 1,600 lineal feet of 36" - 48" RCP at 12' depth - upstream extension to the CORTEX Separated Sewer
• Serves BJC, WUSM & SLCH

• CastleGPS ‘led the way’ for Castle Contracting in negotiating both the Subsurface Utility Mapping and Civil Construction for this $1,200,000 Project

• Project Team included CGPS as civil engineering consultant working for Castle Contracting to Design Assist the project.

Project Two -

Duncan Avenue Separated Sewer

• CGPS identified more than thirty critical utility conflicts
• Including an 8' X 10' X 40' deep concrete vertical shaft collecting storm and wastewater

• Accurate constructability assessments have been provided in approved MSD design variances

• Identified necessary utility relocations and abandonments (MSD, Lightcore Communications) allowing proactive Planning & Coordination

• Identified appropriate construction methods required to safely install the proposed line with appropriate lead times

• Design Coordination of 3 major alignment changes prior to MSD permitting

• Schedule Certainty for planned roadway closings and limited property access - Planned 4 month construction duration

• CGPS Mapping, Investigation, and Design Assist cost of $85,000 (QL A&B)

The CGPS Solution

Quality Level B

• Data Acquisition (Surface Geophysical Methods)
• Data Collection Data Processing, QA/QC, and Professional Review
• Update 'Utility Atlas' to reflect data collected

• CGPS will locate, depict & deliver accurate existing utility data and communicate it clearly with campus stakeholders

Quality Level A

• Nondestructive exposure of existing utilities
• Performed at project critical locations to enhance engineering design

Every Civil Construction Drawing Says something like this...

Existing Utility Problems

Campus Owners Need Solutions

Campus owners don't know what's under the surface.

It's unsafe.

The "million dollar hit" actually happens.

Grand Openings will be postponed.

“Underground facilities, structures, and utilities have been plotted from available survey and records. The owner does not warrant the locations of these facilities as precise. It is possible there may be others. The existence of which is presently not known or shown. It is the Contractor’s responsibility to determine the existence and precise location of all facilities and to avoid damage. See job special provisions for a list of utility companies on or within the vicinity of the project limits.”

Saint Louis campus for a high-quality owner, with expansion plans. More than 16 acres of total campus built over the past 40 years.

'Ideal Campus Plan'

Webster University Electrical Feeders

Our Team

The Project

• 5,300 lf of proposed electrical feeder lines (8 Cell, 4 Cell, and 2 Cell Ductbank)
• CGPS Completed QL-B SUM for the project limits at a cost of $82,000
• Castle Contracting negotiated the civil installation of the feeder lines for $1.1 million

The Results

• CGPS collaborated with William Tao and Associates to spur substantial redesign prior to the completion of 100% Construction Drawings
• Cost savings created by this effort exceeded $400K

• Design modifications allowed Castle Contracting, with the aid of CGPS, to present accurate schedule and operational details at multiple Webster Community Townhall Meetings

• The feeder line project is currently 75% complete with zero changes due to utility infrastructure unknowns and only positive schedule impacts

• CGPS is still engaged with Webster University to collect GIS Attribute information for the newly installed ductbank and update the University's Utility Atlas
