Commercial fit-outs can be daunting – contractors require precise planning and coordination to ensure the structural layout and systems meet the design requirements of the tenant.
To create a comprehensive plan for building fit-out, construction and design teams can benefit from existing shell and core as-built site data in 2D drawings and 3D models to minimize rework and clashes, and coordinate trades.
Turner Construction was completing a building fit-out of 14,500 sq. ft. of existing core and shell space for a hospital in Philadelphia, Pennsylvania. The project scope included the construction of five new labs, one electrophysiology (EP) lab, one neuro lab, two cath labs, a flex lab, 11 pre/post bays, support space, a waiting room, equipment storage, and locker rooms.
The hospital had specific design requirements to build out the space, core and shell construction allowed them to customize the space to meet their healthcare needs. Turner Construction was hired to complete the building fit-out to the construction specs.
Core and shell construction refers to the first phase of a commercial project where the foundation and structural skeleton, or core, and the exterior building envelope, or shell, are constructed without adding interior walls, ceilings, MEP systems, lighting, furnishings, and other interior building elements.
The Virtual Design and Construction (VDC) engineer requested a 3D BIM model for design planning, project coordination, and construction scheduling. With a BIM model, the VDC engineer can create a comprehensive plan for building fit-out and MEP coordination.
Turner Construction hired GPRS to 3D laser scan the building core and shell and deliver point cloud data, 2D drawings, and a 3D BIM model of the space.
“Creating a 3D BIM model of your project site can be the single most powerful pre-construction activity for project success,” said Michelle Colella, GPRS Mapping and Modeling Manager.
Nemours Children’s Health Infrastructure Expansion
For Nemours Children’s Health, the lab spaces featured high-tech equipment and workstations with meticulous attention to detail during construction. The pre/post bays required essential connections for power, emergency measures, data, CO2, air, and specialized gases. Support rooms were equipped with regular and emergency power, with emergency power connected to a rooftop generator for uninterrupted operations.
Hospital infrastructure expansion requires significant planning to adhere to strict regulations, install advanced equipment and technology, and ensure the safety of patients.
Design-Build with 3D BIM Models
3D BIM models deliver a single source of data for design and construction teams who see the project through from start to finish — from engineering through pre-construction planning to estimation, schematics, subcontracting, and construction.
A Design-Build Institute of America Study from 2018 revealed how much time and money design-build saves when compared to other delivery methods. The benefits of design-build are impressive and tangible – compared with traditional contracting methods, design-build is 33% faster and costs 6% less. Design-build projects are delivered faster and with fewer change orders that lead to unforeseen costs and schedule delays.
To create a 3D BIM model of the building’s core and shell, site data must be captured with 3D laser scan technology. 3D laser scanning captures the spatial geometry (x,y,z coordinates) of a site in the form of a point cloud. Point cloud data is imported into a CAD/BIM software, such as Autodesk, where the data is turned into 2D drawings or 3D models at any level of detail. At GPRS, highly trained Project Managers ensure successful data capture and registration, and the Mapping and Modeling Team delivers precise CAD drawings and BIM models.
GPRS’ Delivers Data via SiteMap® Software
When you partner with GPRS, all data, including 2D drawings, and 3D models can be delivered via our new infrastructure data platform, SiteMap®. SiteMap® is a cloud-based software that stores up to date as-built records and site assets in an easy-to-use interface for project planning. As soon as the 2D drawings and 3D BIM models are completed by the GPRS Mapping & Modeling team, they are uploaded to SiteMap® to begin design-build planning.
Depending on which SiteMap® subscription tier you choose, every member of your team can have their own login to SiteMap®, to access accurate site information via desktop or mobile devices to make critical decisions. You can share data and models with subcontractors, engineers, and stakeholders to keep your project on time, on budget, and safe. GPRS’ data in SiteMap® improves project planning, mitigates risk, and improves communication for your team.
Nemours Children’s Health Case Study
Problem:
- The building shell existed, including the foundation, structural skeleton, columns, beams, and fire piping.
- A BIM model was requested to complete the design, minimize clashes, and plan for field coordination.
- The VDC engineer wanted each trade to conduct their specific work without interference from other trades.
Solution:
- A 3D Revit model was created from the point cloud with standard detail of architectural, structural, and MEP features.
- A reflected ceiling plan, an architectural drawing that shows visible objects located on the ceiling of a space, was delivered for MEP coordination.
- 2D plans and 3D models allowed this client to complete the design, communicate the scope of work to each trade, and efficiently schedule work to be completed.
Benefits:
- Model-based implementations are the foundation of our client’s VDC department. They plan site layout and work sequencing for efficient logistics and safety.
- The VDC engineer received an accurate 3D BIM model to design all building and MEP system components.
- Effective planning and communication minimized trade interference, clashes, installation problems, rework, and added costs.
Client Testimonial: “I am very happy that your team was expeditious with the scanning and the model creation. My last experience with a different company did not go as smooth and I am glad to have found a reliable company to work with in the future.” Joseph M. – Project Superintendent
Nemours Children’s Health Investments in Infrastructure
Turner Construction completed this project for Nemours Children’s Health in Paoli, Pennsylvania. Paoli has seen a huge increase in residents to the area, the current facility far exceeds maximum capacity in visits.
“Investments in our healthcare infrastructure benefit the entire community and add to the strong and healthy quality of life throughout the region,” said Pennsylvania State Senator Carolyn Comitta.

Frequently Asked Questions
What is a VDC Engineer?
Virtual design and construction (VDC) engineers manage the planning, visualization, and computer modeling of building projects. They work closely with BIM modelers, architects, and clients to create a cohesive construction plan.
What is 3D BIM Modeling?
Building Information Modeling (BIM) is a digital representation of the physical and functional characteristics of a building. Used for designing, constructing, and managing buildings and infrastructure, BIM provides a comprehensive digital model of a building, including its components and systems.
How Is BIM Used in Construction Management?
BIM modeling can help to improve construction management by increasing the accuracy of project estimates, reducing the number of change orders, and improving safety on the job site. BIM can help to streamline the construction process, by allowing the project team to access and share information in real-time. As a result, BIM has the potential to greatly improve the efficiency of construction projects.
