Q. Please tell us about Pinnacle Infotech’s work on “Rosslyn Central Place”.

Pinnacle Used BIM for Smooth Completion of Rosslyn Central Place Project

Project Summary – Rosslyn Central Place

One of the significant projects of Pinnacle Infotech, Rosslyn Central Place is a mixed use development, located above Rosslyn Metro Station in Arlington County, Virginia, USA with a 636,000 sq ft. Residential Tower & 750,000 sq ft. Commercial Tower. It is perfectly positioned with an easy access to Washington’s Central Business District and Georgetown. Phased turnover will begin in early 2017, it will provide an inspiring dining and retail space with integrated clientele living and working upstairs.

Located along the shores of Potomac River, Rosslyn Central Place is an exciting mix of residential, retail & commercial development. Designed by a famous architecture firm – Beyer Blinder Belle Architects and Planners, the glass façade of the RosslynCentral Place will soar to dramatic heights, offering amazing views of the District & Northern Virginia. Going further, an open-air public plaza with seating, shade and a robust programming schedule is expected to serve as the heart of the place. The project will also be home to the highest public Observation Deck and open air terrace in the Washington D.C. area at 443’-0” above sea level, with 360 degree views of the DC, MD and VA skylines. The panoramic views are anticipated to attract over half a million visitors annually to the front of Central Place.

BIM Scope for Pinnacle

Pinnacle created the architectural and structural models of Rosslyn Central Place that boasts of 33 stories (Ground Floor Level to 30th Floor Level, Floor 31 Penthouse Level, Roof Level) including the basement (B1, B2 & B3). The office space starts from 75 feet above street level on the 8th floor and the view just gets better. Pinnacle deployed a team of 10 BIM Engineers (In-house), including project managers and collaborators located in US and India to create 3D architectural and structural models of the 34 floors, including the level above Mechanical room.

Pinnacle’s scope of work also included:

• Creation of 3D Models (LOD 300) for Architectural & Structural Trades for MEP Coordination (Clash Detection & Mitigation, Visualization)

• Architectural Modeling elements like Exterior Walls, Interior Walls, Ceiling, Soffit, Doors, Windows (as per schedule), Stairs and Railings

• Structural Models of Beams (Primary & Secondary as per the beam schedule), Columns, Joists/Trusses, Structural Slab/Metal Deck, CMU/Pre-cast walls, Footing, Foundation, Equipment Support System, Steel/Concrete Stair and other Structural Framing Components

• Constructability Review (Model Update to reflect changes resulting from Design changes, RFI Update & As-Built Update)

BIM Process involved Pinnacle’s In-House Team, Client & Consultant

Challenges & the Way Out:

1: Timeline - Pinnacle faced the challenge of completing the models of all the 34 floors within 27 working days.

PIS approach:

• PIS engaged a team of 10 engineers, divided into two groups – one for the architecture and the other for the structural modeling with clearly defined targets.

• PIS used Autodesk Revit for successfully completing the 3D Models.

2: Input Inconsistency

The Construction documents set had several inconsistencies that needed to be sorted out before the commencement of modeling.

PIS approach:

• The engineers checked and compared the Construction Documents for inconsistencies.

• Comparison documents were submitted showing inconsistent parameters. The proposed solution were given by Pinnacle and client’s approval was sought for the change.

• Over 85 RFIs were raised, where client’s decision was considered necessary. The RFIs were vetted by the client, who in turn escalated the same to the consultant for probable solution.

3: Coordination Problem among Services

Coordination was difficult as the structure of the building did not allow any service to pass through the beam/concrete wall, unless it was not conceived at the design stage and the space between false ceiling and the true ceiling was inadequate in many cases.

PIS approach:

• At places where coordination was genuinely impossible, RFIs were sent to the client/consultant to change the false ceiling height.

Hurdles Overcome with the Help of BIM

Input Challenges – BIM helped sort inconsistencies that were found in the input drawings.

Incomplete Information – In many cases, floor beam sizes, specifications and elevations were not available in the input documents. BIM identified the need for providing revised ceiling height and beam sizes that would provide the actual plenum space for MEP services. Besides, there were incomplete information related to wall types and design layout for hotel and residential units. RFIs were raised to resolve these issues.

Constructability Issues/ Reviews – There were some conflicts between architecture and structure, which could have affected the actual construction in terms of time, cost, manpower, material, etc. BIM minimized all these wastages.

Value Engineering:

• Modified ceiling height design to suit site constructability

• Modified beam size design to avoid issue in site construction

• Coordinated MEP services with Existing Structure and Interior Drawings

• Detected Design and Constructability Issues

• Facilitated Complete Coordination among all trades

Value Addition:

• Over 85 RFIs were raised pertaining to Missing Data, Conflicting Data, Constructability/ Aesthetic Issues, Maintenance Issues and Accessibility Issues

• More than 100 Clashes were resolved from BIM implementation


Autodesk Revit helped Pinnacle Infotech to plan using intelligent models and allowed team to anticipate, plan and coordinate every aspect of the project design, detailing, construction and maintenance. It helped to identify constructability issues before the construction by detecting the number of clashes, thus avoiding work stoppages, rework and wastage of time, material and manpower.

Biprajit Nag, Deputy General Manager, Pinnacle Infotech said - “Autodesk Revit BIM software helped us progress through each phase of the project, starting from floor setup to structural modeling. Pinnacle has reviewed critical areas in 3D for any changes made and evaluated space constraint successfully. BIM facilitated various design disciplines to collaborate in a flawless manner as a single information platform, enhancing work efficiency, reducing errors, verifying aesthetic looks and improving building performance.”

“Using Autodesk BIM software, we could easily create models with the help of cutaways, elevations and sections. We combined Revit & Navisworks software platforms to coordinate with subcontractors’ models as well as other disciplines and thus could avoid the cost of rework from the existence of clashes.” – added Sourav Banerjee, Manager, Pinnacle Infotech.

“Autodesk Revit has slashed the time consumed and helped the project to move forward. By managing project info though Revit, our team was able to complete the modeling within the strict deadline, focusing more on better engineering, construction oversight and client satisfaction.” - concluded Bimal Patwari, CEO & Biswaroop Todi, Vice President, Pinnacle Infotech.

• MEP Contractor/Consultant - Dewberry

• General Contractor - Clark Construction Group, LLC

• Developer - The JBG Companies

Behind The Project:

Molly Raglani, Senior Project Manager - “Pinnacle was extremely responsive whenever issues arose. The desire to deliver a satisfactory product was very much appreciated.”

Mike Reisinger (Residential) – “Upon project kickoff, our project team was left with a complicated building design without a building model to coordinate with. Pinnacle Infotech quickly produced an accurate structural & architectural full building model to allow MEP coordination to begin almost immediately. Furthermore, the pinnacle detailers were extremely responsive when incorporating design changes into the program. More times than not, Pinnacle’s turn around when making model edits was less than 24 hours.”

P.J. Bombero, Project Manager (Office) – “The design of this project was completed prior to the use of 3D modeling and in order to perform MEP coordination a model needed to be developed. Pinnacle Infotech worked diligently with the team in order to produce the model in phases to allow the coordination process to begin on the below grade structure. The Pinnacle team worked to develop the model quickly, and provided multiple revisions based upon design changes from the Architectural and Structural design firms. Their quick turnaround and desire to provide a satisfactory model was essential in the MEP coordination process.”

1. Challenge - Collaboration Issue

Multiple Users Working Across Different Zones: In this precast concrete project, more than 40 people are involved in various segments to execute the model. As a result, it is difficult to progress the project smoothly. We required an effective collaborative software platform to increase the productivity and execute the construction process flawlessly. A cloud server (Model Sharing) is required to easily access the model and file with different time zones separately.

Solution - Tekla Software helped multiple users to work simultaneously in cloud server across different time zones of the world. We could easily work in Tekla without any trouble using master model sharing.

2. Challenge - Huge Number of Panels with Different Precast Elements

The precast modelling project involved 2228 nos. of precast wall panels, 5290 nos. of ribbed floor panels, 1250 nos. of beam panels, 4436 nos. of columns are involved and it was challenging to execute the project within the short & stipulated time frame specified by Clark Pacific.

Solution - After completing the reinforcement of the one panel, we reinforced the panels easily from one panel to another through ‘copy special’ command. This avoided the repeated work and saved time.

3. Challenge - Time-Line Challenge for Shop Drawing Preparation

Preparing quality shop drawings for all the panels within a short time was difficult

Solution - Clone drawing preparation is one of the key facets of using Tekla software. Using this process we created shop drawings for similar panels. It helped to reduce time for creating shop drawings.

4. Challenge - Difficulty in Maintaining the Numbering System of Reinforced Panel

In this huge precast concrete project, it is difficult to maintain the numbering system for all the panels. “Number system” is very essential to identify the particular panels as well as reinforcement for the whole project.

Working with “Numbering” system is a significant part of Tekla Software. If we required changing the Rebar Model, we have to execute “Perform Numbering” of this panel. “Perform Numbering” system helped us to easily get the bar mark of the Rebar from the model.

5. Challenge - Time-Consuming to Use Repeated Custom Components (Hardware)

Repeated use of components in precast panels likes embeds, hangers, lifters, couplers, etc.

We created lots of custom components for the purpose of modeling and used those custom components in the model.

6. Challenge - Schedule Constrain for getting BBS

Difficult to get the BBS in the shop drawing after reinforcement of the panels

We could easily get the BBS of the rebars from Tekla.

7. Challenge – Need to identify the Pouring

Pouring is essential in this precast project to identify which part is poured at a particular

Pouring is the most valuable option in Tekla. We showed the concrete model with different pouring in site.

8. Challenge – Need to identify the Phasing

Phasing is also essential for the purpose of representation and identification

Phasing showed the entire concrete model with different color regions (part by part or floor by floor). Consequently, it helped to easily identify a particular section of the entire concrete model.

9. Challenge – Need for Selection & Visibility Procedure

Selection & Visibility filter are also essential to select & identify a particular element or object from the entire model.

Solution - Selection as well as Visibility Filter is another significant aspect of Tekla. The software helped to identify any object with ease from the entire model.

10. Challenge – Difficulty in Calculating Panels for Site Transportation

Difficult to calculate the number of panels for Site Transportation - as a result of which the Transport Cost of the Pre-cast Contractor get enhanced

Solution - “Lotting” is the most important feature in Tekla. This helped us to easily measure group assemblies for transporting to site. Moreover, from this option we calculated the numbers of units of panels carried by the vehicle and the size of the panel for suitable vehicle.

11. Challenge – Need for Separate Environment – Drawing & Model View

Separate & specific environment required for drafting as well as model view for avoiding shifting of the model elements with changes in the drawings

Solution - In Tekla, the model and drawing environments are different, where we cannot move 'drawing' to the model environment at the same time. As a result, the final model was not edited/tampered with the shift in the model elements because of drawing change.


1. Using Tekla we have successfully completed 80% of drawing submission

2. Increased Work Efficiency, saving 40% time

3. Flawless Collaboration among stakeholders, reducing errors, improving building performance


1. Using Tekla, we are getting more quality output with less effort

2. Enhanced Quantity of Production at lesser time

3. Ensured ease of access for maintenance provisions & facility management
