Datasheet
Description
Tejjy Inc. implemented Building Information Modeling for the expansion of the Water Purification Plant in the City of Houston, USA.
Project Facts at a Glance:
Project Name: Northeast Water Purification Plant Expansion (Building 213)
Project Location: City of Houston, Houston Public Works, USA
Client Company: Industrial and Municipal Supply
Project Type: Industrial
Trades Covered: Steel Support, Piping, Fabrication
Materials Involved: MS, Copper, PVC
Team Size of Tejjy Inc. – 3 Engineers
Project Specialty:
Small piping for process plant
Use of prefabricated modular construction technique through BIM
Unique Feature of the Project: Development of Fabrication Drawings, Pipe Spool Drawings & Process Equipment
Purpose of Construction: New process plant expansion for the city of Houston
Number of Buildings: 4 Buildings with different process equipment
Levels of Building: 2
Start Date of the Project: 16th January 2020
End Date of the Project: 28th February 2020
Start Date of the Actual Construction: 21st February 2020
Date of the Final Construction: On-going
Stakeholders Involved in the Project: Houston Waterworks Team - A CH2M & CDM SMITH Joint Venture
Role of Client: Pipe Subcontractor
Software Applications Used for the Project: Revit, AutoCAD
Project Scope of Work Executed by Tejjy Inc.:
Tejjy Inc. uses Revit for creating the 3D BIM Model to meet the project objectives like:
3D Revit Model Creation for Coordination and Shop Drawings
Constructability Review (Model Update to reflect changes resulting from Design Changes, RFI Generation & Update)
Clash Detection & Mitigation
Coordination of Piping & Process Equipment
Fabrication Drawing Preparation
Spool Drawing for Pipes
Quantity Take-off
Pre-fabrication & Modularization
Project Challenges & Solution:
Challenge 1: Fabrication Drawing Creation
- Solution: Team of Engineers at Tejjy Inc. developed a standard for executing the Fabrication Work.
Challenge 2: Coordination of Piping & Process Equipment
- Solution: Engineers of Tejjy Inc. detected pipe clash in the pump room using 3D BIM Model and processed equipment with the pipe.
Challenge 3: Incomplete Information in the Model
- Solution: Using BIM Constructability Review, the Engineers of Tejjy Inc. have found that the line & pinch valve are not updated in the model and don't have adequate space.
Benefits Obtained by the Project Owner from BIM Implementation:
Coordination of Piping & Process Equipment
Generation of Exact Quantity of Pipes & Equipment for Order Placement
Improved Understanding of the Fabrication Process
Optimized Operational Efficiencies for Fabrication
Dimension Correction as per P&ID (Piping & Instrument Diagram)
Complete Information Management through BIM Model
ROI from BIM:
Tejjy Inc. saved the time and money of the project owner throughout the building lifecycle by developing the perfect design and drawings through BIM. The technology helped to simplify the project work-flow using Revit BIM Model for coordination.
Percentage of Benefits to the Owners (%), from BIM Implementation:
100% Reduced Document Error
96 % Reduced Rework of the Fabricator
10 % Reduced Construction Cost by Not Ordering Excess Quantity
15% Faster Project Completion through Accurate Drawing Creation
Result of BIM Implementation
Using BIM, we could easily produce quality output with less effort
Enhanced quantity of production at lesser time
Detected accessibility issues, saving time for rework
Identified space constraint and facilitated waste elimination
Facilitated design disciplines to collaborate as a single information platform
Improved work efficiency, reducing errors & verifying aesthetics
Ensured ease of access for maintenance provisions & facility management
Saved Money through Pre-fabricated Modular Construction Model
