Speaker: Gunnar Godawa – Hochtief ViCon

-Scheduling at the Nile Corniche Project

About the Qatar BIM User Day:

Qatar University, HOCHTIEF ViCon and Teesside University proudly take the initiative to facilitate modern and innovative methods in the Gulf construction industry. The focus is Building Information Modeling (BIM), and our aim is to establish a knowledge platform with government, research and industry experts. The User Day aims to help people to share knowledge, discuss new technologies, and identify new potentials for BIM.

2nd Qatar BIM User Day BIM Technology Case Study #1

  1. 1. BIM for Project Scheduling Case study: The Nile Corniche Project – Cairo, Egypt Gunnar Godawa HOCHTIEF ViCon Qatar W.L.L. Gunnar Godawa HOCHTIEF ViCon 1
  2. 2. 1. The Project The Nile Corniche Key facts: BIM Use Cases: Started in August 2008 3D Design Coordination 9,361 m² Footprint – ±200,000 m2 GFA Full Quantification from the 3D Model Includes a 5-star hotel and restaurants 4D Construction Model 37 stories 4-level parking facility ± 165,000m3 concrete ± 40,000t reinforcement Integration of BoQ and unit cost in the database 4D Progress and Cost Monitoring Gunnar Godawa HOCHTIEF ViCon 2
  3. 3. 1. The Project A collaborative BIM project setup • Project developer is the driver of BIM • BIM Manager coordinates 4D model and ensures quality of data delivery • PM/ CM uses BIM for project controls • Contractor provides the BIM services related to his scope of works • Project Developer BIM Manager PM/CM Designer Consultant Contractor Designer and Consultants use BIM results Gunnar Godawa HOCHTIEF ViCon 3
  4. 4. 1. The Project 3D Model creation 3D Quantity Model 4D Schedule and Progress Software Applied Use-case Software Overview of used software systems Gunnar Godawa HOCHTIEF ViCon 4
  5. 5. 2. Applied Use-cases Project phases and supported processes Design 2D ARC/STR 2D MEP Construction WBS Project schedule Cost estimate Specs. BoQ 3D model 4D model 3D design coordination 4D program verification 4D progress monitoring 4D cost monitoring Model based quantity takeoff User interface Design Coordination System Building Information System Gunnar Godawa HOCHTIEF ViCon 5
  6. 6. 2. Applied Use-cases Quantification from the 3D Model 1 3D Modeling 2 3D Quantity Take Off 3D model Consolidated 3D model Linking of Specification with 3D Model Specifications WBS Calculation of Quantities 3D Quantity Model Export of Quantities to the database © HOCHTIEF ViCon 4 Usage for Estimation and Scheduling 3 Bill of Quantities / Database Gunnar Godawa HOCHTIEF ViCon 6
  7. 7. 2. Applied Use-cases Quantification from the 3D Model – Success factors • Modeling Guidelines to ensure the reusage of the model in the project lifecycle • The 3D model is developed according to the project WBS • Additional attributes in the 4D model support the easy link with the schedule • Specs POMI 3D Model and QTO Split of 3D geometry and numerical data enable the flexibility to reuse data in various software tools BoQ Gunnar Godawa HOCHTIEF ViCon 7
  8. 8. 2. Applied Use-cases Verification of the Construction Program 1 4D modeling 2 4D schedule analysis 3D model Consolidated 3D model Constructability check and report Linking 4D Database Project Schedules Product integrity: Detection of errors Process integrity: Detection of conflicts © HOCHTIEF ViCon 4 Revision of schedules 3 4D program verification meeting Gunnar Godawa HOCHTIEF ViCon 8
  9. 9. 2. Applied Use-cases Verification of the Construction Program – Success factors • Ensure quality of 4D model by checking that all activities are linked to the model • Visualize the construction sequence to allow additional schedule analysis • Include automated verification of the resource distribution over time • Create reports to document the results of the program verification Gunnar Godawa HOCHTIEF ViCon 9
  10. 10. 2. Applied Use-cases Usage of the 4D Model for Progress and Cost monitoring 1 Progress recording Actual/planned working schedule 2 3 Update database & Visualization 4D Construction Progress Visualization 4D model update Actual/ planned Schedule Building Information System (BIS) 4D database © HOCHTIEF ViCon 4 4D progress monitoring/ 4D cost monitoring Gunnar Godawa HOCHTIEF ViCon 10
  11. 11. 2. Applied Use-cases Usage of a 4D Model for Progress Monitoring – Success factors • Define a database structure to ensure data integrity • Enable the team to access the project schedule without expert software • Implement regular progress updates in the project database • Integrate the provided information in regular project tasks such as progress reporting • Visualize the construction progress for better evaluation and common understanding Gunnar Godawa HOCHTIEF ViCon 11
  12. 12. 2. Applied Use-cases Collaboration in the project– One data pool Approach CM Contractor Management Procurement global Project project database data base Estimator Draftsman Scheduler Ensure quality and save time and costs through: • Re-usage of data by all stakeholders • Better collaboration through common data • Improved data interoperability Qto specialist © HOCHTIEF ViCon Gunnar Godawa HOCHTIEF ViCon 12
  13. 13. 3. Case study Project and Site Management – BIM interface • One single system with remote access to 3D model and information • Various project documents are integrated in database • Considers progress definition of planning department © HOCHTIEF ViCon Gunnar Godawa HOCHTIEF ViCon 13
  14. 14. Valuable Project Experiences Proven Team Benefits - Survey • Always current data available through remote access to the information • 4D/ 5D Model is continuously used for reporting purposes • Database with life-cycle approach will support later operation phase • Easy user interface supports the usage of BIM data Gunnar Godawa HOCHTIEF ViCon 14
