MC-12 is a prestigious airport project undertaken by Pinnacle in Salalah & Muscat, Oman, spread over an area of 352,914 sq. m encompassing the Cargo Salalah, Cargo Muscat and MRO Muscat. The purpose of constructing the new Cargo facility at Muscatis to enhance connectivity to future Air Cargo Growth in GCC, Asia and Africa. Buildings of MC-12 project comprise of Salalah Cargo Complex including Main Building, Central Utility Plant, Security Building – Area A, B, C, Live Animal Centre, Plant Treatment Building, Dangerous and Radioactive Goods Storage and Muscat Cargo Complex including Muscat MRO Complex, Main Building, Pump House, Guard House and lots more.
Pinnacle executed the 3D BIM Modeling, Coordination and Shop Drawings for the MEPF (Mechanical, Electrical, Plumbing & Fire Protection) trades. Pinnacle involved a team of 55 BIM Engineers (35 In-house + 20 On-site Deputation), including project managers and collaborators located in Oman and India to provide BIM and BIM Engineering services for this infrastructure development.
3D Modeling, Clash Coordination, Constructability Review, Value Engineering & Shop Drawings
352,914 sq. m
55 BIM Engineers
Pinnacle created the 3D BIM Model (LOD 400) for MEP and Fire Protection trades for Muscat International Airport – Cargo & MRO area to meet the various project objectives including:
3D Model Creation in Revit for MEP and Fire Protection Trades
Coordination of the entire model in Navisworks (Clash Detection & Mitigation, Visualization)
Constructability Review (Model Updation to reflect changes resulting from Design changes, RFI Generation & Updation)
Comprehensive & Coordinated Service Drawings for complete coordination among all trades
Builder’s Work drawings for MEP penetrations through structural slab & walls
Shop drawing Creation of Mechanical (CHW & Duct Work), Plumbing (Drainage & Water Supply), Electrical (Light, Power, Fire Alarm & Containment), Fire protection & Builder Work (Slab & Wall Penetration)
Challenge: Large Volume of Work with Aggressive Deadline
The volume of the project was large with all MEPF services including:
Moreover, the overall project schedule was aggressive with the deadline for completion within 12 months.
Challenge: Implementing DASO Standard
Instead of traditional standards, unique DASO (Development of Airport in Sultanate of Oman) Standard was implemented for MEP Model and Shop Drawing creation in this project.
One DASO expertise was deputed at site to train all team members and communicate with clients and Pinnacle India.
Challenge: Inconsistencies in IFC design document
The IFC design documents had several inconsistencies that needed to be sorted out before the commencement of modeling.
Challenge: Coordination problem among various services owing to complex airport structure
Coordination among various services was difficult as the complex structure of the airport 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.
Challenge: Repeated Change in Architecture,Structure and Design
Pinnacle faced various design changes from client side, making an impact on MEP Model, Coordination and Shop Drawings. Engineers changed the tray/trunking size, light position, duct and pipe route at the time of shop drawing checking, involving a lot of rework for Pinnacle.
Pinnacle had to create shop drawings after the model was approved. An additional sheet of hours consumed was produced for approval.
Most of the plant rooms prepared by other vendors & documents were received after the completion of MEPF coordination. Hence, coordination with existing services became a challenge.Since the project volume was huge, Pinnacle faced the challenge of managing information, transmittal, RFIs and revisions. Moreover, it was difficult to track emails for decision making and resolving disputes.
BIM helped Pinnacle Infotech to plan using intelligent models and allowed Pinnacle team to anticipate, plan and coordinate every aspect of the project design, detailing and construction. It helped to identify constructability issues before construction by detecting the number of clashes, thus avoiding work stoppages, rework and wastage of time, material and manpower.
Mr. Pinaki Karmakar, Deputy Manager & Mr. Tanmoy Paul, Assistant Manager, Pinnacle Infotech said – “BIM software helped us progress through each phase of the project, starting from floor setup to structural and MEP clash detection. We have 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 BIM software for model design, we could easily produce drawings with various cutaways, elevations and sections, bringing the project to life. We used Revit models in Navisworks for project coordination and thus could avoid the cost of rework from the existence of clashes.” added Mr. Biswaroop Todi, Global Vice President, Pinnacle Infotech.
“Our team benefitted in terms of accuracy, data integrity, revision management, quality of detailing and higher productivity. We could successfully generate coordinated models and allowed our consultant to check possible interference building systems, leading to better project planning, reducing and reduced delay in construction. BIM solution played a vital role in design optimization, coordination and construction management. It was a pleasure to see that our BIM engineers worked in a coordinated manner, completing the project on time.” – concluded Mr. Bimal Patwari, CEO, Pinnacle Infotech.
