About The Project

MC-12 is a prestigious airport project undertaken by Pinnacle in Salalah & Muscat, Oman, spread over 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 the MC-12 project comprise of Salalah Cargo Complex, including Main Building, Central Utility Plant, Security Building – Areas 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 deputations), including project managers and collaborators in Oman and India, to provide BIM and BIM Engineering services for this infrastructure development.

BIM Scope of Work

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:

Comprehensive & Coordinated Service Drawings for complete coordination among all
trades

3D Model Creation in Revit for MEP and Fire Protection Trades

Builder’s Work drawings for MEP penetrations through structural slab & wall

Constructability Review (Model Updation to reflect changes resulting from Design
changes, RFI Generation & Updation)

Value Engineering

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)

Coordination of the entire model in Navisworks (Clash Detection & Mitigation,
Visualization)

Challenges and Solutions

Challenge

The volume of the project was large with all MEPF services including:

  • Sheet Metal
  • Chilled Water System
  • Smoke Control/Management System
  • Water Supply
  • Refrigerant Pipe
  • Cold Water System
  • Domestic Hot Water System
  • Sanitary Drainage System
  • Grey water system
  • Storm Water System
  • Fire Protection System
  • Solid Waste Handling System
  • MV Supply System
  • LV Supply System
  • Emergency Power System
  • Normal & Emergency Lighting System
  • Lighting Control System
  • Earthing & Lightning Protection System
  • Fire Alarm & Detection System
  • Wireless system
  • PCA
  • Paging
  • Security
  • Telecom
  • Structured Cabling system
  • Internet Protocol Television
  • Drainage
  • Compressed Air System
  • Building Management System (BMS)


Moreover, the overall project schedule was aggressive with the deadline for completion within 12 months.

Solution

  • PIS engaged a large team of over 50 engineers (including off-site and on-site) to work on this project. It was broadly divided into groups. Each group had its own sub group of 6-8 engineers with clearly defined targets.
  • In order to keep pace with the casting schedule, client’s casting program was sought and accommodated in the PIS schedule of delivery.
  • PIS worked with various software applications like AutoCad, Revit MEP, Navisworks and PDF viewer for quick and error free shop drawings & creating 3D coordinated model of Cargo, MRO &Ancillary Buildings.

Challenge

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.

Solution

  • One DASO expertise was deputed at site to train all team members and communicate with clients and Pinnacle India.

Challenge

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

Solution

  • The engineers checked and compared the IFC design documents for inconsistencies (for example the capacity of an FCU given in the plan should match with the same mentioned in the equipment schedule, riser diagram and submittal) and recalculated the data (sizes of pipe and duct, fluid flow rate, etc.).
  • Over 166 RFIs and 500+ queries were raised, where client’s decision was considered necessary. The RFIs were vetted by the PIS site team, reverted back with available information and submitted to clients for clarification.

Challenge

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.

Solution

  • Pinnacle BIM modelers made all efforts to ensure that the pipes and ducts can pass through the designated cutouts in the steel/beams. This was done by carefully shifting and altering the service routes, considering the access and clearance required and altering the sizes of ducts and pipes within allowable limits.
  • New unavoidable cutouts were substantiated with details like plan and sections. PIS site team used these details for the requirement of new openings.
  • At places where coordination was genuinely impossible, RFIs were sent to the consultant for lowering the false ceiling height.

Challenge

Challenge 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.

Solution

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.

Project Snaps

Value Addition and Summary

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.”
