  1. Designer/Contractor JV- Apron Services Projects- A Winning Case The KAIA project Case Study

  2. Introduction • The purpose of this presentation is to demonstrate : • How early Engineer( designer/ Contractor coordination and cooperation can overcome the difficulties encountered • Highlight unforeseen and foreseen difficulties and challenges encountered in the KAIA project

  3. Introduction • AME- DEP JV • KAIA back Ground and Scope of Work • Project Constraints • Project Deliverables • Project Procurement Plan • Systems Design • Conclusion

  4. Designer / Contractor JV • AME Background • DEP Background • AME-DEP JV and history of cooperation • DEP Role in KAIA:DEP is doing design – shop dwgs – technical procurement submittals – construction management and cost control

  5. Project Background and Scope of Work • Client : GACA • Main Contractor : Saudi Bin Ladein Group – SBG • Apron Subcontractor – Al MabaniAGC • Apron Services Subcontractor – AME/DEP

  6. Project Background and Scope of Work Scope of Work: • Potable water treatment plants and potable water piping network from Tech. rooms to pits. • Blue water treatment plants and blue water piping from Tech. rooms to toilet pits. • Vacuum receiver plants and piping network. • PCA air handling units and corresponding under-gound ducting and PCA pits • Glycol chilled water plant rooms and networks. • GPU 400 Hz system and pits

  7. Project Background and Scope of Work Aprons 17-18-19 and PTB Area in scope

  8. Project Deliverables • Material Submittals • Design and shop drawings • Method statements • Monthly Progress Reports • O & M manuals • As Built Drawings • Testing and Commissioning Reports • Training • Warranties

  9. Project Constraints • The main constraints challenging AME at this project are the following: • The short project duration which is by any standards is very tight for the scope of work at hand . • The different layers of upstream parties, mainly the CM and designers , and at a second level Main Contractor and Subcontractors • The Various unforeseen changes from the original tender design due to site conditions / project updated requirements / cost and time constraints • The delays in design / approvals / material

  10. Project Constraints • The difficulty of direct communication between many of the parties due to contractual constraints • The peculiarity of some of the specified items such as: • Vacuum drainage system • Glycol sub cooling method • SS PCA Duct for mobile ACU • The interface with other contract packages which could increase the number of unforeseen problems.

  11. Why a Designer on Board is a Winning Case • The Complexity of the modern airport systems makes it necessary to do every bit of study and calculations and drawings to achieve a coordinated installation • To get seamless relations with the CM which is himself is an engineer • The various changes in design during construction due to site conditions requires a designer on board during the construction to find the proper solutions • When a Designer is in direct contact with the specialists / suppliers the design will be more customized and more understanding to the equipment strengths and weaknesses.

  12. Examples of Unforeseen Difficulties • Changes in the Client Requirements • Suppliers uncontrolled supply delays • Site level changes and various obstructions • Differences in Contract requirements interpretations

  13. Project Procurement Plan AME has prepared a procurement plan relating to time and cash flow to suit the project schedule and technical requirements. The basic elements of this plan are : Establishing a basket of reputable suppliers Providing proper material submittals for approval Identifying long lead items and placing orders on time Delivering the material on site as per project schedule
