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

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
AME is an Aviation Systems Specialist company based in UAE and has presence in KSA and has references all over the middle east as my colleague T Sh explained in his presentaiton yest.
DEP is a design office based in Lebanon and has offices in KSA and projects in the Gulf and MENA regions

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

6. Project Background and 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

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

Chiller Supply
Avicorp recommends a single source for design and installation supervision of central glycol chillers and distribution network.
Here we see the KAIA installation, where Avicorp is providing design supervision, installation and supply. Three plus KM of pipe is being supplied and installed by Avicorp.

32. Systems Design Service Pits (400 Hz)
Or the most popular hatch pit designs. Note the easy access the supply cables…and the clear ramp with the covers closed. Simplicity of design, lack of an intrusive pop-up mechanism prevent jamming and damage from GSE movement.
