Development of King Abdul Aziz Endowment for Two Holy Mosques in Makkah

Stage 1 : Central Podium Systems

Tasks :

• Vibration Monitoring System for Tower H.

• Displacement Measuring System Using GPS & Satellite for Tower H.

• Wind Speed Measurements on Structure for Tower H.

• Strain & Stress Monitoring System for Tower H using Embedment Vibrating Wire Strain Gauge.

• Tilting Measuring System for Tower F.

• Level Measuring System for Tower F.

The King Abdul Aziz Endowment project, which is considered one of the distinctive architectural marks in the 21st century, is the largest concrete project in the world and is implemented by the Saudi Bin Laden Group. Selecting the United Group Company as a company specialized in these systems to do this task The company has implemented the entire phase and the company has been following for four years following the systems after the end of the stage.

Stage 2 : Top Tower Steel Structure

Tasks :

• Strain & Stress Monitoring System for Top Tower Steel Structure using arc –Weldable Vibrating Wire Strain Gauge on the Critical Members.

• Automatic Data Collection & Logging System.

• Automatic Data Analysis and on line Monitoring System

• Automatic Web Monitoring to the results to be available Worldwide and Accessible to the Designer Remotely

The task Executed is Strain & Stress Monitoring System and it is installed in Selected Steel Members by MLP (Mayr Ludescher Partner (Consulting Engineers). In floors Under the Clock’s Floor, Sensors Were installed. Initial Readings and Flow up of the System from the Site and Remotely Were Considered. Remotely on-line Reading and Analysis Report Were Sent to the designer and Owner Every Two Weeks.

Stage 3 : Viewing Deck systems

Tasks :

• Install Two Complete Weather Monitoring Stations to Monitoring the Environmental Parameters From All Sides Of The Tower , And To Monitoring The Wind Speed Effects On The Tower.
