Marmaray Cr-3 Project- Asia & European Side

ASIA SIDE
The summary of executed geotechnical investigations is as follows, drilling of a total of 30 nos. boreholes with core/soil recovery, sampling, carrying out of in-situ test in borehole like Standard Penetration Test (SPT), and performing of laboratory tests and preparation of factual report.

EUROPEAN SIDE
The summary of executed geotechnical investigations is as follows, drilling of a total of 7 nos. boreholes with core/soil recovery, sampling, carrying out of in-situ test in borehole like Standard Penetration Test (SPT), and performing of laboratory tests and preparation of factual report.

New Asghabat International Airport Project

The subsoil investigation report for New Ashgabat International Airport Project consists of field investigations such as borehole drillings (160nos), with standard penetration tests (SPT), permeability testing (lugeon or variable/constant head tests), pressuremeter tests, field CBR test, cone penetration tests (CPT), dynamic cone penetration tests, field vane tests, trial pits, in-situ density tests, plate loading tests, dynamic plate loading tests, seismic reflection tests, PS Logging and two dimensional electrical resistivity test.

Epcc Of Horizontal Drict Drilling And Power Cable Installation

The subsoil investigation consists of; drilling a total of 4 nos. boreholes together with Standard Penetration Tests (SPT).

The work provide power supply from Avaza (Mainland) to Kizıl-Su Island by Horizontal Directional Drilling (HDD) method to install trenches pipes to enable the power cable to be lay. Two horizontal drilling get a diameter 30cm have be carried out to installation of 2 nos X App.850m length Polyethylene Pipes (OD. 20cm) to pulling 10 kW Electrical Cables below 15m depth from sea bed level. 250 tons pulling capacity Horizontal Drilling Rig has been utilized to these drilling and pulling operation.
