Fehmarnbelt, Geotechnical Verification Investigations 2015

Femern A/S

This procurement process covers the ‘Geotechnical Verification Investigations 2015’ for the Fehmarnbelt fixed link. The Geotechnical Verification Investigations 2015 constitutes an element in the ongoing geotechnical investigations for Design and Construction.
The marine operations are scheduled for the summer months, April through September 2015.
The scope of works for the Geotechnical Verification Investigations 2015 will encompass:
— Detailed planning, including establishment of a QHSE-plan and participation in authorities approvals
— Marine operations, i.e. shallow water platforms (3-10 m water depth), crew change and transport vessels, tugs, etc.
— Borings for sampling and CPT measurements. Some 84 marine borings to 10-40 m below seabed with the purpose of achieving high quality sampling (1.5 m) alternating with (1.5 m) CPT. CPT and sampling may be performed in separate boreholes.The borings shall be performed by applying shell & auger technique and sampling in non-coreable strata and high quality continuous wire line triple barrel coring in coreable strata, yielding minimum 100 mm cores. The CPT-technique to be applied may either be down-the-hole CPT with a stroke of 1.5 m with subsequent clean-out boring and a thrust of the minimum 80 kN or CPT pushed from the deck with a thrust of 100 kN.
— Bore hole pumping tests in selected bore holes
— Geological description and classification as well as core photos of the entire core samples
— Extraction of part samples for laboratory classification testing
— Performance of laboratory classification testing.
— Extraction and conservation of part samples for subsequent advanced laboratory testing by others
— Factual reporting of the findings in the form of GDRs, i.e. Geotechnical Data Reports, including descriptions of the works, boring profiles, geological evaluations, field and laboratory testing results, etc.
— Throughout the investigations, the Client's Geo Database system must be applied, enabling preparation of CPT and boring profiles as well as handling of laboratory data.
