Geotechnical services for single wind turbines up to 1mW rating.

 Includes: geotechnical report acceptable for the installation of wind energy converters, digital topographical survey and layout drawing.

 Topographical Survey

•             Locate and place marker peg for centre point of turbine, interpreted from planning consent specifications.

•             Survey topography within 30m radius surrounding turbine.

•             Provide a topography map as a digital .dwg file.

 

Geotechnical Survey

•             Drilling of 1 No. rotary cored borehole to provisional depth of 16m.

•             Provisional allowance of 4 No. super heavy dynamic probes and four continuous tube sample boreholes over foundation base area.

•             Installation of 1 No. ground water monitoring well to a provisional depth of 12m.

•             1 No. return visit to site to measure ground water level.

•             Associated sampling and on site in-situ testing as appropriate.

•             Trial pitting using JCB or similar equipment.

•             Geotechnical testing of soils.

•             In situ CBR and rocks.

•             Factual and interpretative reporting.

 

Layout Plan

•             Transpose Enercon standard access requirements onto topological survey plan.

•             Arrange site meeting with installation manager where site dictates variations from standard layout.

•             Provide layout plan to inform construction contractors, showing: finished levels, propose optimal cut and fill schedule, access route, crane pad, external electrical enclosure position (where applicable).

 

Target times:

•             Surveys within 2 weeks of order.

•             Lab report and advice on foundation type within 1 month of survey

•             Full report and layout plan within 6 weeks of surveys

Whilst we aim to provide a prompt response, times will be subject to supplier availability at the time of quotation.

 

Payment schedule:

•             60% to confirm order

•             30% on submission of Geotechnical report

•             10% on completion of site inspection and submission of layout plan

 

Fees:

•             Projects within 60 miles of Lincoln £16,500.

•             Arrange and attend site meetings to reconcile variations to standard access and lifting plans £100/ hour + £0.45p/mile.
