TII284 - Luas Finglas Ground Investigations

Descriptions

Specialist Contractor required to carry out geotechnical ground investigation works to inform the preliminary design associated with the Luas Finglas Project. This will involve a range of exploratory holes, sampling, in-situ and laboratory testing. Sections of the alignment which are suspected to contain contaminated material will be sampled and undergo environmental laboratory testing to assess the nature of contaminants present, if any. This will provide more detailed, site specific information on the local ground conditions, including the depth and thicknesses of the soils and geology, and potential presence of contaminated ground. Several groundwater monitoring installations are included as part of the ground investigation works to facilitate regular groundwater monitoring in both the superficial and bedrock aquifers. Ground gas monitoring installations are also included at select locations to screen for potential ground gas. Groundwater level monitoring data will be used to inform the potential likelihood of groundwater flooding. The ground investigation contract will also establish the road/footpath composition, i.e. thickness of wearing course, base course etc.Possible Other Works At the absolute discretion of the Employer, this contract may be varied to include ground investigation works similar to that performed for Luas Finglas, at other locations in Dublin City and its environs, which relate to other public transport projects, which may include but are not limited to the following:•Luas Finglas - €500k (estimated value) •Metrolink - €200k (estimated value) •Luas Lucan - €150k (estimated value) •Red Cow – €50k (estimated value) •Carrickmines – €50k (estimated value) •Other light rail projects as required €50k (estimated value)
