In order to study the feasibility of a trenchless construction site, Eurohinca requires plan and profile drawings, length, diameter, depth, geotechnical, water table, affected utilities, well spacing, access, work restrictions and target time frame. With these data you can assess the construction method, the main risks and the preparation of a technical-commercial offer.
According to Eurohinca, a specialist in Trenchless Technologies since 1996, in a preliminary phase it is not always necessary to have the complete project, but it is necessary to have enough information to analyze the constructability of the crossing, pipeline, outfall, catchment or subway infrastructure.
This data makes it possible to decide whether the solution can be implemented by means of pipe ramming, horizontal directional drilling, Direct Pipe or other trenchless technology.
Minimum recommended information
Geometric data of the layout: plan, longitudinal profile, total length, inlet and outlet elevations, expected depth, slope, radius of curvature if any, and admissible tolerances of axis and elevation.
Driving characteristics: inside and outside diameter, pipe material, intended use -sewer, supply, gas, drainage, outfall, catchment or other service-, service pressure if applicable and tightness requirements.
Geotechnical and hydrogeological information: borings, geological profiles, available tests, presence of rock, boulders, mixed soils, abrasive materials, water table, permeability and possible water pressures.
Environmental conditions: infrastructures crossed, existing services, nearby buildings, roads, railroads, waterways, urban areas, protected areas, easements, known permits and environmental limitations.
Space available for civil works and logistics: possible location of attack and reception shafts, available dimensions, access for machinery, stockpile areas, traffic restrictions, power supply, sludge or excavated material management and lifting conditions. This information helps to size the vertical pits for driving and microtunneling and the civil works associated with trenchless technologies.
Client's objective and requested scope: project phase, target time frame, expected scope of Eurohinca - feasibility, technical assistance and engineering for trenchless construction sites, The documentation required for bidding, RFI or RFQ.
Depending on the geology, the presence of water and the project tolerances, this information also helps to make the choice of tunnel boring machine, to evaluate the use of hydro-shield for water-logged terrain and select the most suitable excavation system.
Minimum checklist for submitting a technical inquiry: ground plan, longitudinal profile, length, diameter, depth, geotechnics, water table, affected utilities, location of wells, access, work restrictions and target time.
Request a preliminary feasibility review or a bid for a trenchless construction site attaching plans, longitudinal profile and available geotechnical data.
