I work for the Crossrail systemwide contractor ATCjv whose role is “To safely and efficiently transform Crossrail from a programme of projects into a fully integrated and commissioned operational railway for London."
We are laying the track and installing the systems (power, signaling, drainage and so on) that service the railway.
As part of our commitment to innovation and safety we have commissioned a drilling machine/robot in order to automate the placement of the fixings for the in-tunnel systems. This machine will work in the 42KM of bored tunnel that is part of the Crossrail route.
The basic issue at hand is to resolve the positions of the drilling within a set of parameters driven both by the installations themselves (e.g. standard lengths of catenary) and the machine (stroke, drill head permutations etc.) to a survey of the tunnel segments we will have undertaken that show where “no drill” zones exist.
Each position could be solved by CAD but for the numbers of installations under consideration (>200,000) an analytical solution using equations is preferred. Hence we need a computer program that can manage all these inputs – preferably written by a person or persons with some level of geospatial appreciation.
The timescales involve surveys commencing in June and the first drilling information being resolved by end of August. The surveys and calculations will continue until this time next year.
If you are interested in partnering with us in some way to develop the approach and software we need could you let me know at your earliest convenience.
