We are FCC Nº21

This is how the work on the redevelopment of the Nudo Norte is progressing. exhaustive programming will be very necessary, and where the final docu - mentation to be presented will also be rigorously taken into account. To this end, communication between the agents involved will be very important and all the information must come from a single reliable and coherent source. FCC takes advantage of BIM tools during the construction process to resolve the interferences generated with the new structures planned and the existing services affected by the work, as well as the capture of these and the layout of the work using laser scanners and photogrammetry for the use of point clouds in the definitions of the solutions. FCC also makes use of the benefits of digitising the work to obtain measurements and certifi - cations in a more orderly and efficient way, and incorporating 4D planning elements so that the technical moni- toring of the work can benefit from the digital model of the project. Improved air quality Analyses and studies carried out by the Madrid City Council’s Environ- ment and Mobility Department have determined that, prior to the start of the works, it took an average of 3.16 minutes for a car to cross the Nudo Norte. The use of BIM technology will indirectly contribute to reducing this time by 31% of private vehicle journeys during peak hours when the works are completed, which means a total of 3,667 hours per day if we take into account the 270,000 vehicles that pass through the area every day. This new situation will be made pos- sible by increasing capacity at critical points and eliminating junctions. On the other hand, the remodelling works at the Nudo Norte, with the consequent removal of junctions and the increase in capacity at critical points, will also bring about a very positive change in air pollution levels, as CO 2 emissions will also fall by around 14 tonnes per day, i.e. by less than 70%. This figure also reflects the motivation of Madrid City Coun- cil on this issue, complying with the air quality limits set by the European Union, which in turn reflect the mea - sures established by the city council in its Madrid 360 Environmental Sus- tainability Strategy. Until now, Nudo Norte was none other than the confluence of the M-30 and the M-607, the Paseo de la Castellana, the M-11 and the A-1. In fact, the convergence of all these roads between this junction and the Manoteras interchange has been one of the busiest stretches of road in Spain for many years. Once the remodelling works are completed, the results will be easily noticeable, especially for the almost 34,000 ve- hicles that circulate during rush hour (from 8 to 9 am) and the 33,800 that circulate from 6 to 7 pm. The effect of the works on the road junction will be felt in all its connec- tions, which in turn will have a positi- ve impact on the rest of the city. The four braided roads will be eliminated, after being the main cause of major traffic jams in this enclave, and will be replaced by three subways, at diffe - rent levels, and one overpass, which will connect the M-607 with Paseo de la Castellana. Roads will also be rearranged and some existing roads will be adapted and widened to the new context with the same aim: to in- crease the capacity of the roads, im- prove road safety and accessibility to public transport and existing services, thus reducing journey times.
