Precise coordination for the motorway in German with the highest traffc frequency
The Oevermann Corporation was awarded contracts within the contractor consortium, for the reconstruction of the highway surfaces of the A 100 motorway, between the junctions: Kurfuerstendamm and Schmargendorf, as well as at the Schmargendorf motorway junction in Berlin. In the course of the construction works in 6 constructional sections, dependent on the condition of the original highway surface, the highway surface was renovated with a surfacing gauge of 3.5 cm (poured mastic asphalt) on constructional sections) and 14 – 33 cm (highway route). Included was a noise-reducing cover layering of ‘DSH-V 5’ in a gauge of 2 cm.
The road traffic, which normally circulated on the three-lane A 100 motorway had to be reduced to one lane during the construction works, which had to be initiated for traffic reasons during the summer holidays. Becaue of its significance as the motorway with the highest frequency of road traffic in the whole of Germany, extremely time close execution time periods for the various constructional stages had to be agreed.
This therefore involved for the excavatjon work and multi-surface renovated surfacings, the laying down of between around 3,500 tonnes to 12,000 tonnes of asphalt per constructional section, covered by the contract works on the contractual basis of seven days per week throughout. For purposes of controlling the works’ progress, a building construction rundown plan was required on the basis of hourly precision working, which had to be continuousl updated to cordiante the various individual works (especially the grinding services, roller laid asphalt and poured mastic asphalt.
For reasons of such detailed rundown planning, all building-constructional sections had to be executed in the course of multi-shift operations. In the ‘larger’ building-constructional sections, a second contractor had to be engaged, so that parallel working could be undertaken to accelerate completion.
The total 6 sections oft he contract works had to be completed with a short contractual time period.© PORR Oevermann GmbH
