What the buyer is looking for

In the case of acoustic evaluation of noise protection walls with height-dependent airborne sound insulation and heterogeneous material structure, the objective of noise protection walls (LSW) is to have a central meaning in traffic noise protection on federal highways. The technical requirements for LSW are regulated in the ZTV-ING Part 8.1. The performance defined therein is in fact only required in the lower wall area, since the upper wall area contributes only to a small extent to the overall effect of an LSW. A targeted waiver of high airborne sound insulation in the upper wall area would reduce material consumption and costs and could at the same time open up new design and design freedoms. In particular, it is open whether the model assumption of a complete shielding effect for LSW with reduced airborne sound insulation in the upper wall area used in the sound propagation calculation according to RLS-19 or BUB can be mapped there.

Tactics

When contracts were awarded in this country and sector, there was usually a single bid in the end. A solid bid has a real chance here. (Based on 3,769 completed awards — not a statement about this procedure.)

This procedure allows 36 days between publication and deadline — typical in this country is 32 (median of 20,496 procedures). Much more generous than usual — time for a thorough bid rather than a quick one.

Foreign bidders

In Germany · R&D services, 161 contracts went to foreign companies over the last 3 years (of 4,002 recorded awards) — mostly from Netherlands, Italy, Spain.
