Summary
Machine-generated summaryRijkswaterstaat is procuring a framework agreement for dredging works on the Lemmer-Delfzijl main waterway in the Northern Netherlands. The scope covers freshwater dredging maintenance and removal of bottlenecks, re-dredging of acute shallows and erosion holes in the fairway, placing freed clay at large erosion holes that could endanger sheet pile walls by undermining, and removal of known car wrecks and other large obstructions. About 40 urgent bottlenecks totalling roughly 100,000 m3 are defined, plus 27,000 m3 regular annual dredging; the indicative estimate is EUR 10,000,000. Annual needs are agreed in a further agreement.
