Framework agreement on wind tunnel experiment.
The Norwegian Public Roads Administration (SVV) has been tasked with investigating technical solutions to replace all ferry services on E39 with fixed connections. Wind and wind power assessments are a significant part of the design work. It is therefore necessary to carry out experiments in a wind tunnel.
Framework agreements with be signed with three tenderers in each sub-contract.
The qualification requirements that apply to all of the sub-contracts.
The Norwegian Public Roads Administration"s project Ferry Free E39 outside of the Western Region has the option to join the agreement to cover remaining stretches of the project on verbatim terms. The project outside of the Western Region is free to utilise the option, or execute their own procurements on equivalent deliveries outside of the Western Region.
Other Norwegian Public Roads Administration projects have the option to join the framework agreement on verbatim terms. They are free to trigger the option or to conduct their own procurements for similar deliveries.
Sub-contract 1. Testing of small scale models.
Testing of section models, including testing of vortex shedding requires a wind tunnel that has a test area with a minimum cross sectional area of 2.0 m wide and 2.4 m high. The maximum requirement for the wind tunnel is 8.0 m wide.
The laboratory facilities should be ready to execute section model testing to determine: Statistical load co-efficiencies, vortex shedding, instability limit (speed limit for flutter), aerodynamically derived (Scanlan type) and aerodynamic admittance functions.
Documents demonstrating that the tenderer has fulfilled the minimum requirements.
Sub-contract 2. Testing of large scale models.
Planning, preparation and testing of aeroelastic complete bridge model to identify vortex shedding of the bridge slab, buffeting response and verification of flutter wind speed. It may also be relevant to test topography to identify average wind flow and turbulence intensities. These tests require a wind tunnel that has a testing area with the minimum dimensions 11.0 m (wide) x 11.0 m (length) x 2.5 m (height).
