RFI - Inquiry regarding provision of road survey equipment and related analysing software, technical description and delivery time for system
In the analysing software it should be possible to divide a road in sections based on rut depth or area of defined ruts depth as well as other factors collected in a survey. The surveying system should identify all potentially dangerous objects within the clear zone, some 10 – 15 m of the shoulder edge.
The system shall include following:
1. Laser scanner
2. Ground penetration radar, GPR System
3. 3D accelerometer
4. Video cameras
5. Thermal camera
6. Analysing software
7. Implementation and training
Manufacturer could possess more detailed information than are in the description which we would appreciate to see and possible other alternatives. We would be pleased for information on additional features which you could provide together with the above described survey system.
Detailed information and estimation of possible delivery time of complete surveying equipment and analysing software offered and their capabilities in this purpose should be marked; 20526 RFI road survey equipment and sent by e-mail to: utbod@rikiskaup.is no later than 18th of March 2017.
More detailed description
Road survey equipment and related analysing software
1 Laser scanner for scanning the road shape and dimensions of the road surface and its surroundings. Monitoring deformations of the pavement structure shall be possible. System should also allow measurement of tunnel walls, pavement, rut depths, cross fall, ditch depths, verges, edge drops, etc. information on accuracy in x, y and z at 10 and 20 m from centreline of scanner is requested.
2 GPR System shall be complete with ground penetrating radar (GPR) system for collecting continuous data from pavement structure thickness, top layers and down to at least 5 m (could be two antennas), identify moisture content in road structures and locate objects such as boulders, culverts and pipes under the road. High frequency antenna should be air coupled and it should be able to calculate dielectric value of pavement surface.
3 3D accelerometer installed to the survey vehicle for complete IRI and acceleration survey.
4 Video cameras for inspection of the road and surrounding with the analysing software.
5 Thermal camera including case, mounted on vehicle.
6 Software for integrated analysis of all the above mentioned survey data, i.e. the pavement and surroundings. The system should allow measurement of pavements structure, rut depths, cross fall, ditch depths, verges, edge drops, location of road signs etc.
Software should be able to prepare GIS maps from survey of the roads and the roads surrounding area, all data shall be possible to be stored into a data bases. Software should be suitable to evaluate measured rut depth and analysing increase of rut depths over a period of time, analysing areas of ruts of given depths intervals divided in road sections, identifying and locating excess water in the road.
With the analysing software it should also possible to perform back calculation of FWD data using FWD deflection data and pavement structure thickness data from GPR.
7 Implementation and training in Iceland We would be pleased for information on additional features which you could provide together with the above described survey system.
