The Redzone MSI (Multi-Sensor Inspection) platform offers a comprehensive solution for pipe assessment. This innovative system integrates laser/sonar technology with CCTV and NASSCO scoring, presenting results in an intuitive 3D format. The platform provides detailed topographic mapping of pipe radial variances, as well as corrosion and debris mapping, including depth and quantity measurements from start to end. Its flat graph report format allows for precise analysis of radial deviations, while multi-mapping features enable instant access to whole pipe views, 3D presentations, and accurate identification of points of interest. The MSI platform facilitates thorough and efficient pipe evaluation therefore this is the platform we are requesting.
4. Can you please post the prevailing wage determination sheet so we are all bidding with the same sheet? Please refer to the wage rate information beginning on page 30 of the bid package.
5. What is the size of the manhole openings in this system? The manhole openings will either be a 24” or a 32”.
6. How deep is the pipe in this system? It will vary depending on the grade of the landscape, but the few that were checked were about 19’ – 20’ deep.
