Inspection of the gravity sewage, sanitary and combined sewage network covering the catchment area of the Right-Bank Collector I in the city of Poznań. Engineering research.

The subject of the Contract is a service consisting in the inspection of the gravity sanitary and combined sewage network with a TV camera – Scope (A, B, C, D) covering the catchment area of the Right Bank Collector I in the city of Poznań with a total length of 54,990.18 m.

Activities and auxiliary works for the purposes of TV Network inspections as part of the Subject of the Contract:

1. Cleaning the Network of accumulated sludge (constituting waste) and other waste to a condition that allows for TV inspection. The Ordering Party allows for the possibility of TV inspection when the channel is filled not exceeding 30%, and in the case of channels above DN500 not exceeding 50% of the filling height. Cleaning consists in the permanent removal of sludge (constituting waste) and other waste from the Network. It is not allowed to push/flush sludge and other waste to further sections of the Network. For sections of the Network sealed with sleeves, an appropriate hydrodynamic cleaning pressure not exceeding 60 bar should be applied.

2. Loading and transporting the collected sludge and other waste from the place of their production and tidying up the work site (restoration to the original state). Waste should be handed over for management to an authorized entity with valid permits required by law from the competent authority in the field of waste management.

3. Securing the place where the work is performed with appropriate signage and traffic organization that meets the conditions contained in the applicable law in this area. If it is necessary to occupy a road right-of-way, it is required to obtain a consent in the form of a decision from road administrators to occupy the right-of-way for the duration of works in the right-of-way and to bear the costs and consequences of their occupation and marking. Completion of works in the right-of-way requires obtaining a protocol acceptance from the road administrator. In the case of carrying out works outside the right-of-way, it is required to obtain a permit from the administrators of the area in question. If it is not possible to enter the area, the event should be reported to the Contracting Authority by presenting the refusal of the administrator/owner of the area in writing. A reduction in the scope covered by the Agreement in this respect may not result in financial claims of the Contractor against the Contracting Authority.

4. Ensuring the continuity of sewage collection and transmission during the works (if necessary, by-passing).

5. Preparation and submission of documentation concerning the performance of the Agreement to the Contracting Authority.
