The subject of performance of this contract is the removal of old environmental burdens in the area of First Brno Engineering Velka Bites, as (hereinafter "PBS Velka Bites"). The goal of remediation is to remove the contamination of soil and groundwater by chlorinated aliphatic hydrocarbons, and so that was factually and, in time fulfilled remedial measures, given the above decisions CEI and CEI RI Brno RI Brod. The subject of the public contract includes the following scope of work: - design and legislative preparations (implementing the rehabilitation, static report, a mathematical model of groundwater flow) - Implementation of the ancillary activities (drilling and other technical work - Application drilling, indication-remediation wells, infiltration wells, monitoring wells - a total of 1,097 linear meters, slug tests, geophysical measurements), - test operation rehabilitation - method ISCO + additional remediation pumping (1 year) - the actual operation of remediation - ISCO + remediation pumping (2 years) - remediation monitoring (ongoing ) - post-remedial monitoring (22 months) - liquidation of boreholes according to the project - redevelopment final report, final report postsanačního monitoring - CSDS database performance.
Replacement originally projected in situ chemical oxidation using potassium permanganate in the remediation of the geological environment by using ISCO peroxidisulphate solution. To change the method occurs as a result of new facts in the context of the opening round of groundwater monitoring and verification arrangement during a sewerage system in the area of interest. Change value is 42%. With this change is not linked to a price increase, the price of the original and new agents remains the same.
The subject of public procurement is to determine the carrying capacity of the bridge and the appreciation of the construction elements, in terms of feasibility, usability, durability or any intervention.
The subject of public procurement is to determine the carrying capacity of the bridge and the appreciation of the construction elements, in terms of feasibility, usability, durability or any intervention. The Contractor shall perform:
1. A static test arc portions of the bridge (5 fields), focusing on the deflection at the top of the arch and deformed joints.
2. Dynamic test arc portions of the bridge (3 selected field) in order to obtain data for analysis model.
3. Focus actual shape of the bridge structure incl. 3D scanning and then creates a condition survey of the bridge.
4. Installation temperature sensors then will continuously measure the temperature in the cross section of the structure after 12 months in order to verify the static behavior of the bridge.
5. Linear and nonlinear model arch, frame structures in order to determine load capacity of the construction elements.
6th pits, drill and chemical analysis to identify the characteristics of concrete and other materials (strength, water absorption, modulus of elasticity, thickness. Carbonation, macrostructure, hardiness, presence of ASR, the presence of salts). 7.Na the above materials (1-6 points) assessment of individual structural elements of the bridge in order to determine their applicability, durability and repair options.
