Public tender Vob/a drilling work (DIN 18 301); work to expand boreholes (DIN 18 302); construction of groundwater measuring points on the site of the Major-Karl-Plagge barracks. Soil contamination with Pfas was detected in the area of a fire training house and in the area of the fire station. Additional tests are to be carried out to check whether the pollutants have already reached the groundwater approx. 15 to 20 meters below the ground. The area on which the construction site is located is fenced in and partially sealed off by buildings and driveways. Other uses will take place on the site while the work is taking place. As part of the current investigation phase, the installation of two groundwater measuring points on the barracks site is planned (single measuring points). 4-hour short pumping tests are to be carried out at the groundwater measuring points to be set up. The site of the Major Karl Plagge barracks is a military security area. Personnel and vehicles must be registered to enter the site. Daily working hours are limited to 7 a.m. to 4 p.m. The current list of services includes drilling and expansion work, rinsing and carrying out the pumping tests. Creating 2 single measuring points, final depth approx. 25 m U. Gok. Carrying out two 4-hour short pumping tests. A DVGW certificate in accordance with DVGW worksheet W 120 is to be submitted with the offer.

Multi-building automation (din 18 386); New weather radar tower Jesberg Jt / November 14, 2024 Project: A.0454.190502 04 00 480 Building automation Automation systems - Automation device including control device - Approx. 50 physical input / output functions - Approx. 40 common input / output functions - Data interfaces for Bacnet / IP, Modbus RTU and M-bus - Binary / analog and Modbus RTU measured value converters - Approx. 5 sensors Control cabinets - Control cabinet including all installations for accommodating the automation focus Management and operating devices - Configuration of management and operating functions for the data points listed above - Training of operating personnel Cables, lines, laying systems - Existing laying system on site - Extension of the laying system for connecting Ga components - Cable pulling indoors and outdoors Building automation, other - Accompanying acceptances - Trial operation for two weeks 480 Building automation for the facilities of the technical building equipment (tga) Building automation (GA) is planned. The system is fully connected to the management and operating level (MBE) of the Offenbach property. A tiered system is created, consisting of: - connection to the MBE (CAT connection to the network cabinet) - automation level (switch cabinet including power unit and automation unit in the operating room) - field level (sensors, contacts, etc.) The GA ensures the complex processing depth for all measurement, control, regulation, monitoring and optimization functions. The TGA is operated from the MBE via the automation schemes. All process data from the field level is available in the MBE and operations are managed from here. The GA ensures: - Economical and optimal regulation and control of all TGA facilities - Central operating hour counting - Central limit value monitoring - Cross-system energy optimization through central energy management - Minimization of maintenance effort - Fault and event statistics - Relief for specialist personnel 481 Automation facilities An automation focus (ASP) is created in the operating room. The ASP contains the following systems: - Heat supply system - Air conditioning systems - High-voltage systems - Hazard detection and alarm system - Conveyor system All GA-relevant TGA facilities in the building are listed in the GA function list. The number of ASP data points is also listed. The necessary data points are determined using the automation diagrams and the data point list in accordance with VDI 3814. The required functions arise from the TGA requirements. 482 Control cabinets The control cabinet consists of a power section and an automation section. The power section contains the voltage supply for the ASP and all field devices. Safety-relevant devices for which redundancy is required due to safety regulations are not provided. The performance characteristics of the control cabinet are determined according to the requirements of the TGA. 483 Automation management The transmission devices to the management level are determined according to the requirements of the TGA. The automation level is connected entirely to the existing management level of the Justus Liebig University and this is expanded accordingly. 483 Cables, lines and laying systems The cables are laid on existing cable routes with a separator for separate laying of high-voltage and measuring or signaling lines, as well as in heat-resistant protective pipes in the area of heat-conducting installations. An overvoltage protection device is provided in the measuring line for the outside temperature sensor.
