Quotation Are Invited For Supply Of Sewer Hydraulic Modelling Software

Quotation are invited for Supply of Sewer Hydraulic Modelling Software. Deadline: 1-Apr-25 1 Sewer (Gravity network) Hydraulic modelling and conceptual planning package Utilising the node/link network database generated by package 2, be able to do the analysis and determination of all engineering parameters, then enabling optimal design of sewer drainage or other gravity network systems, including automatic optimisation of pipe sizes for planning. X 5 It should use the theory of contributor hydrographs for analysis and time-lag routing in order to determine the spare capacities in sewer systems, taking cognisance of the land use water demand vs sewage discharge relationship, infiltration and leakage. It uses either the Annual Average Daily Demand (AADD) or Unit hydrograph peak inflow method. Must be able to cater for the range of infrastructure features namely pumps, gravity pipes, siphons, valves, chambers, surcharge ponds, diversion structures or manholes. For Analysis and design modules it must utilise the Contributor Hydrograph Theory hydraulic network engine, making use of pipe invert levels where these are known or pipe slopes where they are not. A key benefit of this engine is that invert levels are not required for all manholes. Optionally, parts of a sewer system where invert levels are available, can be analysed using the builtin EPASWMM analyses engine. Must be able to directly read or easily convert (without loss of any data elements) the equivalent SEWSAN data files of specialist Software currently in use. CAD and GIS platform built for working with large amounts of data fast and easily. Utilise sophisticated database wrapping techniques to provide flexibility and compatibility with workflow as for editing a spreadsheet. Must expose all the functions of the CAD/GIS engine to its power users. it must allow very fast processing of very large model datasets, automated GIS feature error location and correction (e.g. duplicate lines, misclosures) as well as generic. GIS datasets in the GIS environment compatible with ESRITM Shapefiles as well as supporting the loading of detailed CAD background drawings compatible with the AutoCADTM DWG format. Models, GIS and CAD should work with the various South African old and new survey coordinate projection systems. In terms of data processing, the transition from CAD to GIS must be very fluid and support the workflow of most engineering-related projects. In terms of data integration, this tool must support the loading of large Digital Terrain Model (DTM) point files for building a 3D mesh for rendering contours or interpolating elevations of model elements such as manhole levels. It must be able to accurately underlay geo-located aerial photography images in major industry-standard formats including JPG, TIFF, BMP and Google MapsTM (or similar) to trace against or inform vector layers above. Even if the package uses its own proprietary files format, full compatibility must be guaranteed via import/export of abovementioned GIS, CAD or DTM file formats. The current specialist integrated master planning software is written in several languages in order to link up with infrastructure and web-based components of the software which are Microsoft C++, HTML5 and JavaScript. The remaining engineering components of has been written in Embarcadero Delphi RAD Studio. 2 Architecture CAD/GIS functions X5 The Module above should run on WindowsTM platform for standalone desktop environment or as server thick client. All modules need to be able to make use of the same AutoCADTM-compatible CAD. ESRITM-compatible GIS, SQLTM databases and ExcelTM-compatible data table structures. In addition, a user-friendly SQL query builder able to operate on multiple layers and databases, building relational database views, that allows the system user to perform any further queries on the data that may be required. Data integration with several SQL database format should be guaranteed. Must be able to export SQLTM and Shapefile or SpatialLiteTM datasets to a query tool for spatial rendering. 3 Functionality to Export to IMQS8 (Information Management Query Software) The IMQS Water Infrastructure Module is a web-based, viewing tool that is used for Planning and operations management of the CoJs Hydraulic System. The module integrates with specialist hydraulic software packages and curates information to offer a geographically linked, infrastructure-lifecycle focused representation of a municipalitys water/sewer reticulation network. For only one of the Five (5) licences, the service provider is required to develop a functionality within the Pipe Replacement Prioritisation that will enable the Johannesburg Water-Planning Networks to export data/information from the Sewer hydraulic modelling Software into IMQS8. The exported reports may be done in the form of alphanumeric reports, graphs, and GIS type maps. The information that is exported into IMQS8 from the sewer Hydraulic modelling Software includes: a). Hydraulic Information i.e. pipe diameters, velocities, relative and absolute spare capacities, etc. b) Asset Information i.e. pipe diameters, material age, performance, replacement value etc. c) Master planning information (future diameters, future velocities, etc. Water demand management information (i.e. land use, zoning, AADDs, etc Data import formats shall include ERSI shape files, CSV text files and KML Tender Link : https://www.johannesburgwater.co.za/scm/supply-chain/request-for-quotations/open-rfq-2/
