Ordnance Survey Linked Data

The Ordnance Survey is Great Britains national mapping agency, providing the most accurate and up-to-date geographic data, relied on by government, business and individuals.

OS OpenData is the opening up of Ordnance Survey data as part of the drive to increase innovation and support the “Making Public Data Public” initiative. As part of this initiative Ordnance Survey has published a number of its products as Linked Data.

This dataset combines three separate linked data resources: the 1:50 000 Scale GazetteerCode-Point Open and the administrative geography gazetteer for Great Britain.

Revit Tip – Creating quick 3D sections & floorplans – Graitec Blog

Like many other functions in Revit, there is more than one way to create sectioned 3D views. The way we will look at here uses the view extents from existing 2D views such as sections and plan views to set what is visible in the 3D section, which is a far more controlled way of setting the views up than just activating the section box and moving the shape handles. Just follow the instructions below to get started:

So that you don’t override your default view, create duplicate 3D views and rename them to suit. For a 3D section view ensure that you have created a 2D section and set its extents to show exactly what you want to see in your 3D section. If you are using a floorplan or ceiling plan, then it is mainly the view range that sets the location of the section box. Scope boxes and crop regions will also have a bearing on this.

Open the 3D view you wish to use and right click on the view cube; on the menu you will see the option ‘Orient to View’, which will expand to display the four options shown below. In this case we will select Sections. This will then give you a list of your building sections, and if you look below you can see that some are named and some are not. It is good practise to properly name views that you wish to keep and use for such cases.

Working towards a joined-up approach to BIM | BIM+

A working group of the UK BIM Alliance set up to help make the process of sharing product data simpler and more standardised will publish its first report at Digital Construction Week later this month. We speak to the group’s chair Su Butcher to learn more about the process.

Talk us through a bit of the background and what the group is trying to achieve?

Skosmos: BUILDVOC – Thesaurus for the built environment

Building Information Modelling Management (BIMM) is at the forefront of this vocabulary, giving users a reliable source of definitions and concepts.

These terms will be used to promote consistency, efficiency in the built environment. Which will be used for data exchanges, file naming of structured and unstructured data during the lifecycle of buildings.

Health and Safety File Naming Tool Kit for Documents / Drawings under construction design management (CDM) a health and safety file, in which information produced during the development stages, is stored for future works for managing residual risks.

Information contained

  • as built documents→vendors, consultants, client
  • as built drawings → consultants, contractors, suppliers
  • information about products→manufactories

The naming convention tool will aid originators of this information to format the file names in a consistent manner, the outcome is to structure the files for search, and data exchange using a controlled vocabulary with Microsoft excel.

PwC BIM Benefits Methodology and Report — Centre for Digital Built Britain

To evaluate the actual impact BIM deployment has on asset planning, delivery and operation, PwC were commissioned to develop a BIM Benefits Measurement Methodology (BMM). The BMM sets out a measurement rational and model, whilst the Application Report tests deployment of the BMM on projects that have used BIM in their delivery. As well as providing a methodology for measuring benefits, the BMM Benefits Framework is intended help to define potential BIM benefits from the project outset, following industry plan of work stages. The BMM and associated Report documents are available below.

Graph + Linked Data for document retrieval

The following graph, represents a number of months of work combining the following:
-eprints document repository with ontology plugin (to import ‘subjects’ from external sources)
-sparql endpoint for the relationships to be stored in linked rdf format
-linked open graph which gives the ability to navigate the documents by subject, and other relationships
In the following months I will be writing about how you might be able to use link data in your business, this will focused on the construction sector, but the principles are the same.

Linked data LDAC 2018

Great workshops today at the linked data conference in London at LCU, reviewed some outstanding research into how BIM and linked / structure data could be used together, one of my favourites was from Cardiff university looking how structured sparql queries could assist in reviewing building regulations compliance. Which the construction industry needs tools like this to connect “design” to the real world i.e law.
