“…3D Repo [Doboš and Steed 2012] is an open source design coordination system specifically developed for the AEC industry. Over the years, the platform evolved from an early XML3D-based [Sons et al 2010] visualization and data hosting prototype [Doboš et al 2013] into a commercially viable offering 3drepo.io [Scully et al 2015] based on X3DOM [Behr et al 2009] and later Unity 3D game engine [Friston et al 2017]. The latest iteration includes 3D Diff [Doboš et al 2018a] which detects real-time differences between any two 3D models regardless of their underlying file type directly on a web browser.…”

“…1 can consist of hundreds of thousands of components. Various techniques including but not limited to geometry simplification [Limper 2018;Limper et al 2016], mesh batching [Scully et al 2015] and streaming Schilling et al 2016;Scully et al 2016] have been deployed to support complicated models on web browsers. Yet, despite all this added complexity and the limitations of WebGL, the users of such systems still expect functionality similar to desktop authoring tools.…”

Figure 1: User-driven rectangular selection on a model with 75k components within the 3D Repo cloud platform. a) The user draws a rectangle to indicate the desired selection volume. b) The system performs intersection calculations in real-time and displays the selected objects with an "X-ray" highlighting. c) The user hides the selection and the state change is reflected in the component tree.

The Architecture Engineering and Construction sector is currently undergoing a significant period of change and modernisation. In the United Kingdom (UK) in particular this is driven by the government's objective of reducing the cost of construction projects. This is to be achieved by requiring all publicly funded projects to utilise fully collaborative Building Information Modelling by 2016. A common goal in increasing the Building Information Model (BIM) adoption of the industry is the movement towards the realisation of a BIM as either a single data model or a series of tightly coupled federated models. However, there are key obstacles to be overcome including; uncertainty over data ownership, concerns relating the security/privacy of data and reluctance of companies to "outsource" their data storage. This paper proposes a framework that is able to provide a solution for managing collaboration in the Architecture Engineering an Construction (AEC) sector. The solution presented in this paper provides an overlay that automatically federates and governs distributed BIM data. The use of this overlay provides an integrated BIM model that is physically distributed across the stakeholders within a construction project. The key research question addressed by this paper is whether such an overlay can, by providing dynamic federation and governance of BIM data, overcome some key obstacles to BIM adoption including questions over data ownership, the security/privacy of data and reluctance of companies to share data. More specifically, this paper provides the following contributions: (i) presentation of a vi-1 sion for the implementation and governance of a federated distributed BIM data model, (ii) description of the BIM process and governance model that underpins the approach and (iii) provision of a validation case study using real construction data from a UK highways project, demonstrating that both the federated BIM overlay and the process and governance model are fit for purpose.

Georeferenced 3D models are an increasingly common choice to store and display urban data in many application areas. CityGML is an open and standardized data model, and exchange format that provides common semantics for 3D city entities and their relations and one of the most common options for this kind of information. Currently, creating and maintaining CityGML models is costly and difficult. This is in part because both the creation of the geometries and the semantic annotation can be complex processes that require at least some manual work. In fact, many publicly available CityGML models have errors. This paper proposes a method to facilitate the regular maintenance of correct city models in CityGML. This method is based on the continuous deployment strategy and tools used in software development, but adapted to the problem of creating, maintaining and deploying CityGML models, even when several people are working on them at the same time. The method requires designing and implementing CityGML deployment pipelines. These pipelines are automatic implementations of the process of building, testing and deploying CityGML models. These pipelines must be run by the maintainers of the models when they make changes that are intended to be shared with others. The pipelines execute increasingly complex automatic tests in order to detect errors as soon as possible, and can even automate the deployment step, where the CityGML models are made available to their end users. In order to demonstrate the feasibility of this method, and as an example of its application, a CityGML deployment pipeline has been developed for an example scenario where three actors maintain the same city model. This scenario is representative of the kind of problems that this method intends to solve, and it is based on real work in progress. The main benefits of this method are the automation of model testing, every change to the model is tested in a repeatable way; the automation of the model deployment, every change to the model can reach its end users as fast as possible; the systematic approach to integrating changes made by different people working together on the models, including the possibility of keeping parallel versions with a common core; an automatic record of every change made to the models (who did what and when) and the possibility of undoing some of those changes at any time.
