Querying a regulatory model for compliant building design audit

The ingredients for an effective automated audit of a building design include a BIM model containing the design information, an electronic regulatory knowledge model, and a practical method of processing these computerised representations. There have been numerous approaches to computer-aided compliance audit in the AEC/FM domain over the last four decades, but none has yet evolved into a practical solution. One reason is that they have all been isolated attempts that lack any form of standardisation. The current research project therefore focuses on using an open standard regulatory knowledge and BIM representations in conjunction with open standard executable compliant design workflows to automate the compliance audit process. This paper provides an overview of different approaches to access information from a regulatory model representation. The paper then describes the use of a purpose-built high-level domain specific query language to extract regulatory information as part of the effort to automate manual design procedures for compliance audit

Automated generation of SPARQL queries from semantic mark-up

Previous work has shown that semantic mark-up of normative documents can be consumed directly by a rule-engine or can be automatically transformed to a number of existing rule representations. This work investigates the feasibility of automatically transforming examples of normative documents into SPARQL and testing the result against typical building information models. The desirability of using SPARQL is discussed

Improving productivity by the automation of checking of 3D parametric modelling

The development of object-based 3D modelling based on Industry Foundation Class (IFC) has given rise to the possibility of computer-based interpretable models and the automation of checking based on rules. Past studies suggest that professionals within the industry have low confidence in the quality of design data, and consequently, there is an over-reliance on manual checking. This study aims to examine the application of automatic checking in industry and opportunities to improve productivity by automation. It identifies a means to improve the quality of data and available checking software, albeit with poor interoperability. The study indicates a quality system that can be applied to the generation of checking rules and a method to improve productivity of automatic checking by using the principles of Dataflow

Modelling and accessing regulatory knowledge for computer-assisted compliance audit

The ingredients for an effective automated audit of a building design include a building model containing the design information, a computerised regulatory knowledge model, and a practical method of processing these computable representations. There have been numerous approaches to computer-aided compliance audit in the AEC/FM domain over the last four decades, but none has yet evolved into a practical solution. One reason is that they have all been isolated attempts that lack any form of industry-wide standardisation. The current research project, therefore, focuses on investigating the use of the industry standard building information model and the adoption of open standard legal knowledge interchange and executable workflow models for automating conventional compliant design processes. This paper provides a non-exhaustive overview of common approaches to model and access regulatory knowledge for a compliance audit. The strengths and weaknesses of two comparative open standard knowledge representation approaches are discussed using an example regulatory document

Capabilities of rule representations for automated compliance checking in healthcare buildings

A suitable rule representation is essential to enable automated compliance checking of building design. It encapsulates engineering knowledge and facilitates an adequate interpretation of design standards. However, existing methods have achieved limited capabilities to represent rules for automated compliance checking. Thus, they merely worked for limited types of rules. This paper aims to identify capabilities needed for rule representation by using healthcare design regulations as an example. It can serve as a foundation for developing rule engines and compliance-checking systems in the future. A four-step process was used to systematically analyse six healthcare building regulations in rule-oriented and implementation aspects. The results showed 18 capabilities for healthcare rule representation, where 16 are required, and two are desirable. This research is valuable to researchers and practitioners by providing a checklist for future representation development and criteria for assessing rule representation methods

An automated building information modelling-based compliance checking system for Malaysian building by-laws fire regulations

The implementation of Building Information Modelling (BIM) in the Architecture, Engineering and Construction (AEC) industry has significantly amplified the responsibility of designers in creating reliable and accurate BIM models. Fundamentally, the BIM models must comply with the fire safety regulations to provide minimum protection for building occupants and property. Since fire safety regulations are known to be complex and rigid, the manual compliance checking process could lead to inaccuracies, especially in a BIM-based environment. Hence, this study developed an automated BIM-based fire regulations compliance checking system for Malaysian’s AEC industry. In order to establish the rules and BIM properties necessary for fire regulations compliance checking process, 256 clauses from Parts VII and VIII of Selangor Uniform Building (Amendment) (No. 2) By-Laws 2012 were selected to create a BIM model using Revit® based on two-dimensional drawings of a completed 17-storey institutional building. Three investigations were conducted to structure the representation of the rules and BIM properties. First, the fire safety clauses were formalised through a classification technique, semantic mark-up requirement, applicability, selection, exception (RASE) methodology, and interviewing two fire engineers and a representative from the Fire and Rescue Department Malaysia (JBPM). Secondly, the BIM properties consisting of 54 families and their respective parameters in Revit® were identified for the compliance checking process. Lastly, pseudocodes and architecture of the automated system were developed to establish the relationship between the formalised clauses and BIM properties. Dynamo® scripts were used to develop a prototype of an automated fire regulations compliance checking system which could automatically check for fire doors and staircases in Revit®. The representative from JBPM, three fire engineers and architect validated the proposed architecture while the prototype was validated by three architects, two structural engineers, one mechanical engineer, and two civil engineers. This study contributed to a semi-automated rule translation process which combined existing approaches in this field of study. The classification technique and semantic mark-up RASE methodology were refined in this research by developing flowcharts to provide specific guidelines in formalising the clauses. The semi-automated rule translation process encouraged the participation of relevant fire safety experts and provided more accessibility for designers compared to existing studies. This study also offered more practicality for designers to employ the system by utilising native BIM model data representation. High mean scores ranging from 4.00 to 4.96 were obtained for the validation process, which affirmed the feasibility of an automated BIM-based fire regulations compliance checking system to assist designers in the Malaysian AEC industry

BIM-based smart compliance checking to enhance environmental sustainability

The construction industry has been facing immense challenges to move towards more- sustainable buildings with minimum harm to the environment. The building design and construction process is conditioned by numerous sustainability regulations and assessment measures, to promote sustainable construction. These regulations are continuously expanding in their requirements, and incorporating a huge amount of data that needs to be rigorously dealt with, in order to check compliance and asses the performance Building Information Modelling (BIM) promotes the effective information and process integration across the building life-cycle and supply chain. This integration should comply with an increasingly-complex regulatory environment and statutory requirements. The aim of this thesis is to improve and facilitate the sustainability compliance checking process, by focusing on inter-operability between existing methods of compliance checking and building information modelling. This thesis presents a generic approach for BIM based compliance checking against standards and regulations, with a particular focus on sustainable design and procurement. To achieve this, a methodology has been developed to enable automated sustainability compliance checking. This involves (a) extracting regulatory requirements from sustainability-related regulations available in textual format; (b) converting these into BIM- compatible rules; (c) processing these rules through a dedicated rule-based service; and (d) performing regulatory compliance analysis underpinned by the concept of BIM. A semantic extension of the IFC (Industrial Foundation Classes) for sustainability compliance checking has been developed. The outcome of the research was implemented in the RegBIM project and is in the process of being exploited as an online service by industrial organization, the Building Research Establishment (BRE) in the UK
