Barnes named the company Auto-trol as a shortened version of automated control, which he had given to a product he developed in the s. Inputs commands were done with an electronic light pen while at General Motors Research Laboratories in the s, Dr. Hanratty was a co-designer of DAC Design Automated by Computer , the first production interactive graphics manufacturing system. CAD chronology: before , Models based on 3D solid modelling was first developed in the late s.
Parametric modelling emerged from an extension of B-rep and CSG technologies and a mixture university research and intense industrial development in the s. Page 13 Figure 2. Kymmell, Creation of building and spaces is a continuing process of assimilating, modifying and reinventing bases of practical building knowledge.
Miller, Shoshkes states design solution needs to respond to Page 14 various aspects of building, both intangibility of ideas as well as tangibility of human, environment and technical reality. The design process is an evolution of the interactions of people, events, problems, ideas and images, contains certain mystique and so hard to explain and to describe the exact moments.
This managing information known, unknown, return to known connects to the description of the architect as a composer by Architect Robert Geddes who explains acts of design as a collaborative orchestrated efforts with innovation, imagination and creativity and emphasizes on design decisions as the key to successful projects but renders importance on the design of the processes involving the intervals of the projects and shared understanding of the vocabulary to profit on collective actions which guide the design process Shoshkes, The practice constructed structures on site which he compared with a painter receiving instant feedback for the artwork and thus extended design process to the site.
Scott Johnson ran a research driven practice and assessed and interpreted knowns into programming and selected a set of values to process the acquired knowledge into design by sketching, drawing or modelling. He declined to any conscious design process to generate design rather stated quick drawing to generate idea as a method.
Szalapaj commented on processing the known and unknown information in digital format as a cyclic process: changed interactions and particular prominences of design criteria Page 15 require continual cyclical process of model generation irrespective of the priorities of criteria in different phases.
It is to mention that the standard project phases typically consist of planning, programming, schematic design, design development, contract documentation and contract administration. Shoshkes, Information acquired, produced or generated in various phases are processed differently while designing in traditional process or in BIM process.
Azhar et al. BIM process is integrative and collaborative that increases accuracy and efficiency in design with optimized design quality, aesthetics, constructability, affordability, timeliness and seamless flow into lifecycle management while traditional process is more linear Azhar, et al. Figure 2. Page 16 Figure 2. Gaps of knowledge while shifting from traditional to BIM process might raise some operational project issues.
Analysis requires intense collaboration among team members of specialists which can be effectively generated by mix of configurable tools.
Construction level information is still outputted by drawings but in future practice, BIM model itself can serve as the legal basis for construction documentation. Design and construction integration can easily be processed by BIM as a collaboration facilitator to provide benefits of early identification of long lead-times and shorten procurement process, value engineering as design proceeds, early exploration and setting of design constraints related construction issues, facilitating identification of the interaction, reducing differences between designed construction model and manufactured model, significantly shortened cycle times for fabrication detailing.
Decision trees, regulation management, families of related codes, question and answer user interface were some of developing methods to address those issues. Manual methods of building code check require analysis of presented building information, counterchecks of references and output results against building codes by designers and so has an increasing possibility of making mistakes during the process of code compliance checking. Industry contributions and academic research have responded to the issues.
An institutional approach to accommodate automatic code check was introduces in by Singapore building officials considering code checking on two dimensional drawings which evolved to CORENET in working with IFC industry foundation classes building models Nawari, There have been other intensive research and dedicative efforts made to facilitate automatic code compliance check.
The field of rule checking is only emerging Eastman et al, Eastman et al has articulated automatic code checking process in four different stages: Rule interpretation, Building model preparation, Rule execution and Rule check reporting; to evaluate case studies of Automatic code compliance check. Rule interpretation is a logic-based method that interprets from natural language to process able form of machine language using a predicate logic which is well defined and can be evaluated as true or false.
Ontology of names and properties translate rules onto context and properties in which the rules apply. Implementation method tests contextual condition using computer language encoded rules and parametric tables. Language driven is a longer term rule implementation method that has been envisioned as predicate logic-based or domain oriented. Page 19 Building model preparations require adjustment to model views, derive implicit properties using enhanced objects, and derive new models, performance-based model and integrated analysis, Visibility of layout rule parameters.
Model views might require purging of unnecessary data and to include necessary details for code checking. Deriving implicit properties using enhanced objects responses issues of insufficient information in the models by precluding them in the object oriented programming principles. Deriving new models require other efforts to prepare the model for code check. Visibility of layout rule parameters on a drawing are assessed with instances of some type of layout requiring filtering of redundant graphic checking.
Rule execution phase brings together the prepared building model with rules that apply to it which can be performed by model view syntactic pre-checking and management of view submissions. Model view syntactic pre-checking simplify rule execution by checking the rules have been interpreted into computable forms consistent with functions.
These functions have been prepared to match the capabilities and information in the building model. Management of view submissions is required to manage the completeness of rule checking and model version consistency. Rule check reports are rule instances graphical reporting and reference to source rule. Rule instances graphical reporting represents the outcome of the check in a graphic format.
Reference to source rule can report much effectively outcome with references to the specific rule. The table is much explanatory of the overview of currently available rule checking systems. Page 20 Figure 2. Eastman Page 21 Figure 2. Eastman Page 22 Figure 2. Courtesy Tan. Page 23 Figure 2. Courtesy Ding. Page 24 Figure 2. Courtesy Ding Page 25 Figure 2. Courtesy Wastman Figure 2. Nawari has proposed a cyclic process in which automatic code checking in building design is integrated in the design process.
Courtesy Eastman. Eastman et al presented auto code checking process that mostly deals with post facto application of rules. A cyclic code check evaluation applied during and supporting design development might be utilized to check every design move and would allow immediate identification of the action violating a rule to facilitate corrections.
If the corrections are not made when an error first occurs, then this association of the design action and the rule violations should be saved for later management for correction to a design.
Page 27 2. In theory, automatic code compliance check is achievable utilizing BIM applications. There are areas of automatic code compliance check using BIM applications need to be addressed. There are not many examples of fully functional automatic code compliance checking applications. It is accepted that BIM as a design tool and a process requires new ways of thinking than designing in a traditional process.
The following discussion fits in that space. Page 28 3. Chapter Three: Research Method 1. The research question is analysed to find out the key elements in the question.
Analysis of the research question formulates the hypothesis. Key elements of the hypothesis are designed to satisfy the key elements of the research question. A methodological approach will be applied to research the key elements of the hypothesis.
Depending on the research findings, the hypothesis will become a valid answer to the research question or the hypothesis will formulate a partial answer with directions for future research.
An optimum time span for applying the automatic code compliance check in the design process and required skills are the secondary topic for the research. A suitable methodological approach that will integrate with the initial approach to formulate the hypothetical answer in response to the research question is investigated in the literature on research methodologies.
Presumptions of the hypothesis was investigated in the published literatures which have indicated automatic building code check utilizing BIM applications is an emerging capability of Building information modelling. Multiple theoretical code checking frameworks with intensive research prove the possibility of such operation using BIM applications. However, there remains a gap in the development and practical utilization of such BIM application. There are differences in BIM design process and traditional design process.
Synthesisation of information on stages of design process can suggest an optimum time span to draw out Page 29 maximum benefits of utilizing BIM applications in the design cycle of code compliant building construction. In construction management research studies use of liberated methodologies are observed frequently. Quantitative, Qualitative, Mixed and Review are the four broad methodological classifications in the building construction management industry research Dainty, Strategies implied in architectural qualitative researches are holistic, prolonged contact, Open-Ended, Research as Measurement Device, Analysis through words or visual material and personal or Informal Writing Stance.
This disciplinary model graphs contain Figure 3. Biglan, Page 30 parameters from applied to pure on the vertical axis and hard to soft on the horizontal axis. The proposed research topic: Automatic building code check using BIM applications relates to fields of studies of technology, management, design and law.
Les Ruddock explained an economic research method starting with a hypothesis. In that systematic approach, it included theoretical identification, data collection and pre- Page 31 Figure 3. This methodology of identifying a hypothesis and collecting, processing and selecting data to synthesize an outcome conceptually resonate with this research initiative.
Grounded theory approach suits the uncertainty of finding a suitable time span. The proposed research method was initially separated in three different stages. The intention of the separation was to help identifying particular methods to be applied in each stages and simplify the cognitive process.
First stage of the research was to collect data on building construction codes, regulatory authorities and other compliance checks bodies for building construction. Arrays of the collected data would be used to create a possible syntax which could be used in stages of the design cycle in a progressive manner. This stage of the research requires collection and processing of qualitative data.
The investigation process would include review of BIM applications, case studies of BIM applications in checking building construction code. A comparison of the BIM applications in their capabilities of automatically checking building codes would be conducted and would be presented in a formative manner. Third stage of the research would include quantitative methods. Questions would mostly be closed ended.
Data collected in this process would direct the research quantitatively. A conclusion could be drawn from this stage of the research in conjunction with the research hypothesis. Outcome of first and second stages of the research would be used in composing a guideline to utilize BIM applications code checking capabilities. Findings of first and Page 32 second stages of the research would be a complement to the third stage of the research in proving the hypothesis.
Building designers knowledge of BIM would be taken as concurrent and the hypothesis will be proven wrong. However, a reviewed research method was proposed after initial research findings in the literature which indicated auto code checking capabilities of building information modelling is at a developing stage.
Industry initiatives and academic researches exploring the possible suitable frameworks to implement auto code checking capabilities in Building information modelling applications are gradually progressing. There are examples of practical utilization of auto code checking capabilities in real projects to prove the functional capacity of proposed auto code checking framework. Available auto building code compliance check using building information modelling skills with in the building design and construction industry are expected to be significantly marginal.
A survey to collect quantitative data from users of auto building code compliance check utilizing building information modelling to determine a suitable time span of wrenching out maximum benefit has been abandoned for future exploration. The reviewed research method to derive hypothetical answer to the research question Figure 3.
Page 33 has four different stages starting with analysis, collection, synthesis and evaluation. Analysis stage comprises critical investigation of the research question with prior knowledge of the research topic. This investigation points out the key issues hidden in the research question. Key issues are then neutralizing with hypothetical answers.
The hypothetical answer is then critically analysed to find out key topics. Key topics are then separated. These separated key topics are then prepared to be investigated. Collection of data stage includes literature reviews of published articles, books, building information modelling applications.
These are more qualitative data than quantitative data. Holistic data collection approach on each separated topic is utilized. These data gets synthesized. Synthesis process is latent with in the data collection stages.
This process is more about connecting the collected data on those separated topics. Collected data logically connects or disconnects to each other which are discussed in the discussion. This process will inevitably lead to the outcome of the hypothetical answer to the research question.
Evaluation stage indicates success of the research hypothesis in relation to the research questions. This stage also discusses the failure of the hypothesis or areas of the hypothesis require improvements or corrections. Depending on the findings this stage can raise new hypothesis and create a cyclic process starting with analysis.
This mixed method has strength and limitation when applied to this research project. Firstly, the research project is limited within the time span of the course.
This time limitation attribute of the research project restricts data collection stage of this project. Collection of data on topics which have been separated in the analysis stage might not be covered with in this limited time span. Time limitation also partially blocks out the opportunity in reapplying the method to formulate different hypothetical answers to the research questions. Secondly, the research method has cyclic order imbedded within the research process.
This cyclic order of method requires intuitive initiative to terminate the research process at a certain point to verify the hypothetical answer to the research question. Otherwise, Page 34 application of this research method will continue endlessly without any fruitful research outcome which will become waste of time and effort.
Thirdly, data collection process in this research applies holistic approach. This holistic approach does not clarify funnelling or ordering system in gathering qualitative data. Qualitative data collected in this process only maintain a vogue separation in accordance with the separated topics. While researching, the above mentioned limitations will be given appropriate consideration to minimize their effectiveness on finding the suitability of the hypothesis of the research question.
The point of departure for this research project is a hypothetical research question. After analysis of the question a hypothetical answer was formulated. Further analysis was conducted on hypothetical answer to find out topics to collect data.
These collected data was synthesised to find out the suitability of the hypothetical answer to the research question. The research method also implements part of the economic research approach as explained by Les Ruddock The systematic design model has been argued as a design process to generate design ideas though good design ideas do not follow analysis and there is no solid boundary between analysis and synthesis.
The proposed research method introduces data collection stage in between analysis and synthesis stage and an evaluation stage at the end. Similar to the systematic design model approach as a design process, it can be argued that after the analysis stage of the research process the research hypothesis might not logically make sense to the research question without the collection, synthesis and evaluation stages.
Page 35 4. Chapter Four: Discussion 4. Automatic building code check is a developing technology with in building information modelling. This research project investigate an answer to the research question of finding a suitable stage to utilize the automatic code checking capabilities of building information modelling for maximum benefit. Literature review and qualitative data collected in this research study suggests building design process is individualistic.
Building design method varies from person to person. But, building design practice and building construction industries follows moderately standard design process. Research study suggested building information modelling requires different design process approach than traditional design process. This research points out structured building information modelling design process which can facilitate automatic code checking in the stages of building design process.
However, translation and interpretation of building codes remains a challenging barrier to automatic code compliance checking technology of building information modelling. Research studies and collected research data suggests only part of building codes has been interpreted in the practical example of auto code checking using building information modelling in real life construction projects.
This research project envisions the possibilities of rearranging regulatory building codes. These rearranged regulatory building codes can be applied in the stages of building information modelling in building design process. This discussion points out the possibilities of above narrated hypothetical method with limited examples form the collected data to support research findings.
Building code checking authority processes submitted building design documents applying mostly manual methods. Singapore Corenet is the automated building code checking system initiated by Singapore building construction authority in to process 2D Cad documents online.
The Corenet system was further developed to check 3d models in Eastman, In building and construction industries, building code is a vital component to get building design approved to be constructed. These rule checking systems have been arrayed in a table format which indicates the comparative overview of rule checking in accordance with the narrated rule checking process.
This comparative study recommends that building information modelling has the capability of checking building codes automatically. Focus of this research study circulates around capabilities of automatic building code checking system than any specific stages of the design process in which these rule checking systems should be applied for maximum benefits.
Review of different design processes provide enough evidences to conclude that building information modelling requires different approach to building design and construction. Preliminary design step includes checking of existing site conditions and site boundaries and regulatory site restrictions. From develop concept design step to preliminary verification step building design requires different regulatory issues to be checked and resolved such as site development restrictions, selecting building types and structures, developing building envelope design, developing and resolving environmental performances.
These suggested approximate design steps require preliminary regulatory building design codes to be consulted. Building design processes using building information modelling require intuitive restructuring of building design codes.
These intuitive restructuring of building design code varies in accordance with the experience and skills of the designer.
Current Auto code checking applications using building information modelling have limited capability and capacity to accommodate such restructuring of building design codes.
Regulatory environmental performance requirement of Australian building design code commonly named as Part J can be effectively checked by Building information modelling applications. Australian Building sustainability index Basix implies a user oriented web based input system. A basic Building information model with required environmental information is uploaded in this web based auto code checking system to measure environmental performance of building design.
An environmental performance certificate is issued after the completion of code checking. This certificate accompanied with marked plans is submitted to the regulatory authority for development or construction approval.
In this process of regulatory code checking, automatic code check of environmental performance Page 37 plays a partial and complementary role. At what stage of the building design process this environmental performance check will be conducted to satisfy Part J of Australian Building code depends on the designer. Review of BASIX compliance audit program April, informs most building designer marks plans with detailed Basix elements in their submitted plan documents at DA stage which differs very little from CC document submission, though DA documentation requires fewer details to be marked on the submitted documents.
This can cause disintegration to the overall building design outcome which might require further changes in future and might results in acquiring another environmental performance Basix Certificate at developed building design stage.
Retrospectively, design decisions made on the environmental grounds at an early stage of the building design might dominate the building design process and future changes to building design. This is required to mention that Automatic code check of environmental performance of building design stated in part J of Australian building code is a progressive process to automatic building code checking process.
But the current building regulatory check process involves two dimensional design documentation preparation and submission. The disintegration of overall design process or domination of environmental design decisions at an early stage of building design due to completed and acquired Basix Certificate is a systematic problem of checking building codes in two dimensional manual and three dimensional automatic system in which the former process maintains its systematic priority.
The Basix Certificate, a graphic or word format report generation of automatic building code check, accompanies marked plans in the two dimensional design documentation submission.
This dual systems of checking regulatory building codes involves significant time demanding preparatory efforts from building designers and architects. This time demanding preparatory efforts can be improved using solely Automatic regulatory code checks of building designs using building information modelling with higher level of efficiency in the building design process.
Automatic regulatory code checks of building designs is expected to take over two dimensional manual regulatory building code checks in future. Page 38 Figure 4. Autodesk BIM software Ecotech can perform a comprehensive sustainability analysis on building envelop. These environmental Page 39 analysis capabilities will certainly help building designers to design building with required or higher environmental performance requirements of building codes.
Figure 4. Courtesy Ecotect Figure 4. Courtesy Ecotect Page 40 Figure 4. Courtesy Ecotect. This is required to mention, Autodesk Ecotech building information modelling software does not guarantee regulatory authorities environmental performance certificate.
Page 41 Ecototech is a user oriented stand-alone Autocode checking software using building information modelling. Ecotech can help building designers and similar professional to design energy efficient building to achieve net zero energy ratings in the earlier stages of building design process.
Basix or NER certificate are regulatory requirement submitted with building plans to the regulatory authorities. Buildings designed with the aid of Autodesk Ecotech have higher chance to receive Basix certificate or NER ratings certificate with higher efficiency in the design process by saving times for modification or alteration to the virtual BIM models.
Collaboration between these Automatic code checking BIM applications from early design stages to certification can transform into a streamline design process to check regulatory building code automatically which will meet the building and construction industry demand by improving efficiency in regulatory check process and that in return will impact the entire economic development.
Further development of regulatory building code checks using building information modelling application involves Part D of Australian building code on Access and Egress.
DesignCheck has used EDM platform. Graphic evidences. These automatic rule checking systems provide sufficient evidence that Access and Egress can be checked automatically using BIM application. These BIM applications also create proven platforms to transform manual building code checking into automatic building code checking in the coming years. Specify a signing reason.
