Extant literature indicates that poor design documentation quality often results in construction project inefficiency. However, there is less effort by researchers to identify and empirically assess ...the significant impacts of design documentation quality on project delivery. Therefore, this study seeks to empirically assess how poor design documentation quality impacts construction project delivery. This study is a sequel to a study by the same authors that reviewed literature on the impacts of design documentation quality on project delivery based on a meta-synthesis approach. Therefore, the outcome of the meta-synthesis was developed into a questionnaire and distributed to project managers, architects, engineers, quantity surveyors, and site supervisors based on purposive sampling which obtained 127 responses. Data were analyzed statistically by determining the Relative Importance Index (RII) of each factor. The findings indicate project delays, project abandonment and cost overrun as significant impacts on project delivery. Also, improving collaboration between design disciplines and specialists' involvement during design are significant strategies to improve quality. The results provide pragmatic data to help enhance initiatives toward quality improvement. However, future studies should aim at developing a framework to improve design documentation quality.
The article is devoted to the process of digitizing paper archives at the machine-building enterprise. The manual method is used for post processing of images by means of graph editors. The other ...method is based on the use of the open source library OpenCV; it allows employees to correct positioning errors of scan images of engineering drawings automatically at the stage of scanning.
There are numerous studies on design documentation variables without efforts to evaluate their level of importance. Therefore, the aim of this study is to evaluate the significance of these variables ...towards improving design documentation quality. A questionnaire survey to identify the significance of key quality variables was carried out. A total of 139 variables on design documentation quality were used. The mean score and Standard deviation of each factor were used to determine the level of significance. Based on responses from 112 construction industry players, the significance of each variable is determined. Design documentation is fit for purpose was considered highly important as an attribute while Inadequate and Insufficient documentation was ranked highest for quality influential factors. The findings will provide valuable data to stakeholders, researchers, and academics and will help enhance project performance because professionals will be aware of key factors that can influence design documentation quality. It will also aid in providing solution to sustainable infrastructure design and delivery challenges in the industry. The study offers a pragmatic data and empirical evidence to expand knowledge on design documentation quality. It is the first of its kind that explored the significance of design documentation quality variables based on the outcome of a meta-synthesis.
The process of designing a building involves producing design concepts while fulfilling various requirements and regulations. Furthermore, during the project's life-cycle, multiple experts from ...multiple domains collaborate in developing the different partial models, including architectural, structural, and HVAC among others. Accordingly, clearly communicating the rationale behind design decisions is crucial for developing regulatory compliant designs that also fit the owner’s needs. The developed designs are the main deliverables exchanged and handed over. However, these deliverables do not include any explanation of design intentions or documentation of design decisions. Communication among parties and reuse of knowledge are hindered by the absent explanation of existing design. To overcome this deficiency, this paper proposes a methodology for digitally documenting design decisions, incorporating their intention and rationale. Architectural concepts and evaluation criteria are represented in the form of explanation tags as well as spatial and semantic constraints, which are assigned to the individual model elements and properties. Additionally, to document how design decisions fulfill owner requirements and regulatory documents, natural language processing (NLP) is employed to facilitate querying those documents and then the individual requirements are linked to specific elements, properties, and constraints. To evaluate the proposed methodology, a prototype was implemented as a plugin inside a BIM- Authoring tool and multiple real-world use cases are discussed.
We have developed and realized instrumental means for automated support of end-to-end design process for design documentation on a product at the programming level. The proposed decision is based on ...processing of the engineering project data that are contained in interdependent design documents: tactical technical characteristics of products, data on the valuable metals contained in them, the list of components applied in a product and others. Processing of engineering data is based on their conversion to the form provided by requirements of industry standards for design documentation preparation. The general graph of the design documentation developed on a product is provided. The description of the developed software product is given. Automated preparation process of interdependent design documents is shown on the example of preparation of purchased products list. Results of work can be used in case of research and development activities on creation of perspective samples of ADP equipment.
Making a hardware open-source consists of making accessible the documentation of the system so that everyone can use this design for its own purpose. It is an increasing phenomenon that goes hand in ...hand with the developments of the makers movements and the underpinning societal changes that are at stake today. However, poorly structured communities are sometimes struggling with problems inherent to the reuse of exiting designs. Besides, the exponential number of web-sites and platforms hosting open-source projects makes it almost impossible to properly find similar products or designs to get inspiration from. Design reuse has been an important practice in industry since decades. This paper looks for exiting design reuse research work and makes an attempt to elicit the main characteristics of design reuse identified in the literature. From this, we discuss the conditions of the application of design reuse for open-source hardware products. We conclude that a goal-oriented approach based on the basic principles of open-source hardware (right to study, modify, make, distribute) can be used to structure the approach towards a documentation that allows capture of design rational, documented product models and guidelines for documentation practices.
The present study described a group of factors that may influence the decision to participate in a tender, when the subject of the order is the preparation of design documentation. The importance of ...the proposed factors was based on the opinions of designers who perform such services at the construction market. This analysis is followed by an assessment of the conformity of the opinions by means of the dispersion coefficient of relative ranking. The values of the dispersion coefficient of a relative classification differ considerably, from one another depending on the value under assessment. Yet, it is worth noticing that in the assessment of the factors influencing a bid/no bid decision, experts’ subjectivism cannot be avoided.
PurposeDesign rationale is design information that explains why an entity is designed as it is. This paper investigates how the documentation process and the use of documents in service design ...projects influence the reuse of design information across projects.Design/methodology/approachThis study analyzes two sets of data collected through interviews and field observation. It first applied Lund's (2004) four elements of documentation process to categorize the collected data. Then it used bottom-up data analysis approach to identify patterns of the documentation process.FindingsThe author speculates designers' focus on certain documents' social aspect instead of material aspect influences how they reuse design information across projects. Some documents are important because they represent a consensus, and some are important because of the document producers rather than its content. The author also found a similarity between economists and service designers by comparing the study results with Harper and Sellen's (1995) findings. Based on the comparison, the author concludes that detailed research reports are easily reusable across design projects. Finally, although the author observed that designers are using templates to explicate design rationale, the created content is not used across projects.Originality/valueThis study identifies six types of documents that are commonly created in service design projects, three types of producer involvement and three types of provisional design outcomes. It also provides two suggestions for designers to reuse design information across service design projects better and two implications for future study.
