Comparative Study of Construction Information Classification Systems: CCI versus Uniclass 2015

Abstract

By classifying BIM data, the intention is to enable different construction actors to find the data they need using software and machines. The importance of classification is growing as building projects become more international, generating more data that rely on automated processes, which help in making better decisions and operating devices. Different classification systems have been developed around the world. Each national construction information classification system (NCICS) aims to classify information on the built environment and thus meet national needs and ensure compliance with the principles of regional and international building information systems. The research purpose of this paper is to present a comparative assessment of two construction information classification systems, CCI and Uniclass 2015. The following methods were used: the expert assessment of NCICS alternatives; the assessment of NCICS alternatives; and a strengths, weaknesses, opportunities, and threats (SWOT) analysis of NCICS alternatives. We concluded that in the initial phase of NCICS development, CCI ontologies should be adopted as a base consisting of construction entities, spaces, and elements, with the gradual addition of complexes of buildings and infrastructure, along with roles and phases of the building life cycle (BLC). An explanatory NCICS development note should be drawn outlining the principles of classification and identification; the ontological structure; development and updating possibilities; methods of integrating existing national and international classification systems; and methods of integrating data of construction products, time, cost, or other individual characteristics.

Civil Engineering Standard Measurement Method Adoption Using a Structural Equation Modelling Approach

“…There will be less room for error in estimates, valuations, and cost-control formulations, according to previous research, because of the standard of measurement's consistency, precision, and uniformity. The reference provided by the standard will be consistent and straightforward [17]. The standard will be more transparent and unambiguous with the use of technology, as [9] said.…”

“…Better enforcement of the standard technique of measuring implementation has been cited as the most effective way for promoting its use in civil engineering. Given the wide range of building codes, it is prudent to strictly adhere to the measuring standard as described in [17]. Moreover, ref.…”

“…Standardizing measurement procedures reduces disagreements, the third literature-identified motivation. Singapore's standard would reduce legal disputes [17]. According to [24], the norm will reduce vague-wording claims and conflicts.…”

“…Ref. [17] suggests financial and other market-based incentives, low-interest loans, and government subsidies to promote the adoption of a consistent evaluation method. Government-led initiatives are needed to reform and standardize industry.…”

A Multi-Story Expandable Systematic Hierarchical Construction Information Classification System for Implementing Information Processing in Highway Construction

“…Uniclass also considers the infrastructure sector [21]. However, its utilization in infrastructure is low because it primarily focuses on buildings [22]. Omniclass makes similar assessments [23][24][25].…”
