The use of expert systems in civil engineering and especially in road construction has become a necessity due to the structure’s specificity in dimensioning, which is completely different from other structures. The parameters involved in road structure dimensioning are multidisciplinary in their values and behaviors; the road structure is complex and composed of heterogeneous materials, and its behavior is unpredictable due to the nature of the soil, the influence of climate, and different loads it supports. This expert system proposes different thickness, stress, and strain solutions by comparing them with the allowable values based on different mechanical models and formulates the methods and data sheets and then provides choices of body composition for the road based on the new version of the Algerian pavement catalog (2003). This tool is organized in the following forms: (1) rules derived from the experiences of professionals in the field. For our case, these rules are drawn from one side on the catalog of new pavements (version 2003) and another on a set of theoretical and practical method. (2) The property of GURU to call external programs of course that it is compatible. This property will help us to automate some models of flexible pavement sizing “Boussinesq Model, Westgaard Model, Odemark Model” with the Dev C++ language “which is a recent version of C”. (3) The Algerian method outlined in the catalog.

This paper investigates the bearing performance of rotary drilling screw special-shaped piles, a novel foundation solution designed to enhance load-bearing capacity in geotechnical engineering. Combining engineering-scale tests with numerical simulations, the study evaluates the interaction between piles and surrounding soil, with particular focus on the effect of thread geometry. The proposed orthogonal simulation model assesses the influence of key design parameters such as thread height, pitch, and pile length on compressive bearing capacity and end resistance. The results demonstrate that the thread structure increases the interaction area between the pile and soil, improving side friction resistance and overall bearing capacity. A method for calculating the bearing capacity of screw special-shaped piles is proposed, based on Meyerhof’s theory for deep foundations, which is validated through experimental data. This research provides valuable insights for optimizing pile foundation design and offers a reliable approach for calculating bearing capacity. The findings highlight the potential of screw special-shaped piles to enhance structural stability and material efficiency in challenging geotechnical conditions, offering a solid foundation for future studies on advanced pile systems in civil engineering.

Digital twins (DTs) have witnessed a paramount increase in applications in multidisciplinary engineering systems. With advancements in structural health monitoring (SHM) methods and implementations, DT-based maintenance and operation stages have been implemented significantly during the life cycle of civil infrastructure. Recent literature has started laying the building blocks for incorporating the concept of DTs with SHM of large-scale civil infrastructure. This paper undertakes a systematic literature review of studies on DT-related applications for SHM of civil structures. It classifies the articles based on thematic case studies: transportation infrastructure (i.e. bridges, tunnels, roads, and pavements), buildings, off-shore marine infrastructure and wind turbines, and other civil engineering systems. The proposed review is further uniquely sub-classified using diverse modeling approaches such as building information modeling, finite element modeling, 3D representation, and surrogate and hybrid modeling used in DT implementations. This paper is solely focused on applications relating DTs to SHM practices for various civil engineering infrastructures, hence highlighting its novelty over previous reviews. Gaps and limitations emerging from the systematic review are presented, followed by articulating future research directions and key conclusions.

Nowadays, the usages of Terrestrial Laser Scanner (TLS) have been practise widely use in the mapping and modelling of varies field. This is because of the advantages that TLS provided; such as speed in data collecting, high accuracy as well as saving time. One of the main technologies of TLS is by producing a 3 Dimension (3D) that can be analysed from a surface of an object and form of the real world. TLS is practically use in Civil Engineering or Geographic Information System (GIS) for objects modelling and reviewing tunnels volume whereas for Archaeology it be used by maintaining the details of cultural heritage. However, TLS has not been analysed in 3D for the parking area. The main purpose of this study took place is to prove the ability of TLS in producing and analysing into 3D modelling for this particular area. The study has been done at the parking lot of the Department of Survey and Mapping (JUPEM), Kuala Lumpur. The methods that been used for this study are by using a 3D Terrestrial Laser scanner (TLS), Leica Scan Station C10, image point cloud registration, 3D modelling, Cyclone software, parametric modelling 3D and Autodesk Revit. From this study, it helps the JUPEM department in producing 3D detailing plan as well as speed up the outcome of retrieving details for an object and can be presented in tangible form without physically going to the particular area or a site. Therefore, with this introduction of 3D modelling technology towards the relevant fields, it can help others in solving problems for internal infrastructure for buildings and structures.

A new engineering activity, Urban Systems Engineering, is emerging in response to the increasing demands of urbanization. Contributing to this activity are mathematics, economics, and the social, behavioral and institutional sciences (law, government, etc.), all of which pyramid upon an engineering base. Analytic methodology, theories and descriptions of the behavior of urban systems and institutions, and the use of inductive and deductive quantitative methods are particularly important. The civil engineering profession has a major opportunity in Urban Systems Engineering. Areas of responsibility and leadership should be identified and accepted enthusiastically, for if the civil engineering profession fails to meet this challenge effectively, the job will be done by others.

Two types of software that make the handling of huge quantities of data easier are described and compared. The first is an expert system which processes extensive and complicated knowledge. It works interactively with the user when it acquires information which is being compared with the facts and relations contained in the knowledge base. The second type of software is a database system which is a record-keeping system that organizes and maintains information and makes it available on demand. Examples of expert systems and database systems in civil and structural engineering are given.
