Introduction

I. INTRODUCTION

Systematic procedures are urgently needed to ensure responsible and sustainable operations in light of the complexities and difficulties involved in sand extraction. This entails creating all-encompassing plans that incorporate geological evaluations, cutting-edge technology, and environmental regulations. Striking a balance between the needs of the building sector and protecting the environment requires a comprehensive approach.

Essentially, the background underlines the importance of sand in building, the difficulties involved in extracting it, and the need for methodical and sustainable solutions to the problems this essential business faces. Deeper exploration of these complications is the goal of the next dissertation, which will provide answers and ideas for efficient planning and administration of sand mining in quarries.

A. Sand Excavation in India: A Scenario of Contrasts

When it comes to sand excavation, India—a country with enormous landscapes and a wide variety of resources—faces a challenging situation. Sand, on the one hand, is an essential resource that drives the nation's rapidly expanding infrastructure and building sectors. However, the careless extraction of it presents significant environmental and societal issues.

The Demand Boom: India's ambitious infrastructure projects and quick urbanization are fueling the country's building boom. Sand demand has skyrocketed as a result; it is projected to be approximately 5.5 billion tons per year. Sand excavation is the main method used to meet this demand from:

1. Riverbeds: Historically, India's main supply of sand has come from its rivers. However, over-exploitation has damaged ecosystems, eroded riverbeds, and put the livelihoods of communities that depend on the rivers in jeopardy.
2. Quarries: Sand is additionally taken out of quarries that are situated on land. Although this may not have as much of an impact on river ecosystems, it still poses issues with dust pollution, damage to the environment, and groundwater depletion.
3. Illegal Mining: Sand extraction in India is regrettably carried out in large part illegally, frequently by sand mafias operating outside of laws governing the environment or obtaining permits. More environmental harm and societal unrest result from this.

II. LITERATURE REVIEW

By connecting the network activities of a project schedule with the three-dimensional (3D) components of a building information model (BIM), numerous researchers and construction practitioners have created four-dimensional (4D) models. With the exception of the 3D components, the BIM offers little information in such a 4D model. This study suggests an interface system that uses the BIM's capacity for quantity takeoffs of necessary materials (such as steel, forms, and concrete) to support site-level operations simulation, ultimately leading to the generation of a project schedule (Wei-Chih Wang et al 2014) [1].

Large-scale biogas plant construction projects require a complex web of interdependent tasks that must be coordinated over a wide range of timeframes. As a result, the critical path method (CPM) is used in this study to analyze the application of planning and scheduling for the construction of biogas plants. The findings showed that, if there are no delays, building a 50 m3 biogas plant with a fixed dome in Iran could be finished in a minimum of 38 weeks. Additionally, a project network is suggested to illustrate the connections between the tasks and track the project's advancement (Samira Zareei 2018) [2].

According to the study, AR works well for worker training, progress tracking, scheduling construction projects, safety management, time and cost management, and quality and defect management. Virtual reality (VR) is a useful tool for quality and defect management, worker training, safety, and visualization. Furthermore, a network that enables the option of holding conferences with people who are physically separated from one another or the building site is developed using AR and VR. This study could aid in investigating the possible applications of AR and VR technologies as profitable, time- and money-saving aids in the construction sector (Shakil Ahmed, et al 2018) [3].

In this article, "structurally stable sequencing" refers to the erection sequencing order in which the structure maintains statically stable conditions both locally and globally throughout the installation process. The authors created 21 distinct experiments and applied the suggested technique to create stable construction schedules in order to validate the methodology. Each experiment was completed satisfactorily. As a result, this methodology suggests a novel way to use the GA as an Expert System tool in building projects (Vahid Faghihi et al 2014) [4].

The simulation-based auction protocol (SBAP), a hybrid framework developed by the authors, enables efficient resource allocation in large-scale projects. The SBAP framework is used in this study to satisfy a number of constraints and allocate resources (such as space and a skilled crew) in an efficient manner. This system gathers information from an extensive database, executes the simulation model in the background, and provides a range of graphical outputs to help project managers and superintendents make important project choices. The created system may also efficiently level resources, schedule fast-track modular construction projects with minimum data, and schedule resources (e.g., space, staff) depending on different shifts and calendars. This paper's case study illustrates the possibilities of the system that was built for organizing module assembly yards (Hosein Taghaddos et al 2012) [5].

The construction and site management, cost and schedule management, risk analysis and management, innovation and information technology use, and leadership and professional development subareas were found to have a large number of theory-based findings published in them. Particularly in developing nations without a research culture, the subfields of organization and stakeholder management, project planning and procurement, and project monitoring and control continue to be potential areas for future study. Future global collaboration can further advance megaproject research by using institutional theory and complexity theory as the theoretical underpinning in these subareas (Kim, S., et al 2020) [6].

A genetic algorithm has been utilized for the optimization process because of the multitude of options available for the execution of the activity. Multiple test scenarios were used to test the algorithm, and the outcomes were compared to those produced by Microsoft Project. The assessment reveals that the suggested algorithm is capable of producing sufficient and well-rounded answers about the three goals, and that these answers surpass those offered by for-profit project scheduling software (Sofia Kaiafa, et al 2015) [7].

III. METHODOLOGY

PRIMAVERA's critical path analysis is used to determine the order of tasks that establishes the project's overall schedule. Project managers may make sure that the project moves forward smoothly and meets production goals within predetermined timeframes by optimizing resource allocation and streamlining work sequences. This is achieved through a thorough grasp of the critical path.

A. Allocating and Optimizing Resources

PRIMAVERA resource allocation and optimization methodologies are integrated by the methodology. This involves allocating workers, equipment, and supplies to various activities effectively in accordance with their dependencies and availability. Resource optimization makes ensuring the quarry runs as efficiently as possible, cutting down on downtime and increasing output.
