I. OBJECTIVES TO STUDY
A. Factors Affecting On Time
Inadequate construction planning can result in delays, disruptions, and even the cessation of construction activities. When construction plans lack thorough consideration, unforeseen challenges may emerge during execution, leading to setbacks, interruptions, and potential project standstills. Poor communication exacerbates these issues, fostering project failures due to breakdowns between project owners, teams, and stakeholders.
Equipment breakdowns further compound delays, directly impacting project completion timelines. Persistent labor shortages have plagued the construction industry in recent years, impeding companies from filling essential positions and jeopardizing project schedules.
Effective communication during construction projects significantly influences retention rates and project performance, as evidenced by scenarios depicted by construction workers at industry forums. Design changes, while sometimes necessary for improving project quality, functionality, or aesthetics, also pose risks of indirect costs, claims, and disputes. Critical design alterations may trigger successive delays, necessitating revised drawings to inform on-site personnel promptly.
While design changes during construction are often unavoidable, they must be managed carefully to mitigate associated risks. Despite their potential benefits, these modifications can escalate project timelines, expenses, and team conflicts.
Slow decision-making processes in construction have detrimental effects on project performance, particularly when clients' decisions are delayed, impeding contractors' progress and potentially leading to increased claims for additional time and costs. Inadequate coordination and management at project sites exacerbate decision-making delays. Furthermore, poor communication among project participants poses significant risks to large-scale infrastructure projects, emphasizing the necessity for efficient coordination efforts among stakeholders.
A pressing issue in the construction industry is the dearth of capable leadership capable of making prompt decisions during large-scale infrastructure projects. Delays in work approval, particularly in submittal approval, can prolong project completion dates, incurring additional costs and causing frustration among stakeholders. Poor communication practices within the industry exacerbate project delays, manifesting as delays in information flow, misdirected communication, and unclear communication leading to confusion.
Design changes are another significant contributor to construction project delays, necessitating careful assessment of their impact and effective communication with stakeholders to ensure project continuity. Regular construction site inspections are crucial for ensuring compliance with project plans, specifications, client requirements, and code regulations. These inspections, facilitated by construction management software, are vital for quality control, worker safety, and productivity. Delays in inspection processes can result in cost overruns, legal disputes, financial losses, contract failures, disputes, arbitration, litigation, project abandonment, and impossibility.
The complexity of projects is also a major contributing factor to delays and cost overruns in the construction industry.
Complexity in construction projects can be delineated by their scale, with mega projects like dams, motorways, skyscrapers, and nuclear power stations often requiring extended implementation durations compared to smaller endeavors such as residential houses or non-commercial buildings. This discrepancy in duration can trigger fluctuations in material prices, exchange rates, and inflation rates, necessitating supplementary budgets to ensure project completion. Consequently, increased costs and prolonged negotiations ensue, leading to overall project delays.
Moreover, projects characterized by high complexity typically entail intricate plans, schedules, and estimations. Failure to adequately address these complexities may result in variation orders, further exacerbating time delays and cost overruns. Additionally, managing project quality becomes challenging due to the involvement of diverse stakeholders with varying interests and protracted communication chains, leading to sluggish feedback loops.
In summary, the scale and complexity of construction projects, along with the associated fluctuations in material prices and exchange rates, can precipitate budgetary supplements and prolonged negotiation processes, ultimately leading to delays and increased costs. Furthermore, intricate project plans and diverse stakeholder interests exacerbate these challenges, underscoring the importance of proactive management strategies to mitigate potential disruptions.
Before commencing any project, the Employer typically conducts a thorough assessment to determine the initial investment required, relying heavily on an Engineer's estimate. This estimate serves as the foundation for all subsequent economic calculations and benefits analysis, underscoring the need for realistic cost figures. To generate an accurate Engineer estimate, a comprehensive approach is essential, involving detailed investigative studies, extensive design expertise, clear scope delineation, precise quantity calculations, and meticulous planning.
Inaccuracies or errors in estimation can lead to cost overruns, subsequently causing delays in project timelines. Achieving accuracy in engineering estimation necessitates proactive engagement with all project stakeholders to gather pertinent information. Effective communication with design teams and clients further enhances the accuracy of engineering estimates.
Material and equipment management play pivotal roles during project execution, representing significant cost outlays. Materials alone typically account for 60% to 70% of the direct costs in construction projects. Therefore, minimizing procurement or rental costs can significantly impact overall project costs. A robust materials and equipment management system ensures the selection, procurement, transportation, delivery, and handling of materials and equipment on-site are conducted efficiently, timely, and at reasonable costs.
Poor management practices can result in substantial and avoidable costs, as well as delays in critical work completion due to material and equipment unavailability. Effective construction management prioritizes the efficient utilization of materials and equipment.

B. Factors Affecting On Cost
Corrupt practices and kickbacks pose significant threats to the integrity of construction projects. The total construction cost encompasses all expenses related to building the structure, including material costs, labor expenses, and overhead. Similarly, the total square footage represents the overall area of the structure, covering both interior and exterior dimensions. Often, many contracts are overlooked until their renewal, which can result in substantial financial losses for businesses, estimated at around 9% of total income, according to research conducted by the International Association for Contract and Commercial Management.
Research indicates that between 10% and 25% of project costs are lost due to errors, including both direct and indirect costs. The impact of forecast errors on a company's finances can be significant, but minimizing errors can lead to substantial savings, such as reduced inventory, production costs, and avoidance of stock-outs.
There are five primary types of construction cost estimates: preliminary, detailed, quantity, bid, and control, each serving distinct purposes at different project lifecycle stages. These estimates involve analyzing tasks, duration, and required resources, along with anticipating associated costs.
The choice of procurement method significantly influences construction project costs. Various procurement methods exist, including the Traditional Method, Management Contracting, Design and Build, and Joint Partnership or Venture. Each method carries its own set of risks and benefits, and selecting the appropriate method can be a challenging decision, even for seasoned industry professionals.
When material prices experience a significant increase, such as a 15-fold rise, it profoundly impacts construction project costs. This surge in material costs, whether it's steel, concrete, lumber, or others, directly inflates overall project expenses. The escalation doesn't just affect material procurement; it also drives up labor costs due to the need for specialized handling or construction techniques with pricier materials. Furthermore, subcontractor pricing may also be influenced, exacerbating the cost escalation. To counteract these impacts, construction projects may need to reassess budgets, explore alternative materials, negotiate pricing with suppliers, or seek cost-sharing arrangements with clients.
Efficient project management in construction entails optimizing the use of labor, materials, and equipment. Continuous improvement in labor productivity is essential for effective cost control in construction projects. Material handling, including procurement, inventory management, fabrication, and field servicing, requires focused attention to reduce costs.

II. LITERATURE REVIEW
A.. International Journal of Creative Research by Henry, Jackson and Bengt-
Various researchers have identified a plethora of factors influencing project duration (time) across different construction industries. Among the most significant challenges are material shortages, incomplete drawings, inadequate supervision, lack of tools and equipment, absenteeism, communication gaps, subpar site layout, inspection delays, and rework. Cost and time control, the process of managing a construction project's expenses and schedule, is paramount for ensuring project completion within budget and schedule constraints, without disrupting stakeholders. This control mechanism involves continuously monitoring actual costs and time performance against initial estimates, identifying any deviations, and implementing corrective measures to address issues and optimize performance.
Construction cost and time control significantly impact project cost and quality. Project managers encounter numerous challenges in executing this process, notably managing project schedules and ensuring adherence to budgetary constraints. Cost overruns, a prevalent issue in construction projects, occur when actual project costs surpass initial estimates, putting pressure on investments and project completion. The cost limit represents the maximum expenditure the client is willing to allocate to the project, while the target cost denotes the recommended expenditures for specific project aspects.
Construction projects frequently exceed estimated costs due to suboptimal cost and time management practices, a problem observed globally across developed and developing countries. Enhancing the cost and time control process is imperative to ensure projects are completed within budgetary and scheduling constraints. By addressing these challenges and optimizing cost and time management practices, construction projects can achieve greater efficiency and success.
B. Evaluation of Factors Affecting the Quality of Construction Project by Olomolaiye, Jayawardane and Harns-
In the Nigerian construction industry, several significant factors influence time management. These include material shortages, rework, equipment availability, delays in supervision, absenteeism, and interface issues. Time overrun, a common occurrence in construction projects, occurs when a portion of the project is completed later than the initially agreed-upon completion date or not as planned due to unforeseen circumstances. These delays, often referred to simply as delays, are events that extend the time required to finish all or part of a project.
Cost overrun, on the other hand, signifies the actual cost exceeding the budgeted amount. Terms such as "cost increase" or "budget overrun" are used interchangeably to denote cost overruns. The calculation of cost overrun involves determining the disparity between the original cost estimate and the actual construction cost upon project completion. These phenomena are ubiquitous in construction projects and can significantly impact project outcomes if not managed effectively.
C. Factors Affecting Overruns Construction Time and Cost by Henry, M. A., Jackson, A.M. and Bengt, H.-

E. Factors Affecting Time, Cost and Quality Management in Building Construction Project by M. Doddurani-
Various researchers have delineated an array of factors influencing project timelines across diverse construction sectors. Predominant challenges impacting project duration encompass shortages of materials, incomplete drawings, substandard supervision, inadequate tools and equipment, absenteeism, communication lapses, deficient site layouts, inspection delays, and rework occurrences. Additionally, an examination of cost and schedule vulnerabilities associated with the establishment of 20 low-income housing units in Tripoli, Libya, is expounded upon in the text. This analysis entails Monte Carlo simulations to assess pre- and post-mitigation scenarios in comparison to the original plan, revealing a distribution of risks comprising 55% low risk, 25% moderate risk, and 20% high risk. Furthermore, a Failure Mode and Impact Analysis conducted within a case study in China identifies five unacceptable hazards, including incidents such as "hole in the ground at construction site," "collision with falling objects," "running through operating equipment," "elevator shaft falls," and "scaffolding falls." Recommendations are proffered to enhance Occupational Health and Safety (OHS), environmental, and quality measures to instigate comprehensive risk management practices. It is emphasized that risks do not manifest linearly, necessitating alternative tools to comprehend their interconnections. To map the risk landscape effectively, organizations are encouraged to simulate diverse accident scenarios and employ tools addressing risk interdependencies. The study aims to ascertain the cumulative impact of risks on project performance and value, facilitating the selection of an optimal blend between risk retention and treatment strategies. Proposing an agent-based model termed SMACC, the paper endeavors to evaluate loss repercussions on a project and evaluate various risk mitigation approaches to gauge their efficacy. The text underscores the indispensability of effective risk management for project prosperity, albeit acknowledging the complexity engendered by the multifaceted and dynamic nature of risks. Each project is posited to harbor its unique set of risks, necessitating tailored focus and actions. Additionally, the study canvasses an extensive spectrum of domains encompassing external risk management, finance, politics, and national cultures, with an abundance of literature in each sphere accentuating the significance of risk management. Although external risk management stands as a pivotal success determinant for construction entities venturing beyond their domestic realms, it is often disregarded by firms lacking adequate acumen in external risk management or failing to recognize its ramifications on their operations.
