Abstract There are three major constraints of Project Management: the Time constraint, the Cost constraint and the Scope/Quality constraint. As the name suggests, the Time constraint refers to the time available for the completion of the project, Cost constraint refers to the allocated budget and the Scope constraint refers to the final expected outcome. For a construction project, it is virtually impossible to achieve the best of all worlds, i.e., cheapest, fastest and of the desired quality. Due to the dynamic nature of a construction project, a construction engineer faces a large number of complex problems. As a result of which, the cheapest method may yield a product which falls short in quality or the fastest means to achieve the …show more content…
Trade-offs between the total cost, duration and overall quality is an issue that is commonly discussed by all project managers. The goal of this trade-off analysis is to come up with a plan that minimizes the cost and duration while meeting the quality as demanded by the owner. Understanding the dynamic inter-relationship between these parameters is essential for planning a successful project that satisfies all parties (Owner, Construction Manager, Contractor, and Consultant).  During 1970 to 1990, a one-dimensional approach was followed. The primary aim of project managers was to reduce the total cost of the construction project. Gradually, ‘Time’ was considered as the second factor in addition to the cost of the project. This was a two-dimensional approach. Quality was introduced as the third dimension by the end of 20th century. More recently, another dimension, scope, has been realized as an equally important factor while carrying out a trade-off analysis to optimize the overall output of the project. See the figure below which graphically shows this evolution of contracting methods. Figure 1: Evolution of Contracting Methods Construction industry is very volatile and involves huge amount of uncertainty due to numerous stages involved in any construction project. The construction industry in the US contributes about $600 billion, which is approximately 5% of the total GDP of the country. So

Choosing the most suitable procurement method for the specified construction project is a long term hard decision; it is a
This document serves the purpose of critically analysing the differences that exist between managing construction projects and I.T Projects
Over the past few years, the construction industry has been changing dramatically. One of the most important stages in the construction management and business management is the planning phase. They share similar two main levels of planning which are the strategic and operational planning. However, business management planning to decide in advance what should be done, and how to do it, when you do and you are done. On the other hand, Construction management strategic planning is to deal with selection on a high level of overall objective of the project, including the scope, procurement methods, schedules and financing options but the planning of operations, including the
A project has many factors which determine its level of manageability and success. These factors can be considered constraints which may cause delays or difficulties. The most important criteria for a balanced project is often quoted as the careful organisation of these constraints. Constraint reducing techniques are used to better equip a Project Manager for success. These techniques are accomplished through the use of practical guides or methods, improving communication and personal skill of the Manager.
The design and construction of buildings can be a complicated business involving different professions, contractors, sub-contractors and operatives. This type of work is varied and employs many construction personnel with different roles and responsibilities, working together to complete a project in as successful way- on time, on budget and to the right specification. A large project would involve a great number of different activities:
According to the Associated General Contractors of New York State, “The construction industry is the second largest employer in the US, second only to all government employees including the armed forces.” (Associated General Contractors of New York State, 2014). This is a staggering number. However, in spite of this, the industry has suffered a decline in labor productivity beginning in the 1960’s that has continued its trend since that time and seems to be in no hurry to reverse its course (Teicholz, 2013). This paper will explore how Integrated Project Delivery (IPD) can be implemented by the construction industry to solve this issue by greatly decreasing (or even in some cases, eliminating) low productivity and waste, time/cost
Most scholars have accepted generally the triple constraints as key elements of project success. If one of these three constraints get reduces it will have an impact on the other one, balancing between them is crucial for project managers. It is said that “To create a successful project, a project manager must consider scope time and cost and balance these three often-competing goals”.
Construction projects are always unique and risks raise from a number of the different sources. Construction projects are inherently complex and dynamic, and involving multiple feedback processes. A lot of participants – individuals and organizations are actively involved in the construction project, and they interests may be positively or negatively affected as a result of the project execution or project completion. Different participants with different experience and skills usually have different expectations and interests. This naturally creates problems and confusion for even the most experienced project managers and contractors.
It is clear to see that throughout the project the tasks and progress were monitored very closely. The project is heavily dependent on the resources provided by its shareholders and in turn they rely on regular updates to reassure them on their investment. In the construction and building industry the methods and application of project management tools are very reliable and well tested. Therefore, it could benefit the project if the it was managed with detailed and defined practises and also follow standards set and agreed upon on a international level.
The design and construction contract offers the following advantages: shorten design time Simplify construction plans, alternatives to value engineering are always available for discussion and analysis, reduce construction schedule, minimize communication channels with a single point of contact, minimum change orders, quick calendar, adapted to the actual conditions of the site easily, identify the elements with a long previous term, allowing to repeat the project.
The completion of any project depends on the execution of various parameters mostly set at the beginning of the project. In order to complete the project to satisfactory levels, the project must be completed within the stipulated timelines, fall within the approximate budget and be of the required quality standards. However, most of the projects are affected by adverse changes and unforeseen events that occur during the execution period. Research shows that the magnitude of change is dependent on the size of the project, with large projects experiencing more uncertainties due to several factors including; planning and design complexity, interest groups having deferring opinions, resource availability, Economic and political climate and statutory regulations, which may necessitate change of plan. Most of the uncertainties are known to occur in the concept phase and if not intervened, they may affect the entire project. The burden falls on the management of such risk as some managers choose to ignore the uncertainties since they call for additional costs. Other inherent risks may go unnoticed and therefore remain unsolved,
To select a suitable procurement strategy for a construction project, there are some issues which need to consider. From all of those issues, there are 3 big issues that mainly affect the selection decision which are time, cost and quality. There is several type of procurement strategy available in market that commonly used for construction project and each of the common method will be analyze and compare to find the most appropriate method for this project. The choice of procurement strategy is very important to the success of a construction project. Therefore, the characteristic of each strategy have to analyze and also its relative advantages and disadvantages. A recommendation of most appropriate procurement
A key activity in project management is assessing project constraints. A project has three limitations: scope, budget and schedule. These limitations are project constraints because they are sensitive to change and have an impact on project risk. Risk is exposure to uncertain outcomes. Project constraints are mutually exclusive. If one constraint changes it affects the others and adjustments may be required to compensate and manage risks. For example, a delay in the schedule can increase the risk that the project will not finish on time. Time is money and delays have a negative impact on the budget. To
I am an elder son of a real estate banker; my father is always busy with the analysis of construction project budgets. He had his own library, with books ranging from construction estimation to procurement systems. These books are the seeds of curiousness inside me about the buildings and the science behind them. My mother being a mathematics teacher, made sure I had a strong grip over that subject all through my schooling. By the time I had to select my path into graduation, I was already inclined towards construction industry and opted for Architecture. It was a challenge to get selected among one million applicants. I graduated from “School of Planning and Architecture, India”, An Institute of National Importance, among the top three architecture schools in India. It was my mother’s mathematical nourishment which appreciated my chances of standing in top 0.001% (All India Rank – 870) in All India Engineering Entrance Exam. I was eager to contribute to the body of knowledge in construction industry and searched for the direction which can add value to the system. India being a developing country with world’s second largest population, construction resources are very important. I have observed a lot of scope for growth in the commercial sector and felt that thrifty approaches towards generic construction problems in commercial sector are to be modulated.
