Abstract- The construction of tunnel is important for different purposes. They can be constructed for railways, roadways, pedestrian footways and can be built in hard rock, soft ground, river bed and are also used to convey Hydroelectric power, water stream, or as a sewer. The construction of Diversion Tunnel, Pressure Shaft, and Tailrace Tunnel to convey water is considered in this project. To identify Scheduling of different activities by various methods Network Diagram, C.P.M., P.E.R.T. and their cycle time is calculated. Scheduling for different activity is carried out with the help of Network Diagram & Primavera Software will be carried out in a project stage II. Study of Estimation for a Diversion Tunnel, Pressure Shaft, and Tailrace Tunnel by both methods. Excavation in heading and benching, Rock bolt support work, lining work is considered for cycle time and cost estimation calculation in Diversion Tunnel, Pressure Shaft, and Tailrace Tunnel. Estimation is also carried out by two methods. The comparison of two methods adopted for excavation work and estimation will be carried out in a project stage II.

Keywords- Scheduling, C.P.M., P.E.R.T., Gantt chart, Network Diagram, Estimation, Heading, Benching, Cycle time, Lining, Rock Bolts, Diversion Tunnel, Pressure Shaft, Tailrace Tunnel.

Introduction:
Tendering is getting bids for big projects, which a government agency usually does. The most important parts of the building tendering process are favoritism and crime when giving projects to architecture firms. A tender is an economic incentive to do work. During the early stage of this tender resolution, framers will be asked to submit waterproof tenders for construction at a certain time. In this article, we will learn about tendering process in construction.

What is Site Preparation?
The term “site preparation” describes the actions taken before an engineer begins their work. The site cleared in preparation for the new building is called the old or unfriendly site. Since the land and structures already there are suitable for the construction work that will soon begin there, site preparation is not required.

Before construction, the site must be prepared by demolishing old buildings, clearing building sites, mapping underground services and wires, doing a site survey and layout, and treating termites. To get a construction site ready, blasting, test drilling, landfilling, leveling, earth-moving, excavating, land drainage, and other types of land preparation. Construction Work on preparing the site is important for any project. Before the main building work begins, a construction site needs to be set up.

There may be a lot of obstacles on the construction site, such as old buildings or structures, big trees, sloping ground, loose soil, and underground services. It could cause problems when building. For construction projects to go smoothly, the site must be ready for the building before work can begin.

Introduction
The role of drones in construction is new and something which can bring revolution to the construction world. Earlier all the work had to be executed manually starting from drawing to building houses or detecting structural defects that arise from time to time. All these have been replaced by technology to a large extent. Calculations like building estimates needed extensive time in calculating with the help of a pen, paper, and calculator but now software is available that reduces time and effort for doing cumbersome calculations. Similarly, drones provide various advantages that are beneficial for saving time and labor work. Not only this, accuracy in work increases, and better perception of the ongoing work is facilitated. All the pros and cons along with additional data are discussed here.

Introduction:
The movement of heat across an object that is more conductive than the materials it is surrounded by is referred to as thermal bridging. Heat flows through a path of least resistance created by the conductive material. Thermal bridging can be a significant cause of energy loss in homes and buildings, resulting in increased utility bills. The object’s overall thermal resistance is reduced as a result of thermal bridges. Thermal bridges result in heat transfer into or out of conditioned space and are commonly discussed in the context of a building’s thermal envelope.

INTRODUCTION
Contracts provide a legal framework or a set of protocols to be carried out to establish a legal settlement between the two parties involved. It avoids any such unnecessary confusion that may arise leading to disputes. These are the keys to guide business relationships across all sectors. Not only that, these are helpful for contractors to better estimate the time and money to be used up in the project. Also, it helps the contractors to utilise their powers for gaining maximum profit out of it.

When contracts are not met as per the requirements, then action has to be taken at the initial stages, otherwise conflicts may arise leading to unprofessionalism and disputes. Contracts address labour requirements, incentives involved, money matters, time of delivery, economic construction, choice of equipment, and so on. Thus, it is essential if the construction works are to be carried out smoothly.

INTRODUCTION
For earthwork in excavation, foundation which are symmetrical, brickwork in superstructure and plinth and concrete in foundation, two methods are there for estimation. These are-

1. Separate or Individual wall method and
2. Centre Line Method.

With these methods the lengths and widths of various items are mainly found out which helps in calculations.

Chapter- 1 Introduction
1.1. General:

Mahatma Gandhi envisioned a society where the man would live in harmony with nature. He Propounded having self-sufficient village communities to achieve this goal, having a civilization built on renewable resources. He insisted for the growth of human beings from every stratum of the society and to avoid wasteful use of resources. It is in the Indian culture system to find use for everything, which may be considered as waste by many. However in the race of rapid urbanization and globalization we have lost these practices leading to unsustainable growth of cities.

As per Figure 1.1, by 2008, 30% of Indian population was living in cities generating 58% of the total GDP of India. It is estimated that by 2030, more than 40% of Indians would be living in urban areas contributing to about 70% of the GDP. The cities are going to be the engines of growth for India to become a developed nation and so, the quality of life needs to be improved for sustaining the growth in the long term. India being the second most populated country in the world has some of the most densely populated cities in the world. The rise in Indian economy in the last couple of decades has created many job opportunities in the cities leading to a rapid influx of migrants from the rural areas to the urban areas.
