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.

as we all know that for finding void ratio(e) of a cube, that is vol. of void divided by vol. of solid. so my qus is how we can find vol. of void in a cube??
please do rply.
Thank you.
Its simple, just subtract the volume of solid from the total volume, note that the more you consider the total volume the more is your volume of void. Thus by calculating it you can calculate the Void Ratio
Void ratio *volume of cube
We can find void ratio by testing the soil for specific gravity and water content.There are some relations related to specific gravity and water content to find out void ratio.
BY USING SIMPLE FORMULA OF DENSITY AND SPECIFIC GRAVITY RELATIONS WE CAN FIND OUT VOLUME OF VOIDS FOR MORE INFORMATION REFER B.C. PUNMIA BOOK OF GEOTECHNICAL ENGINEERING CHAPTER PROPERTIES OF SOIL
what are the types of motors used in the construction industry #civil am a student
there are differnt types of mortar are used
1. lime mortar
2. cement mortar
3. fly ash mortar
Universal Motor
Electrically excited DC motor.
Permanent magnet DC motor.
Brushless DC motor.
Switched reluctance motor.
Cage and wound rotor induction motor.
Torque motor.
Ironless or coreless rotor motor.
dear student the types of mortar depend on the various binders used such as cement , lime etc for more information refer building construction textbook by rangwala
This site is really encouraging. But i really need some help, i need a journal or write up for “effect of concrete on the environment”. Thanks…..
thanks,and please keep it up for posting an interesting civil engineering materials,to civilize the world
