VOLUME-III - ESTIMATE OF COST

1. GENERAL

This chapter describes Estimates of Cost for execution of Lower Tizu HEP. Basis

for arriving hourly use rate of the equipment, analysis of rates for individual items

of Civil works and cost of the E&M works is also presented. Quantities for various

items of civil works have been calculated from the design drawings given in

Volume-II for various components of the project.

BASIS OF THE ESTIMATES

The analysis of unit rate for various items of civil works is based on the standard

practices, guidelines and following assumptions.

Guidelines and inputs for préparation of estimâtes for the project issued

by GON and Indian standard IS: 4877.

The analysis of rates for various items have been worked out in

consideration the cost of materials, carriage, handling, storing, labour and

equipment required for various items of work and including overheads.

Overhead charges and contractor’s profit have been kept at 20% in

accordance with guidelines.

The base line of estimates is at Sep 2016, Price level and all costs are

expressed in Indian Rupees.

1.1 E&M EQUIPMENT COSTS

The cost of the turbines, generators and the related electrical and mechanical

equipment for the project has been estimated based on experiences of recent

projects of similar size and design parameters/ Budgetary offer of suppliers. Major

component of the electro-mechanical equipment are:



Turbine, Inlet emergency values Draft tube Gates and Generators;

All Balance of plant (BOP) Electrical Equipments;

All BOP Mechanical Equipments;

Powerhouse overhead crane and Draft Tube Gate Hoist:

Main Power Transformers;

Switchyard equipment and interconnection;

1.2 COMPOSITION OF THE COST ESTIMATE

The project cost estimate has been divided under the following heads in line with

the Guideline for preparation of estimate for river valley projects “issued by CWC

and Indian standard IS: 4877. The cost has been classified into direct and indirect

charges and covered under the following minor heads:

DIRECT CHARGES

A DRILLING & BLASTINGa) Drilling at quarry site is proposed to be carried out with Jack Hammer

(Consider 1 ft drilling is sufficient for blasting 0.59 cu.yd of Rock)

- As per working rate of driiling and blasting with jack hammer = m 44.44 - Add 50% horizontal drilling for pull effect = m 22.22

Total depth of drilling = m 66.66

b) Jack hammer charges per hour = Rs 1,453 Taking rate of drilling as 6 per hour- Cost of drilling = Rs 16,142.24

c) Drilling rod charges per meter = Rs 74.00 Drilling rod charges = Rs. 4,932.84

d) Blasting - Explosive

Rate of Explosive per Kg = Rs 100.49 - Explosive req. for 100 cum rock (0.43Kg/cum.) = Kg 43.00 - Cost of gelatin = Rs 4,321.24

e) Blasting - Detonators- Average depth of hole = m 1.75 - No. of holes = m 38 - No. of detonator used, when 1 detonator used for 1 hole = m 58 - Cost of one detonator = m 27.13 - Cost of detonator = Rs 1,573.77

f) Blasting batteries, primacord and loading wire etc.@ 15% of the cost of gelatin = Rs 648.19
