Construction Equipment Selection Guide

This document discusses factors that affect the selection of construction equipment and methods for infrastructure projects. It outlines that productivity, total cost, and required time/effort are key considerations. Equipment is categorized into earth moving, vehicles, material handling, construction, and tunnel equipment. Selection is influenced by technical specifications, site dimensions, safety, policies, costs, and environmental impacts. The type and size of equipment depends on the project scope and costs. Durability, workability, disposal costs, and future usability must also be considered. Standard versus specialized equipment advantages are outlined.

CE 752- Construction Methods and

Equipments

Unit - I
1.1 Introduction &
Factors affecting selection of
equipment and methods
Introduction
Factors affecting selection of equipment and methods:
 Mechanization and use of heavy construction equipment is an
important part of modern infrastructure projects.
 The effect on productivity and the total cost incurred
are perhaps governing factors when it comes to selecting an
equipment
 The selection of the appropriate type and size of construction
equipment often affects the required amount of time and effort
and thus the job-site productivity of a project.
Types of Equipments
Construction equipment can be categorized in to 4
main sections based on purpose and use, They are:
1. Earth Moving equipment

2. Construction vehicle

3. Material Handling Equipment

4. Construction Equipment

5. Tunnel Equipment
Factors affecting selection of Construction
equipments:
 Hard Factors - Technical specification of the equipment,
physical dimension of the site, cost calculation

 Soft Factors – Safety consideration, company policies


regarding purchase or rental, market fluctuations and
environmental constraints
 Artificial intelligence based models, dynamic programming
based models, software for crane selection ( compu – crane,
etc.,)
Factors affecting selection of Construction
equipments:
 Type and size of equipment depending upon the project

 Cost and profitability in using the equipment

 Usability of that equipment i.e., wrto future projects


(idling cost, tax and storage cost to be considered)

 Durability, workability and disposability of that


equipment (ex, frequent breakdown should not be there)
Factor No 1: Types of equipments:
1. Standard Equipment
2. Special Equipment
Standard Equipment:
 Equipment which are commonly manufactured and
available to prospective purchasers may be classified as
standard equipment
 Generally, standard equipment will be manufactured in large
numbers
Special Equipment:
 Equipments which are manufactured for use on a single
project or for special type of operations
Ex: Cranes used in Coal mines, Equipments used in Dam
construction
Advantages of Standard Equipment over Special
Equipments:
 Delivery of standard equipment may be obtained more easily/
quickly

 Standard equipment can be used economically on more than


one project

 Repair parts may be obtained more easily and economically


than for special equipments

 Disposal of standard equipment parts is more easy and


profitably
Factor No 2: Cost and profitability:
 Economic considerations such as
Owning costs
Operating labour costs and
Operating fuel cost , are important in the selection of the
equipments.
 Replacement cost of existing equipment, the salvage value and
the resale values are also important
Factor No 4: Durability:
 The ease and speed with which the required parts are replaced
will affect the selection of equipment.
 Down time
 Equipments whose spare parts are easily available should be
choosen.
Criteria for the selection of Equipments:
 Use of available equipments ( from previous projects)
 Suitability of job conditions (soil condition, climate etc.,)
 Uniformity in types (common type of engines for different m/c)
 Size of equipment
 Unit cost of production (economic evaluation – freight, packing,
insurance, erection)
 Country of origin
 Availability of spare parts
 Versatility – std equip – possibility of modifying the parts to suit
the present need
 Selection of manufacturer
 Suitability of local labour
 Adaptability of future use
