Introduction
In civil engineering, construction actions are usually ones performed in single units in the
process of gaining overall development structures. This paper is based on the understanding of
such dissimilar tasks and information necessary in the growth of a huge construction which has
been proposed to be effected in Lok Wo Sha, Shatin, Hong Kong. This is going to be exposed in
the following sections.
LO1: Explain the common method and techniques used in civil engineering earthworks
and substructures
Task 1a: Earthworks activities, equipment and techniques
Excavation and earthmoving equipment.
They are discussed as follow;
Bulldozer: Used for pushing the soil in the effect of excavation.
Dragline: Used in the progress of the heavy excavation.
Dump Truck: Used in transferring the excavated material.
Excavation
Refers to the process that entirely aid during the process of breaking the rocks and the soil into
smaller parts (Navon, Khoury and Doytsher, 2012).
Excavation and load
The vehicle load comprises of both dynamic and the static loads, administered as a result of the
quarter-truck model support.
Haul and deposit
These processes involve the construction and drilling tasks. The task is carried out using,
bulldozers, cranes, leaders, trucks and tractors.
Task 1b: Methods and techniques used in the creation of piling works, complex foundations and
the drainage works
Some of the stages being taken in the development of the foundation are highlighted below:
 Inspecting the soil in which the development of the foundation ids to effect.
 Finding actual turnings of the foundation over the inspected soil to enable development
of this proposed foundation.

 In increasing the net carrier processing through conducting the entire excavation process.
 Footing installation.
 Sealing footing so as to avoid interaction with moisture (Rezkhikha, 2019).
Task 1c: The techniques and methods used in the construction of culvert, underpass and utilities
provision.
Among the aspects determining development and construction of these features are as stated
Weight angle dropping: n the process of ensuring that the hammer is striking the required head,
a hammer with the estimated pile weight is dropped from an appropriate height carefully guided
and freed to the ground.
Vibration: The hammers used are established and are electrically powered. They comprise
contra-rotating masses that are eccentric embedded in the housing. This housing is attached to
the head of pile.
Jetting: Jetting entirely helps in the process of marinating the pile penetration in the sand to be
used (Chew, 2017).
Culvert Construction
Steps:
•The construction of half culvert is accomplished through excavation carried out as designed
•The bed of the culvert then prepared.
•Screed concrete with the rubble wall are placed (Agarwal, 2017).
• Traffic diversion is then carried out.
Construction of Underpass.
Refers to the development and construction of passageway or tunnel based way running beneath
a railway or road mostly to be used by pedestrians.
