ABSTRACT
The size of the Nigerian construction industry is relatively small as compared to other
sectors of the economy. In 2008, the industry made up to 0.2% of the value of the global
construction industry which was about $3.15bn. It has also out grown some other sectors with an
impressive percentage of 12.1% despite the fact that its growth is directly and indirectly linked to
the government expenditure on infrastructure in 2005 (Dantata and Sowe, 2008).
The quantity surveyors as a chartered professional are not left out in this trends of emerging
development. The profession has evolved from been a craft to a well-respected profession today.
The contribution and services offered by quantity surveyors in the construction processes are
increasing rapidly in scope and size. The expectations chain of quantity surveyors has also
increased in length as a result of introduction of modern technologies, complicated client, and
emergence of new rules and regulations. Therefore, in order to remain active and maintain a
competitive edge among other professionals, quantity surveyors need to diversify their
contributions and services towards the success of any construction activities in the industry.
My scope of knowledge has become wider as I came across most of the activities that were
being taught in the classroom environment and in the construction textbooks at Quintec Limited.
I participated in many of the activities during my S.I.W.E.S training which cut across office
activities and site activities. Office activities includes; preparation of material schedule,
preparation of interim valuation, preparation of programme of work using Microsoft Project,
preparation of rain chart, among others while site activities I observed includes; sand-filling, pile
foundation construction (pile cap, ground beam and slab), pit excavation for services, Installation
of mechanical and electrical pipes (MEP), site inspection as well as drawing interpretation. Hence,
this report is the summary of the experience and skills acquired.

CHAPTER THREE
3.0 INDUSTRIAL TRAINING EXPERIENCE
3.1 Overview
In all, I have been trained as to be equipped in the construction industry as I was exposed to various
facets of building profession which deals with general site concept and contractor/consultant
interface.
Construction involves a lot of professions like Quantity Surveying, Architecture, Structural
Engineering, Electrical Engineering, Mechanical Engineering, Surveying, etc. all of which a
Quantity Surveyor must be exposed to. I was exposed to all of this profession interfaces as far as
building construction is concerned. The details of what I went through is subsequently explained
as follows:
3.2 Office Experience
3.2.1 Detailed Drawing Study
I was taken through the detailed study and interpretation of the first three drawings (as listed below)
and was introduced partially to the fourth and fifth as this act result into an excellent construction
work and ends with “as prescribed” project delivery.
(1) Architectural drawing
(2) Structural drawing
(3) Mechanical drawing
(4) Electrical drawing
(5) Others (Security and ICT)
Architectural Drawing
The architectural drawing has been breakdown into elements as compared with the available site
condition provided and it is called construction drawings. I was able study the architectural
drawing efficiently.
12 | P a g e
Figure 4: Sample of The Architectural Drawing for Faculty
Structural Drawing
The structural drawing consists of various structural element of a building such as piles, pile cap,
lift wall, beam, slab, column, etc. It shows the reinforcement details. It is usually prepared by a
Civil Engineer. They use software such as Orion, AutoCAD, Civil 3D, among others to prepare
this document.
As an intern, I was made to study different structural elements details like slab, beam,
columns, and pile cap (the gridlines, identification of the bars arrangement on the section and
interpretation of bar codes on the sections, calculations involving lap length, length of bend, etc.).
I was also taught how to measure these structural elements. These elements consist of concrete,
formwork and reinforcement. They are measured in the following ways;
i. The concrete is measured in cubic metres
ii. Formwork is measured in linear metres or square metres in accordance with the BESMM
4 (Building and Engineering Standard Method of Measurement Forth Edition) which states
13 | P a g e
that when the height is less than 1m it should be measure in linear metres and when greater
than or equal to 1m it should be measure in square metres.
iii. Reinforcements is measured in linear metres and then converted to Kilograms or Tons
using certain multiplying factor which is not the same thing for all bar sizes. Below is a
table showing the multiplying factor of various bar;
BAR SIZE (mm) WEIGHT
(Kg/m)
PERIMETER (mm) NUMBER OF BARS (No)
6 0.222 18.05 376
8 0.395 25.10 211
10 0.616 31.40 136
12 0.888 37.70 94
14 1.209 43.98 69
16 1.579 50.27 53
18 1.998 56.55 42
20 2.467 62.83 34
22 2.985 69.12 28
25 3.854 78.54 22
28 4.835 87.96 18
32 6.315 100.53 14
40 9.867 125.66 9
Table 1: Details of Reinforcement Bars
The standard length of a typical reinforcement is 12 metres and they often come in different sizes
like 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm and
40mm. The number of reinforcements in a tons of reinforcement is calculated using the following
steps;
Step 1: Determine the weight per metre of the reinforcement in consideration
Step 2: Multiply the weight by 12 metres to get the weight per 12 metres
Step 3: Since 1 ton = 1000kg, then divide 1000kg by the resultant value gotten in Step 2.
Important formulas to note when dealing with reinforcement;
1) Conversion from metres to kg in circular sections = × × . ×
2) Conversion from metres to kg in square sections = × ×. ×
14 | P a g e
3) Number of reinforcement = ()
× ()
Mechanical Drawing
The Mechanical drawing consists of various mechanical elements of the building such as lift, water
storage facilities, waste disposal systems, etc. It shows details such as position and components of
water closet, lift, wash hand basin, floor drain, waste water pipe, fresh water pipe, soak-away, cess
pool, bore hole, fountain, among others.
As an intern, I was made to study different mechanical elements details like water closet, wash
hand basin, pipes, floor drain, etc.
Figure 5: Mechanical Drawing
Electrical Drawing
The Electrical drawing consists of various electrical elements of the building such as lighting point
and types, sockets, switches, wires/cables, distribution box, meter, earthing rod, conduit, etc. It
shows details such as position and components of fans, sockets, switches, earthing rods, wires,
among others.

3.2.2 Software Appraisal
I was privileged to be exposed to some softwares used in the industry which includes;
a) Microsoft Excel,
b) Microsoft project,
c) Auto-Cad, and
d) Microsoft Visio
Microsoft Excel
Microsoft excel exercise is a software/spread-sheet program that is used to produce tables, charts,
calculation exercises, graphical representation of data, mathematical computation, etc. It is one of
the major key tool of Quantity surveyor as it is used to prepare documents such as bill of quantities,
interim valuation, financial statement, bar bending schedule, material schedule, etc. I was given
assignments on bar bending schedule, bill of quantities, interim valuation, financial statement,
approximate cost computation, among others.
Figure 8: Interface of MS Excel
17 | P a g e
Microsoft Project
Microsoft project is project planning and scheduling tool. It is an important project management
tool which is one of the major function of a quantity surveyor. It is used to prepare programme of
work, manage resources, etc. I was given an assignment to prepare programme of work for a
various residential project.
Figure 9: Interface of MS Project
AutoCAD
AutoCAD is a CAD (Computer Aided Design or Computer Aided Drafting) computer software
used by designers in producing working drawings. This software can be categorized into two types
that are 2D draughting system and 3D draughting system. As for QS, CAD software brings
benefits to QS in the preparation of BQ. Nowadays, with the existence of CAD software had
replaced the traditional method of BQ production. This software may serve to measure the
quantities directly from digital drawings. My first assignment on AutoCAD was to design a room.
18 | P a g e
Figure 10: Interface of AutoCAD
Microsoft Visio
Microsoft Visio is a software used to draw site organogram, layout of buildings, layout of electrical
works, network diagram, flow chart. As a Quantity surveyor, I used it to design the site organogram
for the project.
Figure 11: Interface of MS Visio
19 | P a g e
3.2.3 Interim Valuation
Interim valuation is a document usually prepared by a QS on regular basis which can be usually
monthly. It is pre-cursor to the issue of an interim certificate, which in turn allows an interim
payment to be made. It is a detailed breakdown, generally prepared by a contractor, that constitutes
an application for part payment of work undertaken since the last valuation.
It consists of builder’s works, advance payment, retention, material on and off site, preliminaries,
etc. as the case maybe. There are two ways measuring workdone which are namely; physical
measurement method and percentage method. In the physical measurement method, the QS goes
to site to carryout actual measurement of the workdone while in the case of percentage method,
the QS measure the workdone on percentage basis. As an intern, I was given an assignment to
prepare an interim valuation for a project.

3.2.4 Taking Off
Take-off can be defined as the process of extracting dimensions from drawings. I learnt how to
measure quantities using MS Excel and AutoCAD. I was also exposed to the measurement of piles,
pile cap, complex ground slab, lift base, etc.
Figure 13: Using AutoCAD to measure
3.2.5 Technical Site Meeting
Technical meeting holds on weekly basis. The contractor and consultant come together to discuss
problems encountered on site and possible solutions. I was privilege to attend these meetings and
I gained some experience concerning contractor to consultant relationship, professional ethics,
among others.
21 | P a g e
Figure 14: Technical meeting on the progress of the project
3.2.6 Arithmetical Check on Tenders Received
Tenders received often times contain some errors, these errors are due to omission, posting,
commission and so on. Multiplication errors in a bill page are termed extension error, while for
addition of amount of various item is termed Summation error. If errors are discovered after the
contract has been entered into may lead to dispute and so as a trainee at QUINTEC, I was
competent enough to discover the mistakes committed each time.
I got to understand how these mistakes are discovered. Firstly, the rates of tenderers are acutely
checked so as to ensure consistency. secondly, computational check is carried out by multiplying
the rates by the quantities so as to confirm the amounts which are thereafter added up confirming
the totals carried to collection and then, summary.
Also, anything item wrongly calculated either intentionally or unintentionally, will be recorded
and the parties involved will be notified.
22 | P a g e
3.2.7 Material Scheduling
Material scheduling is the systematic breakdown of quantities to material terms. It involves the
use of material constant to generate. It is a detailed list of construction materials required for a
specific job. I used a material constant table to generate list of materials for several projects.
Below is a table showing the different grade of concrete which is important during concrete
material estimation and based on trial mix;

3.2.8 Labour Productivity Study
As an intern, I noticed the productivity of labourers’ in the Hostel building is higher than that of
the Faculty building. I carried out a productivity study research to study the factors responsible by
sampling the labourers’

3.2.9 Rain Chart
Rain chart is a chart that is used to record the duration of rain fall on regular basis which is usually
monthly. I learnt how to prepare rain chart template and how to track it using MS Excel. As a
Quantity surveyor, rain chart is very important in terms of time extension claims. If there’s a
detailed rain chart, the contractor can use it as a basis for time extension.

3.3 SITE EXPERIENCE
The site experiences acquired are as follows:
- Surveying exercise;
- Assessment of the delivery of ready mix concrete to site;
- Felting to lift well;
- Slump test exercise
- Pile foundation construction
SITE
EXPERIENCE
SNAPSHOT DESCRIPTION
Surveying exercise
I learnt how to use total station to
get column point and transfer
point. Total stations contain
algorithms that calculate and
display the horizontal distance
and vertical height. They are
used for trigonometric levelling,
locating positions, etc.
Assessment of the
delivery of ready
mix concrete
I learnt how to record the
deliveries of ready mix concrete
whenever they come to site to
delivery concrete for works.
26 | P a g e
Felting to life well
I learnt the various processes of
laying asphalt felting to a lift
well. First of all, the water in lift
well was drained then the
asphalting felting was placed on
the walls and floors of the well
and heated to bind them together.
Slump test exercise
I learnt how to perform slump
test exercise. Firstly, sample is
collected from the truck then
poured into the slump formwork.
The concrete is then compacted
25 times in each of the three
layers making a total of 75 times.
The slump formwork is removed
gently and placed beside the
concrete and a straight iron rod is
placed on the slump formwork
which is used as a reference
point for measurement. The
measurement is obtained using a
ruler placed at the highest point
of the concrete to the straight
iron rod.

Pile foundation
construction
I learnt the construction process
of constructing a pile foundation
and identification of various
component of a pile foundation
such as pile, pile cap, ground
beam, and ground slab. The
building loads are transferred to
the ground slab then to the beams
then to the pile cap and finally to
the piles which transfer it finally
to the hard strata which carries
the load.
Curing of concrete
I learnt how to cure concrete,
after casting, the concrete will be
covered with hessian sacks to
reduce the rate of evaporation
and retain water. Water is then
poured on the concrete for 3 days
consecutively.

4.0 GENERAL
I was exposed to various experience such as construction and measurement pile foundation,
preparation of interim foundation and financial statement, preparation of programme of work using
MS Project, preparation of bill of quantities and take-off using MS Excel, preparation of
organogram using MS Visio, preparation of simple drawings and measurement using AutoCAD,
etc.
4.1 Site Inspection
This is the act of the professionals on the project to check whether the conceived ideas put on paper
are translated into real structure. A Quantity surveyor must ensure that the project is well
constructed according to the drawings, bill of quantities, and the specification with respect the
program of work to avoid cost overrun and maintain project budget.
4.2 Challenges On Site and Off-Site
Just like every other endeavour of man, the SIWES experiences came along with its challenges
too and below are a few of them:
1. The first major challenge faced by me during the internship was that of familiarisation, i.e.
getting to know the work environment and colleagues, knowing their approach to work and
ethics;
2. Another significant challenge that was faced by me was adhering to the resumption time
which was 8am. Considering the unavoidable traffic faced along my route;
3. Being able to cope with the harsh weather condition while going to site; and
4. Ability to multitask.
4.3 Relevance of The Training to Quantity Surveying
Quantity surveying profession exists to ensure the judicious allocation of the construction
resources of materials, manpower, machinery, money, methods and management with the
overriding aim of ensuring value for money spent on construction projects. Alternatively, Quantity
surveying is a professional in the construction industry that deals with cost related issues. Relevant
courses to achieve this are usually taught in the higher institution through class room lectures and
29 | P a g e
practical courses. But, due to time constraint and absence of real life situations these trainings
don’t give the complete experience needed to make a complete building. However, internship is
very important so as to equip the student with the basic practical knowledge and ethics to keep
moving in life.
Through the internship, I was able to apply some of the theoretical knowledge gathered over the
four academic years.
4.4 Conclusion
In conclusion, I have been able to see the practical side of my course of study. Through the training
I was able to attain a greater understanding of how to; prepare material schedule, prepare program
of work for construction project, prepare interim valuation, prepare bill of quantities, use various
software packages in relation to QS function, etc. I also learnt some professional ethics and how
to manage relationship between clients, consultants and contractors.
4.5 Recommendation
I recommend that the internship programme should be encouraged and continued in all tertiary
institutions in Nigeria. And also that it should not just be made compulsory in the penultimate year
to the completion of speculated academic years (as it is in our school, i.e. year four).
It would also be expedient if companies especially the established private ones’ form partnership
at intervals with tertiary institutions in our nation through which they can take on students for
internships in their fields.
