    ABSTRACT

    The Student Industrial Work Experience Scheme (SIWES) as intended by Nigerian

    Government was introduced as a means to skills-training and competence-building

    intervention for students of tertiary institutions. SIWES was established in 1973 by the

    industrial training fund ITF. This was a reaction to the directive given to ITF through

    Decree 47 of 1971, charging it with the responsibility of promoting and encouraging the

    acquisition of skills in industry and commerce with the view to generating a pool of

    trained indigenous manpower sufficient to meet the needs of the economy.

    SIWES has the potential of increasing the scope and variety of technical skills in the

    common phases for the industrial, technological and economic development. The

    projected stakeholders in the SIWES project include the students, institution and

    employers (the attachable organizations and companies). This basically is expected to

    enhance full participation and cooperation of the stakeholders and also, minimizes the

    gap between theoretical knowledge acquisition and the practical experience of

    students. Participating in this scheme is a valid requirement to meet BSc. (Hons) award

    for Civil and Environmental Engineering.

    Obviously, Entrepreneurs engaged in Civil and Environmental Engineering works (design

    and construction) have made available privileges to intending students to get attached

    to their establishments in order to make realistic the vision of the Nigerian Government.

    The scheme has not only improved local content participation but also has created job

    opportunities to students who are diligent in their doings while on the scheme.

    This is a report aimed at briefing my experience while I was involved in The Students

    Industrial Work-Experience Scheme (SIWES) and what I think could be done to improve

    the scheme. I was taught and engaged the basic stages involved in the design of a

    structure (which involves the breaking down of the structure into panels), preliminary

    design (which involves estimating the sizes of the members and checking if they will

  • Opawole T.M 171012

    7 | P a g e

    satisfy both ultimate and limit state design criterion), final design involves the analysis

    and design of the structure. I was taught how to design and model a structure using

    softwares like Ms-Excel (spreadsheet), AutoCAD, Orion, Beamax, and ETABS, without

    leaving out guidance on basic detailing strategies. The softwares earlier stated are

    priorities in various Civil & Environmental Engineering works.

    This report comprises of four chapters: chapter one is introduction and briefs of SIWES

    and company profile, chapter two contains the design experience acquired, chapter

    three further showcase the site experience acquired while chapter four is conclusion

    and recommendations.

    CHAPTER ONE

    INTRODUCTION

    1.0 SIWES: Students Industrial Work Experience Scheme:

    SIWES a scheme by ITF Industrial Training Fund was established in 1973 to solve

    the problem of lack of adequate practical skills preparatory for employment in

    industries by graduates of Nigerian tertiary institutions. SIWES is intended to expose

    technical undergraduates basically to industry based skills necessary for a smooth

    transition of knowledge from the walls of their schools to the realm of professional

    practice. It radically encourages students technical undergraduates of tertiary

    institutions to initial handling and use of industrial machineries, tools, instruments,

    wears and realistic visits to sites related to their courses of study. This as expected

    enhances further understanding for all participating to students as they engaged a

    more advanced level of study in their fourth and final year as an undergraduate.

    With this Scheme Nigerian academic standard is made real and feasible.

    Participation in SIWES is as of now a compulsory criterion for the award of Diploma

    and Degree certificates in specific disciplines in most institutions of higher learning

    in the country, in accordance with the education policy of government.

    AIMS OF SIWES

    Lightly listed as:

    I. Availability of practical skills, understanding and experience to students in

    their respective fields.

    II. Platform for creativity with ability to explore options in solving problems

    and achieving success in the participating students.

    III. To subdue professional fear and improve confidence of students in their

    line of study.

    IV. To improve the quality and reasonability of students being discharged to

    the nations workforce at the end of their undergraduate study.

    CHAPTER TWO

    PROJECTS ENCOUNTERED: Design

    During my stay at REDGREY ASSOCIATES (RGA), I was exposed to Civil Engineering

    consulting business prosper. The firms operations comprise of structural design and

    site supervision of Civil and Environmental projects; Development of Pan-Atlantic

    University (PAU) undergraduate site located at Eleko along Lekki-Epe expressway is one

    of the firms major projects.

    I got acquainted with the firms mode of operation the Phase I and Phase II stages of

    design; Once the firm is commissioned for a project and architectural drawings received

    in both hard and soft copies, the Phase I design stage commences. A preliminary design

    is carried out which entails load estimation based on BS 6399, and preliminary sizing of

    structural members with reference to Table 3.19 BS 8110-1:1997. From the foregoing,

    the approximate overall weight of the building is estimated. The ultimate design load

    (n) of each floor is summed up including the roof load in kN/m2 to obtain the total

    weight of the building which is thereby divided by the building area to obtain the total

    weight of the building in kN/m.

    The above information is made available to the geotechnical engineering company

    which therefore carried out geotechnical investigation to obtain subsoil and ground

    water conditions of the site. A comprehensive report is therefore prepared based on

    acquired information from the geotechnical investigation. The report provides

    information about the geological settings of the site, soil profile, ground water level and

    recommendations on the type of foundation to be adapted based on the weight of the

    building estimated by the structural engineer.

  • Opawole T.M 171012

    12 | P a g e

    RGA therefore prepares sets of structural drawings (stamped) based on preliminary

    design made previously which is sent in conjunction with architectural, electrical and

    mechanical drawings to Lagos State Building Control Agency for approval. The structural

    drawings contain Foundation Layouts, Ground floor and other floors layouts with piece

    by piece detailing of all structural elements. The Layouts/General arrangements show

    beam and column sizes, slab thickness and levels with reference to setup datum. The

    structural layouts were modeled analyzed with Orion RC design software.

    In the Phase II design stage, the structural layouts were modeled, analyzed and

    designed in ETABS. The results of the analysis and area of steel provided by ETABS were

    exported to Excel spreadsheet. A graph showing the reinforcements required for all

    beams were generated using PIVOT CHART in Excel, this was used to properly detail the

    beams. The beams elevations were imported via DXF from Orion.

    This firm uses two softwares: Orion and Etabs to achieve their analysis and design.

    The followings were some of the aspects of works I participated in:

    I prepared bending schedules of beams and columns using AutoCAD.

    I was involved with a follow up of strip foundation design of School of Media,

    Pan African University, Ibeju-Lekki campus. It was modeled and designed

    using structural design software ETABS, it structural analysis principle is

    based on finite element method of analysis. The foundation provides for a

    suspended ground floor carried by 900x230mm ground beams and

    400x300mm suspended beams having concrete characteristic of fcu= 21

    N/mm2.

    I was involved in the modeling of PAU students centre building with Orion and

    Etabs.

    I designed and detailed the first floor and roof slabs of the above mentioned

    project.

    I carried out preliminary design and preparation of structural layouts for an

    office complex located at Cheveron roundabout along Lekki-Epe express way.

    I compiled in PDF format and print out drawings for an already completed

    project in Ajah. The drawings were submitted to the Quantity Surveyor for re-

    measurement of the work done on the site.

    CHAPTER THREE

    PROJECTS ENCOUNTERED: Site Works

    Construction of building involves many different trades, materials, operations, and

    schedules that must be properly managed in order to meet a budgeted amount or time

    period expected for occupancy. A general contractor is selected and awarded the

    contract to construct and build to clients specifications. The construction process is

    often wrought with uncertainty and unpredictable events, but once everything is

    completed, a sense of satisfaction (and relief) is had by all.

    The role of a structural engineering firm is an integral part of a construction process,

    which includes preparation of construction drawings after rigorous calculations had

    been done and supervision of works carried out by the general contractor.

    During my SIWES, so many construction projects were on-going. Which are: PAU

    Academic complex, PAU students Centre, Lagoon Hospitality Unit and Dining Extension,

    Enterprise Development Centre (EDC) and the PAU Male Residence. Site meetings were

    held fortnightly for each project. At the meeting, different consultants meet to discuss

    technical issues as regard the project. The meetings were being head by a Project

    Manager which is usually an Architect, clients representative, the structural

    engineering consultant, Quantity surveyor, Mechanical and Electrical consultants and

    the general contractors team.

    Before every meeting, the site is briefly inspected and issues are being raised on any

    aspect of work that are not to specifications and the structural engineer in-charge of the

    project issues an instruction to the client which is properly documented for future

    reference in case the general contractor do not follow the instructions. The site meeting

    is a tool used by the PM to track the progress of work, identify problems that can cause

    delay, provide solution, assign responsibility and give a time-line to all tasks.

  • Opawole T.M 171012

    20 | P a g e

    Apart from the regular site meetings, the general contractors do schedule site

    inspection with the structural engineer prior to the casting of any structural elements.

    During the inspection the following were looked out for:

    Drawings: it must be approved and current

    Formwork: shapes, size and level must conform

    Reinforcement Bars: diameter, numbers, spacing, shape, length, positions and

    conditions as regard corrosion.

    Concrete cover: as specified in the drawing. It must be minimum

    Cleanliness: the site is also checked for any form dirt that can affect the quality

    of concrete to be poured by the general contractor.

    Opening for concreting: the rebars must not be congested that will affect

    concrete pouring and cause voids in the structural elements after casting.

    An Engineers Instruction is issued to the general contractor stating that the contractor

    can proceed to pour concrete depending on if the above mentioned items and

    acceptance criteria are met and if not, Instruction is issued for remedial actions.

    The followings were some of the aspects of works I participated in:

    I was taught to identify bar sizes and their numbers.

    I was involved in the counting of stirrups and spacings fixed in beams

    I measured formwork depth check for concrete cover.

    I helped to read drawings and determined if there is any issue.

    One experience worth to mention was columns which the concrete strength did not

    conform. The concrete design characteristics strength is 21 N/mm2 while the value

    obtained after crushing the test cubes samples at 28 days was 11 N/mm2. The general

    contractor was summoned for a meeting and RGA team of engineers provided remedial

    action to salvage the situation. The design loads (N) on each column were used to

    redesign the columns with an fcu of 11 N/mm2, this result in increasing the cross-

    sectional area of the concrete in order to increase the carrying capacity of the column.

    The general contractor was made bear the cost of the repair works.

    To rescue the situation, the surrounding beams and slabs of the columns were properly

    propped and the existing columns were bush-hammered to expose existing

    reinforcement bars. New reinforcement bars welded on steel plates (longitudinal and

    stirrups) were provided and installed. A new formwork was built up and concrete was

    poured thereby increasing the columns section.

    CHALLENGES ENCOUNTERED

    I will like to make known a few of the challenges I encountered while at duty during my

    participation in SIWES.

    They can be described thus;

    The first and basic challenge I had during this program was the creation of office

    relationship which seems to be due to age and qualification differences, at about the

    first one week of the program.

    At the time of visiting PAU project, I got uneasy over time of travel and the expanse of

    site we had to walk through because the project vehicle could not navigate all parts of

    the site.

    Though, I was good with the use of AutoCAD software I found out I was to an extent

    slow due to the pace at which work is done and expected at the office.

    So, I decided to always ask questions on how to be fast with the software and also with

    the use of shortcuts on the program.

    The office (supervisors) never made my challenges my problem but took time to help

    me overtake them. They made the use of structural engineering softwares easy for me.

    CHAPTER FOUR

    CONCLUSION AND RECOMMENDATIONS

    I wish to conclude this report with the opinion that the Industrial Work Experience

    Scheme has proved inestimably value in helping me appreciate the professional

    relevance of the theoretical knowledge acquired in my course of study over the

    years. The scheme also, to me as a Civil engineering student has encouraged

    practical applications of structural terms in reinforced concrete and steel design

    alongside relevance of subsoil investigations and various types of foundation.

    The scheme has obviously introduced all stages/phases and part skills of Civil

    engineering design and construction to me in a stretch of just 7 weeks.

    Based on the acquired experience in Civil Engineering Consulting and project

    management, I will like to write that the following should be more focused on if

    existing in the academic curriculum, if not should be introduced.

    This opinion includes:

    Introductory courses on professional human relation and resourcing should be

    offered to undergraduates as early as possible in their academic years.

    The practical aspects of our theoretical curricula should be properly adhered to

    such that it becomes part of us.

    Enlightening courses on project management and perhaps business/marketing

    engineering should be encouraged as a criterion to having a certified degree. This

    will in a way help displace to extremity unemployment.

    Finally, I wish to recommend that participating institutions should enforce the

    supervision aspect of the program to ensure students sincerity to the scheme.

    I think SIWES would be much more effective if silent observers are positioned in

    various organizations to give an accurate evaluation of the working style and

    situations of its SIWES students.
