CHAPTER ONE 1.0 INTRODUCTION
1.1 BACKGROUND
Uganda as a developing nation has many projects in the construction industry in order to meet an indispensable desire and need for better facilities. The construction sector is booming and growing very fast with many construction projects involving construction of commercial structures like factories, shopping malls, hotels and residential houses among others. In Kampala district alone, the Kampala city council (KCC) approves an average of 880 building plans per year most of which are implemented.
To implement these projects, there is always need for land, materials, funds and most of all human labour to do the actual construction of these structures. And for the projects to be successfully done within a contracted period, the engaged labour needs to work without much disturbances and harm up to the end of the project, hence prevalence of a safe working environment at construction sites is vital so as to ensure that no or at least minimum accidents and injuries to the workers occur, as this can lead to negative impacts on the projects.
Many construction companies ranging from small to big are involved in provision of services in the construction sector hence a project owner (client) normally has a big sample to choose from thus sets the criteria for selection of a company to engage on his job. Over years, the common trend for selection has been mainly to consider the capital base of the companies, experience in doing similar jobs, personnel and number of jobs done as the priority parameters.
The issue of a company’s record in providing a safe working environment at its construction sites has not been much of selection consideration for jobs yet, it is clearly known that human labour will always be needed on all projects hence the need to have them safe all the time while at work on any project.
1.2 PROBLEM STATEMENT
The construction sector in Uganda is growing very fast, however workers at many construction sites, operate in unsafe working environment, hence there is need to make construction sites safe in order to ensure the safety of workers, if the construction sector is to have a sustainable growth and develop.
1.3 MAIN OBJECTIVE
- The general objective is to assess level of safety of workers at building sites in Uganda and find ways how this can be improved.
1.3.1 Specific Objectives
- To assess the level of provision and enforcement of use of safety gear at building sites.
- To assess the safety of the working environment of building sites
- To assess the level of preparedness and responsiveness of contractors to accidents which occur at their building site within their area control.
- To develop a process of determining the level of safety of a building site in Uganda
- To develop a site safety evaluation tool and company classification system based on safety performance and how to use it at pre-qualification stage for a job.
1.4 SCOPE OF STUDY
The study is will be at selected construction sites around Kampala district covering small, medium to big projects and will be limited to on going projects. It will look at the extent to which the safety of the workers is catered for and implemented at various construction sites but, restricted only to safety measures currently in use by companies, the capacity and level of preparedness of companies and sites so as to avoid occurrence of accidents and their responsiveness when they occur at their sites.
1.5 METHODOLOGY
- Comprehensive literature review on already published work from national and international reports, journals and papers so as to develop initial lists of critical areas in regard to safety issues in Uganda’s construction (building) industry.
- Gather data from the field using questionnaires to contractors and workers.
- Oral interview and dialogue with company management, workers at various construction sites.
- Analyze the collected data using SPSS
1.6 SIGNIFICANCE OF THE RESEARCH.
The intended outcome of the research will be to:
- Improve safety awareness among people at the center of influencing the direction of state of affairs in the construction industry.
- This research may also serve as reliable material source to the policy makers when drafting appropriate regulations and enforceable laws to be applied at building sites especially the promised bill to be presented in parliament setting the standards for construction
- Develop a system of determining the safety level of building sites in Uganda, and use “provision of a safe working environment” by a company as an alternative basis for the classification of companies in Uganda. This will be recommended as a major consideration when evaluating bids and awarding projects as opposed to using other parameters like volume of work done, number of projects handled, or working capital of a company. Since a company with a big capital base but with a big likelihood to impair or even cause death to its employees by not providing a safe working environment is after all no good for the sustainable growth and development of the construction sector.
1.7 CONCLUSION
The research is to contribute to strengthen the safety awareness, response, improvement and assessment of safety issues countrywide at building sites.
CHAPTER TWO 2.0 LITERATURE REVIEW
The literature review has been summarized into sections as detailed below.
2.1 BACKGROUND OF SAFETY
The construction sector in Uganda is undergoing irreversible transformations and fast growth which is reflected by a consistent growth of the sector in the last 17 years, with the current growth rate standing at 16.4% which is even higher than the average national economic growth at 6% as per the national budget of 2004/2005.
This fast growth of the sector has seen the spring up of many construction companies and a big shift in the labour force from other sectors into the construction sector. However, the Local Construction Industry (LCI) is weak, undeveloped, not well organized, and faced with many problems ranging from managerial to technical and lack of access to credit facilities.
It is less prepared and has not built enough capacity to effectively receive, handle, organize and cater for the influx of labour force as pertains their welfare, job tenure, health and most especially their safety when at work.
There is also no systematic way in place to assess and determine the safety level of construction sites, let alone a classification system of construction companies based on how safe they run their sites. Besides there is no single unified Body/Authority in place to guide, monitor and regulate the operations of the construction sector especially to enforce the of provision of a safe working environment and the safety of workers at all times on construction sites countrywide as is with other sectors which have agencies to oversee their operations like the National Environment Management Authority (NEMA), National Forest Authority (NFA), Electricity Regulatory Authority (ERA).
Individuals employed on construction sites in Uganda often find themselves confronted with dangerous, life-threatening working conditions on a daily basis and serious accidents and injuries resulting in personal injury and wrongful death are occurring at alarming frequency at construction sites throughout the country. Although the actual number of all individuals who die or injuries in such accidents is not recorded, there is no doubt that the frequency and severity of construction accidents will increase and prevail unless something is done to check the current unsafe working environment and improve the safety of workers at construction sites.

Photo.1 Bad behavioral attitudes towards safety on site
The worker in the photograph 1 above show bad behavioral attitude towards safety in the following ways:
- The worker is using ladders for a task meant to be done by scaffolding.
- The worker has is relaxing at workplace in a dangerous location and position instead of a restroom.
- There are no guard rails in the place to stop the worker of falling situation.
- The worker has no basic personal protective wear in use.
- The work platform is inadequate as there are very few boards which lead the worker to easily fall through.
- All in all this workers shows little regard to promoting of his own safety while at work.
2.2 ACCIDENTS ON BUILDINGS
2.2.1 Recent Occurrences
Already many site accidents have occurred some fatal. The According to New vision of Sept 1, 2004 a multi-storey building under construction at Bwebajja site 20 kilometers south of Kampala, over 50 workers were buried under rubble. This resulted in the death of 11 workers, and many others were physically impaired and many may never be able to regain their former working capacities.
The ultimate consequences of all this is loss of vital human resource, delays in works and increase in project costs. It is worth noting that it takes a lot of time and resources to train technocrats and impart apprenticeship skills onto these craftsmen and experienced casual labourers. So a loss of any of these lives sets the country and in particular the construction sector many years back, since there are very few of them in our country.
Documented work on construction sites where safety of workers is highly prioritized and enforced has proved to scale down on the number and severity of site accidents worldwide, like in the construction of the former World Trade Center - a multi storey building which had over100 storeys in United States of America, only 4 lives were lost.
In Ugandan, during construction where safety measures were emphasized like in the construction of Kasese Cobalt Company Limited (KCCL) factory in Kasese, the number and severity of site accidents were small as well. It would seem quite difficult to provide a totally safe working environment in the construction industry in Uganda however, as shown by the KCCL experience, a modest safe working environment is achievable which has got striking advantages like easing site management, maximizing utilization of resources, helps in evaluation of growth and performance of the construction sector.
2.2.2 What Has Been Done
Of late, the safety of workers at sites is gaining a lot of credence in Uganda with the minister of housing & communication promising to introduce a bill in parliament setting standards for construction, however prior to that, much needs to be done to gather all the possible data and alternatives that can be adopted to achieve this.
Debates on occupational safety and health have intensified following reports of accidents at construction sites, reviewing existing regulations so as to cater for today’s requirements and strengthen them.
The department of Occupational Safety and Health in Uganda’s ministry of Gender Labour and Social Development recently organized a workshop aimed at sensitizing and bringing forth standing industry guidelines on occupational safety and health in the construction industry. The workshop focused on a number of areas of critical concern to the building and construction sector in Uganda notably:
- Plant and equipment on building and construction sites and statutory requirements;
- Safety policy and Programme in building and construction industry;
- Subsidiary legislation and general occupational safety and health requirements of designers, constructors and managers in the building and construction industry.
- Common injuries and accidents on building and construction sites and how they can be prevented.
Building operations and works of engineering construction (safety and health) specific rules {Section 55 (2) and 60 of the Factories Act, subject to the provisions of sub section (a) of section 5, of the Factories Act provides for a health and safe environment at construction sites. It outlines the need for an organization’s commitment to have the safety and health of its employees at work, above all the broad responsibilities of both the management and the work force.
The subsidiary legislation that applies to the construction industry is the Building operations and works of engineering construction safety and health special rules statutory instrument 198-17 which includes that:” Before any building operations or works of engineering construction begin, the undertaker of works must serve the commissioner of occupational safety and health a written notice of the intentions to carry out works at the site in question within 30 days or in good time before so doing, as per section 8 of the Factories Act."
All concerned parties are beginning to be alert and vigilant about promotion of site safety and in line with this, the Uganda Police on 30 October 2004 impounded 150 bags of suspected fake cement on the market as the use of substandard building materials is partly responsible for site accidents and is thought to be a major contributor to the recent collapse of several buildings under construction in and around Kampala.
The Uganda National Bureau of Standards (UNBS)- an authority which standardizes materials in Uganda, on 19 November 2004 acknowledged that the impounded cement is substandard and that it doesn't conform to the standard [US310-1: 2001). That it exhibited unacceptable 2-day compressive strength of value 8.5 MPa against a standard of 10 MPa and thus should subsequently be handed over to UNBS and destroyed.
2.3 ACCIDENT
Accident as a hazardous event is undesirable and occurs unexpected. It is an unplanned occurrence that happens after a sequence of events, the results may lead to:
- Physical harm (injury or death),
- Damage to property,
- Time loss,
- Loss of production,
- Fear and loss of morale among workers.
- Loss of money and other resources,

2.3.1 Causes of Accidents
Accidents do not just happen, they are caused and the causation is a complex issue, hence a lot has to be looked upon on how they happen and how to prevent them. Causation of Accidents may be categorized into three areas, namely
- Human Factor
- Technical factor
- Working Environment factor
illustration not visible in this excerpt
Photo.2 Inadequate scaffolding during a building modification on Nakivubo Street.
From photo 2 above, it is clear that work is being done in unsafe working environment in following ways:
- The scaffolding is inadequate as there is no enough transoms, no guard rails to stop anyone from falling and enough boards to give a safe working platform.
- Ladders are being used for tasks supposed to perform by scaffolding.
- There are no nets to stop both falling objects and workers in case of a falling situation.
- No personal protective wear to minimize the severity of accident in case it occurs.
2.4 FACTORS WHICH INFLUENCE ACCIDENT CAUSATION.
2.4.1 Human factor
The human factor is due to human behavior and attitudes towards safety when at work. The human error and state in which the workers are in may cause an accident. For example accident(s) may occur because the worker(s) is/ are:
- Drunk,
- Tiredness,
- General Laxity behavior about safety,
- Unaware of the presence of such a risk that may lead to an accident,
- Human impairment like poor eye-sight of worker,
- General human error as a person.
2.4.2 Technical factor
The technical factor takes on the technical aspects, which could lead to accident, and these include;
- Bad building designs- those that are prone to accident at construction and maintenance level,
- Inadequate designs of structural elements of the building like columns that can not carry the intended loads etc,
- Poor quality building materials like low quality cement, reinforcement, poor mix ratios etc,
- Misinterpretations of working plan and detail drawings,
- Bad construction methods and practices,
- Incompetent worker-force for implementation of project,
2.4.3 Working Environment factor
Working Environment factor takes on those factors that induce or influence accident causation because of the working situation the workers are exposed to and general condition the surroundings.
It’s important to appreciate that workers are sometimes faced with situations and conditions that are dictated by nature, state of operation and other external influencers. Working environment factors include;
- Working in poor weather,
- Working without personal protective wear,
- Working generally in unsafe environment like emergence repair works on a powerhouse that feeds a theatre of a major hospital, etc.

Photo.3 Poor and unstable scaffoldings without guardrails at a building in old Kampala.
From photo 3 above, it is seen that the scaffolding is poor and unstable in the following ways.
Its does not have the some of standard elemental components like; guard rails, stop nets, strong standards, on work platform, no well secured transoms. Hence it can be dangerous and cause an accident by collapsing when in use.
2.5 ACCIDENT MANAGEMENT STRATEGY
2.5.1 Accident Information System
National Accident Information System should be established which help to provide reliable information for accident monitoring and prevention, it serves:
- To provide accident statistics,
- To give a reliable and valid picture of occupational injuries,
- May be used in establishing the interrelationships between injuries and other economic, social indicators and hidden interactions can be revealed in the societal developments,
- To help safety organizations to monitor safety development and provide interventions in the right areas.
