FINDINGS OF GROUP 1
General
Before a decision is taken on the choice of hauling equipment,
a careful analysis should be carried out on the alternative means
of transport which may be appropriate (i.e., animal drawn carts,
tractors and trailers, trucks). Only when a proper cost analysis
has proved the viability of the tractor-trailer alternative, should
the following recommendations be considered.
Tractor-trailer Combination
Various labour-based programmes have run trails using different
design and sizes of trailers and tractors. Experience has shown
that basic, unsophisticated and solid designs provide the most reliable
services, reducing the amount of mechanical maintenance and ensuring
a high rate of plant availability.
The work group tried to find recommendations for the design and
specifications for a tractor and trailer suitable for gravel haulage
for labour-based road works. This trailer should be considered for
new projects which as yet do not possess any equipment.
The findings of Group 1 can be summarized as described in the table
on the following page.
Trailers
The trailer loading capacity should be limited to 3 cubic metres.
The chassis should be carried by an A-frame and a single axle.
In order to increase the traction capability of the tractor, at
least one third of the trailer weight and load should be transferred
to the rear axle of the tractor. The choice of tyres should correspond
to the most common truck tyre available in the country.
Side doors for unloading are not recommended. Experience from Kenya
shows that this item often breaks and requires a great deal of maintenance.
Secondly, it has been proven through time studies that the increased
unloading time is marginal. When also considering the increased
availability rates of trailers without side doors, it is clear that
this is the most feasible alternative.
Variations
In order to reduce the unloading time, one may experiment with
the use of front side doors. However, it is recommended that the
increased efficiency due to using side doors should be closely monitored
and documented before it is introduced as a standard item.
A second variation may be the introduction of removable tail gates
in order to increase the carrying capacity of the trailer as well
as reducing spilling.
It is not recommended that new programmes introduce or initiate
trails on tipping trailers. Ongoing test trails with non-hydraulic
tipping trailers in Kenya are promising. However, it should be emphasized
that they are still at the prototype stage. If the trails finally
show positive results, this experience will be disseminated to other
projects. New projects should wait with the introduction of tipping
trailers until the MRP has reached its conclusions.

Tractors
The appropriate tractor for hauling a 3 m3 trailer of
gravel is a 2 wheel drive with a 55 - 65 HP engine. 4 wheel tractors
are not necessary for this purpose. If the tractor is to be used
for other purposes (ploughing, towed grading, etc.), one may consider
more powerful models. One solution is to invest in a limited number
of more powerful multi-purpose tractors. The remaining fleet of
tractors with the above specifications would be entirely designed
for gravel haulage.
Trailers are repeatedly hitched and unhitched from the tractor.
The tractor should therefore be fitted with a heavy duty automatic
hitch which picks up and detaches the trailer automatically. The
pin and eye lock is the most common lock system and cheapest solution.
The ball and cup mechanism is more solid but also more expensive.
The rough environment on labour-based road sites and in the gravel
quarries requires that the tractor be fitted with heavy duty rims
and industrial tyres.
To ensure a regular and sufficient supply of spares, the chosen
tractor supplier should have a significant market share in the client
country.
If the equipment is to be used in mountainous or steep terrain,
it is advised that the tractor be fitted with roll-over bars. In
flat terrains this is not necessary. It is not very often that the
tractors capsize due to the trailer tipping over to the side. Usually
the hitch brakes before rolling the tractor over.
Further Action
The above specifications are similar to the trailer-tractor combination
recently developed by the Minor Road programme in Kenya. It is proposed
that these specifications be distributed by ASIST to the various
labour-based programmes in the region. One way of doing this, is
to publish the design and technical drawings in the next issue of
the ASIST journal.
The above findings should also be incorporated in a revised version
of the ILO Guide to Tools and Equipment for Labour-based Road Construction.
A final decision on this activity will be taken based on the review
and evaluation of the ASIST programme scheduled for January 1994.
Finally, the national executing agencies responsible for the road
programmes should insist on these standardized specifications when
equipment is supplied by the donors.
FINDINGS OF GROUP 2
Main Question
The main issue discussed in Group 2 was how to move labour-based
road construction and maintenance from the public sector to the
private sector involving domestic small-scale contractors as well
as consultants.
In order to achieve this transfer, there is a great demand for
training of Government staff, as well as the various levels of staff
in the local construction and consultancy firms. Therefore, the
group focussed on the desirability and type of training to be given
to contractors and consultants.
The topic was sub-divided into the following key questions:
| Is training for small scale contracting desirable?
Type of contractor development.
What material is available?
What new material is needed?
How do we integrate existing material?
How do we encourage womens involvement?
|
There was full agreement along the group members that a structured
training programme is a key element for the successful involvement
of the domestic private sector in labour-based road construction
and maintenance works.
Classification of Contractors
Before a training programme is formulated, it is important to define
the various types of contracting companies which can be found in
developing countries. The table below provides a general description
of the different types of contractors categorized according to their
size and the type of works they are able to carry out.
Petty Contractors
The petty contractor is generally referred to as the one-man contractor.
This category of contractors usually consists of one man firms,
sometimes assisted by a limited amount of unskilled workers. They
may be labour contractors, usually consisting of a businessman sub-contracted
to carry out specific work relying mainly on unskilled casual labour.
Organized local community groups such as farmers associations and
village welfare groups can also be classified as petty contractors.
Types of Contractors
| Type Description |
|
Petty Contractors
Single person
Labour only
Not registered
Basic skills
|
|
Small-scale Contractors
Registered
Possess basic equipment
Capital security low
Entrepreneurial skills
Technical and managerial skills
|
| Large-scale contractors - not interested |
A common feature for this group is that they are not formally registered
and do not possess any capital and are therefore extremely vulnerable
to cash-flow problems such as mobilization capital and late payments.
The petty contractors normally do not possess any equipment, and
lack any means of transport. Due to their lack of mobility, they
are normally recruited from the vicinity of the project work sites.
These contractors are mainly used for maintenance works or simple,
clearly defined sub-contracts requiring a minimum of skilled labour
and equipment. In Kenya, the lengthmen securing the routine maintenance
of the minor roads network are organized as one-man contractors.
In Lesotho, the Labour Construction Unit utilizes one-man contractors
for contracting out masonry works for small bridges and culverts.
Small-scale contractors
Most domestic small-scale contractors are found in the building
construction industry and the transport sector and are normally
registered companies. Often limited, they still possess certain
technical and managerial skills. However, experience shows that
their organization requires further training in business management,
accounting, mechanical maintenance, road and concrete technology,
as well as in labour-based methods.
Their equipment fleet is spares and often old and poorly standardized.
Before they can be used for road rehabilitation works, it is usually
necessary to assist them in the acquisition of additional light
construction equipment (i.e., hauling and compaction equipment).
Similar to the petty contractors, the small-scale contractors are
often underfinanced and vulnerable to cash-flow distortions. Normally,
these contractors do not operate their accounts through a bank.
In many cases the local banks do not consider these firms as attractive
clients and therefore do not provide them any service.
After receiving appropriate training development assistance, these
contractors have proven to be highly efficient in carrying out both
road construction and maintenance works. They have shown good supply
of work, regular and timely payments, etc.: they will survive as
sound construction firms and an important component of the domestic
construction industry.
Large-scale contractors are often subsidiaries of large
foreign multi-national companies in international competitive bidding
and are often only present in the country while they are carrying
out a contract. Once their assignment has been completed, they leave
the country, including evacuating equipment and skilled staff. Due
to this, their involvement provides a minimal technology transfer
to the recipient country, resulting in a low sustainability and
little institutionalization of skills and experience. In most cases,
they regard the size of labour-based road contracts as too small
for their interest. For these reasons, this category of contractors
is not regarded as part of the beneficiary target group for training
and development assistance.
Training Material
For the training and development of petty and small-scale contractors,
it was acknowledged that there already exists a certain amount of
training material produces by ongoing contractor development programmes
in the region (ghana, Madagascar, Lesotho and Tanzania). This training
material consists of (i) general literature on labour-based road
construction and maintenance technology developed by the ILO, and
(ii) specific material developed for contractor development and
management.
In addition, the ILO has produced a series of publications on domestic
contractor development and management for the construction industry
in general under its Improve Your Construction Business Programme
(IYCB). However, this material needs to be further developed and
specifically adapted to labour-based road works.
Required Training Material Yet to be Developed
Country Specific
When commencing on a new programme the above mentioned literature
needs to be adapted into country specific training material, taking
into consideration local conditions, technical standards and type
of works to be carried out.
In some instances, it would be useful to translate the material
into local language.
Finally, it should be adapted to the level of education among the
target group, in relation to the skills of the staff of the contractors,
as well as the government implementing agency, i.e., supervisors,
inspectors, mechanics, administrative staff, etc.
Training of Trainers
In order to ensure a sustainable programme, it is crucial that
the training capacity for this type of programme be fully institutionalized
in the country. To achieve this objective, there is a demand for
a structured training programme for trainers.

Selection of Contractors
Depending on the type of works to be carried out, there is a demand
for developing guidelines for the identification and selection of
contractors with the appropriate skill profiles.
Employment Conditions
In order to ensure smooth working relations between the workers
and employers, it is recommended that a standard set of guidelines
for employment conditions be developed.
Training of Local Consultants
When involving the private sector in the execution of labour-based
road works, it is important not to leave out the consultancy firms.
In the process of involving more and more parties in labour-based
programmes, this knowledge and experience should also be disseminated
to consultants. The preferred target group is local or indigenous
companies, well established in the country.
In order to transfer labour-based technology to consultants, there
is a demand for training. As a basis, materials already available
cover the various topics required. However, this material would
have to be adapted to meet the specific future role and tasks of
the consultants.
In South Africa, local consultants have been involved in the design,
implementation and monitoring of labour-based public works. For
this purpose, they have developed a set of interim guidelines for
the involvement of private consultants for this type of works, which
may be a good basis for the further development of similar guidelines
for other countries.
Womens Involvement
It was acknowledged that women should play an important role in
this programme and should be mobilised as contractors and consultants
as well as being properly represented among the work force of both
skilled and unskilled labour. In order to provide equal employment
opportunities to both men and women, it is essential that proper
guidance be provided on procedures and actions required to achieve
this objective.
Guidelines should be developed for selection and identification
of contractors/consultants describing specific measures which ensure
an active participation of women in the rural areas.
Further Action
Training programmes at national level should undertake the translation
of the training materials into national or local languages. Furthermore,
trainers should make better use of existing material as identified
by the group. The Technical Enquiry Services of ALIST can assist
in the distribution of the material.
Training of trainers for small-scale road contractors development
programmes is important. The ASIST Training of Trainers Course is
still under development and should cater for this recommendation.
Through the participation of two trainers for Ghana in the ALIST
Training of Trainers course in Kenya, ALIST has established a contact
with resource persons in the small-scale road contractor development
programme in Ghana. During their visit to Kenya, ALIST requested
them to design a purpose-made course for small-scale road contractors
based on their past experience in contractor training.
The registration and certification of the various types of contractors
is an important issue. Identifying the unregistered contractors
can often be difficult. If all contractors were registered, could
also lead to improved Government recognition and commitment to this
sector.
FINDINGS OF GROUP 3
Introduction
The main task of this group was to look at the organizational system
required when developing small-scale contractors to execute labour-based
road construction and maintenance works.
As a general remark, it was acknowledged that the type and size
of the programme and works to be carried out determine the type
of contractors required, as well as the need for consultants. Furthermore,
the availability, size and skills of the domestic contractors and
consultants influence the design of a programme. This type of project,
when involving the private sector, should be programmed on a long
term basis.
Role of Local Consultants
When road rehabilitation and regravelling works of a certain size
are awarded to labour-based contractors, local consultants can play
a useful role. For routine maintenance, petty contracts and direct
control by the road agency are more appropriate.
The main advantages of involving local consultants in the design
and implementation of labour-based orad programmes are:
The main advantages of involving local consultants in the design
and implementation of labour-based road programmes are:
Consultants represent an additional capacity (manpower, skills),
which can reduce the tasks of the respective Government organizations;
The consultants can act as a neutral body;
In order to protect their reputation, they will perform their duties
on time (i.e., prepare certificates leading to timely payment of
contractors).
Training
Before consultants can play a full role in labour-based road programmes,
there is a demand for training of the consultants in labour-based
technology, as well as establishing a capacity within the Government
technical line agencies to control both the contractors and the
consultants. This training programme will need to be developed in
line with the size of the programme and the consultancy input requirements.
Conclusions
In order to involve the private sector fully in labour-based road
works, the following activities were identified:
(i) Define tasks (terms of reference) for consultants in every
phase of a programme. Attache engineers from consultancy firms
to labour-based road programmes (typical consultant tasks might
include prioritization of roads and technical auditing).
(ii) Standardize methodology of project management, control
and documentation.
(iii) Clearly define roles of Government, client, consultants
and contractors.
(iv) Consultant involvement will imply selection, training,
special registration, conditions of involvement, etc.
(v) Large consultants could be used to train small consultants
if tasks are well-defined.
Relationship between large and small contractors
The group discussed the possibility of using large contractors
for training of small-scale contractors through sub-contracts.
Their motivation of the large contractors to carry out such a training
programme will depend on their terms of reference and the main objective
of the project. Is the main objective the construction works or
the development of private construction firms? In case of the latter,
the role of the large contractors is better defined, and he will
be judged on his training role performance. His motivation and interest
will also depend on his fear of future competition.
Training of small-scale contractors by large contractors could
be initiated in two different ways:
(i) Large contractor awarded contracts, but is forced to sub-contract
a certain percentage of the works to smaller firms.
(ii) Large contractors role is defined as training and development
of smaller firms only.
The second option means that project outputs should be defined
in terms of competent small contractors trained in management, accounting,
site management, etc.
In general, the workshop participants had limited positive experience
with on-the-job training by large contractors, and, in conclusion,
recommended that the Government hire individual contractor specialists
to work as consultants to train and guide small contractors.
