abstract={The purpose of this thesis work is to identify the warranty work and aftermarket work
that the case company faces. In recent years the case company has met an increase in
the warranty work. The master thesis has been carried out in a Swedish contractor and
is limited with remarks from warranty inspection protocols and data collection for
four apartment projects. The study is based on interviews with senior executives in the
case company.
The results in this study show that the three most common defects that occur during
the first two years are as follows: cracks on walls/ceilings, cabinet and boxes and
doors. This three building parts account for 55.5% of the total number of remarks,
based on the warranty inspection reports. The study presents appropriate improvement
work to avoid the emergence of the warranty work and to facilitate the follow-up of
the warranty work.
The main reasons for warranty remarks are based on several different conditions. The
causes can be attributed to moisture-related movements, lack of care and maintenance,
assembly errors and lack of product selection. The design phase has the major role
when it comes to rework. This in turn led to quality errors to occur. Furthermore, the
pressure of time in the construction sector has an impact in the result of quality
shortcomings. Construction companies are willing to be done in a shorter time than
they really need. This naturally leads to stress at the last stage and leading to shortages
at the end of the handover of the residence.
A closer relationship between the internal organization and the site manager is needed
to solve aftermarket problems in a more efficient way. Most of the experiences
learned from previous project are not delivered inside the organization, it rather stands
with the specific person. Therefore, it is important for the companies to gather
information and experience from previous project and deliver it to the project
organization. Companies should have strategies to encourage further training so that
individuals get better knowledge of the working methods. In order to prevent defects
and mistakes during the production phase, experienced personnel from the production
management should be involved in the early design phases.
