Magister Philosophiae - MPhil / In the early 1990s, South Africa (SA) entered its democratic transition, which created expectations of a dramatic turnaround in the country’s economy.1 The readmission of SA to the global arena introduced the economy to concepts such as globalisation. Globalisation came with some implications and impact that have been widely debated.2 The democratic transition brought a significant change to the job spectrum, generating an increase in Temporary Employment Service (TES) and a decrease in permanent employment.3 The reasons leading to this increase are that subcontracting is beneficial to employers in that this process results in the transferral of social risks to the subcontractor, reducing direct exposure to labour legislation.4 Regarding the pertinence of this issue, the Congress of South African Trade Unions (COSATU), the biggest union federation in the country, and the ruling party, the African National Congress (ANC), have long called for the elimination of labour brokers.5 COSATU, in its presentation to the Portfolio Committee on Labour in 2009, argued that labour brokers act as intermediaries to access jobs that allegedly exist, and which in many cases would have existed previously as permanent full time jobs.6 On the other hand, political organisations, such as the Democratic Alliance (DA), Congress of the People (COPE) and Business Unity South Africa (BUSA), have called for the regulation of labour brokers.7 These organisations argued that competition among businesses has increased over the past few decades. Therefore, in order to remain competitive, it is imperative to enhance technology and to adopt flexibility regarding human resource processes to minimise costs and to allow companies to broaden their investment based on the positive turnover that will occur. The continuing point of view of the opposition political coalitions has been to boost the corporate.

I byggbranschen arbetar man ofta i projekt där ett flertal olika parter samarbetar. Det är viktigt att samarbetet fungerar väl för att uppnå ett sådant positivt resultat som möjligt. Syftet med detta examensarbete är att studera hur samarbetet fungerar, kan förbättras och utvecklas mellan beställare, huvudentreprenör och underentreprenör på ett byggföretag. För att kunna utveckla det gemensamma arbetet är det viktigt att undersöka de vanligaste problemen och bristerna som kan uppstå. Genomförandet har skett genom intervjuer med utvalda parter i de projekten som studerats för att få en så klar och rättvis bild som möjligt av hur det fungerar, samt var styrkorna och svagheterna ligger. Tre projekt med stor variation har studerats i detta arbete för att kunna lokalisera och verifiera de vanligast förekommande problemen då man arbetar tillsammans. Några av de viktigaste aspekterna för ett positivt samarbete är att ha en god kommunikation, en genomtänkt planering inför projektstarten och en välgjord tidplan. Det är även mycket viktigt att samtliga parter vet innebörden av sin roll och håller sig till sitt ansvarsområde. Det är viktigt att Byggtech vårdar om sitt förtroende de har byggt upp hos sina beställare då deras affärsidé är beroende av fasta samarbeten med avtalade uppdragsgivare. Slutsatser som kan dras i detta examensarbete är att tydlighet, gemensamma riktlinjer och en god kommunikation är viktigt för att samarbetet mellan alla parter ska kunna utvecklas i positiv riktning. / In the construction branch you often work with projects where multiple parties cooperate. It’s important that the collaboration between the parties works well to achieve a positive result. Our aim with this thesis is to study how cooperation works, can be improved and developed between client, contractors and subcontractors on a construction company. In order to develop the joint work, you have to examine the common problems and deficiencies that may arise.   The implementation has been done through interviews with selected partners in the projects studied in order to obtain as complete and accurate as possible of what works and where the strengths and weaknesses are. The projects with wide variation have been studied in this thesis in order to locate and verify the most common problems when collaborating.   Some of the most important aspects of positive cooperation is to have a good communication, smart planning before the project begin and a well-managed schedule. It’s also very important that all the parties know the meaning of their role and stick to their responsibility. It’s fundamental that Byggtech cares for the trust they have build with their clients as their business depends on a solid partnership with the contracted clients.   The conclusions that have been drawn from this thesis are that clarity, common guidelines and a good communication are important to have a good collaboration between all the parties in order to develop the collaboration in a positive course.

The present article develops the legal concept of subcontracting on the frame of public procurement, according to the new Peruvian Public Procurement Law.Thus, different topics are treated: the differences between the outsourcing contract, derivative contract and subcontract; the new parameters that regulate subcontract; relevant aspects to consider for subcontracting on the frame of the new Public Procurement Law; and the lack of responsibility on the subcontractor towards the administrative entity. / El presente artículo desarrolla la figura jurídica de la subcontratación en los procesos de contratación pública, según la nueva Ley de Contrataciones con el Estado – Ley N° 30225. Así, se desarrollan temas como: las diferencias entre contrato de aprovisionamiento, contrato derivado y subcontrato; los nuevos parámetros bajo los cuales se circunscribe la figura de la subcontratación; aspectos que deben considerarse para la aplicación de la figura de subcontrato bajo la Ley Nº 30225; y, la falta de responsabilidad del subcontratista frentea la Entidad por la prestación brindada.

This thesis describes a research investigation into the implementation of the Last Planner System (LPS) in Nigeria, to improve construction processes within the Nigerian construction industry. LPS is known to be the most developed practical use of Lean Construction. It focuses on minimising the negative impacts of variability, uncertainties, buffers, making projects more predictable, creating reliable work plans and convalescing collaborative planning. However, the Nigerian construction industry is associated with a number of challenges which impair its performance. These challenges were grouped and classified into six major barriers: these include: supervision and quality control, fluctuation and variations, subcontractor involvement, resistance to change, cultural issues, and lengthy approvals. Consequently, a Design Science Research (DSR) approach is adopted to evaluate the effectiveness of implementing LPS in construction projects in Nigeria. In order to achieve this aim, an Action Research strategy is adopted and three case studies are reported; two of these cases describe how LPS was successfully implemented in construction projects within Nigeria. While the third case involved an investigation into the state of production plan reliability, of a successful project in Nigeria. These projects were selected based on non-probabilistic sampling from different geographical locations in Nigeria to represent different kinds of construction projects within the country. The first and second cases involved the implementation of LPS within the construction of a prototype student’s hostel and the construction a 4 Kilometre single carriageway road respectively. The third on the other hand involved the construction of a multipurpose hydro-power dam project; where comparisons were made between typical LPS projects and the project management techniques applied within the project. Data was collected through observation site activities, interviews, documentary analysis and questionnaire survey. The data generated was subsequently analysed by means of content analysis and evaluated in terms of its reliability, validity, representativeness, flexibility, rigour and reflexivity. In view of the LPS implementation within the two case studies, six barriers were identified and classified together with the six barriers associated with the Nigerian Construction industry. These barriers were linked, measured and ranked in averages of their degrees of occurrences. It was revealed that the major barriers were cultural issues and resistance to change, while the others include; lengthy approval, subcontractor’s involvement, poor supervision and quality, fluctuations and variations. Hence, a framework was developed to mitigate these barriers, when implementing LPS in construction projects in Nigeria. The main steps of the framework include: the need to identify purpose; the need to identify stakeholders impact; the need to obtain Sponsorship; the need to build a cross functional team; the need to create measurement indices; the need for training on Lean techniques and LPS; and finally the need to create a right working climate. Furthermore a focus group between construction practitioners was organised to test and evaluate the framework developed. It was revealed from the focus group that the framework has the potential to facilitate the implementation process as proposed.

This master’s thesis solves the problem of subcontracting. It analyzes the company of IMOS Zlín s.r.o., it recommends requirements for development of subcontracting in the company based on critical analysis in real building contract, which the company realized in the past.

This dissertation focuses on the management of a construction project from both a theoretical and practical perspective. The theoretical part deals with project management and specifficaly a contractor’s preparation ahead of the construction project, namely producing the tender and pre-production considerations. The practical part covers an analysis of contract’s management of a concrete project.

I denna studie utreds definitionen av samverkan, vad det egentligen innebär och hur detupphandlas, samt vilka för- och nackdelar som finns med samarbetsformen. Äveninvolveringen av strategiskt viktiga underentreprenörernas har studerats. För att undersökadetta har både en litteraturstudie och en kvalitativ intervjustudie utförts.Studiens utgångspunkt är upplevelsen och erfarenheten av att arbeta med samverkan och föratt få ett så brett perspektiv som möjligt intervjuades beställare, huvudentreprenör ochunderentreprenör.Litteraturstudien ger en överblick av byggbranschens problem som bland annat innefattarbristfällig projektering, otillräcklig kompetens och tidsbrist. I denna rapport beskrivs hursamverkansentreprenad växt fram som en motreaktion till dessa problem. Det redogörs ävenför vad som kännetecknar en lyckad samverkan och när det är som mest lämpat att använda.Resultatet visar att definitionen av samverkan är projektspecifikt och det är beställarensengagemang som är avgörande för att samverkan faktiskt genomsyrar projektet. Vidare visarstudien att upphandlingen till stor del sker på mjuka parametrar och att lagen om offentligupphandling, LOU, inte egentligen är något hinder.Sammanfattningsvis är det av stor vikt att en samverkansentreprenad består av gemensammamål, förtroende och transparens för att lyckas. / In this study, the definition of partnering is looked into, what it actually means and how it isprocured, as well as the advantages and disadvantages of partnering. The involvement ofstrategically important subcontractors has also been studied. To examine this, both a literaturereview and a qualitative interview study have been conducted.The starting point of this study is the experience of working with partnering, and to gain asbroad a perspective as possible, clients, main contractor, and subcontractor were interviewed.The literature study gives an overview of the construction industry's problems, includinginadequate planning, insufficient competence, and time constraints. This report describes howpartnering has emerged as a reaction to these problems. It also explains the characteristics ofsuccessful partnering and when it is most suited.The results show that the definition of partnering is project-specific, and it is the involvementof the client that is crucial for partnering to permeate the project. Furthermore, the studyshows that procurement largely relies on soft parameters and that the Public Procurement Actis not actually an obstacle.In summary, it is crucial for partnering to consist of shared goals, trust, and transparency inorder to succeed.

Det finns stora förbättringsmöjligheter inom logistiken i byggbranschen då den idag är väldigt kostsam och innebär många störningar i produktionen. Den logistik som sköts av underentreprenörerna i ett byggprojekt är ofta ej synkroniserad med huvudentreprenörens logistik vilket innebär ytterligare svårigheter. Dålig kommunikationen mellan aktörerna och en relation som karaktäriseras av misstro försvårar en mer integrerad logistik. Denna studie syftar därmed till att undersöka en alternativ lösning där huvudentreprenören övertar underentreprenörens materialansvar. En sådan lösning innebär att huvudentreprenören är ansvarig för all logistik och att underentreprenören utför monteringen. Genom intervjuer med en huvudentreprenör samt flera underentreprenörer och leverantörer har denna studie försökt besvara både hur bygglogistiken och relationen mellan huvudentreprenör och underentreprenör påverkas. I och med ett övertagande av materialansvaret får huvudentreprenören ökad kontroll över logistiken vilket innebär ett större ansvar men även möjligheter att förbättra leveranssäkerheten och att huvudtidplanen följs. Då de hanterar all logistik kan de i högre grad nyttja resurser som t.ex. samlastning via mellanlager och en intern tredjepartlogistiker. Huvudentreprenören kan även ha en tidigare och tydligare kommunikation med leverantören. Underentreprenören får ett minskat ansvar i och med övertagandet och även en minskad kontroll över logistiken vilket leder till att de blir mer beroende av huvudentreprenören. Detta innebär ett ökat samarbete mellan aktörerna och därmed krävs en förbättrad kommunikation. Ett övertagande innebär vidare att huvudentreprenören blir mindre beroende av underentreprenören vilket ökar risken för att underentreprenören ersätts. Den främsta fördelen med ett förändrat materialansvar är enligt studien att byggplatslogistiken förbättras. Svårigheter i övertagandet ligger dels i kulturella normer då det innebär en förändring av underentreprenörens roll i bygglogistiken men även i huvudentreprenörens brist på kunskap om underentreprenörens material. Vidare visar studien att det finns en oro bland aktörerna kring vem som är ansvarig vid problem med materialet och att omorganiseringen kräver en utredningsprocess som avgör om byggnationsfel orsakats av materialfel eller monteringsfel. Sammanfattningsvis visar studien att det finns en stor potential i att huvudentreprenören övertar underentreprenörens materialansvar men för att en sådan omorganisering ska bli lyckad så bör underentreprenören vara involverad i utformandet. Vidare krävs en tydlig ansvarsfördelning, en förbättrad kommunikation och en förståelse för andra aktörers perspektiv. Lyckas aktörerna med detta kan omorganiseringen innebära en effektivare produktion. / In the area of building logistics there are great possibilities for improvement since it is today very costly and entails many disruptions in the production. The logistics handled by the subcontractors are often not synchronized with the logistics of the main contractor which leads to more difficulties. Bad communication between the actors and a relationship characterized by mistrust hinders more integrated logistics. The purpose of this study is to examine an alternative solution where the material responsibility is changed from the subcontractor to the main contractor. Such a solution entails that the main contractor is responsible for all the logistics and that the subcontractor will perform the assembly. Through interviews with a main contractor and several subcontractors and suppliers this study aims to answer both how the building logistics and the relationship between main contractor and subcontractor will be affected. As an effect of the change of material responsibility the main contractor will get a higher level of control over the logistics which results in a bigger responsibility but also the possibility to improve deliverance certainty and that the main time schedule is followed. As a consequence of them handling all the logistics they can to a greater extent utilize resources such as joint loading via storage facilities or an internal third-party logistics provider. The main contractor can have an earlier and more direct communication with the supplier. The subcontractor will have less responsibility as a result of the change but also a lowered control over the logistics which leads to a stronger dependence on the main contractor. This implies an increased cooperation between the actors and thus a demand for an improved communication. The main contractor will become less dependent on the subcontractor and therefore the risk for the subcontractor to be replaced will increase. The main benefit with the change of material responsibility is according to the study that the on-site logistics will improve. Difficulties with the reorganization are partly in cultural norms as it will change the subcontractor’s role in the construction logistics and partly in the main contractor’s lack of knowledge about the subcontractor’s material. The study also shows that there is a worry among the actors about who is responsible when a material problem occurs and the change demands an investigation process to determine whether a construction error is caused by a material or assembly error.  To conclude; this study shows a big potential in the material responsibility changing from the subcontractor to the main contractor but for such a reorganization to be successful the subcontractor should be included in the process of developing the reorganization. Furthermore, this demand a clear division of responsibilities, an improved communication and an understanding for the other actors’ perspective. If the actors succeed with this change of material responsibility it can lead to a more effective production.
