Thesis (MComm)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: This study explore how forecasting techniques can be combined in linear programming (LP) as a tool to optimise the parameters of forecasting methods in order to ensure sufficient capacity of logistic infrastructure exist for future growth. This study will use greenfield and brownfield projects from Sasol, a petrochemical company from South Africa, to test the methodology on. The methodology followed in the study was to firstly look at previous literature studies on logistical infrastructure and how to create sufficient capacity. Secondly, understandings of supply chain planning principles in general as well as supply chain planning in context of Sasol were investigated. Thirdly, different forecasting methods like; qualitative include judgemental, life cycle, Delphi method, market research etc. and quantitative methods including time series and causal methodologies had been investigated. Fourthly, decision making tools to incorporate multiple forecasts were investigated to understand why Sasol decided to use i2. Fifthly, the current capital project approach in Sasol had been investigated to fully understand where room for improvements would be possible. Finally the theory from the study was applied on two different projects in Sasol, one greenfield and one brownfield project. The results found that by using sound supply chain planning methodologies, sound supply chain design principles and multiple forecasts being combined by using LP decision making tools a better decision can be made with regards to logistical infrastructure investment as well as ensuring sufficient logistical infrastructure capacity. The two case studies have shown that this approach is flexible enough, apart from a few minor changes and can be adopted for both scenarios and that great results can be achieved. Logistical infrastructure could be optimised due to collaboration and the overall costs and performance of a supply chain improved. / AFRIKAANSE OPSOMMING: Hierdie studie ondersoek hoe lineêre programmering ( LP ), as n hulpmiddel, gebruik kan word om vooruitskattingstegnieke te kombineer om sodoende die vooruitskattingsmetodes te optimaliseer en te verseker dat voldoende kapasiteit van logistieke infrastruktuur bestaan vir toekomstige groei. Hierdie studie se metodes sal getoets word op groenveld- en bruinveldprojekte van Sasol , 'n petrochemiese maatskappy van Suid –Afrika. Die metode gevolg tydens die studie, was eerstens om te kyk na vorige literatuurstudies oor logistieke infrastruktuur en hoe om voldoende kapasiteit te skep. Tweedens, om ‘n breë oorsig van die beginsels van voorsieningsketting-beplanning te bekom sowel as voorsieningsketting-beplanning in die konteks van Sasol te ondersoek. Derdens, verskillende vootuitskattingsmetodes soos kwalitatiewe metodes (insluitend veroordelende-, lewensiklus- en Delphi-metode en marknavorsing) en kwantitatiewe metodes (insluitend die tydreeks- en oorsaaklike metodes) is geondersoek. In die vierde plek is besluitnemingshulpmiddels, wat verskeie vooruitskattings kombineer, geondersoek om te verstaan waarom Sasol besluit het om i2 aan te koop. In die vyfde plek is die metode van Sasol se kapitaalprojekte geondersoek om te verstaan of daar nie moontlik ruimte vir verbeterings sou wees nie. Laastens is die studie se metode op twee projekte van Sasol toegepas, een groenveld- en een bruinveldprojek. In die studie is gevind dat beter besluite geneem kan word aangaande beleggings in logistieke infrastruktuur en om te verskere daar is voldoende logistieke infrastruktuur kapasiteit - deur gebruik te maak van optimale metodes in voorsieningsketting-beplanning en voorsieningskettingontwerp. Die twee gevallestudies het getoon dat hierdie benadering buigsaam genoeg is, afgesien van 'n paar klein veranderinge, om vir beide moontlikhede gebruik te kan word en goeie resultate te behaal. Deur die samewerking van verskeie besigheidseenhede kon logistieke infrastruktuur geoptimaliseer word terwyl die kostes en algehele prestasie van voorsieningsketting verbeter kon word.

Thesis (MDevF (Business Management))--University of Stellenbosch, 2007. / ENGLISH ABSTRACT: This study looks at South Africa and Brazil in a comparative sense to determine how infrastructure development and investment since 1970 to 2002 impacted not only on aggregate GDP but also on social indicators such as gross national income (GNI), infant mortality and literacy within these countries. Although Brazil is four times the size of South Africa, the two countries have political and economic situations that are similar. The more recent history of the two countries suggests that infrastructure development and investment have received priority. The research methodology was to review related literature, secondly to statistically measure the impact of infrastructure investment on the factors mentioned using a linear regression model and, thirdly to analyze and discuss the outcomes. The role of government in infrastructure development is argued to be one of limited capital investment and more of a regulatory one with the consequent result of crowding-in private sector investment. Brazil has in recent times followed a route of public-private partnerships with the South African government on the other hand being the principal investor for infrastructure. The magnitude of elasticity of the impact of infrastructure in both South Africa and Brazil was found to be unusually large implying an implausibly high marginal rate of productivity for capital investment. This could be because of the incompleteness of the data obtained. Furthermore, infrastructure investment in Brazil is found to have a larger social impact than in South Africa, except for aggregate GDP. In conclusion, the results of the statistical analysis corroborate the assertion of the various literatures surveyed. The main findings of the analysis in this study do not conclusively suggest that the path followed by Brazil through public-private partnerships has had a far better effect than in the case of South Africa utilizing substantial government investment to promote infrastructure development. Although the study was not geared towards the effect of policies on the impact of infrastructure, especially on the social fabric of developing countries, further research in this area could be undertaken. The impact of individual measures of economic infrastructure such as railways, roads, ports, air travel, telephones and electricity could also be researched to determine their economic impact in South Africa and Brazil. / AFRIKAANSE OPSOMMING: Hierdie studie tref ‘n vergelyking tussen Suid-Afrika en Brasilië om vas te stel hoe die ontwikkeling van infrastruktuur en belegging sedert 1970 tot 2002 nie net op die totale bruto binnelandse produk, maar ook op die sosiale aanwysers soos die bruto nasionale inkomste, die sterftesyfers van babas en die geletterdheidsvlakke van die lande impak. Alhoewel Brasilië vier maal groter as Suid-Afrika is, het die twee lande soortgelyke politieke en ekonomiese situasies. Die meer onlangse geskiedenis van die twee lande toon ook dat infrastruktuur en belegging geprioritiseer is. Die navorsingsmetodologie wat gebruik is, is om eerstens die betrokke literatuur te hersien, tweedens om statisties die impak van infrastruktuurbelegging op die gemelde faktore te meet deur ‘n lineêre regressiemodel te gebruik en derdens om die uitkomste te analiseer en te bespreek. Die rol van die regering in infrastruktuurontwikkeling word beskou as een van beperkte kapitaalbelegging en ‘n meer regulerende een met die gevolglike resultaat van verdringing van privaatsektorbelegging. Brasilië het onlangs die weg van openbaarprivate vennootskappe begin volg terwyl die Suid-Afrikaanse regering andersyds die hoofbelegger in infrastruktuur is. Dit is bevind dat die omvang van die elastisiteit van die impak van die infrastruktuur op beide Suid-Afrika en Brasilië ongewoon groot was, wat impliseer dat daar ‘n ongewoon-hoë marginale produktiwiteitskoers vir kapitaalbelegging was. Dit kan as gevolg van die onvolledigheid van die data wees. Verder het infrastruktuurbelegging in Brasilië ‘n groter sosiale impak as in Suid-Afrika getoon, buiten vir die totale bruto binnelandse produk. Ten slotte bevestig die resultate van die statistiese analise die aannames van die verskeidenheid literatuur wat geraadpleeg is. Die hoofbevindings van die analise in hierdie studie bewys nie dat die weg wat deur Brasilië deur middel van openbaar-private vennootskappe gevolg is ‘n baie beter effek het as wat in Suid-Afrika tot stand gebring is deur die benutting van die omvattende regeringsbelegging om infrastruktuurontwikkeling te bevorder nie. Alhoewel die studie nie gefokus was op die uitwerking van die beleide op die impak van infrastruktuur nie, veral op die sosiale sy van ontwikkelende lande nie, behoort verdere studie op hierdie gebied onderneem te word. Die impak van individuele maatstawwe van ekonomiese infrastruktuur soos spoorweë, paaie, hawens, lugvaart, telefone en elektrisiteit kan ook nagevors word om die ekonomiese impak op Suid-Afrika en Brasilië te bepaal.

Thesis (MDF)--Stellenbosch University, 2014. / The aim of the study is to provide a framework for effective private sector participation in infrastructure development and finance, not to provide a rigid structure to guide the participation. Thus the framework is a flexible guide to guide the relationship with local governments. The study will be limited to the following aspects: - projects commissioned and managed by the local sphere of government in South Africa; - projects financed by funding outside of the national treasury budget allocations; and - infrastructure projects that may include physical infrastructure (roads), social infrastructure (clinic) and economic infrastructure (electrical substation). Even though the scope of the study may be limited, the study can provide critical insight in terms of private sector participation possibilities in infrastructure development in South Africa.

Thesis (MScEng)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: South Africa is currently experiencing a time in which existing infrastructure is reaching its design life end. With a growing economy and the increased level of social development, existing infrastructure is under extreme pressure. South Africa is also facing a challenge in which a need exists for engineering capabilities. These capabilities include engineering skills to maintain and manage existing infrastructure, plan for new infrastructure and construct new needed infrastructure. This study looks at a possible solution towards the above mentioned challenges. As a solution, the study proposes a professional development program to prepare engineers to work in the environment of infrastructure development. More specifically the program prepares civil engineers to work in public sector organisations responsible for basic service infrastructure. The research for the proposed professional development program is done by comparing literature with feedback received from various industry professionals. By doing this, the components for the proposed program were researched and identified. The components for the proposed program are professional work experience, professional training and structured mentorship. A further deliverable of the proposed program is to assist candidates taking part in the program to register as professional engineers on completion of the program. The study further showed the proposed program should be structured in such a way that all the components mentioned above work together interactively and should be centrally managed to ensure all the goals for the program are being reached. It is further stated that if the proposed program could successfully be implemented and if all the stakeholders commit towards the goal of the proposed program, the program could have a significant positive impact towards the challenges mentioned above. / AFRIKAANSE OPSOMMING: Suid-Afrika beleef tans 'n tyd waarin bestaande infrastruktuur besig is om hul ontwerp tydperk te bereik. Met 'n groeiende ekonomie en die verhoogde vlak van maatskaplike ontwikkeling is bestaande infrastruktuur onder geweldige druk. Suid- Afrika staar ook tans `n uitdaging in die gesig in verband met onvoldoende getalle professionele ingenieurs, veral in die omgewing van die instandhouding van bestaande infrastruktuur, die konstruksie van nuwe infrastruktuur, en die beplanning van verdere nodige infrastruktuur. Hierdie studie ondersoek dus 'n moontlike oplossing tot bogenoemde uitdagings. As 'n moonlike oplossing stel die studie voor dat `n professionele ontwikkelingsprogram vir ingenieurs saamgestel word. So `n program sal dus ingenieurs oplei en voorberei vir werk binne die openbare sektor wat verantwoordelik is vir die ontwikkeling en bestuur van basiese dienste infrastruktuur. Die navorsing vir die voorgestelde professionele ontwikkeling program is gedoen deur bestaande literatuur te vergelyk met inligting ontvang vanaf verskeie professionele ingenieurs in die praktyk. Deur dit te doen, is die komponente vir die voorgestelde program nagevors en geïdentifiseer. Die geïdentifiseerde komponente vir die voorgestelde program is dus soos volg: professionele werkservaring, opleiding en gestruktureerde mentorskap. 'n Verdere aflewering van die voorgestelde program is om kandidate te registreer as professionele ingenieurs teen voltooiing van die program. Die studie toon ook verder aan dat al die komponente, soos wat hierbo genoem is, geïntegreerd moet plaasvind en dat die program gestruktureerd bestuur moet word vanaf `n sentrale punt of organisasie. Dit word dan verder genoem dat indien die voorgestelde program suksesvol geïmplementeer kan word, en indien die verskeie belanghebbendes tot die program hulle self tot die program kan verbind, die program 'n beduidende positiewe impak op die uitdagings hierbo kan maak.

The year 1994 marked the dawn of the new democratic South Africa, bringing its own set of challenges to the country. Currently urban areas cover only one and a half percent of South Africa’s surface area. However, sixty one percent of South Africans live in urban areas. Furthermore, the average growth rate for urban areas has been consistently higher than the population growth rate during the period from 1998 to 2008. This resulted in larger towns and cities, growing at the expense of rural areas, with metropolitan areas experiencing the highest influx, followed by secondary cities. However, urban areas consume more water, food, energy, and durable goods, and have an impact far beyond the urban boundaries. This directly relates to urban decline. The rapid influx of people into urban areas that are already overcrowded with large service delivery backlogs, has led to the formation of informal settlements in exposed locations. Many of the informal dwellings in South Africa are subjected to environmental factors. The absence of basic services in overcrowded areas is linked to negative health outcomes and enhanced environmental degradation. This study is a critical review of a phenomenon named urban resilience. The report seeks to highlight the current status in cities and the transformation that cities need to undergo to enable them to become the cities of tomorrow. Indeed, “sustainable future cities and human settlements begin today”. The paper raises arguments on urban resilience by different theorists, philosophers, academics and scholars. The study proceeds to unpack the urban resilience determinants. Furthermore, the challenges cites will experience in responding to rapid urbanisation and their denial attitude to informal settlement and environmental degradation, which include how cities respond to climate change, are under investigation . The purpose of the study is to share the theoretical framework relative to the urban resilience determinants, with the intention to solicit criticism on gaps and blind spots. This is done with specific reference to Buffalo City Municipality. This study aims to contribute to the goals of municipalities by improving understanding of the drivers of urban resilience. This will, in turn, enable a city system to withstand and recover quickly from multiple and diverse shocks and stresses, and improve its performance over time. However, this study was conducted within a qualitative paradigm. The study followed a non-probability sampling technique. Categories of data sources were identified based on their probability to hold information that is crucial to the study. For each category, this study followed a 50 + 1 rule for sampling size when the population of the data sources were identified and access gained. he statistical software (SPSS) supported by a qualified statistician was used to analyse data qualitatively in attempt to answer the research question.

International students have become major role players in international education across the globe. Their enrollment in different universities has increased in the past few decades worldwide. Most of these students bring rich cultural diversity and skills to their various host institutions and countries. These trends signal the need to examine and understand international students within the South African context. Against this background, this study explores the factors that influence academic choices of international students, academic and social challenges they face and the role of social capital in influencing international student integration at the Universities of Fort Hare and Rhodes in South Africa. A qualitative research design was employed in this study. Thirty international students were selected (and interviewed) using purposive sampling and snowballing. The study found that some of the main factors that influence the academic choices of international students include availability of scholarships and funding, recommendations of the institution by family and friends, availability of preferred course and the reputation of the institution. Some of the main challenges faced by international students in these two institutions include language barriers, financial difficulty, expensive but improperly maintained accommodation and culture shock. These challenges impede the smooth integration of international students into their new academic and social environment. However, the students employ several strategies in attempt to address the challenges they face. These include joining a student or community social organization, community engagement and making friends. These social networks and organizations serve as a support system and connection hub for the students. The study recommends that it is pertinent for the University of Fort Hare and Rhodes University to meet the needs and expectations of its international students through regular surveys that give them room to speak about their experiences. The need for efficient International Offices at both institutions is crucial as well as the employment of open‐minded multicultural trained staff in these offices. The study also suggests the need for the both institutions to provide affordable and comfortable accommodation for its international students.

The study investigates the extent of distributional impacts of labour-intensive road projects using a geographical approach. The aim is to evaluate infrastructural effectiveness. The central premise is that the interface between road investment and economic development has broad implications that are beyond transportation’s basic purpose of providing access and mobility. Communities are motivated by the outcomes and impacts of road infrastructure development in improving the productiveness of the economy, in line with socio-economic development and other multiplying effects. The objective was to describe the nature and delivery mechanisms of labourintensive road projects, evaluate the impact thereof on the project participants and their communities and explore the constraints and challenges experienced by these initiatives. The impact of the Gundo Lashu programme was measured, based on an assessment of programme outputs, outcomes and impacts, to determine whether the project had the desired effects on individual participants and their households. A matched control case study design, using a combination of qualitative and quantitative approaches was adopted. The study found that the Gundo Lashu programme had achieved the expected outputs in terms of the total number of jobs created, total road length constructed and maintained. However, the communities’ socioeconomic outcomes and the impacts of the programme on poverty and sustainable livelihoods were mixed. These conclusions re-affirm the notion that the development of rural road infrastructure alone by labour-intensive construction methods, is not sufficient in tackling poverty. While government is focusing on addressing unemployment and skills development through labourintensive road construction programmes, there is a need to ensure proper integration of government services to make a significant impact. Huge deficiencies exist in the inter-linkages between the programme planning process and the municipal planning system and that there are a number of management and planning, structural and functional, human resources and funding barriers to proper planning, implementation and monitoring of projects within the Gundo Lashu programme. Various challenges and barriers emanates from lack of coordination, political interferences and lack of strategic direction. Key recommendations include comprehensive road planning, better project targeting mechanisms, development of guidelines for future maintenance, skills training and capacity development, and resultsbased monitoring. / Geography / D.

The annual budget cycle in urban road/transport authorities by implication requires transport infrastructure projects to be ranked in terms of their relative value, to enable project selection by starting from the most deserving proposal. This follows from the fact that the total cost of feasible projects practically always exceeds available funds, signalling the need for some kind of selection protocol. Cost benefit analysis (CBA), when applied in a narrow sense, is not suitable for this purpose as it focuses on economic efficiency only. Attempts to broaden it have been criticized by some scholars. Although the diversity of impacts points to a multi-criteria analysis (MCA) approach, this is considered unscientific in certain quarters; at best, its practical value needs to be demonstrated. In the case of the City of Tshwane (CoT), problems with current project appraisal are evident in that different methods – none of which is defensible – are used, sometimes resulting in rankings that are contradictory. This thesis therefore attempts the following: (a) to develop a basic approach that combines the best elements of traditional methods; (b) to customize this approach to the specific context and needs of road authorities in the municipal sphere of government, using CoT as an example; and (c) to demonstrate the application of the resulting appraisal framework, utilizing appropriate decision-support software for this purpose. Recommendations include the following: An appraisal framework should combine CBA and MCA by adopting an overall MCA approach with economic efficiency – focusing on the optimal allocation of scarce resources – as one of the decision criteria. For completeness‟ sake, three additional decision criteria are deemed necessary: equity (focusing on income distribution impacts); sustainability (focusing on environmental impacts); and compatibility (focusing on the alignment of projects with stated goals and objectives). This framework may well apply to road authorities in other spheres of government – the optimum application in each case will depend on the composition of the relevant decision-making team. The inherent nature of project appraisal requires a two-phased approach in all cases: the evaluation of mutually exclusive alternatives, followed by the ranking of independent projects. State-of-the-art decision support software is indispensable for implementing this framework. / Transport Economics / D. Com. (Transport Economics)

Thesis (MBA)--Stellenbosch University, 2000. / ENGLISH ABSTRACT: It is estimated that at present South Africa has a backlog in spending on infrastructure, amounting to R170 billion. The state does not have the necessary funds to rectify the situation. This problem is not unique to South Africa and across the world countries are considering whether private sector enterprises should not be rendering the services and constructing the infrastructure which the state had traditionally done. One of the most successful ways of doing this is to make use of public-private partnerships (PPP's). A PPP is a joint effort by the state and the private sector party to execute a major product, whereby the resources and abilities of the two parties are combined. The risks and responsibilities of the project are allocated to the parties in an optimal manner. The efficient and effective application of the PPP mechanism poses a challenge to the Western Cape Province as it is an excellent way to improve the utilisation of state property within the Province and construct new facilities. The Elsenburg vineyard and cellar project, a PPP project in the Western Cape Province, is therefore critically assessed in terms of key success factors in the implementation of PPP's. Furthermore recommendations regarding the future utilisation of PPP's within the Province are made. A dedicated PPP unit, which will be responsible for investigating the value for money, affordability, allocation of risks and recourse requirements of projects, should be formed within the Province. Members of the unit will also handle the management of PPP projects. It is important that officials who will be involved with PPP's are trained in the theory and practise thereof. Other important aspects are that all groups who have an interest in a PPP project be identified, that attempts are not made to transfer all risks to the private sector partner and that the standardisation of steps that are common to all projects be investigated. Property projects that are suitable for the application of PPP's must be identified as it can provide momentum to the economy of the Western Cape and can also contribute towards the erasing of the backlog in the construction and maintenance of infrastructure. / AFRIKAANSE OPSOMMING: Dit word beraam dat Suid-Afrika tans 'n agterstand in besteding op infrastruktuur het wat R170 biljoen beloop. Die staat beskik nie oor genoeg fondse om die probleem aan te spreek nie. Regerings die wêreld oor ondervind soortgelyke probleme en is besig om te besin of die oprigting van infrastruktuur en die lewering van dienste wat tradisioneel deur die staat hanteer is, nie eerder aan die privaatsektor oorgelaat moet word nie. Een van die suksesvolste maniere om dit te bewerkstellig is deur die gebruik van obenbare sektor-private sektor venootskappe (OPV's). 'n OPV is 'n gesamentlike poging deur die staat en 'n privaatsektorvennoot om 'n groot projek uit te voer, waardeur die hulpbronne, sterkpunte en vermoëns van die twee partye gekombineer word. Die risiko's en verantwoordelikhede wat aan die projek verbonde is, word op optimale wyse aan die partye tot die OPV toegedeel. Die doeltreffende en doelmatige aanwending van die OPV meganisme is 'n groot uitdaging vir die Wes-Kaapse Provinsie, aangesien dit 'n uitstekende manier is om benutting van staatseiendom binne die Provinsie te verbeter en nuwe fasiliteite op te rig. Die Elsenburg wingerd- en kelderprojek, 'n OPV-projek binne die Wes-Kaapse Provinsie, word derhalwe krities geëvalueer op grond van sleutelsuksesfaktore vir die implementering van OPV's. Verder word aanbevelings rakende die toekomstige aanwending van OPV's binne die Provinsie gemaak. 'n Spesialis OPV eenheid, wat verantwoordelik sal wees om die waarde vir geld, bekostigbaarheid, toedeling van risiko's en hulpbronbenodighede van projekte te ondersoek, moet binne die Provinsie gestig word. Die bestuur van OPV projekte sal ook deur lede van die eenheid hanteer word. Dit is belangrik dat amptenare wat by OPV's betrokke sal wees, opgelei word in die teorie en praktyk daarvan. Ander belangrike aspekte is dat alle groepe wat 'n belang by 'n OPV projek het, geïdentifiseer moet word, dat daar nie gepoog word om alle risiko's na die privaatsektorvennoot oor te dra nie en dat die standardisering van stappe wat gemeenskaplik is aan alle projekte ondersoek moet word. Eiendomsprojekte wat geskik is vir die aanwending van OPV's moet geïdentifiseer word, aangesien dit as inspuiting vir die Wes-Kaapse ekonomie kan dien en kan bydra tot die uitwissing van die agterstand in die oprigting en instandhouding van infrastruktuur.

Thesis (MDF (Development Finance))--University of Stellenbosch, 2009. / ENGLISH ABSTRACT: The traditional form of delivering infrastructure and services by government is fraught with problems. These include cost overruns, time overruns and neglect of maintenance resulting in dilapidated and aged infrastructure. Public-private partnerships (PPPs) are emerging as an alternative form of delivering infrastructure, not necessarily as a solution, but as a procurement option. PPPs have not been without problems either and one of them is deal flow. In this research deal flow is referred to as a rate at which PPP projects move in the pipeline from initiation to conclusion of the contract. Initiation means registration of the project by a sponsoring institution with the National Treasury of the Republic of South Africa and conclusion of the contract means financial close. Financial close is the last stage of the project when financial institutions are ready to disburse borrowed funds. It follows immediately after contractual close, i.e. the stage when parties to the agreement (government department and private sector) signed the contract. The main objective of the research was to identify factors that lead to a slow deal flow. As discussed in the research this movement takes place at a rate of two deals per annum in South Africa presently. This is not good if compared with countries such as the United Kingdom which closes deals at a pace of around 50 per annum. However it is recognised that South Africa is a developing country and is not at the same level of development as other European countries. This comparison is therefore done for benchmarking purposes. The other objective of the research was to find out where the occurrences of the blockages are in the project life cycle with the aim of removing or mitigating their impact. Finding answers to some of these questions will not only help the National Treasury but the whole country in delivering infrastructure. The motivation for this is that infrastructure development contributes to economic development, economic growth and poverty reduction and the creation of a better South Africa for us all. The main findings of the research are that a great amount of time is spent during the inception phase, that is from registration of the project to Treasury Approval 1 for the feasibility study. Contrary to literature which suggests that more time is always spent in negotiations, that does not seem to be a problem in South Africa. Therefore an aggressive push at inception phase is necessary. Lack of clear government objectives and commitment is a problem. Poorly defined sector policies and poor risk management are problems too. There is a lack of mechanisms to attract long-term finance at affordable rates. This research has proved that other phases in the cycle, i.e. Treasury Approvals 2A to Treasury Approval 3, are not a problem. In other words, the phase of inviting, evaluating, appointing and negotiating with bidders is not a problem and therefore a slow deal flow problem can be solved if initiatives are taken right from conceptualisation to feasibility. / AFRIKAANSE OPSOMMING: Die tradisionele manier waarop die regering infrastruktuur voorsien is deurspek van probleme. Dit sluit in oorspandering, oorskryding van spertye en gebrek aan onderhoud wat lei tot bouvallige en verouderde infrastruktuur. Publieke-private vennootskappe (public-private partnerships (PPPs)) kom na vore as 'n alternatiewe manier om infrastruktuur te skep, nie noodwendig as 'n oplossing nie, maar as 'n opsie vir verkryging. PPPs is ook nie sonder probleme nie en een van die probleme wat in hierdie navorsingstudie aangespreek word is die vloei van transaksies. In hierdie navorsing dui die vloei van transaksies (deal flow) op die tempo waarteen PPP projekte in die pyplyn beweeg vanaf die aanvang tot die sluiting van die kontrak. Aanvang beteken registrasie van die projek deur 'n borg institusie by die Nasionale Tesourie van die Republiek van Suid-Afrika en kontraksluiting beteken finansiële sluiting. Finansiële sluiting is die laaste stadium van die projek wanneer finansiële instellings gereed is om geleende geld uit te betaal. Dit volg direk op kontraksluiting, i.e. die stadium wanneer die partye tot die ooreenkoms (regeringsdepartement en privaatsektor) die kontrak onderteken het. Die stadige tempo waarteen transaksies vloei is die onderwerp van hierdie navorsing. Die hoof-doelwit van die navorsing was om faktore te identifiseer wat lei tot 'n stadige vloei van transaksies. Soos in die navorsing bespreek, vind hierdie beweging tans plaas teen 'n tempo van twee transaksies per jaar. Dit is nie goed nie, vergeleke met lande soos die Verenigde Koninkryk waar transaksies gesluit word teen 'n tempo van 50 per jaar. Daar word egter erken dat Suid-Afrika 'n ontwikkelende land is en nie op dieselfde vlak van ontwikkeling is as die ander Europese lande nie. Hierdie vergelyking word dus bloot gedoen met die doel op die vestiging van 'n maatstaf vir toekomstige verwysing. Die ander doelwit was om uit te vind waar die blokkasies in die projek se lewensiklus is met die oog daarop om dit te verwyder of die impak daarvan te verminder. Antwoorde op sommige van hierdie vrae sal nie alleen die Nasionale Tesourie help nie, maar die hele land help om infrastruktuur te skep. Die motivering hiervoor is dat die ontwikkeling van infrastruktuur bydra tot ekonomiese ontwikkeling, ekonomiese groei en die verlaging van armoede en die skep van 'n beter Suid-Afrika vir ons almal. Die hoofbevindings van hierdie navorsing is dat daar 'n groot hoeveelheid tyd spandeer word gedurende die aanvangsfase, naamlik vanaf registrasie van die projek tot by Tesourie Goedkeuring 1 vir die lewensvatbaarheidstudie. In teenstelling met die literatuur wat beweer dat meer tyd altyd spandeer word aan onderhandelings, is dit nie die probleem in Suid-Afrika nie. 'n Aggressiewe dryfkrag met die aanvangsfase is dus nodig. 'n Gebrek aan duidelike regeringsdoelwitte en -toewyding is ook 'n probleem. Swak gedefinieerde sektorbeleide en swak risikobestuur is verdere probleme. Daar is 'n gebrek aan meganismes om langtermyn-finansiering teen bekostigbare tariewe te lok. Hierdie navorsing het getoon dat ander fases in die siklus, naamlik Tesourie Goedkeuring 2A tot Tesourie Goedkeuring 3, nie problematies is nie. Met ander woorde, die fase van nooi, evalueer, aanstel en onderhandel met aanbieders is nie 'n probleem nie en die stadige transaksievloei-probleem kan dus opgelos word as inisiatief geneem word reg aan die begin van konsepsualisering tot en met die fase van lewensvatbaarheid.
