ENGLISH ABSTRACT: Alternative construction methods have become increasingly popular in the construction industry amid growing pressure from the global community for the industry to do more towards sustainability. While the adoption of alternative construction methods has been touted as the answer to the sustainability call, these methods come with their own challenges. Decision-makers in the construction industry were suddenly overwhelmed by a plethora of new methods to choose from, with a vast number of factors to consider, making it increasingly difficult to choose an appropriate method for their projects. This study set out to develop a decision-support framework that would allow decision-makers in the alternative construction industry to make informed decisions regarding which methods to use when constructing patient-serving healthcare facilities in sub-Saharan Africa. To achieve this, two systematic literature reviews were performed on the topics of alternative construction methods and life cycle sustainability analysis. Based on the knowledge uncovered during the reviews, a set of requirement specifications was defined for the framework, and a list of impact categories for life cycle sustainability assessments was compiled. Care was taken to ensure that these specifications and categories were all relevant to the sub-Saharan Africa scope of the study. Once the initial lists of requirement specifications and impact categories were established, subject matter experts were consulted through semi-structured interviews to verify the lists and make recommendations for improvement. The lists were then adapted and finalised based on the feedback received. As this point in the study, the decision was made to alter the scope of the study based on what had been uncovered in the literature reviews and interviews with experts. Since the decision-factors and requirement specifications proved to be more reliant on the geographic location of a project as opposed to the type of facility that was going to be constructed. As a result, the scope of the study was shifted to incorporate facilities built in sub-Saharan Africa in general as opposed to healthcare facilities specifically. The development of the framework then commenced based on these verified lists and the adapted scope. The resulting framework consists of 6 steps, each defined with its own inputs, processes, tools, skills and outputs. Life cycle sustainability assessments pertaining to environmental, economic, and social factors were all identified as necessary tools to implement when assessing possible alternative construction methods. Furthermore, the framework also considers factors such as government incentives and policies, risks, challenges, and benefits associated with a specific method. The framework also guides the decision-maker on how to assign scores for each method in order to rank possible options and finally choose an appropriate construction method. Upon its completion, the framework was self-verified against the list of requirement specifications and also verified and validated by subject matter experts, again utilising semi-structured interviews. Some of the noteworthy contributions of the study include the structured and scientific approach to the decision-making problem as it relates to alternative construction methods and the balance struck by the developed decision-support framework in simplifying the problem while adding the needed complexity for accurate analysis. Notable future work recommended from this study is the implementation of the decision support framework through case studies in sub-Saharan Africa to develop and strengthen the framework further. AFRIKAANSE OPSOMMING: Alternatiewe konstruksiemetodes het toenemend gewild geword in die konstruksiebedryf te midde van toenemende druk van die wˆereldgemeenskap op die bedryf om ’n groter bydrae te lewer wat volhoubaarheid betref. Alhoewel alternatiewe konstruksiemetodes toenemend aanvaar word as ’n oplossing vir beter volhoubaarheid in die konstuksiebedryf as geheel, bring hierdie metodes hul eie uitdagings met hulle saam. Besluitnemers in die konstruksiebedryf is basies oornag oorweldig met ’n oorvloed nuwe metodes om van te kies, met ’n groot aantal faktore om in ag te neem, wat dit baie moeilik maak om ’n toepaslike metode vir hul projekte te kies. Hierdie studie het beoog om ’n besluitnemingsondersteuningsraamwerk daar te stel wat besluitnemers in die alternatiewe konstruksiebedryf in staat sou stel om ingeligte besluite te neem oor watter metodes om te gebruik wanneer pasi¨entbedienende gesondheidsorgfasiliteite in sub-Sahara-Afrika gebou word. Om hierdie doel te bereik, is twee sistematiese literatuurstudies uitgevoer wat gehandel het oor die onderwerpe van alternatiewe konstruksiemetodes en lewensiklus-volhoubaarheidsanalise. Gebaseer op die kennis wat tydens die studies aan die lig gekom het, is ’n lys spesifikasies vir die raamwerk saamgestel, asook ’n lys impak-kategorie¨e vir lewensiklus-volhoubaarheidsassesserings. Hierdie spesifikasies en kategorie¨e is so opgestel om te verseker dat almal relevant sal wees in ’n sub-Sahara-Afrika konteks. Nadat die aanvanklike lys spesifikasies en impak-kategorie¨e vasgestel is, is kundiges op die gebied deur middel van semigestruktureerde onderhoude geraadpleeg om die lyste te verifieer en aanbevelings vir verbetering te maak. Die lyste is daarna aangepas en gefinaliseer na gelang van die terugvoer van die kundiges. Op hierdie stadium van die navorsing is die besluit geneem om die omvang van die studie te verander gebaseer op wat tydens die literatuurstudies en onderhoude met kundiges aan die lig gekom het. Hierdie aanpassing is gemaak angesien die besluitnemingsfaktore en spesifikasies klaarblyklik meer afgehang het van die geografiese ligging van ’n projek eerder as die tipe fasiliteit wat gebou sou word. As gevolg hiervan is die omvang van die studie aangepas om enige fasiliteite wat in sub-Sahara-Afrika gebou word in te sluit eerder as om slegs op gesondheidsorgfasiliteite te fokus. Die ontwikkeling van die raamwerk het toe geskied op grond van hierdie geverifieerde lyste en die aangepaste omvang. Die proses het gelei tot ’n raamwerk wat bestaan uit 6 stappe, elk met sy eie insette, prosesse, hulpmiddels, vaardighede en uitsette. Lewensiklus-volhoubaarheidsassesserings wat fokus op omgewings-, ekonomiese- en sosialefaktore is almal ge¨ıdentifiseer as nodige hulpmiddels om te gebruik wanneer moontlike alternatiewe konstruksiemetodes geassesseer word. Verder oorweeg die raamwerk ook faktore soos regeringsaansporings en -beleide, risiko’s, uitdagings en voordele wat met ’n spesifieke metode verband hou. Die raamwerk lei ook die besluitnemer om punte toe te ken vir elke metode om moontlike opsies te rangskik en uiteindelik ’n toepaslike konstruksiemetode te kies. Nadat die raamwerk voltooi is, is die raamwerk geverifieer teen die lys spesifikasies en is dit ook deur kundiges op die betrokke gebied geverifieer en gevalideer. Vir die proses met die betrokke kundiges is daar weer gebruik gemaak van semi-gestruktureerde onderhoude. Sommige van die noemenswaardige bydraes wat die studie maak tot literatuur en die bedryf sluit in, die gestruktureerde en wetenskaplike benadering tot die besluitnemingsprobleem met betrekking tot alternatiewe konstruksiemetodes, asook die balans wat die ontwikkelde besluitnemingsondersteuningsraamwerk bereik het deur die probleem te vereenvoudig terwyl die nodige kompleksiteit vir ’n akkurate analise behou is. Toekomstige werk wat uit hierdie studie spruit, is die implementering van die besluitnemingsondersteuningsraamwerk deur middel van gevallestudies in Sub-Sahara-Afrika om die raamwerk verder te ontwikkel en te versterk.
