Academics have been devoting a growing attention to different matters involving public-private partnerships (PPPs), and, as the use of PPPs for delivering infrastructure evolves worldwide, so does the number and type of papers addressing this procurement model. The objective of this paper is to undertake a comprehensive literature review of papers relating to PPPs and private finance initiatives (PFIs), using a bibliometric analysis. More than 600 papers published between 1990 and 2014 were examined. None of the previously existing studies analyzed such a large sample of papers. The research found that PPP studies appear to have a steady momentum toward growth. Engineering journals (and engineering as a research area) have been particularly active in this field. Authors based in Europe and Asia had written almost two-thirds of the papers, with transportation and health sectors at the top of sector-based papers. Most of the existing work is focused on aspects of contract design, risk sharing, and a...

The increased use of public–private partnerships (PPPs) around the world to build infrastructures and provide public services has led to several concerns. One of the main pitfalls of PPPs is an abnormal frequency of renegotiations, especially renegotiations occurring during the first years of contract. The Latin American experience has been the most relevant in terms of research on PPP renegotiations. Using the literature on PPP renegotiations in the Latin American context, this article focuses on the analysis and discussion of renegotiations. We use the experience from Brazil, at the State (region) level, of PPPs and renegotiations. From 2006 to 2016, Brazil developed 42 PPP projects in several sectors. From these, 27 were renegotiated at least once. We found a high number of renegotiations within a short period since the start of the contract for the first renegotiation to occur. The motives for renegotiations are mainly perceived from the public sector, particularly failure in planning, concept, and bidding. Electoral periods and the political connections of shareholders also have an impact on renegotiations. Based on the Brazilian experience, we drawn some policy implications.

Governments have used public–private partnership (PPP) units to ensure that PPP programs and projects are successfully delivered. These units frequently are understaffed and vulnerable to political and economic pressure to deliver. Few researchers have examined the organization, size, and transparency of these units. This paper undertakes a comparative analysis of 27 Brazilian federative units. The research has been focused more on identifying governance characteristics, and this study includes indicators of success, such as project implemented and transparency level. The research concluded the following: (1) Brazilian PPP units still have to significantly improve PPP public transparency; (2) a reduced number of PPP projects is actually implemented, but the more transparent PPP units are those with the ability to successfully implement more projects; and (3) size matters in terms of staff—the larger the units are, the more projects are implemented and the better the conversion ratio (projects appraised versus projects in operation).

A análise do perfil dos seguidores nas redes sociais é fundamental para o marketing digital das empresas de engenharia civil. Este estudo investigou as estratégias de marketing digital em construtoras na região do Cariri cearense, dividido em duas partes. Foi analisado o perfil dos usuários do Instagram de uma construtora local e comparados métodos de marketing com outras empresas da região. Objetivos específicos incluíram avaliar segmentações demográficas e geográficas, identificar a presença digital da construtora e verificar a viabilidade do marketing digital. A metodologia incluiu revisão bibliográfica, análise de dados do Instagram e um formulário aplicado a construtoras locais. Os resultados indicaram aumento no engajamento e alcance da construtora estudada, com diferença de mais de 10% entre os usuários masculinos e femininos, e maioria dos seguidores na faixa etária de 25 a 34 anos. A maioria das construtoras utilizam o Instagram como principal rede social, mas muitas não empregam profissionais especializados, enfrentando dificuldades como falta de tempo e conhecimento em ferramentas de marketing. A pesquisa destaca a evolução do marketing na construtora estudada e a preferência dos usuários por conteúdos em formato de vídeos curtos.

O setor da construção civil é fundamental para a economia brasileira, mesmo em períodos de crise, dada sua significativa contribuição para o Produto Interno Bruto e o estímulo ao crescimento de setores correlatos. No entanto, a deterioração precoce de edifícios, frequentemente resultante de falhas construtivas ou problemas patológicos, desafia a qualidade e durabilidade das construções. Este estudo busca quantificar o impacto das manifestações patológicas nos orçamentos de reparo de três edificações públicas em Juazeiro do Norte/CE – UBS Vila Três Marias, UBS Socorro e UBS Betolândia –, destacando as consequências financeiras de obras interrompidas. A metodologia inclui coleta de dados por vistorias técnicas e documentação fotográfica, classificação das manifestações patológicas, recomendação de medidas corretivas e análise de custos para quantificar o impacto financeiro das deteriorações. Os resultados revelam que projetos paralisados não apenas atrasam a entrega de infraestruturas essenciais, mas também acarretam custos adicionais, indicando lacunas na gestão de projetos e previsão de contingências. A UBS Vila Três Marias foi a mais afetada, sugerindo problemas graves ou lacunas na construção inicial. Infiltrações e deformações excessivas foram as principais causas de custos adicionais, ressaltando a importância de planejamento e orçamentação cuidadosos na infraestrutura pública para evitar custos elevados de reparo.
