This article examines in particular which are the risks inherent in any construction project, and from them, explains the risk assignment method used in traditional construction contracts, noting that it does not adequately solve the allocation of risks and attribution of blame, making construction projects more expensive. In response to how to face these difficulties, this paper studied the collaborative contracts, their common elements, classes and the way in which risks are distributed, making a detailed analysis of the collaborative contract par excellence, that is, the alliancing or Integrated Project Delivery, to finish carrying out a particular examination of how risk assignment is treated in standardized international construction contractual models, such as FIDIC, NEC and FAC-1 contracts.

One of the most important aspects of construction projects are their variations. These are situations that generate a series of negative consequences for those involved and constitute the breeding ground for claims and controversies, are inevitable in the construction industry. In the present article we will analyze two fundamental questions about variations: their conceptual delimitation and its causes. In general terms, we believe that a better understanding of the phenomenon will allow providing adequate and coherent solutions to the problem. The importance of this article derives from the vacuum at the legislative, doctrinal and jurisprudential levels in Peru. In effect, the regulation of the work contract contained in the Civil Code does not devote an organic treatment to variations. However, certain provisions of the mentioned normative body (as well as others included in se...

In recent decades sandwich composites have taken a greater share in the construction industry, due to their low cost and properties that characterize these composites. Among the most important properties of these, the thermal conductivity stands out, which is directly linked to the individual's thermal comfort in a building. Currently, the Peruvian State has been developing projects in the fight against frost and cold, where one of the main interventions focuses on the construction of sustainable homes that can help the high Andean population cope with the inclement cold. In this sense, it is necessary to have construction materials appropriate for the climatic conditions of the place, and that is where lies the importance of this research. This paper proposes the study of thermal conductivity at temperature conditions close to 0 ºC of sandwich composites formed from monolithic material...

Essentially, the loss suffered by the global construction industry during the time when the COVID-19 is spread is not caused by that pandemic itself but caused by a changed circumstance which mainly resulted by anti-COVID-19 policy or law conducted by different jurisdictions. Where contract keeps silent in this regard, legal solution should be made by contemplating the law in different jurisdictions toward changed circumstances, which commonly includes situations where performance of contract become more onerous or impossible, and taking account of the factual environment which determines or impacts the changed circumstance. This paper, from a comparative law perspective, discusses and concludes the doctrine of changed circumstance in some typical jurisdictions, and, by taking consideration of law and fact, provides some approaches and potential legal solutions to deal with that loss.
