As a developing country, Peru has great limitations in the application of new and innovative technologies in the construction sector. Construction projects consist of several stages in their development, one of the most important is the planning stage, which is essential to achieve efficient execution and meet established deadlines. However, this stage is usually tedious and complicated to carry out since there are multiple factors that can affect the estimates obtained from the planning process. However, the deadlines for the execution of construction projects are tight and failure to comply generates large losses of money. That is why this article seeks to implement the Lines of Balance (LOB), Last Planner System (LPS) and Building Information Modeling (BIM) methodologies to the traditional procedure. First, surveys were conducted on three different construction projects to determine t...

Multifamily housing projects are developed in different stages of construction, each of which requires a specific site layout. This construction layout is a fundamental tool for planning the physical distribution of temporary installations at the worksite, ensuring order that does not disrupt workflows and maintains productivity. However, one of the main causes of inadequate layout planning is the poor dynamic analysis resulting from using a static layout, traditionally represented in AutoCAD drawings. For this reason, this research focuses on improving the dynamism of site layout planning in multifamily housing projects in Metropolitan Lima; specifically, in the structural stage, using 4D BIM models. The methodology used in this study is developed through the following steps: Analysis of the information gathered from the interviews and surveys conducted with experts; Determination of th...

In multifamily project construction, specialty subcontracting is common, but monitoring subcontractors, especially during finishing, presents significant challenges due to manual methods that are time consuming, make it difficult to detect deviations, and result in cost overruns and delays. This research proposes an automated monitoring procedure using a BIM model that integrates tools such as Revit, Navisworks, MS Project and Trimble Connect. The methodology includes four stages: analysis of information through surveys, identification of the traditional procedure in three companies, development of the new automated approach and validation in a pilot project. The results show a 42.4% reduction in daily monitoring time for subcontractors and a 41.4% reduction for technical personnel, in addition to improved access to real-time information. This optimizes coordination, reduces errors and e...

Nowadays, the construction industry has become the main and great engine of the global economic recovery after the effects of covid-19, generating around 10.7 trillion dollars worldwide, and it is residential construction, specifically, the one in charge of driving growth in the short term, thanks to the constant demand for residential spaces. In this sense, various challenges such as new technologies, the complexity of projects, and a growing competitive environment, force the main contractor to subcontract between 80 and 90% of the activities, thus evidencing that subcontracting is an applied and necessary process in every construction project, and making subcontractors the backbone of the procurement strategy. However, one of the main risks of subcontracting is the inadequate selection of the construction subcontractor, which is often based solely on the criteria of selecting the know...
