This research article proposes a compilation of the best practices necessary to improve the planning of the use of a crane tower in a construction site, evaluating as a case study, the SIDE Project, a high-rise multifamily housing with the incorporation of a POTAIN MC125 crane tower. The methodology applied is based on the analysis of the current planning processes of this machinery together with the problems presented by resident engineers, to then compile the good practices of the main crane tower suppliers in Peru. These were represented with the BIM modeling tool to study their effectiveness in the case study and capture the correct planning process. Finally, these practices were validated through expert judgment by specialists in this machinery. The results obtained in this research are mainly focused on the validation of the proposed good practices, receiving an approval of almost ...

The construction of coastal ports requires the use of materials that meet the demands of the marine environment, to prevent underwater concrete structures from cracking and spalling easily; basalt fiber is used to delay the expansion of concrete and prevent the formation of cracks. This research studies the behavior of concrete for prefabricated piles with Portland Cement Type I and basalt fibers added in 0.1%, 0.3% and 0.6%; the results indicate that the fiber is suitable for concrete, the slump decreases, the compressive strength increases for specimens cured in tap water and sea water, the relationship between resistances does not vary, and the depth of carbonation decreases.

The textile industry has grown significantly in recent years, reaching a global fiber production of 53 million tons which 12 % are recycled; Construction sector has been using more and more recycled materials from different industrial sources, to apply them in their constructions and to reduce CO2 emissions and final energy consumption. The present study aims to study the behavior of concrete blocks of fć= 210 kg/cm2 adding polyester textile waste with 3 %, 6 %, 9 %, 12 % and 15 %; void content, compressive strength and thermal conductivity decrease, and water absorption, acoustic insulation and unit price increase by 3 %, 34 % and 16 % compared to conventional concrete block.
