The Impact of Temporary Means of Access on Buildings Envelope’s Maintenance Costs

Accessibility to buildings’ envelope depends on efficient inspection and other maintenance actions of their components. When access to these components is not planned, special means of access are required to carry out the maintenance work. Means of access, besides having a fundamental role on the quality of maintenance works of building envelope components, also represents a considerable part of the maintenance costs. Thus, to optimize costs and resources in maintenance plans, assessment of the impact of the means of access on maintenance costs is crucial. For works in height, there are several alternative means of access. The choice of the most adequate solution is strongly linked to the characteristics (e.g., architecture, height) and constraints (e.g., users, surrounding space) of each building, the maintenance needs of the envelope, and the time and funds available for the intervention. Therefore, in this study, a sensitivity analysis to understand how the cost of means of access can influence the maintenance costs is carried out. Moreover, the optimisation of maintenance activities in façade claddings is also analysed. This study intends to assess whether it is advantageous to consider permanent means of access during the design phase or opt for temporary means of access. In a first stage, the impact of six temporary means of access (supported and suspended scaffolds; articulated booms; telescopic booms; scissor lifts; and rope access) on the maintenance plans developed for the six types of claddings (ceramic tiling systems—CTS, natural stone claddings—NSC, rendered façades—RF, painted surfaces—PS, external thermal insulation composite systems—ETICS, and architectural concrete façades—ACF) is examined. The impact is estimated through a stochastic maintenance model based on Petri nets. After that, a sensitivity analysis and a multi-criteria decision analysis are performed. Based on the results, general recommendations are presented concerning the maintenance strategies to adopt in the cladding solutions analysed. The results reveal that planning the means of access during the design stage can be economically beneficial for all buildings’ envelope components.

In the paper there was considered polyspast system as a means of personal protective equipment against falling from height. The structural place of these products in the classification of protective equipment, their functional purpose in ensuring the safety of work at height is analysed. The issue of statistics of accidents at work at height is touched upon. The relevance of the issue of continuous work on safety in this sector of work is shown. There are similarities in the need for safety and rescue operations in both the sports and industrial sectors. The purpose of this work is to form competent recommendations on various aspects of certification and certification tests of polyspasts to improve the safety of users, athletes (including children) and rescuers when performing various tasks and work at height. Within the framework of this work, the procedures for forming technical requirements for certified products, the totality of interaction of the main technical requirements of the technical regulations with the lists of standards specified in the Appendix to the technical regulations are considered. The analysis of two examples of polyspasts, certified in the market of the Eurasian Customs Union. The weak points of their certification due to the problems of the normative and technical state of the main documents in this area are shown. The conclusions provide a brief analysis of the problems of certification and certification testing of polyspast systems. Recommendations of both structural and local nature are formulated to improve the safety of certified products.

This article considers static ropes - one of the components of a personal fall protection system when working at heights. The issue of accidents when working at heights in Russia and abroad is raised. The inspection of the ropes is considered as one of the local mechanisms to reduce injuries when performing work at heights, as well as the advanced training of specialists responsible for the inspection of personal protective equipment against falling from a height. The effect of acid solutions most commonly encountered in industrial activities with short-term contact and with prolonged contact on polyamide ropes is investigated. Recommendations are given for a more competent use of these products in various situations without compromising safety. The questions of solving the problem of the hidden effect of acids on static ropes with a polyester sheath are raised.
