Abstract
Purpose
This research proposes the study of the pathology in floor finishes, focussing on proactive maintenance strategies to promote the durability of these elements. A model to assess the floorings' performance levels was designed to support decision-making regarding maintenance activities to be carried out, in order to prevent the defects and extend the floors' service life.
Design/methodology/approach
The model to measure the floorings' level of performance was developed based on the literature and applied in fieldwork, focussed on visual inspections of floor finishes. Photographs were taken and standardized inspection forms were used to collect the data about the defects in the floors.
Findings
This study provides a simple classification model to assess floorings' performance levels, capable to define priorities and help decision-makers in adopting maintenance activities. The model was validated through a case study, which showed that occasionally the choice of the floor finishes is incorrectly made only based on aesthetic criteria and not taking into account the main criteria, i.e. the use of space.
Originality/value
This work contributes to a development of methodologies to assess floorings' performance levels, to study the behavior of different floor finishes, to propose maintenance strategies to improve their performance in service and adopt better solutions in the buildings' design phase.

Abstract
Purpose
The purpose of this paper is to propose a maintenance programme for flat roofs in existing buildings, based on the inspection of 26 buildings in-service conditions, located in the Lisbon region, in Portugal. A proactive maintenance of flat roofs in existing buildings allows reducing their pathology, thus improving their performance and service life.
Design/methodology/approach
The maintenance plan was established based on the degradation state of the maintenance source elements (MSEs) analysed, the aggressiveness of the surrounding environment and the age of the roofs and maintenance actions carried out during the roofing systems’ life cycle.
Findings
The maintenance plan proposed in this study includes the prioritization of the interventions, the definition of the required maintenance operations and the definition of the frequency of the intervention, considering the service lives of the MSEs.
Research limitations/implications
The study addresses only roofs located in the Lisbon area. Even though a relatively large sample of 26 roofs was used, the findings and conclusions can clearly be extrapolated for a much wider scope.
Practical implications
The maintenance plan proposed in this study considers a planning of proactive maintenance operations to continuously and effectively monitor all the relevant MSE.
Originality/value
This plan allows minimizing the incidence and spread of defects, thus enabling the optimization of resources, reducing the costs of the entire maintenance system and improving the quality of the built environment.

Abstract
Purpose
This paper addresses the evaluation of traditional wooden floors, based on (1) visual strength grading (VSG) techniques adopted for ancient wooden structures; (2) a new approach to biological damage and (3) structural safety analysis. This assessment includes complex concepts. Therefore, the study presents a highly needed practical tool to help technicians make a preliminary assessment whereby many of the timber elements in our heritage can be saved from removal.
Design/methodology/approach
A simple and effective procedure was developed for each step. An inspection and diagnosis datasheet was drawn up, and the structural analysis presented by the Eurocodes was summarized. This methodology was then applied in a case study to demonstrate the complete procedure. During the assessment of this sort of structures, the drilling technique was a relevant method utilized as it provided essential and clear information about the beams' conservation.
Findings
The case study results indicate that 70% of the beams of the analysed structure exceed strict minimum performance criteria. This shows that other similar buildings can have their wooden elements saved from demolition, which is not the current regular refurbishment approach.
Originality/value
The current reality shows that the technicians' lack of capacity for a pragmatic assessment of the timber members’ structural capacity promotes their disinterest in them. To avoid that, this text presents a process for evaluating wooden floors using a simple and clear approach. This will prevent the demolition of wooden elements and instead encourage their preservation.

Abstract
Purpose
This paper aims to contribute to the discussion of the following questions: How can the digital transition improve the management of the operation and maintenance of infrastructure in health-care facilities? What is the legacy for facility management (FM) teams in this post-COVID-19 management of hospital buildings?
Design/methodology/approach
Based on a literature review, this paper analyses and categorises existing research on the digital challenges for FM from 2011 until 2021 by conducting a qualitative and quantitative method of bibliometric analysis and discussing the status of digital transition impact on FM of the hospital buildings.
Findings
The trends and challenges of building information modelling, artificial intelligence and the Internet of Things identified and discussed in this paper aim to be as comprehensive as possible to grasp the situation of digital transition in the FM industry in the hospital buildings context. Regarding digital maturity, the limited number of publications highlights that control and management systems cannot fully manage the entire operational phase of hospital buildings. Giving intelligence to buildings will undoubtedly be the future. So making buildings reactive, interactive and immersive is an inevitable transformation for intelligent hospital building systems. Thus, the added value of digitalisation will help facility managers to overcome the issues pointed out in this paper to deal with the growing health demands and enable them to mitigate the impacts of a new and future pandemic.
Originality/value
The novelty of this paper is classifying and unifying facility managers' tendencies regarding high-level information management issues, which are lacking in the literature, with a focus on the approaches with potential and higher impact on FM in the hospital building context and the related steps that should be considered regarding data collection and data structures. These tendencies provide a set of new intelligent approaches and tools, which will increase the efficiency of processes, significantly impacting the potential of optimisation. Also, these trends can improve planning and management of scope, costs, environment and safety in the value chain of projects and assets, thus creating a more resilient and sustainable industry for facility managers in this post-COVID-19 management for hospital buildings.

Abstract
Purpose
The Covid-19 pandemic highlighted the contradictions inherent to balconies. Despite the attention given to these architectural elements on that moment, there is a knowledge gap concerning the preferences and expectations of the inhabitants in relation to them. For this reason, this paper aims to conduct a critical literature review of the publications about the inhabitants’ perceptions of balconies in order to identify the most relevant criteria to consider during the design process.
Design/methodology/approach
The analysis was based on the post-occupancy evaluation (POE) criteria (technical, functional and behavioural).
Findings
The results highlighted the relevance of the behavioural criteria for the valorisation of the balconies by the inhabitants and presented indications to the research about these liminal spaces and the design practice of housing buildings.
Originality/value
According to the authors’ best knowledge, this study represents the more holistic study of the kind.

Abstract
Purpose
The purpose of this paper is to present a methodology in order to improve inspections' diagnosis during façades' service life through in‐service criteria. On‐site performance assessment and deciding on the maintenance of renders can only be improved if quantitative parameters are pre‐established at the design stage and monitored under service conditions.
Design/methodology/approach
The methodology is based on a set of in‐service parameters inferred from visual observation and measurements and their methods of assessment (based on visual inspections, auxiliary techniques, in‐situ and laboratorial testing). These have been arrived at by inspecting the façade rendering on 44 buildings (cement‐based renders), of different ages and types of degradation.
Findings
This paper focuses on 23 proposed mechanical and physical‐chemical parameters that can complement the ones already established by standards or technical data, obtained in lab conditions, using standard specimens or small models. They are assessed by techniques that have been applied to renders or other façade elements such as concrete or timber structures. The reliability of this in‐service performance assessment is discussed together with its potential as an aid to deciding on predictive maintenance action after an inspection's diagnosis.
Originality/value
The originality of this approach stems from the fact that in‐service parameters derived from both laboratory and in‐situ measurements can improve understanding of the behaviour of façade rendering, which is an important step in planning and monitoring maintenance. Two aspects are emphasised: the behaviour of materials/systems is assessed in real conditions, and the subjectivity of in‐service diagnosis is reduced when more than one performance parameter is assessed.

Abstract
Purpose
The purpose of this paper is to analyse two parameters relevant to the physical‐mechanical performance of external renders, mainly, bulk density and apparent or open porosity, by performing laboratory tests on samples collected under real in‐service conditions.
Design/methodology/approach
The test procedure (sample preparation and techniques used) and its relationship with the overall performance characteristics and with any anomalies are discussed for each parameter. The analysis of the results covers seven case studies and 15 walls with renders made on site (cementitious and cement‐lime based) and non‐traditional or pre‐mixed renders.
Findings
It was concluded that reliable relationships could be established between the test results and other physical parameters relevant to the mechanical and water‐related behaviour of different types of cementitious renders. Notwithstanding the usual drawbacks of laboratory tests (more time‐consuming, higher costs and greater destruction of the walls), the use of small samples and the additional data obtained in terms of in‐service performance justify the use of this type of test.
Originality/value
The originality of this approach comes from the advantage of conducting both laboratory tests (reliability and standardization) and in situ tests (testing real materials subjected to in‐service conditions). Current practice is either to test virgin materials in quasi‐perfect laboratory conditions (therefore far from reality) or to test materials on site using standard in situ techniques sensitive to subjectivity and in far from ideal environmental conditions.

– The purpose of this paper is to present a proposal for a methodology to support the rehabilitation project of renders of old buildings.
Abstract
Purpose
The purpose of this paper is to present a proposal for a methodology to support the rehabilitation project of renders of old buildings.
Design/methodology/approach
To achieve the objective it was considered essential to define the main types of participants and aspects to integrate the proposal. The research methodology consists in an inquiry presented to several professional participants in rehabilitation, a market study of materials and products available in Portugal, the design of a methodology proposal and its application to a case study. The inquiry sample totals 24 answers from the targeted professionals. A sequence of relevant supporting procedures consists in the proposal, which aims to provide a supporting methodology to decide and project in this context and also to be tested with its application to the building. This proposal was applied to an old building with load-bearing stone masonry walls and air-lime-based renders.
Findings
It was concluded that the assessment of the building and ex+ternal renderings’ condition, its diagnosis and of the supporting walls, the definition of intervention, the specification of materials to be used and performance requirements to comply, and also plans for conservation and periodic maintenance, are crucial. From the inquiry, compatibility between materials and complementary roles and points of view of different types of participants in rehabilitation must be highlighted.
Originality/value
A proposal for a methodology to support the project could provide useful guidance particularly for architects and construction engineers, and improve the understanding of direct participants on site, therefore contributing for the correct implementation of the intervention.

Abstract
Purpose
The purpose of this paper is to gain insight into facility management in Portugal as well as in Europe and what a facility management study programme must entail in Portugal in order to implement this.
Design/methodology/approach
The paper describes the mixed-methods approach. Both qualitative and quantitative methods are used based on extensive literature research of the subject. Semi-structured interviews were held with ten professionals from the FM field. The quantitative method was in the shape of a questionnaire sent to 40 professionals in Europe.
Findings
The results show that Portugal is not on the same level as the rest of Europe when it comes to FM. Also, FM is rather of a technical nature and lacks service orientation and managerial elements. Moreover, Portugal should first focus on creating awareness about the field of FM and provide FM study programmes accordingly. Research shows that this could be a lengthy process.
Originality/value
Currently there is no facility management study programme offered in Portugal. However, by gaining insight into this field and how facility management is of great added value to the market, a step closer to implementing a study programme is taken.
