Consequently, the frequency of inspections has been increased to ensure early detection of issues. This proactive approach is expected to reduce the frequency of major replacements, leading to decreased downtime. If the road replacement is postponed the overall disrupting effect onto the whole system is also reduced.<\/p>\n<p style=\"text-align: justify;\"><a href=\"http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2024\/02\/i5.png\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-18669\" src=\"http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2024\/02\/i5.png\" alt=\"i5\" width=\"605\" height=\"271\" srcset=\"http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2024\/02\/i5.png 605w, http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2024\/02\/i5-300x134.png 300w, http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2024\/02\/i5-520x233.png 520w\" sizes=\"auto, (max-width: 605px) 100vw, 605px\" \/><\/a><\/p>\n<p style=\"text-align: justify;\"><strong>Combining Some Systems Maintenance to Reduce Downtime:<\/strong><\/p>\n<p style=\"text-align: justify;\">Scheduling time intense maintenance works like multistory building and rail replacements together leads to overlap which reduces downtime, without disrupting access to other systems.
