Abstract
This paper presents technical requirements for acceptance of track works according to European standard EN 13231-1, which was adopted as Serbian standard in 2014. The standard applies to track with standard gauge (1435 mm) layed in ballast bed. Requirements for acceptance of works should be applied for laying of the new track, as well as for reconstruction, renewal and maintenance of the existing track. Paper points out that, despite of established legal framework in the Republic of Serbia, national technical regulations are still not harmonised with the requirements of the standard. The special importance is drawn to establishment of the procedures for measuring the relevant parameters and controling the track condition, as well as procedures for documenting measurement results and performed controls. In addition, paper shows prescribed tolerances for track geometry parameters and track superstructure elements according to EN 13321-1. Acceptance deadline has special importance and it should be defined in the contract between Infrastructure Manager and Contractor.
Highlights
Acceptance should occur within a period not exceeding six weeks or after the passage of a maximum of 1,500 000 tonnes after the completion of the works, the customer may extend this timescale to permit any follow-up tamping to be carried out.“ Dakle, na osnovu pomenutog stava iz standarda [3], prijem radova ne treba da se izvrši sve dok se po koloseku ne propusti odgovarajuće saobraćajno opterećenje izraženo u bruto tonama, koje je opisano i definisano od stane naručioca radova
Definisanje krajnjeg roka za izvršenje prijema radova na koloseku u ugovoru od velike je važnosti s obzirom na to da pod saobraćajem propada geometrija izvedenog koloseka u zastoru od tucanika, naročito ukoliko izvedenom deonicom saobraćaju vozila nestandardnih karakteristika
Ako merna oprema nije ispravna ili dostupna, koriste se rezultati merenja lakom opremom za merenje ili opremom za ručno merenje [2]
Summary
Upravlјač infrastrukture (UI) i izvođač radova ugovorom uređuju međusobna prava i obaveze u vezi sa izvođenjem radova na koloseku. Acceptance should occur within a period not exceeding six weeks or after the passage of a maximum of 1,500 000 tonnes after the completion of the works, the customer may extend this timescale to permit any follow-up tamping to be carried out.“ Dakle, na osnovu pomenutog stava iz standarda [3], prijem radova ne treba da se izvrši sve dok se po koloseku ne propusti odgovarajuće saobraćajno opterećenje izraženo u bruto tonama, koje je opisano i definisano od stane naručioca radova. Definisanje krajnjeg roka za izvršenje prijema radova na koloseku u ugovoru od velike je važnosti (naročito za izvođača radova) s obzirom na to da pod saobraćajem propada geometrija izvedenog koloseka u zastoru od tucanika, naročito ukoliko izvedenom deonicom saobraćaju vozila nestandardnih karakteristika Do izvršenja prijema radova na koloseku izvođač je dužan da kolosek održava, kako bi prilikom prijema radova obezbedio vrednosti parametara geometrije koloseka u granicama tolerancije za kolosek u skladu sa [3]
