Technical regulations

Subtítulo sit amet consectetur adipiscing elit.

.
The different European railway administrations have regulatory documents that establish criteria for the design, construction, operation and maintenance of all railway subsystems, as well as others that set out the technical requirements that products to be installed in the various railway networks must meet.

Adif has a process for drafting and approving these regulatory documents based on technical working groups, made up of experts on the different subjects being developed from Adif and Adif AV, which meet under the umbrella of the Regulatory Committee.

Technical Regulations Database

The Regulatory Committee is the executive body, made up of members from both entities, responsible for approving technical regulatory documents; it generally meets every six months.

All documents approved by the Regulatory Committee, as well as repealed documents, are made available to stakeholders on the Technical Regulations (NTW) app. This guarantees the principles of transparency, universal accessibility and equal treatment promoted by current legislation.

Consultation phase

This phase includes proposals for new documents, new or modified versions of existing regulatory documents.

The purpose of the public consultation phase, which lasts 30 calendar days, is to collect, study and evaluate all the suggestions and contributions to the regulatory documents before being sent for approval from the Regulatory Committee at Adif and Adif Alta Velocidad.

Base de Precios de Adif (BPA 2025)

Tras la aprobación en el Comité de Normativa de la norma NAG 9-0-0.1 "Guía de cambios en las unidades de la Base de Precios de Adif", 1ª Edición, y la aprobación de los nuevos precios de mano de obra, materiales y maquinaria el Comité de Actualización de Precios el día 27 de enero de 2025, el día 7 de febrero de 2025 se ha publicado la nueva versión de la BPA que permanecerá vigente desde esta fecha. 

Desde este momento se hace efectivo el uso de la BPA 2025 para todos los proyectos que inicien la redacción a partir de este día, y para aquellos que entreguen maqueta inicial al Área de Supervisión a partir del 7 de mayo de 2025. Los proyectos que se entreguen antes de esta fecha podrán incorporar los nuevos precios a requerimiento del responsable del Contrato, aunque no sea obligatoria su aplicación.

XXVIII Sesión del Comité de Normativa de Adif y Adif AV

En la sesión “ordinaria” celebrada el pasado 12 de diciembre de 2024, se han aprobado una serie de documentos que pertenecen a distintas especialidades y subsistemas: infraestructura, vía, energía, control-mando y señalización, y otros documentos transversales a todas las especialidades (generales).

Merece especial mención, la incorporación de siete nuevos documentos al conjunto normativo y la derogación de un total de 20 documentos (19 relativos a la especialidad de vía y otro perteneciente al subsistema energía).

Gran parte de los documentos que se han modificado, o los que se han revisado de forma integral dando lugar a nueva edición de documentos que ya existían en el conjunto normativo, son consecuencia de la labor encomendada a los administradores de infraestructuras en la Orden TMA/135/2023 por la que se aprueban las instrucciones ferroviarias para el proyecto y construcción de los subsistemas infraestructura y energía (IFI e IFE).
​​​​​​​
Con los documentos aprobados y derogados en esta última reunión se fijan en 75 los documentos revisados y que se consideran adaptados a las nuevas instrucciones ferroviarias. Se avanza en dicha tarea, aunque todavía queda camino por recorrer.

Con el fin de garantizar los principios de transparencia, accesibilidad universal e igualdad de trato, y dar la máxima difusión a las normas, especificaciones técnicas, cuadros de precios, etc., que se aprueban en las reuniones del Comité, Adif pone a disposición de los grupos de interés la Base de datos de Normativa Técnica y Base de Precios de Adif.

Adif Price Base (APB)

In accordance with current Law 9/2017 on public sector contracts, the Administration must ensure that the budgets for the contracts it enters into are in line with market prices. Moreover, Order FOM/3317/2010, of 17 December, approving the Instruction on specific measures to improve efficiency in the execution of public works for railway, road and airport infrastructures of the Ministry of Development, establishes the need to update reference pricing on an annual basis. In order to comply with the above, Adif makes available the following information regarding the Adif and Adif AV Price Base:

The Adif Price Base (APB), integrates the prices of the work units, which serve as a reference for the preparation of projects, works and maintenance of the General Interest Railway Network managed by Adif and Adif AV in the different railway specialities.

Through the Price Base Viewer the prices of all the units that make up the APB can be viewed.
The standardized criteria for using the Adif Price Base, as well as the conditions for the updating and entry into force of said Price Base, are defined in the NAG 9-0-0.0 standard "General criteria for using the Adif price base".
The APB is applicable to all Adif railway subsystems, each of them associated with its corresponding module. The approved criteria, the modifications and particularities of each module are described in standard NAG 9-0-0.1 "Guide to changes in the units of the Adif price base".
