Regulatory requirements applicable to bollards
The entry into force of a new Spanish accessibility regulation has raised doubts about whether the pedestrian areas in a project that got approved previously to the new law meet all the requirements. ITeC has been asked to set down what parameters bollards for pedestrian areas must meet according to the latest versions of country, regional and local regulations.
Smile City project: better urban bicycle mobility infrastructure
The SMILE CITY project develops innovative construction solutions for deploying the network of bicycle lanes and electric bicycle charging stations, reducing their environmental impact and making them safer for users. They include prefabricated concrete and rubber elements that reuse different types of urban, industrial and construction waste. The demonstration phase contemplates the construction of 100 km of bicycle lanes and 20 electric bicycle charging points.
Database for urban telecommunication networks projects
A public entity that uses ITeC’s BEDEC database to contract street construction and maintenance works for the assets under its responsibility has new needs in works related to telecommunications and data networks, and has requested improvements in the database to meet these needs.
Groundwork for virtual testing of a range of modular expansion joints for road bridges
The assessment of such an expansion joint requires, among other things, to elaborate a 3-D Finite Element (FE) model of the joint to identify its dynamic behaviour: natural frequencies, section forces and bending moments. The manufacturer has asked ITeC to specify the requirements of the FE model to make sure that is in conformity with EAD 120113-01-0107 ‘Modular expansion joints for road bridges’.
Protocol for testing earth anchors for slopes
Drafting of a set of laboratory test specifications for earth anchors for slopes, modelled on the EN 795 standard. A test will be carried out in order to verify whether the protocol adequately covers all the installation details of the anchors, the measuring instruments and load application.
Implementation of the BIM methodology in a roadway project
A contractor has been awarded a road project and the contracting authority requires BIM to be used in the key phases of the work. ITeC has provided advice to create, update and manage the BEP (BIM Execution Plan), to make a pre-construction BIM model, to monitor the execution process with BIM monitoring and finally to deliver the as-built BIM model of the road.
Database of prices, specifications and environmental parameters for work in natural environments
A public entity is contracting works to be carried out within a the natural areas under its responsibility, such as forest maintenance, equipment maintenance, fire prevention or restoration of degraded spots. The construction databases used for budgeting and tendering public works do not cover in sufficient detail these types of works in natural environments, so ITeC has been entrusted with the mission of creating a specialized database that fills these gaps.
Requirements for the fasteners used in grounding connections in transport infrastructures
Mechanical fixings used in transport infrastructures must keep their properties in unfavorable conditions, which get even worse if they are part of a grounding electrical circuit. In order to clarify the regulatory status of these elements, an analysis of the relevant regulations has been performed, including the technical specifications and conditions of use.
Requirements for ventilation dampers for tunnels
When a tunnel exceeds a given length, it is compulsory to install mechanical ventilation systems that should remain operative in the event of fire in order to remove smoke and hot gases. Regulations are somewhat ambiguous in relation to the type of requirements and specific conditions that may be requested from ventilation systems during a fire, considering that it is not necessary to treat them like fire doors in building compartmentalization. This report aims to identify the criteria to be followed for a harmonised assessment of these products and for their certification.
Assessment of post-tensioning systems for concrete structures
The evaluation of the post-tensioning systems as per ETAG 013 includes not just the elements to place under tension (cables, bars or tendons) but the whole set of components that are needed on site. This "kit" approach means that the analysis must include connectors and couplings, ducts, trumpets and filling materials.
