What is BS EN 15050 - Precast concrete bridge elements about?  
Precast concrete is changing the way construction is approached. BS EN 15050 is a European Standard that discusses precast concrete products.
BS EN 15050 applies to precast concrete structural elements produced in a factory and used in bridge construction, such as deck elements.
The evaluation of conformity given in BS EN 15050 refers to the completed precast concrete elements for bridges that are supplied to the market and cover all the production operations carried out in the factory.
Note: Foundation piles, piers, abutments, barriers, bumpers, guards, arches, and" box culverts are out of the scope of BS EN 15050.
Who is BS EN 15050 - Precast concrete bridge elements for? 
BS EN 15050 on precast concrete bridge elements is useful for: 
- Relevant government / municipal authorities that commission work
- Public works divisions
- Highway / roadway authorities / road transport authorities
- Manufacturers and suppliers of precast concrete blocks
- Product development / innovation teams
- Quality control teams
- Project managers / site managers
- Civil engineers
- Construction contractors
- Real-estate builders / developers
Why should you use BS EN 15050 - Precast concrete bridge elements?  
Precast construction blocks are preferred because they are prepared, cast, and cured in the factory. BS EN 15050 discusses precast elements produced in a factory or near the construction site in a place protected from adverse weather conditions. BS EN 15050 guidelines are for elements that assure the same level of quality control, even if not manufactured in a factory.
For design rules and resistance to fire, reference is made to EN 1992-1-1 and EN 1992-1-2. Additional complementary rules are provided where necessary.
BS EN 15050 includes specific provisions resulting from the application of EN 1992-1-1, EN 1998-1, EN 1992-1-2, and EN 1992-2 rules made specifically for the concerned product. The use of these provisions is consistent with a design of works made with EN 1992-1-1, EN 1992-1-2, and EN 1992-2.
Some of the elements are also treated in other European Standards (e.g., beams, slabs). BS EN 15050 deals with the specific aspects related to the use of these elements in bridge construction.
Overall, BS EN 15050 makes it easier to regulate the quality and longevity of your concrete elements. Factory-cast and cured construction blocks reduce air pollution, noise and debris.
