ABOUT

Banagher Precast Concrete Limited has provided precast concrete solutions and components to the building industry for over 30 years. We have been involved in some of the largest multi-story frame projects in Ireland

Our responsibilities generally consist of the design, manufacture and installation of precast double tee flooring slabs which span large distances between precast spine beams which are in turn supported by precast columns. The only element constructed on site is the floor screeds. As the units are designed on a job by job basis, the system can be tailored to suit the specific requirements of each customer or contract.

Banagher Precast Concrete has developed a reputation for efficient concrete design using the latest prestressing, posttensioning and high strength concrete technology. We are ISO 9001 approved and all Precast Concrete elements designed, manufactured and installed by Banagher Precast Concrete are manufactured to the highest quality standards.

The versatility of design and the experience of our engineers ensure that our double tee flooring can be adapted for a wide range of applications from reservoirs, buildings, transfer floors, car parks to walls and footbridges.

Double Tee flooring can even be skewed to allow for abnormal frame conditions.

Benefits of Precast

The considerable advantages of precast construction are combined with the inherent benefits of concrete to provide a superior construction product.

These include:

  • Inherent Fire Properties – Concrete has its own inbuilt fire resistance which is present during all construction phases. Precast frames are generally designed for one hour inbuilt fire rating. This either totally eliminates or greatly reduces the need for additional fire protection and the associated costs.
  • Reduced Construction Programme – Due to speed of construction, gives earlier return on investment, freeing up the project critical path and allowing earlier completion. It is estimated that a precast structure takes up to 20% less time to construct than a similar cast in situ structure.
  • Greater Project Control from a completion/project management perspective and from a costing perspective.
  • Factory Production ensures increased accuracy and quality of finish and decreases weather dependency. Compared with cast in situ structures, site labour is reduced by between 50% and 80% using precast. Work for following trades is reduced by between 30% and 50% depending on finishes.
  • Buildability – Precast frames can greatly improve buildability because sensitive parts of the operation can be moved from the site to the factory.
  • Larger Clear Spans – Reducing the number of columns is critically important in developments such as sports stadia and car parks. Longer spans and shallower construction depths can be obtained by using prestressed concrete beams and floors.
  • Proven Designs and Methodologies – Precast frame design incorporates proven designs and methodologies which have been developed over many years.
  • Composite Action – Prestressed precast elements act compositely with an in situ structural screed (topping), combining the benefits of precast and in situ construction.
  • Less Wastage – Precast systems significantly reduce the amount of waste materials produced on site.
  • Loose Reinforcement – The amount of loose reinforcement on site is reduced by between 80% and 90%.
  • A Complete Service from design to manufacture to installation is available.

Quality & Accuracy

Precast concrete units are manufactured in factory conditions where strict manufacturing controls apply. This ensures that reinforcement bars are accurately located and that clients receive high quality products manufactured to controlled dimensional tolerances. Precast concrete delivers a high performance product with a quality appearance.

Speed of Construction & Buildability

Speed of construction and tight construction programmes are primary considerations in most building projects and this is where precast concrete excels.

Choosing a Construction Method – Comparative Costs

Savings through factors such as earlier completion dates, inbuilt fireproofing, reduced formwork, scaffolding, reduced wet trades and increased budget control can be significant. Also, fast-track procurement and construction may minimise capital costs by reducing financing costs and securing earlier rental income.

Sustainability

Most of the sustainable developments throughout Europe use concrete as the primary construction material. Concrete is long lasting and requires virtually no maintenance or replacement and does not require the application of toxic paints or preservatives. Even highly exposed precast concrete units (such as box culverts) are virtually maintenance free and have a design life of 120 years. Concrete is 100% recyclable and is generally supplied (in Ireland) within a 30 mile radius, with the resultant savings in transport costs and fossil fuels.

Thermal Capacity

Concrete has excellent sustainability credentials allowing for a reduction in the use of fossil fuels and greenhouse gases. By using concrete as a passive moderator, there are enormous potential savings as 90% of the energy consumed in the life cycle of the building is attributable to heating and cooling.
