Restoration and preservation of historic structures is vital to maintaining and promoting the heritage of any community. Historical properties such as houses of worship, palaces, government buildings, courthouses, museums, etc. often require repair and restoration. Many of these buildings, for example, require upgrading to current seismic standards. General aging and deterioration may be another reason for such repairs. In all cases, care must be taken not to change the historic appearance of the structure and satisfying the needs of the various historic society committees and review boards can become challenging at times.
Our engineered Fiber Reinforced Polymer (FRP) solutions offer fast, long-lasting and economical repair alternatives to owners, architect/engineers and contractors to ensure the project is completed on time, within budget and with minimum disruption of service. Products such as Near Surface Mounted (NSM) carbon strips can be hidden inside grooves that are cut in walls, totally making the repairs inconspicuous. Afzir carbon fabrics hat are less than 0.05 inch (1.3 mm) thick can be applied to wall surfaces and covered with various architectural coatings; these solutions are much more suitable for retrofit of historic buildings compared with the use of conventional methods that utilize large steel beams and columns or encasement in concrete.
Some of the repair, strengthening and preservation projects of historic that can benefit from Afzir engineered FRP solutions are:
- Strengthening of floors, beams, columns and walls as a result of change of use in existing buildings, e.g. when a floor is converted to a museum supporting heavier artifacts
- Seismic strengthening of concrete and masonry walls
- Repair of corrosion damaged columns, floors, stairways, etc. using FRP products
- Blast retrofit/mitigation or force protection of historical structures against terrorist attacks
- Repair of underground tunnels that are damaged by corrosion
- Trenchless repair of pipelines and tunnels using FRP composite
In most cases, Afzir engineers can provide a complete “turnkey” design-build solution that includes sealed engineering drawings by our in-house engineers, all of the materials needed, and installation by one of our approved and certified installers. This unique turnkey design-build approach results in significant efficiency, time and cost-savings, and minimizes the potential errors and delays that can result when multiple groups are involved in one project.
Afzir also welcomes the opportunity to partner with owners, architects, engineers and contractors by providing any single aspect of the project, i.e., design, materials, or installation for a specific project.
