A Resource for Bleacher and Grandstand Knowledge

How do I know if my existing bleachers need to be replaced or can be repaired?

This depends on several factors: the age of the structure, the condition of the footings, the condition of the supporting members, and  code compliance. Before making refurbishing vs. replacement decisions, it is advisable to have a structural engineer inspect the supporting structure including foundation.  If it is structurally sound, the  next step  is to have an architect or other qualified individual review code compliance and cost to make repairs.

What is the typical lifespan of aluminum planked angle frame  bleachers?

Properly maintained aluminum planked angle frame bleachers typically last 30 to 40 years. The structural components — the aluminum planks and frames — are extremely durable.  However, excessive jumping on the planks can cause damage to both the planks and the frames. Frames are also damaged if the bleachers are moved. Other areas of concern can be the hardware connections, footings, and any steel components that were not properly galvanized or coated.

Do we need an architect and/or engineer for a telescopic bleacher, angle frame bleacher, or grandstand project?

All competent bleacher and grandstand manufacturers are capable of providing engineer stamped drawings.  With grandstands, it is nearly mandatory, with the exception being when the owners structural engineer becomes engineer of record (EOR).  However, on nearly all projects, the grandstand manufacture's engineer is the EOR and is responsible for foundation and grandstand engineering. Depending on the jurisdiction, angle frame bleachers and telescopic bleachers are treated somewhat different.  With angle frame bleachers, it is less definitive, as small 3 row, 5 row, and 10 row bleachers are often considered standard "pre-engineered" products and are sold without engineer stamped drawings and installed without a building permit.  However, many building departments consider all bleachers to be structures and therefore require a building permit.   Please check with the local authorities regarding whether a permit is required.  Telescopic bleachers are also often treated similar to angle frame bleachers as much of the structure is standard and "pre-engineered.  Again some building departments are more stringent than others and do require building permit for all bleacher projects, no matter the size. If the project does require a building permit it is likely to require an architectural review in addition to the structural engineer's stamped drawings and structural calculations.   The architectural review is all about code compliance,  which will always include seating and aisle layout, egress requirements, and ADA accommodations. However, a complete  architectural review includes number of toilets, distance to toilets, ADA routes, ADA parking, and more.   Most manufacturer's will only provide the code compliant bleachers, however some are willing to manufacture bleachers that do not meet all codes.  Since the manufactures' do not have access to all of the information often required for an architectural review, they do not typically provide that service.  However, if the purchase takes place through a local dealer, the local dealer may have the ability to provide the architectural review through a subcontracted qualified architect. If there are concession or storage buildings included with the project, an architect for the entire project is highly recommended.
