FAQ

SSE provides project evaluation, cost estimating, technical and shop drawing preparation, system manufacturing, coordination and logistics, job site delivery, and project management.

SSE is headquartered in Southern California and we provide all design and management services from our Southern California headquarters. PREFOAM Stadium Seating Riser Systems and PREFOAM EPS Geofoam Systems are manufactured within six regional hubs with more than 40 manufacturing partners. This business model ensures responsive, cost efficient manufacturing and distribution of our projects.

SSE does not directly employ installation crews. However, over the years we have developed relationships with experienced concrete subcontractors and independent installation crews. We would be happy to address the need for installation services on a case-by-case basis.

No. SSE does not have in-house structural engineering and it is not typically required as part of the PREFOAM Stadium Seating Riser Systems. However, we have relationships with experienced structural engineers throughout North American and can, in many cases, provide a recommendation for a third party structural engineer with prior PREFOAM Stadium Seating Riser System experience if required.

PREFOAM EPS Geofoam is manufactured as a 48’W x 36”H x 16’L block. Typically PREFOAM EPS Geofoam blocks are shipped to the jobsite in lengths no longer than 96” for ease of handling. PREFOAM EPS Geofoam blocks can be provided at any height from 2” – 36” and can also easily be pre-cut at a predetermined slope (angle) in any single direction.

PREFOAM EPS Geofoam 15 weighs approximately 1#/Cu. Ft. A pre-cut 48” x 36”H x 96”L PREFOAM Geofoam block is 96 cubic feet and weighs approximately 96 pounds.

No, the PREFOAM Stadium Seating Riser Systems can be designed to accommodate virtually any riser height or platform depth.

Structural steel framing is typically utilized for the construction of the occupied space prior to delivery of the PREFOAM Stadium Seating Riser System. Traditionally, the structural engineer will incorporate a structural deck above the occupied space which will serve as one platform for the tiered seating. PREFOAM EPS Geofoam blocks are then stacked on the structural deck to construct additional tiers of stadium seating above the occupied space below.

Yes, the PREFOAM Stadium Seating Riser System can easily accommodate riser mounted seating with the addition of a four inch vertical channel of concrete behind the risers to accept the mounting hardware needed for riser mount seating.

PREFOAM EPS Geofoam blocks are typically only cut to accommodate a slope in one direction. However, there are other options that can be used to accommodate a compound slope on the existing slab.

No, unique ONLY to the PREFOAM Stadium Seating Riser System, all steel components are prefabricated to accommodate the specific dimensions of the tiered seating layout without the need for contractor field cutting.

Typically the overall cost of the PREFOAM Stadium Seating Riser System will be approximately 15-25% less than the cost of the steel system.

The installation contractor should be able to install the PREFOAM EPS Geofoam blocks and Steel System including intermediate steps in no more than 1 ½ days with a four man crew.

No, in fact, during a recent church project in the North Eastern US, the parishioners participated in the installation of the PREFOAM Stadium Seating Riser System. On that project, at the end of the construction, the church reported a savings of more than $65,000.00 in costs due to the use of unskilled and/or volunteer labor.
