The client and contractor should refer to the comprehensive TechSpan® construction manual for a complete list of equipment, tools and miscellaneous items recommended to be used to aid the installation of the TechSpan® arches. In summary,

RECO supplies the following:

• design and certification of the precast concrete TechSpan® arch;
• manufacture and supply of the TechSpan® arch elements;
• supply of vertical and longitudinal impermeable jointing material;
• delivery of construction materials to the job-site FOT (free on truck);
• on-site technical advice and guidance.

The contractor is responsible for installation of the arch, and supplying the recommended equipment for arch element lifting, earth backfilling and compaction.

Unloading and storage of components

TechSpan® arch elements are transported on flatbed trailers to site. It is preferable that arch elements should be unloaded from the truck and erected immediately.

Where necessary, elements may be placed in a separate storage area for erection at a later date.
Using the correct lifting clutches to suit the anchor size cast into the top edge, elements should be carefully removed from the delivery vehicle and placed on edge on proper hardwood dunnage (two supports only) on firm level ground. Care must be taken to protect the elements from damage or distortion during handling and storage. Improper support will result in structural damage.
