Proposal for Initial Annual Inspection: Illinois State Fair Multipurpose Arena Grandstand Tensile Canopy Structure

This document is to serve as our formal proposal for an annual system inspection for the Tensile Membrane Structures re-designed, fabricated, and re-built by Span Systems Inc.

Experience of over 30 years of specialty contracting in this field has shown that a regular inspection program is necessary to insure optimal structural performance over time. It is particularly important to properly maintain a structure like the one at ISF, where the fabric system is predominantly stabilized by cable components at the membrane perimeter, allowing for greater movement within the fabric field.

A formal annual inspection provides the opportunity to:

Check and correct any deviation or fabric “creep” from the designed fabric pre-stress requirements. This is particularly important after the first year of loading as this is when the fabric would exhibit the largest potential relaxation.

Heat seal, repair or reinforce any minor fabric penetrations.

Check for potential problems, areas of wear or other system degradation.

We believe this is critical to maximize the lifespan of the fabric envelope and to repair small potential issues before they become larger.

NOTE: The formal annual inspection is not a substitute for regular and typical local visual inspection for any issues that might crop up. This is essential to ensure that any more obvious damage that may occur, especially after stormy weather, is noted, photographed, and reported. Span Systems can determine what immediate action may need to occur to prevent a small area of damage from propagating into a larger issue.

This inspection requires mobile aerial lifts to access all parts of the structures and will need to be scheduled so as not to interfere with the users of these outdoor areas.

This inspection will include the tensile canopy system and all related components installed at the Multi-Purpose Arena Grandstand.

• Visually inspect fabric envelope for tension.

• Ensure membrane is not abrading or contacting foreign materials.

• Check tightness of all turnbuckles, shackle pins, cotter keys, tensioning rods, and elements.

• Evaluate fabric edges for fraying.

• Check Catenary pockets and cover flaps for proper adhesion.

• Ensure cable covers are intact.

• Ensure no cables are slack or abrading the fabric membrane.

• Inspect all clamping plates for tightness of fasteners.

• Inspect rope beads for proper position and to ensure bead has not pulled out or torn.

• Evaluate overall condition of fabric envelope including any unusual areas of discoloration, debris or bird dropping contamination.

• Inspect the fabric panels for any observed loss of prestress or tension.

• Tension testing at multiple locations on each structure and retension if necessary.

• Inspect the fabric for punctures or areas or abnormal wear or abrasion.

• Minor patching included is defined as small holes or tears less than 4” x 4” and non-specific source that may be construed as normal wear and tear, large tears may be repaired during annual visit but with an additional labor cost plus material and equipment.

• Formal report of structure’s condition and recommendations.

Typically, an inspection/re-tensioning is recommended no more than 12 months after completion of installation and imparting of design pre-stress loads to account for some expected ‘creep’ during the first year after installation. Subsequently inspections can be scheduled every 12 – 18 months depending on systems performance, weather conditions, etc.

However local facilities personnel should make it a policy to visually check for issues on a regular daily/weekly/monthly basis so that any new issue that may emerge can be assessed and responded to quickly.

INSPECTION COST:

Inspection: $ 19,000.00

Tel (603) 621-4090 Fax (603) 782-8476 www.spansystemsinc.com

Please note that this price includes prevailing union wages in the area. Should it be acceptable to use our full-time non-union erection crew the price can be adjusted upon request. This price is for the first inspection anticipated to be performed 1-year from substantial completion and includes rental of an extra-high-reach lift and tools and personnel to reach the peak cones to make any adjustments needed. This proposal will be adjusted for inspections performed after the first inspection outlined herein and will not exceed that cost.

WARRANTY CLAIMS

Your structure has been warranted to be free from material defects in components and workmanship for a period as specified in the contract documents. Your structure may be governed by differing warranty terms depending upon the specifications. Please consult your warranty terms depending upon the specification. Repairs and maintenance procedures performed by anyone other than Span Systems authorized personnel are not covered under your warranty. Please consult your warranty form for specific information concerning your warranty rights. ON-GOING MAINTENANCE IS THE RESPONSIBILITY OF THE OWNER AND IS NOT

COVERED BY YOUR WARRANTY.
