The Steel Testing Program shall include but may not be limited to cutting steel coupons from the existing structure, measurement of physical properties, patching/repair of existing structural steel element where the coupon was extracted, and shipping and handling for testing. Record of the physical properties (steel gauge) to be coordinated with the Consultant on site while the chemical composition and steel grade to be shipped to a laboratory for testing. A recommended laboratory for testing is SGS Canada Inc.

.4 Contractor is to coordinate to send coupons to an approved laboratory and pay for all laboratory testing.
.5 All steel samples are to be tested for steel tensile strength per ASTM and thickness measurements. One (1) sample per building is to be tested for chemical analysis and steel grade determination.
.6 The Contractor will provide all materials, tools, equipment, labour, and items of a consumable nature as required to execute the work including but may not be limited to dust and fume control for welding on site.
.7 Contractor to provide scissor lift and operator required to complete visual structural review and to take field measurements of structure (width, height, length, radius).
.8 The Contractor shall be responsible for coordinating and paying for any and all access requirements to complete their work.
.9 Contractor is to coordinate with the Owner and submit all work permit and maintain site security clearances as required.
