Steelwork Sample Clauses
The Steelwork clause defines the requirements and standards for all steel components used in a construction project. It typically outlines specifications for materials, fabrication, installation, and protective treatments such as painting or galvanizing, and may reference relevant industry codes or standards. By clearly setting out these expectations, the clause ensures that all steelwork meets safety, durability, and quality requirements, thereby minimizing the risk of structural failure and disputes over workmanship.
Steelwork. 2.12.3.1 Structural steelwork, except for weathering resistant steels, shall be protected using a paint system appropriate to an ‘Inland’ environment and ‘Difficult’ access in accordance with Series 1900 of the Specification and shall meet the following minimum durability requirements:
a) no maintenance up to 12 years b) minor maintenance from 12 years c) major maintenance after 20 years.
2.12.3.2 The Company’s proposed paint systems, including completed Specification Appendices shall be submitted to the Transport Scotland (Bridges Branch) prior to execution of any relevant part of the New Works. The Company shall not commence any painting Works before such consultation has taken place and the paint system and colour is approved by Transport Scotland (Bridges Branch). The Company shall provide the Scottish Ministers with the completed Consultation Certificate in accordance with Section 8 of PART 5 of these New Works Requirements.
2.12.3.3 All paint systems shall comply with the requirements of current Environmental and Health & Safety regulations and legislation.
2.12.3.4 The use of weathering steel shall be permitted.
2.12.3.5 Intermittent fillet welds shall not be permitted outwith areas that are completely protected from the adverse effects of weather.
2.12.3.6 The design of steelwork shall ensure the prevention of the accumulation of water, dirt and debris.
2.12.3.7 Exposed structural steelwork shall not be used in the substructures of Structures.
2.12.3.8 Where the design of the New Works includes transition slabs, stainless steel reinforcement, grade 1.4436 or 1.4462 to BS EN 10088 shall be used in connecting a transition slab to an abutment.
2.12.3.9 Transition slabs shall be treated as part of the superstructure with regard to application of the waterproofing system and the provision of either articulation or movement joints.
2.12.3.10 Reinforcement bridging joints, or items penetrating the concrete surface, and also subject to chloride contamination (e.g. dowel bars) shall be stainless steel Grade 1.4436 or 1.4462.
2.12.3.11 Any mechanical bearings, where permitted, shall be either steel with protection of steelwork against corrosion, or stainless steel, with the following minimum grades:
a) plates and flats shall be 1.4436 or 1.4462;
b) sliding surfaces shall be 1.4436 or 1.4462; and
c) fasteners shall have mechanical properties and dimensions that comply with grade A4-70 or A5-80. Chemical composition shall comply with grade 1.4436 or 1.4462.
