A33 Quality Standards/Control
Checklist:

Problem:

• Materials and products are often surreptitiously substituted by the contractor or sub-contractor between tendering and delivering to site

---

Misunderstanding:

• The use of ‘Or Equivalent’ in a specification after a product reference is not an invitation to substitute any ‘or similar’ product, it must have equivalent properties and the Contract Administrators should police it.

---

Solution:

• Check all delivery tickets, product labels and packaging to ensure it is as specified or an equivalent that has been reviewed by the specifier.
• Do frequent checks during the project to ensure a switch has not occurred during the works

---

Consider:

• Provide adequate temporary roads and storage space and level/well drained hard standing for materials.
• Any excess concrete from large pours, can be used to make another meter of site access road or storage areas.
• Consider lime stabilisation of moist or wet subsoil if concrete roads and hard standing are not planned.
• Provide weather-tight enclosures to protect materials from rain, snow, mist, fog, etc.
• Provide temperature and humidity controlled enclosures for storage of vulnerable materials.
• Provide these before any materials are delivered to site.
• Ensure all materials and waste storage areas are accessible by appropriate vehicles.

---

Avoid:

• Collapsed pallet stacks on sloping site
• Materials delivered without pallets: example: Bricks: bottom layer of materials sit in the mud then get put into the skip and then off to landfill.
• Materials spoiled by change in moisture content or storage humidity and temperature
• Materials splashed by mud and cement/concrete slurry

---

Value Engineering: (Posh for cost cutting)

• Don’t be tempted to permit a substitution away from ‘Proper Materials’ (e.g. Kitemarked, BBA, ETA certified)
• ‘Proper Materials’ have a longer life expectancy than products which are not made to nor tested against a standard specification.
• ‘Proper Materials’ consistently demonstrate a longer life expectancy and insurable life
