Dave, not sure what your question means but let me have a bash at some of it.
Difficulties in relation to existing plant and equipment:
- in your plan there should be a list of all the construction/lifting equipment that is planned to be used. Whether owned or hired, ensure they comply with LOLER regs where applicable, with statutory exam documents, that includes any harnesses and accessories, FLTs, telehandlers etc.
- all operators of vehicles and lifting trucks hoists etc should have documented training
Significant and principal risks identified during design:
- getting materials to where they are needed e.g. steel, glazing, large items etc
- handling other special construction materials
- design/plan of the scaffolding, e.g. how will it be tied
- if refurbishment, asbestos management
- fire safety. Fire Risk Assessment, and know at what times it needs revision e.g. when there are staircases installed, roof is on, windows installed, how many accessible exits, assembly point, klaxons, is there a Fire Marshall
- Traffic management/map required, pedestrian entrance/exits, routes for dumper trucks, telehandlers etc.
- define location for block cutting which creates dust and noise.
- etc
Materials requiring particular precautions:
- cement, need a COSHH assessment, provide PPE, training or toolbox talks
- flammable materials and equipment e.g. plumber torches, paint, solvents, sealants, and storage of.
