Stage Pre Start /Site clearance
Applicable B. Regs
Preparation of site. C1 The bottom to be included in a building shall be reasonably free from vegetable matter.
Dangerous substances. C3 Sensible precautions will be taken to avoid threat to health and safety triggered by substances (including contaminants) found on or in the bottom to be included in a building.
"Contaminant" includes any product which is or could become flammable, explosive, corrosive, toxic or radioactive and any debris of faecal or canine matter;
D1 "All works to which to which these Rules apply shall be completed with proper materials and in a workmanlike manner"
B. Regs Compliance
Soil investigation carried out with assessment for possible garden soil contamination
TGD C 2. 2 In every cases, appropriate site investigations should be carried out to check on for the occurrence of contaminants. Contaminants may arise from options outside of the site e. g. landfill (see par. 2. 18).
Ground Clearance/ Removal of deleterious materials
Table 1 TGD C Sites more likely to contain contaminants
Gas works, coal carbonisation vegetation and ancillary by-product works
Industries making or using hardwood preservatives
Landfill and other waste disposal sites or ground within 250 metres of such sites
Metal mines, smelters, foundries, metallic works and metal finishing works
Oil storage area and circulation sites
Paper and printing works
Railway land, especially the bigger sidings and depots
Sewage works, sewage farms and sludge disposal sites
Table 2 Possible contaminants
Signs of possible contaminant
(a) Vegetation (absence of, metals, metal chemical substances, poor or unnatural expansion) organic materials, gases
(b) Surface materials (unusual metals, metallic compounds, oily colors and contours may and tarry wastes, asbestos (loose), indicate wastes and other fibres, organic and natural compounds residues) (including phenols), possibly combustible material including coal and coke particles, refuse and waste
(c) Fumes and odours (may flammable, explosive and indicate organic chemicals asphyxiating gases, including at very low methane and skin tightening and, concentrations) corrosive liquids, faecal, creature and vegetable subject (biologically dynamic)
(d) Drums and containers various (whether full or unfilled)
TGD C 2. 5 If the occurrence of pollutants is established, appropriate remedial action should be performed and, except regarding Radon, (see par. 2. 7), and the neighborhood specialist should be educated.
TGD C 2. 6 Where the most hazardous conditions arise, only the total removal of pollutants can provide an entire treatment. In other conditions, alternative procedures may decrease the risks to acceptable levels. Where there is a risk of gas accumulating, appropriate procedures must be studied in the look and structure of the building. In every instances, action should only be performed with the good thing about expert advice.
Compliance with HSA procedures
ADDITIONAL Records REQUIRED
Resolution removal by insured operatives (many contractors insurances do not include asbestos) to licenced facility with certificates
TGD C 1. 3 Turf and other vegetable subject should be removed from the ground to be covered by the building at least to a depth sufficient to prevent later growth.
TGD C 1. 4 Where the ground to be covered by the building includes tree root base or immediately compressible materials (even if it includes no organic material) that could affect the steadiness of the building, building services (such as below surface drainage) should be sufficiently robust or versatile to withstand or accommodate motion. Joints should be made so that root base won't penetrate them.
Health & Safety
Read preliminary H & S File regarding risks on existing site including
Surface drinking water drainage
Are live services safely terminated?
Are secure site restrictions set up?
LIST IS Primary, IS INDICATIVE ONLY AND NEEDS WORK
Non B Regs. / H&S
Are legal boundaries settled and clear?
Are the position of boundary walls clear/ who owns them?
Are the walls get together walls?
Has a conditions review of adjoining properties, roads, footpaths been undertaken
Have easements and wayleaves been proven e. g. access to ESB sub-station
Preliminary only. Will be in spreadsheet format
