Appendix A Definition of geotechnical terms

Report: STM3210B-G01 of 2 Appendix A

Definition of geotechnical terms used in this report - foundations Strip foundations. A foundation providing a continuous longitudinal ground bearing. Trench fill concrete foundation. A trench filled with mass concrete providing continuous longitudinal ground bearing. Pad foundation. An isolated foundation to spread a concentrated load. Raft foundation. A foundation continuous in two directions, usually covering an area equal to or greater than the base area of the structure. Substructure. That part of any structure (including building, road, runway or earthwork) which is below natural or artificial ground level. In a bridge this includes piers and abutments (and wing walls), whether below ground level or not, which support the superstructure. Piled foundations and end bearing piles. A pile driven or formed in the ground for transmitting the weight of a structure to the soil by the resistance developed at the pile point or base and the friction along its surface. If the pile supports the load mainly by the resistance developed at its point or base, it is referred to as an end-bearing pile; if mainly by friction along its surface, as a friction pile. Bored cast in place pile. A pile formed with or without a casing by excavating or boring a hole in the ground and subsequently filling it with plain or reinforced concrete. Driven pile. A pile driven into the ground by the blows of a hammer or a vibrator. Precast pile. A reinforced or prestressed concrete pile cast before driving. Driven cast in place pile. A pile installed by driving a permanent or temporary casing, and filling the hole so formed with plan or reinforced concrete. Displacement piles. Piled formed by displacement of the soil or ground through which they are driven. Skin friction. The frictional resistance of the surrounding soil on the surface of cofferdam or caisson walls, and pile shafts. Downdrag or negative skin friction. A downwards frictional force applied to the shaft of a pile caused by the consolidation of compressible strata, e.g. under recently placed fill. Downdrag has the effect of adding load to the pile and reducing the factor of safety.

Appendix A Definition of geotechnical terms

Report: STM3210B-G01 of 2 Appendix A

Definition of geotechnical terms used in this report – bearing values Ultimate bearing capacity. The value of the gross loading intensity for a particular foundation at which the resistance of the soil to displacement of the foundation is fully mobilised. Presumed bearing value. The net loading intensity considered appropriate to the particular type of ground for preliminary design purposes. The particular value is based on calculation from shear strength tests or other field tests incorporating a factor of safety against shear failure. Allowable bearing pressure. The maximum allowable net loading intensity at the base of the foundation, taking into account the ultimate bearing capacity, the amount and kind of settlement expected and our estimate of ability of the structure to accommodate this settlement. Factor of safety. The ratio of the ultimate bearing capacity to the intensity of the applied bearing pressure or the ratio of the ultimate load to the applied load.

Definition of geotechnical terms used in this report – road pavements The following definitions are based on Transport and Road Research Laboratory (TRRL) Report LR1132. Equilibrium CBR values. A prediction of the CBR value, which will be attained under the completed pavement. Thin pavement. A thin pavement (which includes both bound and unbound pavement construction materials 1 in 300mm thick and a thick pavement is 1200mm thick (typical of motorway construction).

Appendix B Geo-environmental terms and bibliography

Report: STM3210B-G01 Page 1 of 5 Appendix B

Definition of geo-environmental terms used in this report Conceptual model Textual and/or schematic hypothesis of the nature and sources of contamination, potential migration pathways (including description of the ground and groundwater) and potential receptors, developed on the basis of the information obtained from the investigatory process. Contamination Presence of a substance which is in, on or under land, and which has the potential to cause harm or to cause pollution of controlled water. Controlled water Inland freshwater (any lake, pond or watercourse above the freshwater limit), water contained in underground strata and any coastal water between the limit of highest tide or the freshwater line to the three mile limit of territorial waters. Harm Adverse effect on the health of living organisms, or other interference with ecological systems of which they form part, and, in the case of humans, including property. Pathway Mechanism or route by which a contaminant comes into contact with, or otherwise affects, a receptor. Receptor Persons, living organisms, ecological systems, controlled waters, atmosphere, structures and utilities that could be adversely affected by the contaminant(s). Risk Probability of the occurrence of, and magnitude of the consequences of, an unwanted adverse effect on a receptor. Risk Assessment Process of establishing, to the extent possible, the existence, nature and significance of risk.



Definition of environmental risk/hazard terms used in this report.

Based on CIRIA report C552 ‘Contaminated land risk assessment – A guide to good practice’.

Potential hazard severity definition

Category

Definition

Severe Acute risks to human health, catastrophic damage to buildings/property, major pollution of controlled waters

Medium Chronic risk to human health, pollution of sensitive controlled waters, significant effects on sensitive ecosystems or species, significant damage to buildings or structures.

Mild Pollution of non sensitive waters, minor damage to buildings or structures.

Minor Requirement for protective equipment during site works to mitigate health effects, damage to non sensitive ecosystems or species.

Probability of risk definition

Category

Definition

High likelihood Pollutant linkage may be present, and risk is almost certain to occur in long term, or there is evidence of harm to the receptor.

Likely Pollutant linkage may be present, and it is probable that the risk will occur over the long term

Low likelihood Pollutant linkage may be present, and there is a possibility of the risk occurring, although there is no certainty that it will do so.

Unlikely Pollutant linkage may be present, but the circumstances under which harm would occur are improbable.

Definition of environmental risk/hazard terms used in this report.

Based on CIRIA report C552 ‘Contaminated land risk assessment – A guide to good practice’.

Risk classifications and likely action required:

Very high risk High probability that severe harm could arise to a designated receptor from an identified hazard OR there is evidence that severe harm to a designated receptor is currently happening. This risk, if realised is likely to result in substantial liability. Urgent investigation and remediation are likely to be required. High risk Harm is likely to arise to a designated receptor from an identified hazard. This risk, if realised, is likely to result in substantial liability. Urgent investigation is required and remedial works may be necessary in the short term and are likely over the long term. Moderate risk It is possible that harm could arise to a designated receptor from an identified hazard. However, it is either relatively unlikely that any such harm would be severe, or if any harm were to occur it is likely that the harm would be relatively mild. Investigation is normally required to clarify risks and to determine potential liability. Some remedial works may be required in the long term. Low risk It is possible that harm could arise to a designated receptor from an identified hazard but it is likely that this harm, if realised, would at worst normally be mild. Very low risk It is a low possibility that harm could arise to a designated receptor. On the event of such harm being realised it is not likely to be severe.



Gaseous contamination - Extract copy of table 3 of BS8485:2007 Solutions scores

PROTECTION ELEMENT/SYSTEM SCORE COMMENTS

a) Venting/dilution (see Annex A of BS8485)

Passive sub-floor ventilation (venting layer can be a clear void or formed using gravel, geocomposites, polystyrene void formers, etc) A)

Very good performance

2.5 Ventilation performance in accordance with Annex A of BS8485.

Good performance

1

If passive ventilation is poor this is generally unacceptable and some form of active system will be required.

Subfloor ventilation with active abstraction/pressurization (venting layers can be a clear void or formed using gravel, geocomposites, polystyrene void formers, etc)A)

2.5

There have to be robust management systems in place to ensure the continued maintenance of any ventilation system.

Active ventilation can always be designed to meet good performance.

Mechanically assisted systems come in two main forms: extraction and positive pressurization

Ventilated car park (basement or undercroft) 4 Assume car park is vented to deal with car exhaust fumes, designed to Building Regulations Document F and IStructE guidance.

b) Barriers

Floor Slabs It is good practice to install ventilation in all foundation systems to effect pressure relief as a minimum.

Block and beam floor slab 0

Reinforced concrete ground bearing floor slab 0.5

Reinforced concrete ground bearing foundation raft with limited service penetrations that are cast into slab

1.5 Breaches in floor slabs such as joints have to be effectively sealed against gas ingress in order to maintain these performances.

Reinforced concrete cast in situ suspended slab with minimal service penetrations and water bars around all slab penetrations and at joints

1.5

Fully tanked basement 2

c) Membranes

Taped and sealed membrane to reasonable levels of workmanship/in line with current good practice with validation B), C)

0.5 The performance of membranes is heavily dependent on the quality and design of the installation, resistance to damage after installations, and the integrity of joints. Proprietary gas resistant membrane to reasonable levels of workmanship/in line

with current good practice under independent inspection (CQA) B), C) 1

Proprietary gas resistant membrane installed to reasonable levels of workmanship/in line with current good practice under CQA with integrity testing and independent validation.

2

d) Monitoring and detection (not applicable to non-managed property, or in isolation)

Intermittent monitoring using hand held equipment 0.5 Where fitted, permanent monitoring system ought to be installed in the underfloor venting/dilution system in the first instance but can also be provided within the occupied space as a fail safe.

Permanent monitoring and alarm system A) Installed in the underfloor venting/dilution system

2

Installed in the building 1

e) Pathway Intervention

Pathway intervention - This can consist of site protection measures for off-site or on-site sources (see Annex A of BS8485)

NOTE In practice the choice of materials might well rely on factors such as construction method and the risk of damage after installation. It is important to ensure that the chosen combination gives an appropriate level of protection. A) It is possible to test ventilation systems by installing monitoring probes for post installation validation.

B) If a 200g DPM material is to function as a gas barrier it should be installed according to BRE 212)/BRE 414), being taped and sealed to all penetrations.

C) Polymeric Materials > 1 200g can be used to improve confidence in the barrier. Remember that their gas resistance is little more than the standard 1 200g (proportional to thickness) but their physical properties mean that they are more robust and resistant to site damage.

5. The Contractor shall take particular care in relation to the protection of Company Apparatus, where such

Apparatus includes the presence within the site of optical fibre cabling. The contractor should particularly note that the damage to such Apparatus is extremely disruptive to the Company network and costly to reinstate. The Contractor shall make every effort to avoid the disturbance of Company Apparatus more than is absolutely necessary for the completion of the works in accordance with the contract.

CIV/005/02 2

6. When excavating around, moving or backfilling around Company Apparatus, the Company Representative

shall be given adequate notice, which shall not be less than 3 days, of the contractor’s intentions in order that he may supervise the works. The Contractor should note that the normal depth of cover for Company Apparatus and ducts are as follows: -

a. Carriageways 600mm

b. Footways 350mm

c. Verges 450mm

These minimum depths of cover should be maintained wherever possible. Where the minimum depths of cover cannot be maintained, the Contractor shall carry out the instructions of the Company Representative for the protection of Company Apparatus. Where cables are not in duct and the required depth of cover cannot be maintained, such cables as are affected shall be enclosed and protected in UPVC duct or equivalent materials as supplied by the Company and by the method directed by the Company Representative. With regard to excavation in the vicinity of Company Apparatus the Contractor should have particular regard to the possibility of reduced cover and the encountering of such Company Apparatus at depths of cover less than that given at a, b and c above.

7. All excavation adjacent to Company Apparatus is to be carried out by hand until the exact extent and/or

location of Company Apparatus is known. Mechanical borers and/or excavators shall not be used within 1.0m of Company Apparatus without the supervisory presence of a Company Representative, To prevent any movement of Company Apparatus during excavations, complete shuttering shall be used as directed by the Company Representative if:-

a. Excavation is deeper than the depth of cover of adjacent Company Apparatus.

b. Excavation is within 1.0m of Company Apparatus in stable ground.

c. Excavation is within 5.0m of Company Apparatus in unstable ground.

If for the completion of the works, the Contractor intends using any of the following: -

a. Pile driving equipment within 10.0m of Company Apparatus.

b. Explosives within 20.0m of Company Apparatus.

c. Laser equipment within 10.0m of Company Apparatus.

The Contractor shall advise the Company Representative, giving at least 7 working days written notice in order that any special protective measure for the Company Apparatus affected may be arranged.

8. All Company manhole, joint box and /or other access points and chambers within the site shall be kept clear and unobstructed. Access for vehicles, winches, cable drums and/or further equipment required by the Company for the maintenance of it’s Apparatus, must be maintained at all reasonable times. The Contractor should particularly note that footway type jointing chambers are not specified for carriageway loadings and will need to be adequately protected and/or demolished and rebuilt under the supervision of a Company Representative where such chambers are likely to be placed at risk, either temporarily or permanently, from the movement of plant and/or equipment on the site.

CIV/005/02 3

9. The covers to Company chambers and/or Apparatus shall only be lifted by means of appropriate keys

obtained from the Company Representative and under the direct supervision of the Company Representative. No employee of the Contractor or of any sub-contractor employed by the Contractor shall enter any chamber and/or Apparatus of the Company unless under the supervision of the Company Representative and in any case not before the mandatory gas check has been carried out in the presence of the Company Representative and such checks have shown it to be safe to enter the chamber and/or Apparatus of the Company. The Company Representatives shall be given reasonable access to all Company Apparatus and chambers when required.

10. In the event of any damage whatsoever to Company Apparatus, the Contractor shall immediately inform

the Company Representative and report the occurrence immediately by contacting the Company as follows:-

Telephone:-

0208 731 4600 Mon-Fri Office Hours (Instalcom Head Office)

0208 510 3111/3101 Out of Office Hours (24Hr Level 3 Network Operations Centre)

Dear Sir / Madam

An Asset Location Search is recommended when undertaking a site development.It is

essential to obtain information on the size and location of clean water and sewerage assets

to safeguard against expensive damage and allow cost-effective service design.

The following records were searched in compiling this report: - the map of public sewers &

the map of waterworks. Thames Water Utilities Ltd (TWUL) holds all of these.

This searchprovides maps showing the position, size of Thames Water assets close to the

proposed development and also manhole cover and invert levels, where available.

Please note that none of the charges made for this report relate to the provision of Ordnance

Survey mapping information. The replies contained in this letter are given following

inspection of the public service records available to this company. No responsibility can be

accepted for any error or omission in the replies.

You should be aware that the information contained on these plans is current only on the day

that the plans are issued. The plans should only be used for the duration of the work that is

being carried out at the present time. Under no circumstances should this data be copied or

transmitted to parties other than those for whom the current work is being carried out.

Thames Water do update these service plans on a regular basis and failure to observe the

above conditions could lead to damage arising to new or diverted services at a later date.

Please provide a copy extract from the public sewer map.

Enclosed is a map showing the approximate lines of our sewers. Our plans do not show sewer connections from individual properties or any sewers not owned by Thames Water unless specifically annotated otherwise. Records such as "private" pipework are in some cases available from the Building Control Department of the relevant Local Authority. Where the Local Authority does not hold such plans it might be advisable to consult the property deeds for the site or contact neighbouring landowners. This report relates only to sewerage apparatus of Thames Water Utilities Ltd, it does not disclose details of cables and or communications equipment that may be running through or around such apparatus. The sewer level information contained in this response represents all of the level data available in our existing records. Should you require any further Information, please refer to the relevant section within the 'Further Contacts' page found later in this document. For your guidance:

• The Company is not generally responsible for rivers, watercourses, ponds, culverts

or highway drains. If any of these are shown on the copy extract they are shown for

information only.

• Any private sewers or lateral drains which are indicated on the extract of the public

sewer map as being subject to an agreement under Section 104 of the Water

Industry Act 1991 are not an ‘as constructed’ record. It is recommended these

details be checked with the developer.

Clean Water Services
