Tata Steel Projects - the foundations of project successTata Steel Projects has a dedicated Geotechnical Design Team with considerable experience in deliveringEurocode compliant solutions to clients with differing needs and requirements. We work across a broad rangeof market sectors within the UK including the Energy and Power sector, Transportation (Rail & HighwaysInfrastructure) and the Nuclear sector. Our team understands the importance of addressing our clientsrequirements and their construction risks. We manage the process from concept to numerical modellingthrough to construction design and support.

Earthworks and Slope Stability

ComplianceThere is a high level of risk attached to the

construction and management of new and

historic slopes. Slope failures are a safetycritical issue and have the potential to

result in serious injury or even death. They

can also cause significant infrastructure

damage and result in major delays during

construction and disruption on operationalsites.

We have considerable experience in the

design and construction of new reservoir

and highway slopes and earth bunds. Wehave also worked extensively with Network

Rail on the management of historic slopes

on their infrastructure. We offer the

following design and construction supportservices:

Walkover assessments of historical

slopes and slip features (includingbio-engineering and influence

of vegetation) to Network Rail

standards

Slope stability design for existing

slopes and compliance withEurocode 7 and clients technical

remit

Design and earthworks specificationfor re-grade solutions

Design and specification for gravity

wall solutions (where boundary

constraints exist)

Design and specification of soil nail/facing solutions

Deep Excavations and Earth

Retaining StructuresDeep Excavation support or earth retaining

wall structures are often required for larger

construction projects or schemes withinurban areas.

Deep excavations have significant risk in

both temporary (during construction) and

permanent conditions and also whereconstruction below the water table is

expected. We offer the following support

services to de-risk your projects:

Economised secant and contiguouspile wall design through iterative

design approaches

Diaphragm wall design

Sheet pile wall design (includingdriveability studies where required)

King post wall design

Reinforced concrete gravity wall

design (gabions and reinforced earthstructures)

Soil nail and sprayed concrete wall

design options

Dewatering assessments and cut off

studies to assess impact on watertable and surrounding contaminant

mobility

Detailed specification and monitoringstudies

Temporary propping designs and

impact on wall movements

Permanent and temporary ground

anchor systems (both pre-stressedand passive systems) using bar or

strand

Shallow Foundation and

Ground Improvement DesignShallow Foundation and Ground

Improvement Design can negate the needfor piled solutions that are not only costly

but also cause risk to protected aquifers and

risk creating contaminated spoil.

The key to these solutions is accurate

load and geophysical testing methods of

ground stiffness on sites to give all parties

confidence in load settlement predictions.

We offer the following foundationand ground improvement design and

construction support services:

Shallow foundation settlementanalysis and site testing (including

static and geophysical methods of

stiffness evaluation)

Ground bearing slab design

(including settlement profiles andstructural analysis support)

Soil mixing techniques (column and

mass stabilisation) within highly

compressible soils

Vibro-stone columns, vibro-concrete

columns including load transfer

platform design

Surcharge loading and dynamic

compaction of soils Grouting works e.g. rock, fissure,

permeation and compaction

grouting

Trackbed and highway formationdesign including shallow soil mixing

to minimise formation design

thicknesses

Reinforced Concrete

Bearing Pile and Micropile

Underpinning WorksThe key to this service is understanding the

pile types, design performance and risks

with regard to obstructions on the sites.

Our capabilities, coupled with our strong

links to the specialist piling industry allow

us to optimise on the specific pile type and

diameter for any site.

Our pile design and construction support

is linked to a firm understanding of pile

construction type, achievable loads(horizontal, compression and tension) in

ground conditions expected and efficient

pile group analysis.

Where piling is required for new build (or

to underpin existing failing structures), we

offer a design and construction support

service:

Reinforced concrete CFA and Bored

Pile Design

Detailing of static and dynamic

testing methods to optimise design

solutions (Eurocode 7 compliant)

Micropile design and construction

methods to deal with problemground and underpin structures

Pile group analysis optimising pile

layout and performance

Design for laterally loaded piles (both

free headed and with fixity)

Design of driven steel tubular

systems (including driveability

studies to assess installation risks)

Driven Steel Piling Solutions for

the Railway IndustryAs part of the organisations strong link to

railway and electrification design, we offer a

full design and construction support service

for electrification structures.

These structures are unusual in that they

are located on unstable embankments

and support predominantly lateral loads

with small vertical loading. We have been

involved in design and construct solutions

for an number of years and have a strong

understanding of pile sizes and installation

risks for all types of electrificationequipment.

To support construction works, we offer the

following services:

Targeted investigation and ground

modelling to optimise risks and

solutions

Side bearing concrete foundation

design

Gravity pad foundation design

(including stability and settlement

analysis)

Steel tubular pile design in regard

stability and pile head deflections

Driveability studies for tubular pilesusing vibrating and impact hammers

Assessment of slope instability on

future foundation designs with joined

up solutions

Construction support of pile

installation

Ground Modelling and

Geotechnical Risk

AssessmentsGood ground modelling is an essential part

of the geotechnical design and foundation

selection process. This is a combination of

geological and engineering expertise of soil

and rock types.

We use 3D ground modelling software

which is linked to our BIM Strategy for

structural works.

As part of the solution service, we offer a

fully coordinated site investigation strategyand manage all physical works through our

framework supply chain and strong links

to the Geotechnical Contracting Industry.

Services offered include:

Detailed desk study assessments

Specification requirements for

physical ground investigation works

Drilling services involving all

techniques compliant with Eurocode

standards

Geophysical techniques to

complement data acquisition

Soil & rock testing to assess design

parameters

Factual & Interpretative GeotechnicalReports

Geotechnical Specifications and

Specialist Contractor tender
