History

Dr. Uday Vaman Kulkarni,

Mrs. Rashmi Uday Kulkarni and

Shri. Vaman Kulkarni are the

founders of Noble Geo-

Structs. Dr. Kulkarni has a rich

experience in Geotechnical

investigation. Mrs. Kulkarni heads the

Human Resource Department and

executes the administration and

finance. Shri. V. M. Kulkarni is

responsible for the effective finance

management.

Noble Geo-Structs has provided

engineering, scientific and

construction services to the industrial

and federal sectors.

NGS offers comprehensive services

for wide dimension of clients to

optimize earth’s capacity be it for

sustaining the loads or be it

controlling the flow across the

structure. NGS integrates the latest in

Geotechnology to the needs of

structures above and deliver to our

clients the cream for the project.

Since our founding in 1995, we have

completed more than 5000 projects

all over the country. Although the

Geotechnical activities form the hub,

our services are also appreciated in

environment, transportation, water

resources and marine projects. NGS

considers it no less than an award to

find a place in the news papers for

the slope stability analysis work at

the Pune-Mumbai Expressway.

Dr. UDAY KULKARNI

Dr. Kulkarni, the Founder and

Executive Director of Noble Geo-

Structs has a rich experience of forty

years in the Geotechnical field.

He was appointed as a chief

consultant in order to assess and

suggest remedial measures for the

deep cuts and tunnels on Pune-

Mumbai Expressway. The redressal

measures taken up met the

challenges effectively.

The Kolkata metro faced an impasse

when a portion in front of the shield

tunnel collapsed. It was indeed

challenging to account for the weak

zone in front of the shield. Dr.

Kulkarni recommended

commendable measures to meet the

challenge.

Dr. Kulkarni graduated from Indian

Institute of Technology (IIT), Mumbai

(Powai). He completed his M.Tech

(Soils) in 1975 and Ph.D. (Geotech) in

1980. Dr. Kulkarni was awarded

a GOLD MEDAL for his paper on shear

strength of expansive soils.

Dr. Kulkarni's contributions to

the Konkan Railway project was

laudable, especially in the areas of

deep drilling for more than 100 m at

tunnel locations, geotechnical

investigation for bridges,

instrumentation for high

embankment, soft soil improvement,

testing of bridge spans and slope

stability.

Dr. Kulkarni is involved in large

number of consultancy projects

related to slope stability, soil

investigation, ground modification

and geosynthetics for soft soil, bridge

foundations, design of foundations

on expansive soils, shallow and deep

foundations and many such projects.

He has published large number of

research papers.

Dr. Kulkarni has undergone a special

training by Louis Menard, Paris,

France for ground improvement

techniques and pressuremeter

testing in 1980.

Reach

NGS is known for evolving creative

solutions to meet the challenges. The

state-of-art laboratory of NGS offers

unique facilities in testing the

engineering behavior of earth and

construction materials. The special

wing of Non-Destructive Testing

offers a large number of Engineering

Services to Rehabilitation projects,

Industrial sectors, Commercial

sectors and Infrastructure projects.

Our Mission

NGS usually approaches the problem

from first principles. With the

strength, the scientific team

undertakes diagnostic studies. NGS

analyzes the problem and suggests

corrective measures and draws

specifications. NGS also undertakes

the execution of the measures

whenever necessary. For very

sensitive structure, NGS evolves

perfect monitoring scheme in total

solutions for field problems.

Addressing project needs is the

primary goal in NGS endeavor.

PROBEX ROCK PRESSUREMETER

More and more consultants and contractors have recognized the benefits and

cost savings associated with the use of Pressuremeter test, an insitu test. Such

applications in Civil Engineering fraternity range from safe bearing capacity

evaluation, pile capacity assessment, tunnel liner design, for dam foundation and

other detailed sub surface studies. NOBLE GEO-STRUCTS has all the expertise and

equipment related to pressuremeter testing.

PROBEX PRESSUREMETER

The Probex Dilatometer is a radially expandable bore hole probe used to

determine insitu modulus of elasticity of soft and hard rocks. The Probex has

maximum working pressure of 30000 kpa. It also measures creep properties. The

ease of operation and reliable method of measurement and interpretation are

direct results of many years of experience with borehole pressure meter.

Features:

High capacity - 30000 kPa

Evaluate Young’s Modulus

Noble Geo-Structs provides a wide

range of design services for

foundations and earth retention

structures. Projects where these types

of services are provided typically

involve development of innovative

designs using specialty construction

techniques to provide cost-effective

construction solutions in difficult

terrain or in conditions where

conventional solutions are unattractive

we routinely perform analyses and

prepare designs for owners and

specialty contractors.

Many of these projects involve failed

or failing slopes in extremely difficult

soil and rock conditions.

Our experience with foundation and

earth retaining structures includes

design and consultancy services for:

Soil nailed slopes

Reinforced earth walls

Micropiles

Ground Improvement

o Sand drain, Band drain

o Stone column

o Geofabric applications

o Gabions

Services to the water supply and

infrastructure sectors represent an

important portion of NGS’s business. In

response to the ever-increasing

demand of water supply and the

increasing use of more efficient and

more sustainable conveyance methods

to transport water, NGS has applied its

capabilities to meet the changing

demands. The NGS tunneling projects

also include design and consultancy for

the highway and railway sectors.
