NEW CHALLENGES
In recent years, while providing a solution, the
Engineer has to face increased challenges:
Various site constraints like space, alignments etc.
Tight time schedules
Ensure max. usage of local resources (Material &
Manpower), hence Cost effective!!
Least environment impact
Long term performance & higher Cost benefit ratio over
a larger period of time (Least maintenance cost)

27. M.Venkataraman, GWRL.
TECHNICAL SPECIFICATIONS
 Present Scenario:
•For any application, the technical specification
includes all the properties as mandatory
requirements irrespective of the function to be
satisfied
It is significant to specify the properties critical
for the function

28. Reinforcement - 1
Reinforcement - 2
Strain (%)
Load
(kN/m)

Eg: Reinforcement application
It is more relevant to specify long-term strength &
strength at 2% and 5% strain rather than Ultimate
Strength

34. CERTIFICATION – WHY ??
CONFIDENCE IN SELECTION OF PRODUCTS
BY SPECIFIERS / CLIENTS

35. CERTIFICATION PROCESS
Comprehensive Assessment:
- Laboratory Testing
- On-Site Evaluations
- Production Inspection
- Consistency in Material Quality

36. BENEFITS OF CERTIFICATION
Independently verified technical specifications
Product scope / compliance with relevant
materials / system
Tests – highest level of accuracy
Specifies the durability of the product in the
system

37. BENEFITS OF CERTIFICATION
Design considerations
-Long-term strength @ different temperatures
-Installation damage factor for different

size of fill material
-Factor for Environmental effects (pH range)
-Factor for manufacturing, extrapolation &
database

38. BENEFITS OF CERTIFICATION
Installation guidance &
handling of materials
Limitation / Risks – if any
Monitoring of Product manufacturing during the
tenure of the Agrément

39. M.Venkataraman, GWRL.
Standardization of Specifications & Certification
eventually will help to develop Performance
Related Specifications (PRS)
Performance Related Specifications – Why ??
PERFORMANCE RELATED
SPECIFICATIONS (PRS)

40. M.Venkataraman, GWRL.
Performance specifications describe how the
finished product should perform over time
It is the bridge between design, construction
quality, and long-term product performance
Specifications that use quantified quality
characteristics and life cycle cost relationships
correlated to product performance.
PERFORMANCE RELATED
SPECIFICATIONS (PRS)

41. M.Venkataraman, GWRL.
Performance Parameters
– Depends on the Product and the application
Governing Factors
End Result Elements:
- Bearing capacity, stability, settlements,
cracking, etc.,
Functional Requirements:
-Smoothness, friction, etc.,
PERFORMANCE RELATED
SPECIFICATIONS (PRS)

42. M.Venkataraman, GWRL.
•Critical Quality Characteristics
–Measurable and tied to product performance
•Prediction Tools (modelling and databases)
–Verified, calibrated, validated, and made
appropriate for local conditions
•Life Cycle Cost Analyses (LCCA)
–To compare the as-designed product section to
the as-built section
PERFORMANCE RELATED
SPECIFICATIONS
 Fundamental Requirements:

43. M.Venkataraman, GWRL.
Improved link between Design and Construction
Improved and focused testing on characteristics
related to performance
Promoting best practices to improve quality
Improving Flexibility, Efficiency and Value of the
system
 Benefits
PERFORMANCE RELATED
SPECIFICATIONS

44. M.Venkataraman, GWRL.
Adding private sector innovation
Allow contractors more freedom to implement
their own procedures, choose their own
equipment, and conduct site-specific process
control programs
Transferring risk away from the owner
PERFORMANCE RELATED
SPECIFICATIONS
 Benefits

45. M.Venkataraman, GWRL.

Determining good performance criteria and
measures
Potential impacts to contractors performance bonds
A drastic change in corporate culture
Openness and Trust
Change of Industry mind set
Focus on solution rather services
Delivery driven by value not cost

 Barriers

46. M.Venkataraman, GWRL.
 Premier Institutes and Agencies implementing PRS
•FHWA
•AASHTO
•European Union
•UK
•DOT, California (Caltrans)
Winconsin, DOT experienced 36% improvement in
highway ride quality & 10% savings in LCC using PRS in
Pavements
