M.Venkataraman, GWRL. TECHNICAL SPECIFICATIONS  Properties :  Polymer Composition, Structure & Physical Properties  Mechanical Properties  Hydraulic Properties  Survivability  Installation Practices  UV Resistance

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

Reinforcement - 1 Reinforcement - 2 Strain (%) Load (kN/m) 2 5 Eg: Reinforcement application It is more relevant to specify long-term strength & strength at 2% and 5% strain rather than Ultimate Strength TECHNICAL SPECIFICATIONS

M.Venkataraman, GWRL. TECHNICAL SPECIFICATIONS  Dictates the exact materials to be used in a project  No guarantee that the best available product is delivered  They focus on the Specifications and not on the Final Output (Performance)

M.Venkataraman, GWRL.  Aspects :- Application Function Product STANDARDIZATION OF SPECIFICATIONS  Primary - Main Properties Specifications  Secondary - Min. Properties  Any product which satisfies the Primary and Secondary specifications can be selected

M.Venkataraman, GWRL.  Eg: As per IRC:SP: :- Separation & Filtration functions (unsaturated soils) AOS = 0.6 mm, Max. Value Permittivity = 0.02 Sec -1, Min. Value  Subsequently, specifies minimum strength requirements (Type I, II and III) for a geotextile depending on Installation Damage  Any geotextile with satisfies the criteria can be selected STANDARDIZATION OF SPECIFICATIONS

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

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

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

BENEFITS OF CERTIFICATION  Design considerations -Long-term different temperatures -Installation damage factor for different size of fill material -Factor for Environmental effects (pH range) -Factor for manufacturing, extrapolation & database

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

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

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)

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)

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:

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

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

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 PERFORMANCE RELATED SPECIFICATIONS  Barriers

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 WORLDWIDE SCENARIO

M.Venkataraman, GWRL. ROAD MAP TO THE FUTURE VISION Better translation of design and performance requirements into specifications MISSION Establish Performance Related Specifications

M.Venkataraman, GWRL. ROAD MAP TO THE FUTURE GOALS  Identify relationships that link design and construction with product performance  Develop and Implement Performance Specifications Freedom to innovate with accountability to deliver DRIVING FORCE
