Welcome to the sixteenth edition of the flagship publication of IndSTT, the Schedule of Rates for Construction Contracts Employing Trenchless Technology 2024 (SoR). As we embark on another year, it is with great pride that we present this essential guide, building upon the legacy of the previous edition.

Much like its predecessors, this edition of the SoR remains a valuable resource for the construction industry, specifically tailored to aid in planning, budgeting, bidding, and contracting for trenchless construction projects. The realm of trenchless technology continues to offer intelligent solutions to the myriad challenges faced by utility owners, making it a pivotal aspect of modern construction practices.

The importance of accurate cost estimation in the context of state-of-the-art trenchless solutions cannot be overstated. As we progress into this new edition, the SoR stands as an indispensable tool for project stakeholders, facilitating techno-commercial evaluations of trenchless project proposals. Since the inception of this initiative in 2002, IndSTT has consistently published schedule of rates, and we are honored to present the sixteenth edition, reaffirming our commitment to serving the Indian trenchless industry.

Unit rates of work items play a crucial role in the standardization process, serving as the linchpin connecting specified operations to their corresponding measurement modes. This edition of the schedule of rates maintains its comprehensive coverage, encompassing approved Trenchless Techniques and their support activities.

Building on the success of the previous year, we proudly continue the inclusion of a dedicated section outlining the minimum technical competencies expected from trenchless operators and technicians. This section, crafted based on the requisite work components for successful construction projects, sets benchmarks for the evaluation of skills in trenchless techniques. Our commitment to transparency is exemplified through the initiation of trenchless skill testing and certification, providing a reliable system for assessing worker skills and ensuring project stakeholders can confidently select qualified operators.

As technology evolves and more techniques undergo standardization, we anticipate the continued growth of these minimum standards. Subsequent editions of this book will incorporate these evolving standards, and we encourage project authorities to utilize them for verifying the skills of operators or seek IndSTT Certification for operators and technicians proposed for deployment on their projects.

With numerous subsurface projects currently underway, this book addresses a significant need within the construction industry. I extend a warm invitation to stakeholders to maximize the benefits of this publication in their endeavors.

We express our sincere gratitude to the trenchless construction industry for their continued trust in this publication. We look forward to its continued success in this edition and beyond. We invite stakeholders to actively contribute their insights for the inclusion of new items and modifications to ensure the SoR remains in step with the changing needs of the industry.
