Ensure the quality of earthworks and foundation construction from the very beginning

Why RYL?

• When you refer to the RYL service in your tenders and contracts, all contractors receive the same quality requirements at once. This makes tenders easier to prepare and compare.
• You do not need to repeatedly define detailed requirements for every work phase from project to project in contracts and tender documents.
• RYL also simplifies the preparation of project-specific documents (construction specifications, work descriptions), eliminating the need to repeat the same requirements across projects.

Designer – Ensure Accurate Input Data and Design Criteria

A geotechnical designer investigates soil conditions and determines how structures should be founded, as well as how bearing capacity, settlement, and groundwater issues are managed.

Instead of describing every implementation quality requirement separately, design documents refer to MaaRYL requirements.

During construction, MaaRYL serves as a common framework supporting implementation according to the design.

Benefits for Designers

• Supports constructability of designs
• Reduces ambiguity during construction
• Harmonizes requirements between design and execution
• Helps ensure solutions are implemented as intended

Infrastructure Client and Project Owner – Ensure Reliable Results Below the Surface

The client initiates infrastructure projects such as roads or logistics areas, where the quality of earthworks plays a critical role in durability, maintenance, and lifecycle costs.

Tender documents reference MaaRYL, ensuring earthworks requirements are clear and consistent for all bidders.

During the contract phase, MaaRYL serves as a common foundation for execution.

Benefits for Clients

• Consistent quality throughout the project
• Better cost and risk management
• Less uncertainty during execution
• Durable results throughout the asset lifecycle

Earthworks Contractor – Manage Materials, Layers, and Bearing Capacity

The contractor carries out excavations, fills, embankments, and structural layers.

MaaRYL guides work methods, material requirements, and compaction to ensure the finished result meets the intended bearing capacity and functionality.

Benefits for Contractors

• Clear requirements for different work phases
• Fewer uncertainties when interpreting plans
• Better predictability of work
• Fewer repairs and rework

Supervisor and Specialist – Measure Quality, Not Opinions

The supervisor ensures that infrastructure work complies with contracts and technical requirements.

InfraRYL provides concrete criteria for evaluating the quality of structures, materials, and execution.

This means assessments are based on shared rules rather than subjective interpretation.

Benefits for Supervisors and Inspectors

• Objective benchmark for quality assessment
• Clear support for resolving disputes
• Easier documentation and reporting
• Ensures compliant outcomes

Site Equipment Operators and Installers – Get It Right the First Time

Excavator operators, compaction equipment operators, and installers physically construct the structural layers.

MaaRYL provides concrete requirements for compaction levels, layer thicknesses, implementation methods, and more.

Benefits on Site

• Easier verification of product compliance
• Supports sales and technical justification
• Facilitates cooperation with designers and contractors
• Clarifies documentation
