Full title and description

SNT 2.02.01-2016 — Foundations of buildings and structures. Technical normative document providing requirements and recommendations for geotechnical investigation, design and construction of foundations and other ground-related works for buildings and structures used in Turkmenistan.

Abstract

This standard sets out principles and mandatory rules for the investigation of subsurface conditions, classification of geotechnical categories, design of shallow and deep foundations, assessment of bearing capacity and settlements, methods of ground improvement and measures to ensure durability and safety of foundations under the climatic and seismic conditions addressed by the document. It replaces earlier national editions and aligns technical content with regionally used practice for foundation design.

General information

• Status: Active (national SNT in force since 2016).
• Publication date: 2016 (approved by the Ministry of Construction and Architecture of Turkmenistan in early 2016; officially published/registered in 2016).
• Publisher: Approved by the Ministry of Construction and Architecture (Türkmenistanda Gurluşyk we binagärlik ministrligi) / national standards authority for construction.
• ICS / categories: Foundations / geotechnical engineering (sector: building construction; comparable ICS classification: 93.020 — foundations of buildings and structures).
• Edition / version: 2016 edition (SNT 2.02.01-2016).
• Number of pages: 74 pages (electronic/pdf distribution commonly available).

Scope

The standard applies to the planning and execution of geotechnical investigations, selection and design of foundations (shallow and deep), assessment of bearing capacity and settlements, and decisions on soil improvement and foundation protection for buildings and structures covered by national construction practice. It provides criteria for assigning geotechnical categories, requirements for design documentation, and rules to ensure reliability, durability and safety of foundations under expected loads and environmental conditions. The scope is intended for use during project design, construction and technical inspection stages.

Key topics and requirements

• Geotechnical site investigation: scope, allowable study methods and reporting requirements.
• Classification of geotechnical categories and assignment rules tied to object importance and site complexity.
• Principles for design of shallow foundations, deep foundations (piles), and raft foundations, including limit states and calculation procedures.
• Bearing capacity and settlement criteria, recommended permissible settlements and differential settlement limits for various building types.
• Requirements for ground improvement, reinforcement and soil stabilization techniques where native soils are inadequate.
• Measures for frost protection, drainage and waterproofing of substructure elements.
• Consideration of seismic and other extraordinary actions in foundation design where applicable.
• Requirements for design documentation, construction control and record-keeping for foundation works.

Typical use and users

Primary users are geotechnical and structural engineers, design institutes, architects, site investigation teams, contractors involved in foundation works, and regulatory bodies overseeing building safety and permitting in Turkmenistan. International consultants working on projects in the country also use this SNT as the national reference for foundation design and geotechnical practice.

Related standards

Related and historically connected documents include the earlier national edition SNT 2.02.01-98 (replaced by the 2016 edition), regional/legacy СНиП/SП documents on foundations (for example СНиП 2.02.01-83* / СП 22.13330.2016 in Russian practice) and other SNT/TGK series standards addressing corrosion protection, construction climatology and seismic design. Users should consult adjacent SNT/TGK documents for requirements on anticorrosion protection, geotechnical investigation procedures and seismic provisions.
