Technical Surveys UK | Building Retrofit Assessment

Q: What is a Technical Survey in the context of retrofit?

A Technical Survey is a detailed inspection of a building's physical condition and construction to inform retrofit planning and compliance. Unlike a standard Retrofit Assessment focused on energy performance, a Technical Survey examines construction type, existing defects, material condition, structural elements, and any factors that could affect the suitability or safety of proposed measures. It provides the evidence base for design decisions under PAS 2035.

Q: What does a StepSoft Technical Survey report include?

A StepSoft Technical Survey report typically includes construction type identification, condition of existing building fabric, photographic evidence, identification of defects such as damp, cracks, or structural issues, ventilation assessment, suitability assessment for proposed measures, and any pre-works required before retrofit can proceed. Reports are formatted for use in PAS 2035 project files and scheme submission packs.

Q: Can Technical Surveys identify issues that could fail a TrustMark audit?

Yes. Identifying issues such as pre-existing damp, unsuitable substrate, inadequate ventilation, or non-standard construction before installation begins helps avoid failed audits, non-conformances, and costly remediation. StepSoft technical surveys provide proactive risk identification across the project lifecycle.

Q: Do Technical Surveys cover both domestic and non-domestic properties?

StepSoft primarily focuses on domestic retrofit under PAS 2035, but can also support technical surveys for mixed-use or small non-domestic properties. Surveys are tailored to the specific construction, intended measures, and compliance requirements of the relevant scheme. Contact StepSoft to discuss project scope.

Technical Survey Services

At StepSoft Coordination Services, we provide comprehensive technical surveys to evaluate building conditions and support safe, efficient retrofit projects. Our experienced specialists conduct detailed inspections to gather accurate structural and performance data, ensuring that retrofit designs and installations meet PAS 2035 standards and regulatory requirements.

What are Technical Surveys?

Technical Surveys are detailed on-site inspections carried out to assess the structural condition and suitability of a building for retrofit improvements. These surveys gather essential information about the building’s construction, materials, and existing systems.

Accurate Building Assessment

Provides detailed information about the structure, materials, and condition of the building.

Support Retrofit Planning

Helps designers and coordinators develop practical and effective retrofit solutions.

Risk Identification

Identifies potential structural or installation challenges before retrofit work begins.

PAS 2035 Compliance

Ensures retrofit projects follow industry standards and regulatory requirements.

FAQ 's

What is a Technical Survey in the context of retrofit?

A Technical Survey is a detailed inspection of a building’s physical condition and construction to inform retrofit planning and compliance. Unlike a standard Retrofit Assessment focused on energy performance, a Technical Survey examines construction type, existing defects, material condition, structural elements, and any factors that could affect the suitability or safety of proposed measures. It provides the evidence base for design decisions under PAS 2035.

When is a Technical Survey required separately from a Retrofit Assessment?

A separate Technical Survey may be required when a property has complex, unusual, or non-standard construction — such as timber frame, pre-fabricated concrete (BISF, Wimpey no-fines), solid stone walls, or heritage buildings. It may also be commissioned by managing agents or local authorities seeking detailed condition data before committing to a large-scale programme, or where a previous assessment raised concerns requiring further investigation.

What does a StepSoft Technical Survey report include?

A StepSoft Technical Survey report typically includes: construction type identification, condition of existing building fabric, photographic evidence, identification of defects (damp, cracks, structural issues), ventilation assessment, suitability assessment for proposed measures, and any pre-works required before retrofit can proceed. Reports are formatted for use in PAS 2035 project files and scheme submission packs.

Can Technical Surveys identify issues that could fail a TrustMark audit?

Yes — this is one of the most valuable functions of a thorough Technical Survey. By identifying issues such as pre-existing damp, unsuitable substrate, inadequate ventilation, or non-standard construction before installation begins, StepSoft helps clients avoid failed audits, non-conformances, and costly remediation. Proactive surveying reduces risk across the entire project lifecycle.

Do Technical Surveys cover both domestic and non-domestic properties?

StepSoft primarily focuses on domestic retrofit under PAS 2035, but the team can also support technical surveys for mixed-use or small non-domestic properties. For any building type, the survey is tailored to the specific construction, intended measures, and compliance requirements of the relevant scheme.
