Services

Building surveying & property advisory across the full lifecycle.

5AB provides building surveying, project and advisory services to commercial, public sector and residential clients. All instructions are personally carried out and overseen by the principal surveyor.

01

Building Surveys & Defect Diagnosis

Building surveys that give a clear understanding of a property’s condition, together with the investigation and diagnosis of building defects. Reports set out likely causes, remedial options and priorities for repair, for purchasers, owners and occupiers.

Commercial & Residential
02

Technical Due Diligence

Pre-acquisition and pre-lease technical due diligence for investors, lenders and occupiers across all commercial asset classes. Clear reporting on condition, compliance and anticipated capital expenditure, identifying risks that may affect value, lending or transaction terms.

Commercial & Investment
03

Dilapidations

Dilapidations advice for landlords and tenants throughout the lease cycle, including schedules of condition at lease commencement, interim and terminal schedules of dilapidations, the assessment of and response to claims, and the negotiation of settlements in line with the Dilapidations Protocol. Advice on lease-end strategy is also provided.

Landlord & Tenant
04

Party Wall & Neighbourly Matters

Advice under the Party Wall etc. Act 1996 for building owners and adjoining owners, including the preparation and service of notices, schedules of condition and party wall awards, and acting as agreed surveyor where appointed. We also negotiate access, scaffolding and oversail licences with neighbouring owners.

Building & Adjoining Owners
05

Project Management & Contract Administration

Whatever the construction, refurbishment or development project, 5AB can deliver it from conception to completion. We carry out the initial surveys, prepare specifications and schedules of works, and work with the wider consultant team to produce a robust tender package. We manage the full tender process, assist with the selection and appointment of the contractor, prepare the building contract under JCT, NEC or other standard forms, and act as contract administrator on site through to completion. Planning and Building Regulations approvals are coordinated, and client duties under the CDM Regulations 2015 are advised on throughout. Regular reporting, agreed at the outset, keeps you informed and takes the day-to-day pressure of the project off you.

All Sectors
06

Planned Maintenance & Lifecycle Reporting

Planned preventative maintenance surveys and lifecycle reports that prioritise repairs and replacements over the life of a building, with budget costs to support capital expenditure planning and long-term asset management.

Investors & Asset Managers
07

Reinstatement Cost Assessments

Reinstatement cost assessments for insurance purposes, prepared in line with RICS guidance, establishing the cost of rebuilding a property to help owners and managing agents avoid under-insurance. Available for single assets or portfolios, with periodic reviews to keep assessments current.

Owners & Insurers
08

Development Monitoring

Independent monitoring on behalf of funders, lenders and investors, from an initial review of the appraisal, budget, programme and contracts, through regular site inspections and progress reporting, to the verification of drawdowns and practical completion.

Lenders & Funders

Further Services

Feasibility Studies & Design

Working with clients to establish what can be achieved with a property, whether remodelling for a change of use, extending, making better use of space or improving compliance with current Building Regulations. Option appraisals consider planning implications, Building Regulations compliance, health and safety and indicative costs, supported by outline design. Where specialist input is required, 5AB can act as your single point of contact, coordinating specialist consultants to move the project forward.

Measured Surveys & CAD Floor Plans

Measured building surveys producing accurate CAD floor plans, elevations and sections, with floor area schedules prepared in accordance with RICS property measurement standards.

Condition Surveys

Condition surveys for clients who require a clear record and assessment of a property’s condition rather than a full building survey, for example before entering into a lease, acquiring a property or planning works. Photographic schedules of condition are also prepared as part of party wall and dilapidations instructions.

Licence to Alter & Landlord Consents

Advice to landlords on tenants’ proposed alterations, including review of drawings and specifications, preparation of licence schedules and inspection of completed works.

Residential Surveys

RICS Home Surveys at Levels 1, 2 and 3, carried out in accordance with the RICS Home Survey Standard, together with party wall, measured survey and design services for homeowners. Property valuations are not offered at the moment.
