Specialized technical expertise for documentation, assessment, and intervention planning related to maritime heritage architecture.
We produce comprehensive measured documentation of existing buildings using integrated surveying methods. This typically includes laser scanning for overall geometry, photogrammetry for facade detail, and hand measurements for complex junctions or deteriorated areas where automated methods lack precision.
Deliverables include CAD drawing sets (plans, sections, elevations at 1:50 or 1:20 scale depending on complexity), annotated photographic inventories, and written reports describing construction systems and material conditions.
Documentation is structured to serve multiple uses: heritage nomination applications, condition assessment baselines, intervention design underlays, or archival records. We follow measurement and drafting standards established by Historic England and the National Park Service.
Development of detailed intervention strategies and coordination of implementation. This involves analyzing structural conditions, researching original construction methods, specifying appropriate repair materials, and preparing tender documentation for contractors.
During construction phases, we provide site observation services to verify that work follows approved conservation approaches and to address conditions that differ from what existing documentation suggested.
Our role involves mediating between heritage compliance requirements and practical construction constraints. We work to find solutions that satisfy both preservation standards and project budgets.
In-depth investigation of building histories through primary source materials. We examine construction permits, property transfers, insurance records, trade directories, newspaper accounts, and photographic collections.
This research establishes construction dates, identifies original owners and architects, documents alterations, and places buildings within broader economic and social contexts. Findings are compiled into narrative reports with source citations and relevant document reproductions.
Research results support heritage significance assessments, guide restoration decisions by clarifying what features are original versus later additions, and provide historical context for interpretation programs.
Laboratory analysis of existing materials to determine composition, identify appropriate replacement products, and locate suppliers. Common analyses include mortar characterization, timber species identification, and paint layer investigation.
We maintain relationships with specialized suppliers who can provide heritage-appropriate materials: lime-based mortars, reclaimed timber matching original species, period-correct hardware, and traditional glazing.
Preparation of applications for alterations to protected structures and liaison with heritage authorities. This includes assembling required documentation, preparing heritage impact assessments, and representing projects at permit hearings.
We advise on what categories of work require formal approval versus what can proceed under existing permits, helping to avoid compliance delays.
Systematic evaluation of building conditions with prioritized recommendations for intervention. Assessments document deterioration patterns, identify immediate hazards, estimate remaining service life for major systems, and project maintenance requirements.
Reports are structured to support budgeting decisions and long-term preservation planning. We distinguish between conditions requiring urgent attention and those that can be addressed through routine maintenance cycles.
For properties in maritime environments, assessments specifically evaluate salt damage, moisture infiltration patterns, and corrosion of ferrous elements—conditions that standard building surveys often overlook or misinterpret.
If you are considering heritage work on a port district property, we can provide an initial assessment of what documentation or intervention approach would be appropriate.
No-cost initial consultations are available for properties within the Cape Town metropolitan area.
