ABOUT

Overview

Waterford City & County Council is refurbishing a group of social housing units that have stood vacant for a long time. An Irish survey company hired to record these properties needed the scan data converted into usable 3D models and construction drawings, and outsourced that work to Scan to BIM Services UK.

The programme covered 11 units - houses at Ardmore Park, The Crescent (St. John's Park), Dominick Place, Johnstown, Sion View Terrace and Tycor Water Works in Waterford City, a property on Shandon Street in Dungarvan, and The Bungalow at Coolroe. Each house type was to be modelled in Revit at LOD 300 and documented in a full drawing set.

PROJECT SCOPE

The Brief

The client supplied scans of the existing units, photographs of the houses and a sample Revit model from a different housing project, which served as a reference for sheet layout, model detailing and working method.

From these inputs, the scope was to build an architectural model of each house type and prepare construction drawings from it:

  • Interior, exterior and ceiling modelling, including walls, doors, windows, openings, staircases, roofs, basic furniture and fixtures, all placed in accordance with the scans
  • Sheet set-up for floor plans, sections and elevations
  • Tagging, annotations and dimensioning on every drawing
KEY CONSTRAINTS

Challenges

01

Poor scan quality

Some scans were unclear and hard to interpret, which made building an accurate model from them slow and demanding.

02

Reliance on photographs

Because the scans were blurry, the team had to rely heavily on photographs of the houses to confirm details and keep the model and drawings accurate.

03

Compressed schedule

The first six house types had to be modelled and compiled into drawing sheets in just 5 working days.

04

Staggered data

Not all scans were available at the start of the project, so the remaining five house types had a very short turnaround once their data arrived.

OUR PROCESS

Our Approach

Step 01

Review of Scans, Photographs and Reference Model

We studied the scans and house photographs alongside the sample Revit model to understand the client’s expectations for model detail, sheet content and working process before modelling began.

Step 02

LOD 300 Revit Modelling

Each house type was modelled in Revit from the scans, with photographs used to resolve unclear areas. The models covered:

  • Walls, doors, windows and openings
  • Staircases and roofs
  • Interior, exterior and ceiling elements
  • Basic furniture and fixtures
Step 03

Construction Drawings

From the models, we set up the drawing sheets for floor plans, sections and elevations, adding tagging, annotations and dimensions so that each set was ready for use by the client.

RESULT

The Outcome

Scan to BIM Services UK delivered the LOD 300 Revit models and construction drawings for all 11 housing units within the client’s timelines, despite unclear scans and late-arriving data.

The project became a benchmark for our team. It strengthened our experience in:

  • Coordinating all phases of the model
  • Working from scan data
  • Producing detailed construction drawings in Revit
  • Completing projects within tight time limits while delivering the output the client required
