Surveying a historic Grade II listed school in Hertfordshire

Haberdashers’ Girls’ School and Haberdashers’ Boys’ School are independent day schools for girls and boys aged 4 to 18. With roots tracing back to the 17th century, the schools have moved location several times but now comprise of a collection of buildings and a surrounding estate – including the Grade II listed Aldenham House in Elstree, Hertfordshire.

Although separate schools, the girls’ and boys’ schools now share a campus, offering single-sex education in a co-educational environment.

Collating existing information to deliver drawings and floor plans

Over 10 years ago, the Head of Estates at Haberdashers’, commissioned CADS to deliver drawings and floor plans of both schools. The Haberdashers’ schools had existing data, including architects’ plans from a heritage survey of the listed building, as well as other out-of-date survey plans from various architects, surveyors and sub-contractors.

Initially, our team were asked to collate the existing drawings and floor plans to create one pack of drawings which could be used for future amends or updates. Since then we have worked on a number of projects, including collating existing information and conducting measured surveys – to provide the school’s Estates Department with complete and up-to-date information to assist in the day-to-day facilities management activities across the campus.

Providing a measured survey to capture new data

After bringing the existing information together, Simon Ruddick, our Senior Geospatial Technician, discovered there were no architects’ plans for some of the boys’ school buildings.

So, to fill the gap in the data, our team undertook a measured survey of two further buildings on the site, including the new Penne changing rooms, to ensure the school had complete and up-to-date plans.

After conducting the survey, we combined the existing and new data to deliver simplified 2D drawings as floor plans in PDF format – complete with school blocks which were colour coded to identify subject areas such as the science block.

Delivering ongoing services for the schools

Following the initial project, we have continued to regularly provide a number of services and deliverables for the Haberdashers’ schools under a framework agreement, including:

1. Creating digital drawings of the Science Tech Lab, enabling the school to undertake refurbishment works

2. Producing a general arrangement ground floor plan of Aldenham House, for planning work on the Technical Services staff office

3. Scanning existing hard copy drawings and converted to the same format as those used by Haberdashers’ Girls’ School, to create a CAD base plan, followed up with a site visit to audit and update the internal layout

4. Completing a laser scan survey when a gap analysis identified incomplete ground buildings and pavilion plans.

5. Surveying seven of the Haberdashers’ Boys’ School buildings to create 2D drawings for the design centre

6. Updating the switchgear plan, site plan plots, fire hydrant updates and LV plans.
