The series consists of approximately 23,000 aperture cards created by the Dept. of Public Works between 1969 and 1978, to manage historic building plans and drawings of public buildings throughout British Columbia. The plans include those for law courts, highways maintenance yards, police buildings, hospitals and health centres, government office buildings, liquor stores, correctional centres and camps, sewage treatment plants, fire halls, civil defence buildings, vocational schools, universities, mental health institutions, provincial schools and the Provincial Legislative buildings.
Each card contains a 35 mm microfiche copy of a plan or drawing made from a negative of an original plan, along with Public Works Drawing number and the negative number assigned to the 105 mm version of the plan or drawing. The cards are arranged numerically by the PWD number. Use the indexes to Public Works building buildings plans (GR-2184) in order to determine the PWD number.
Three groups of numbers and/or letters were used to make up the drawing number. The first group consists of numbers only and indicates the assigned area number. The second group consists of a letter or figure which denotes the type of plan.
When the drawing was used as a site plan, topographical plan or services (utilities) plan one of the following letters was used:
A - Architectural perspectives
E - Electric distribution, exterior floodlighting, street lighting etc. systems
L - Landscaping
M - Mechanical Services distribution systems
S - Site & topographical plans, excavation, levelling, roads, parking areas, sewage, water distribution and collecting systems
When the drawing was used as a building plan, the three part number consisted of area number, building number and sheet number.
The third group consisted of a letter/number group denoting the type of drawing and sheet number using the following letters:
A – Architectural
E – Electric circuitry and detail pertaining to the building
F - Furniture and fixtures
M - Mechanical
P – Plumbing
S – Civil/Structural
When an alteration (revision) was made to an existing plan, the new trace bears the same number as the original drawing, followed by an oblique stroke and number indicating the alteration.
When a new wing or extension was made to an existing building, the drawing would bear the first two groups as the original drawing but the third group started at 201. A second wing or addition to the same building would bear sheet numbers starting at 301.
