My Background
Ibegan my PhD at the University of Winchester in Feb 2006
supervised by Prof Tom Beaumont James & Dr K Wilkinson
and advised by Mr Edward Roberts
started life destroying old buildings
how can I save these buildings and raise their awareness?
I wanted to combine my two passions
old buildings
technology

Background to my research
researching late medieval timberframe buildings
concerned with jointing and
framing techniques
houses were prefabricated(Harris 1978)
joints were created by the master
carpenter
basic joints are similar
dendrochronology is the most
significant advance in datingbuildings [since c14](Morriss 2000)

Previous workPrevious work
by examining all these examples of frame-work we have
been able to prove, despite their great variety, that eachperiod is characterised by definite assembly-methods
(Deneux, 1927)
1980 Cecil Hewett writes
English Historic Carpentry
focused on the Essex area
based on teleological progression
lack of scientific methodology
dendrochronology not used

dendrochronologydendrochronology
Dendrochronology, or tree-ring analysis, is a highly technicalspecialist process that relies on powerful computertechnology and skilled technicians. (Morriss 2000, 142)
trees of the same species, growing during similar time
frames in localised habitats, will produce similar growth-ringpatterns
dendrochronology was pioneered in North America by
Douglas during the first decades of the 20th century
Baillie produced a full Oak chronology in 1988 forIreland, itnow goes back 7,272 years in northern Europe

Recalibrating Hewett
in the light of dendrochronology, buildings archaeologistscan now recalibrate Hewett's dates
With solid dates we can also revaluate any significance in
the changes in style and techniques alongside historicinformation

Collecting the data
fieldwork and surveying
recording dimensions, carpenters marks, joint types,
locations etc.
in the field by direct data entry into MS access, AutoCAD and
SketchUp
direct data entry mitigates dyslexia
high quality digital photographs to provide context and basis
for models

Traditional 2D illustrationsTraditional 2D illustrations
2D illustrations can lack depth, context and meaning
they remain static
tend be an exploded view
not easy to read
non-scalable

be manipulated intoshowing a more appropriate view
they can be animated to show
how the joints fit together

pplying geomatics to timber-famed structures
geomatics is the discipline of gathering, storing, processing,and delivering of geographic information
uses GPS, GIS, maps, satellite imagery
used to record, analyse, cognate and visualise spatial
information
As computer technologies advance, so too, does the tool setavailable to buildings archaeologists

Geographical Information Systems (GIS)
is a system for capturing, storing, analysing and managingdata and associated attributes which are spatially referenced
to the earth
a tool to collate and manipulate spatial data
goes beyond conventional mapping
key advance in the cognitive sciences
