Audience and Scope of Description
The purpose of this document is to provide the reader with a basic understanding of how medieval builders constructed Gothic Cathedrals. The document will demonstrate the process of how medieval builders constructed the vaults. In addition, the document will identify characteristics of Gothic Cathedrals, terminology, and types of vaults. After reading this document, the audience will be able to identify the key components of a Gothic Cathedral. The intended audiences for this document are engineering and architecture students interested in medieval construction. The document could appear in a lecture handout. Students should gain a better understanding of Gothic design principles. This general understanding will be beneficial to the students who would like to pursue a career in historic preservation.

Introduction to Process
In order to understand gothic architecture, students must understand the goals of medieval builders. Medieval builders desired to construct tall buildings that allowed as much natural light as possible. Therefore, they needed to design and build higher ceilings and more transparent faades. In order to do this, they constructed vaults to provide these buildings higher ceilings.

Gothic Principles
In the study of gothic architecture, it is important to be familiar with the terms and principles. Also, it is important to understand how the load is distributed through the structure to understand medieval design. Medieval builders modified their design as they worked. They wanted the Gothic cathedrals to have large curtain walls filled in with stained glass. Therefore, these walls could not support the weight of the vaulting and roofs. As a result, they developed an external system of buttressing (seen in the figure below), which applied counter-acting force sideways towards the cathedral wall. This resists the tendency of the walls to bulge out from the lateral pressures. The upper flying buttress redirects the wind forces from the roof and the clerestory wall, guiding them downwards into the pier buttress (aberlard.org). Gothic architecture is characterized by flying buttresses, the pointed arch, and the ribbed vault. Further description of these gothic characteristics is defined in the document.

Gothic Terms
Buttressing A structure, usually brick or stone, normally a half arch carrying the thrust of a roof or vault across an aisle to an outer pier or buttress.
Centering A temporary, usually wooden frame on which an arch, vault, or dome is supported during construction.

Pointed Arch An arch with a pointed top. This is a major characteristic for a gothic architecture.

Shoring The vertical or truss supports are used as a temporary replacement for the building buttressing or walls during construction.

How a Gothic Vaults are Constructed
ROOF SHORING Medieval builders constructed the shoring for the roofs using nails and mallets.

ROOF The medieval builders laid out shoring for the construction of the roof and laid a floor to hold the millwheel for construction of the vaults.

TREADWHEEL CRANE The treadwheel crane was installed on top of the area for the vaults. The medieval builders laid out centering for the ribbed vaults.

CENTERING OF VAULTS The centering was constructed at the end of the vault to prepare for the application of brick.

VAULTS The medieval masons applied brick over the vaults shoring.

VAULTS The final step for the construction of medieval vaults was the builders applied a layer of plaster to the vaults.

Gothic Vaulting
There are 7 types of vaults which are listed below:
Barrel Vault Ribbed Barrel Vault Groin Vault Domed Groin Vault Ribbed Vault Quadripartite Vault Sexpartite Vault
Barrel Vault
A roof consisting of a series of semi cylindrical arches (Britannica.com).
Ribbed Barrel Vault
Semi cylindrical arches which ribs help to support the vault.

Groin Vault
Two barrel vaults that intersected at right angles form a groin vault (Britannica.com)
Domed Groin Vault
Two intersecting barrel vaults that are raised to a spherical dome roof.

Ribbed Vault
A vault in which stone ribs carry the vaulted surface (Britannica.com).
Quadripartite Vault
A groined vault defined by ribs on each side and divided into four parts.

Conclusion
In conclusion, gothic cathedrals have three characteristics: buttressing, pointed arch, and ribbed vault. The medieval masons used the engineering to design the buildings to allow more height and light. They developed 7 types of vaults. Architecture and engineering students understand and appreciate these design methods by medieval builders. They can be applied further into their careers, perhaps in historic preservation.
