CRAF7001 - Carpentry - Domed Roofs

Title:Carpentry - Domed Roofs
Long Title:Carpentry - Hexagonal Roof and Circular Domed Roof
Module Code:CRAF7001
Credits: 5
NFQ Level:Intermediate
Field of Study: Craft
Valid From: Semester 1 - 2015/16 ( September 2015 )
Module Delivered in 1 programme(s)
Module Coordinator: MICHAEL HOURIHAN
Module Author: BRIAN THOMA
Module Description: This module introduces students to the complex geometry involved in the construction of polygonal Ogee Roofs and Domed Roofs. The complex nature of compound angles and curvilinear rafters will require high level problem solving skills gained in the practice of roofing geometry.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Design, set out and make, using the geometric principles of roof construction, a hexagonal Ogee roof.
LO2 Design, set out and make using geometric principles a circular domed roof to include identifying various types of dome roof constructions available.
LO3 Apply appropriate jointing and fixing of wall plates; Producing curved dihedral bevels generated by hexagonal Ogee roof rafters.
LO4 Cut and fix tiling battens and sheeting to a domed roof.
LO5 Propose and implement solutions involved in a domed roofs with reference to interlocking structures and aesthetics.
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
No recommendations listed
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.

Module Content & Assessment

Indicative Content
Workshop Practice
Safe practice in the design and production of a polygonal Ogee and a circular domed roof. Produce a scale model of a polygonal Ogee and dome roof.
Cut and construct a polygonal Ogee roof and a domed roof including hip rafters, jack rafters, finial and tiling battens, using Jigsaw, CNC where appropriate.
Natural softwood PAO, manufactured boards, preservative, metal fasteners.
Design & Problem Solving
Scale drawing developed using geometric principles to include hip rafters, jack rafters wall plates. Produce solutions to a given situation resulting from Ogee and Domed roof structures.
Determination of bevels and lengths, cutting to bevels and lengths, fixing, nailing roof components. Identify solutions to proposed interlocking rafters or components, using appropriate structural techniques.
