Unit 2 Construction Technology - Pearson Higher Nationals in Construction and the Built Environment
Construction Substructure and Superstructure
Learning Outcome 1: Discuss the terminology used in construction technology.
Learning Outcome 2: Describe the different techniques used to construct a range of substructures and superstructures, including their function and design selection criteria.
Assignment Brief
You are working as an Architectural Technician for a large design practice and your employer has asked you to produce ‘design consideration' pamphlets to be distributed to new employees. The documents are to consider the functional requirements and design selection criteria for different elements of typical commercial building including installing pile foundations.
Section A Technical tasks
Reinforced Concrete Column Design-The permissible load for a reinforced concrete column.
A modular ratio represents the amount of load that a square unit of steel can safely transmit relative to that of concrete. A figure of 18 is normal, with some variation depending on materials specification and quality.
The following tasks are related to the above rectangular reinforced column
(a) Explain the main functions of reinforcements in Columns
(b) Explain the term the effective length of a column
(c) Calculate the area of the concrete
(d) Find the equivalent steel area
(e) Using concrete with a safe or working stress of 5 N/mm2, find the factor of safety
(f) Calculate the maximum permissible load
Using the previous example assume the working stress unit for concrete to be taken as 0.8 times the maximum working stress of concrete where the effective length of column is less than 15 times its least lateral dimension....
Section B Research tasks
Document 1: Substructures
This document should consider the pre-design studies to be carried out and the type of information to be collated in order to design the most suitable foundation type for different types of structures. The document should also consider the construction of different types of foundations and their suitability for use with different types of structures. The information will be presented through pamphlets (a small booklet or leaflet containing information or arguments about a single subject.)
Document 2: Superstructures
This document should consider the following elements of the superstructure:
• Walls
• Roofs
• Floors - ground and intermediate
• Windows and doors
• Staircases
• Finishes
The document should contain a description of the functional characteristics of each of the above elements and the design selection criteria for their use.
Both documents should contain diagrams to illustrate the content. Each pamphlet is to be indexed with a checklist for use by technicians when carrying out design considerations.
