Unit 2 Construction Technology Assignment Brief

Qualification	Pearson BTEC Higher Nationals Construction
Unit Number	2
Unit Title	Construction Technology
Unit code	J/618/8081
Unit level	4
Credit value	15

Introduction

The basic principles of construction technology have not changed for hundreds of years. However, the materials and techniques used to achieve these basic principles are constantly evolving to enable the construction industry to deliver better quality buildings. Scarcity of resources and the continuing demand of more sophisticated clients, end users and other stakeholder interests, are driving the construction industry to provide buildings that facilitate enhanced environmental and energy performance, and greater flexibility. This is in response to ever-increasing financial, environmental, legal and economic constraints.

This unit introduces the different technological concepts used to enable the construction of building elements, from substructure to completion, by understanding the different functional characteristics and design considerations that need to be borne in mind when selecting the most suitable technological solution.

Learning Outcomes

By the end of this unit, students will be able to:

LO1 Explain the terminology used in construction technology

LO2 Describe the different techniques used to construct a range of substructures and superstructures, including their function and design selection criteria

LO3 Discuss different methods of dealing with site conditions to support building and infrastructure construction

LO4 Illustrate the supply and distribution of a range of building services and how they are accommodated within the building.
