Construction Technology And Law Flashcards
What is the primary purpose of a site investigation?
To gather information about the physical, chemical, and geological conditions of a site.
What is one key outcome of a feasibility study?
Determining whether a project can be successfully completed within the proposed timeline and budget.
What is soil investigation?
Soil investigation is the process of exploring and analyzing soil properties to determine its suitability for construction or agricultural purposes.
What is the primary purpose of soil sampling?
To obtain representative soil samples for testing and analysis.
What does the term ‘soil permeability’ refer to?
The ability of soil to transmit water through its pores.
What is a geotechnical report?
A document that summarizes the findings of soil investigations and provides recommendations for construction.
What is the role of soil compaction in construction?
To increase soil density and stability, reducing settlement and improving load-bearing capacity.
What is the difference between cohesive and non-cohesive soils?
Cohesive soils, like clay, stick together, while non-cohesive soils, like sand, do not.
What is land registry ?
A record of information from the council stating the ownership of a piece of land or property. Land registry registers land in England and wales
What are title deeds ?
Title deeds are a series of documents that prove ownership of a property and the history of its ownership. (Lease information)

Freehold - this is a property that you own with no fixed time limit. You are responsible for maintenance on the land
Leasehold - this is a property that is purchased to live in for a set time period (e.g 800 years) may be subject to ground rent and service costs.
What are three types of contracts
Cost plus contracts - an agreement to reimburse a company for expenses plus a significant amount of profit
Design and build - where a contractor is in charge of designing and building the project
Lump sum contracts - where work is agreed to be carried out for a specific sum
What are the types of soils ?
Clay - 0.002mm - 0.063mm, impermeable (holds lots of water)
Silt - 0.063mm - 2mm, is fine mud Carried by rivers and seas (had a low bearing capacity)
Sand - 0.063mm - 2mm, can be easily washed away
Gravel 6.3mm - 63mm, strong, permeable (water runs through it)
Chalk - solid, strong but can contain fissures. Very hard to dig
Rock - solid, strong and very high bearing capacity. (Sandstone, slate and granite)
Peat - organic material made by decaying plants, very sponges can’t be built on
Pebbles - 63mm - 200mm
Boulders - 200mm - 630mm
What is a sustainable urban drainage system (SUDS) ?
A SUDS is a drainage system that mimics natural drainage processes. Used to transport surface water and slow run off before it enters watercourses. Done by draining into the earth or evaporated naturally
