Quantity Surveyor - Introduction 3
“A professional working within the construction industry concerned with building costs” Wikipedia
In USA known as Cost Engineer A specialist tradesman who prepares standardised schedules for a building project in which all of the construction materials, labour activities and the like are quantified. His prime task is to ensure that the project is kept within budget and that the client gets value for money Quantity Surveying & Estimation

History of QS 4
QS developed its root in UK during 17th century 1785--Earliest recorded firm, Henry Cooper and Sons of Reading was established 1820--Emerged as a profession, one of the earliest QSs was Sir Henry Arthur Hunt in Uk 1858--First recorded use of term “quantity surveyor” 1933--Institution of civil engineers, London published report on engineering quantities 1953--Standard method of measurement issued and being updated until today…………… Quantity Surveying & Estimation

Main Stages in Construction Project 5
1- Concept : identify the project needs, and objectives 2- Technical studies as feasibility study, possibility of implementation, primary cost, and possibility of financing etc. 3- Preliminary design 4- Detailed design including architectural , structural, electrical, mechanical. 5- Tender documents. 10- Preliminary handing over the project 6- Tendering 11- the operation of the project 7- Contract Award 12- maintenance period 8- Contract Agreement 13- Project final handing over 9- Starting Construction Quantity Surveying & Estimation

Traditional Role of a QS 8
Measurer – Arrives at quantities of different items of work for:
Tender document preparation (for developer)
Tender Pricing (for contractor)
Handles BOQ and prices schedules
Bills for payment, intermediate and final
Measures quantities from drawings and from site

TYPES OF QS 9
Professional Quantity Surveyor Broadly concerned with contracts and costs on construction projects. The methods employed, however, cover a range of activities which may include cost planning, value management, feasibility study, cost benefit analysis, lifecycle costing, tendering, valuation, change control, dispute resolution and cost estimation. Contractors Quantity Surveyor A contractor's QS is responsible for the performance of operations that mirror those of the owner's QS; i.e., the measurement and pricing of construction work, but specifically performed by the contractor as opposed to the construction work described and measured in the construction contract between the developer and the contractor.

Changing Role of a QS 10
Costs have become more dynamic, changes are faster. Technology change, mechanization. From primary civil engineering to a mix of mechanical & electrical, plumbing, fire protection etc.... Corresponding to change from single & double storey construction to multi-storey complexes. Energy costs and environmental requirements. Energy Costs have also brought in change to the architectural design of buildings. Quantity Surveying & Estimation

Changing Role of a QS 11
We can no longer overlook the operating cost of the building as a whole. Our building designs should keep energy in all its forms and stages of utilisation. Speed of construction is now of assuming importance. With the gradual but continuous increase in labour costs it is essential that the design is such that the requirements of resources is kept to a minimum.

Today’s Requirements 12
So what is, a QS required to know in today’s
fast moving world?
Basic civil work processes and costings. Component materials. Material and equipment selection and effect on costs. Building operation costs based on Energy efficiency, Environmental effects and maintainability. Quantity Surveying & Estimation
