Explore variations in construction projects and master the full variation procedure from basics to advanced, including sources, identification, negotiation, and real-time variation claims.
Explore how variations modify original scope, cost, and time in construction projects. Learn conditions that trigger changes, such as material availability, quality, technology, disasters, and design revisions.
Identify employer-related variations in construction projects, including plan or scope modifications, financial constraints, material or procedure substitutions, decision delays, and specification updates.
As a quantity surveyor, you are visiting the site and find a difference between the drawings and executed work in the site, what will you do?
Learn how contract documents define roles, responsibilities, and the variation process. Recognize drawings, specifications, construction programs, quality management plan, health and safety plan, and risk controls guiding changes.
Based on your experience, if there is a quantity discrepancy between the drawing and the BOQ?
1)Which document takes priority?
2)What will you do to confirm the quantity?
Understand the procedure of variations in construction projects, from engineer's request for proposal to contractor written response, detailing scope of work, quantity and cost, execution program, evaluation, and approval timelines.
Learn how a formal instruction to proceed additional work is issued, assessed as variation or extra work, with appended documents, notices within 14 days, and potential payment or schedule implications.
This lecture explains how variation claims fail when contract procedures are not followed, including notifying the client, submitting approved drawings, and reasons for rejecting a Jersey barrier variation.
Explore extension of time concepts for project delays caused by variations, and how clients and contractors assess time impact, reference documents, and cost implications under the contract.
Extract measurements from AutoCAD drawings using the key plan and sketch, identify security fences and priorities, and transfer lengths to Excel for priority one and two.
Learn to quantify road works by calculating cutting and filling from drawings and extracting existing and proposed ground levels to compute C1 coat and 50 mm bituminous asphalt quantities.
Learn to derive unit rates for construction variations by analyzing dri and selling costs, referencing the bill of quantities, and breaking down walls, foundations, and finishes for pricing.
Construction Variations for Quantity Surveyors is a practical course covering the complete construction variation process, from identifying a change through measurement, pricing, submission, negotiation and approval.
The course is designed for Quantity Surveyors, Assistant Quantity Surveyors, Estimators, Civil Engineers, Cost Engineers and construction professionals who want to understand how variations are managed on real construction projects.
You will learn how to:
Identify construction variations and change orders
Understand the Quantity Surveyor's role in variation management
Review construction drawings and identify changes in scope
Prepare variation notices and contractor correspondence
Measure and quantify varied works
Prepare quantity takeoffs and BOQs
Carry out rate analysis and variation pricing
Prepare cost proposals and variation quotations
Manage variations using Excel spreadsheets
Understand variation submission, negotiation and approval
Maintain variation records for commercial and cost control
Follow a practical variation from identification to final valuation
Practical Construction Variation Case Study
The course includes a practical infrastructure variation case study involving the relocation and lowering of existing MV cables.
You will work through the actual QS process:
Identify Variation → Contractor Letter → Client Response → Review Drawing → Measure Quantities → Check Rates → Prepare BOQ & Cost → Submit Variation
This practical approach helps you understand not only what a construction variation is, but how a Quantity Surveyor actually manages one on a project.
