Project level budgetsTurnover projections
–Based on information available•Low level of information- s curve models•High levels of information- price and programme analysis
•Production budgets–Procurement budgets
•Labour•Materials•Plant•Subcontractors
–Activity level budgets•Used to monitor the productivity of the resources•Labour outputs•Materials wastage•Plant utilisation•Etc.

Subcontract procurement budgets•Subcontract packaged send outs•Quotations received and assessed for compliance•Comparisons made•Quote selected for inclusion•Discount taken?•Adjustment for commercial opportunity•Budget and procurement programme established•Resend outs•E-procurement–Reverse auctions

Budgetary control•Control- implies an ability to influence outcomes
–Budgets established based on “theoretical“ conditions expressed within the documentation.–Often little relationship to actual conditions, can give rise to an argument for rerating however most “control” attempts to bring future events closer to those predicted.
•Resource allowances–From the net allowance bill–Adjustments for additional oncost to provide targets loosely based on estimators assumptions
•Basis principle–Disentangle procurement gains from production losses–e.g. if labour costs £10.00/hr and the allowance is £12.00/hr, this is a buying gain and should not mask losses which may be due to low productivity
•Control strategies–Labour
•Labour allocation sheets•Bonus development
–Materials•Wastage•Contra charge subcontractors for over-use
–Subcontract•Reconsider construction sequence/re-engineer design•Seek new prices

Earned Value Analysis
•EVA- compares the amount planned with that accomplished to determine if cost and programme are as planned.
•Projects subdivided into work breakdown structures (each with control plans)
–BCWP Budgeted cost of work performed
–BCWS Budgeted cost of work scheduled
–ACWP Actual cost of work performed

Derived metrics
•CPI-cost performance index–CPI=BCWP/ACWP
•SPI-Schedule performance index–CPI=BCWP/BCWS

EVA in construction practice?•Challenges
–Unique nature of projects–Difficulty in establishing work breakdown structures–Impossible to develop control plans
•Information–Historical benchmark data out of date v quickly
•New technologies•Different approaches to activity that make comparison spurious•Data collection and analysis costly
•Integration with CVR–Has been attempted but the systems are designed for distinctly different purposes
•CVR-accounting•EVA-production
•Future–BIM possibilities....
