What’s COSTES
• Road maintenance by Performance Based Contract (PBC)
2
• Cost Estmaton Manual for road Maintenance under Performance Based Contracts
Provide adequate cost estmaton of PBC
• Cost Estmaton Sofware (COSTES)
Series(2011,2015,2017,2019(planned))
Provide Easy and Quick Soluton to Cost Estmaton
COSTES Framework

1. Concept of COSTES 2015
• Less Input, Quicker Estmaton
• Three input method based on the road data collected by authorites/contractors
• Both Road authorites and Candidate Contractors can use this system

2. Quantty Calculaton in COSTES
6
Labor Price per month = Quantty of Labors per day * Workini days per month * Unit Price
3375000ksh=300 (Labors/day) *25 (days /month) * 450 (ksh/day)
Quantty of Labors per day = Productvity Rate * Quantty of the Contract
300 (Labors/day) = 0.3 (persons/ day / 1000m2 )* 100000 m2

Input Type Simple Quantty Input Actual Quantty Input
Input length only(Use km unit quantty)
Descripton Input entre quantty includini maintained area and non-maintained area
Input size of the maintained area
Input the lenith of the contract road(COSTES has unit q’ty)
Pros Accuracy is beter Accuracy is the best Need to input project lenith only
Cons Quantty inquiry is necessary
Precise quantty inquiry is necessary
Accuracy is unsure if road has unusual type

• See paie pp. introducton-15 of the PBC Manual
• If your road type is far from the imaies, collectni actual quantty (or simple quantty) is stronily recommended.
Risk: Low Estmaton
