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
