Introduction
COST ESTIMATES A forecast of future project cost prepared to ensure success of project undertaking - particularly financial success.
COST ESTIMATES A basis for approving an economical and reasonable budget needed to complete the project on time with required quality. [Proponents and Owners]
COST ESTIMATES A basis for endorsing a realistic and reasonable budget acceptable to the owner without sacrificing public safety in compliance with codes & regulations [Designers]
COST ESTIMATES A basis for declaring BID PRICE that is acceptable to the client with reasonable profit. [Contractors]
COST ESTIMATES A basis for requesting BUDGET necessary to perform construction activities in conformance with quality and delivery requirement. [Project Engineers]
Purpose of Estimating and Costing
There are several purposes in estimating and costing --depending on point of view of-Proponents/Owners Designers Contractors Project Engineers
Proponents’/Owners’ Point of View To establish a reliable and dependable Cost Estimate that will serve as a basis for awarding the project to qualified contractor.
For proponents and owners with reliable and accurate estimate, Bid Price is gauge how close it is to reality of completing the project on time without sacrificing quality.
The objective of estimating is to declare the right budget for the project to be completed on time without sacrificing quality. A budget acceptable to contractors that is economical and reasonable.
Contractors’ Point of View To establish a realistic and accurate Price with greater chance of winning the bid and gaining reasonable profit.
Winning the project without gaining profit is a losing proposition. On the other hand, ensuring greater profit without winning the project is a futile exercise.
The objective of estimating is to declare the right price for each work item. A price acceptable to the client with reasonable profit.
Designers’ Point of View To establish alternative budget options that is realistic and acceptable to owners without sacrificing Public Safety.
For designers with realistic and reasonable estimate, Owner’s Budget is gauge how close it is to reality of ensuring Public Safety and complying Codes and Regulations.
The objective of estimating is to endorse the right budget for the project without sacrificing public safety and code compliance. A budget acceptable to owners that is realistic and reasonable.
Project Engineer’s Point of View To establish alternative budget options that is realistic and reasonable to company without sacrificing Quality and Delivery.
For engineers with realistic and accurate estimate, Company’s Budget is gauge how close it is to reality of ensuring the project will be completed on time without sacrificing quality.
The objective of estimating is to endorse the right budget for the project to be completed on time with the required quality. A budget acceptable to the company that is realistic and reasonable.
Importance of Detailed Costing
Importance of Detailed Costing DURING DESIGN & PLANNING STAGE Preliminary Cost Advice and Budgetary
For owners, knowing the budgetary requirement is a must. It is necessary for making a -GO or NO GO decision.
Importance of Detailed Costing DURING DESIGN & PLANNING STAGE Studying Possible Design Option
With costing in design options, the owner is able to study not only the quality behind… But also the cost implication for such option.
Importance of Detailed Costing DURING DESIGN & PLANNING STAGE Cost Planning
The management can plan for cost appropriation, if cost of work is clear. Budget approval would be easier --eventually.
Importance of Detailed Costing PRIOR TO CONSTRUCTION STAGE Basis for Pricing
For contractors, cost estimating is necessary in coming up with the most reasonable price with… greater chance of winning the bid and gaining good profit.
Importance of Detailed Costing DURING CONSTRUCTION STAGE Basis for Project Cost Control
With cost details, monitoring and control is easier to implement. Cost Performance Evaluation can be done quickly to assess savings or cost over run.
Importance of Detailed Costing DURING CONSTRUCTION STAGE Basis for Billing and Collection
Without Cost Estimates, billing would be unreliable. Worst, it might become unrealistic that the client will seek further justification.
Importance of Detailed Costing DURING CONSTRUCTION STAGE Basis for Evaluating Work Progress
In detailed costing, work items are declared with clear and definite costing per time interval. Time scaled costing serves as a basis for Progress Evaluation.
Importance of Detailed Costing DURING CONSTRUCTION STAGE Basis for Variation Claims
Change Orders and Extra Works have to be quantified and given costing prior to execution. Approved Detailed Costing is necessary before working.
Importance of Detailed Costing POST CONSTRUCTION STAGE Basis for Performance Analysis of the Project
After completing the project, final costing is done to reflect profit. The final cost becomes part of cost information needed as reference of future project.
Estimating Phases in a Project Cycle
Estimating Phases in a Project Cycle BUDGETARY ESTIMATE An owner’s quick estimate of Total Project Cost
It serves as a basis for sizing up whether financial standing is sufficient or not. Most appropriate during Conceptualization Stage.
Estimating Phases in a Project Cycle PROGRAMMING ESTIMATE An estimate of major work item in percent weight
It serves as a basis for cost allocation of major work items. Most appropriate during Project Definition Stage.
Estimating Phases in a Project Cycle SCHEMATIC ESTIMATE A designer’s estimate of major work items
Estimates are more accurate when material specifications and bill of quantities are known. Most appropriate during Project Planning Stage.
Estimating Phases in a Project Cycle PRELIMINARY ESTIMATE A contractor’s estimate of the project
An estimate that is focused on winning the bid and gaining profit. Most appropriate during Project Tendering Stage.
Estimating Phases in a Project Cycle FINAL ESTIMATE An optimum estimate from a bid winner
An estimate that is focused on establishing cost control as well as maximizing profit. Most appropriate during Pre-planning Stage.
Estimating Phases in a Project Cycle CONSTRUCTION ESTIMATE A construction estimate based on production plan
An estimate that is focused on optimizing resources, productivity and cost savings. Most appropriate during Project Execution Stage.
Steps in preparing Cost Estimates
Step #1
LEARN ABOUT THE PROPOSED PROJECT
Step #1
LEARN about the proposed project. BEGIN by fully understanding the Proposed Project Package.
Apply 5W2H.
First “W”
Stands for WHO? (Who is the owner of project?) Knowing the owner will give us an idea about the Proposed Project Package.
Owners have particular quality, delivery, and cost requirement.
Second “W”
Stands for WHAT? (What the project is all about?) A brief description that will give us an overview about the Proposed Project.
Details can be found in the Invitation to Bid and Scope of Work.
Third “W”
Stands for WHERE? (Where the project is located?) Be familiar with the location of the proposed project. Is it remote? Far? Is it Near? Accessible?
Some factors have to be considered based on project location.
Fourth “W”
Stands for WHEN? (When to submit the bid?) (When to start and finish the project?) Know the deadline in order to submit the bid on-time. Determine when to start and finish the proposed project.
Know the project schedule. When? What date? How long?
Fifth “W”
Stands for WHY? (Why undertake the project?) Unwritten most of the time. But, there is always a reason behind a project being done.
Knowing this hidden “WHY?” is a plus factor. It answers the quality, delivery and cost requirement.
First “H”
Stands for HOW? (How the project would be done?) Knowing “HOW” is... ...knowing the step-by-step work to be undertaken on the project.
Knowing the “STEP” is... …knowing the quality, delivery and cost component of the WORK.
Second “H”
Stands for HOW MUCH? (How much is the cost of the project?) Knowing how much... …is the approved budget… ... is a plus factor.
DECLARED OR NOT... …you must have an idea to make the estimate realistic.
5W2H WHO? WHAT? WHERE? WHEN? WHY? HOW? HOW MUCH?
5W2H WHO IS THE OWNER? WHAT? WHERE? WHEN? WHY? HOW? HOW MUCH?
5W2H WHO IS THE OWNER? WHAT IS THE PROJECT? WHERE? WHEN? WHY? HOW? HOW MUCH?
5W2H WHO IS THE OWNER? WHAT IS THE PROJECT? WHERE IT IS LOCATED? WHEN? WHY? HOW? HOW MUCH?
5W2H WHO IS THE OWNER? WHAT IS THE PROJECT? WHERE IT IS LOCATED? WHEN TO START/FINISH? WHY? HOW? HOW MUCH?
5W2H WHO IS THE OWNER? WHAT IS THE PROJECT? WHERE IT IS LOCATED? WHEN TO START/FINISH? WHY DO THE PROJECT? HOW? HOW MUCH?
5W2H WHO IS THE OWNER? WHAT IS THE PROJECT? WHERE IT IS LOCATED? WHEN TO START/FINISH? WHY DO THE PROJECT? HOW IS IT UNDERTAKEN? HOW MUCH?
5W2H WHO IS THE OWNER? WHAT IS THE PROJECT? WHERE IT IS LOCATED? WHEN TO START/FINISH? WHY DO THE PROJECT? HOW IS IT UNDERTAKEN? HOW MUCH IS THE COST?

Well experience Bidder could determine the
BEST BID. Having the maximum marked-up that could be inserted in a bid. The mark-up is usually based on mathematical computation as well as extra-sensory calculation focused on winning and gaining.
In conclusion
A BID WINNER Could release the right bid proposal, at the right price, at right time and place. Just like a martial art champion releasing the right strike at the right time at the right point.
