The research team assembled data on state-ofpractice cost estimating and cost estimate management techniques, including process steps and tools in relation to the project development phases presented in Chapter 1. Literature Review The objective was to identify documented practices in the area of cost estimation and cost estimate management specifically relevant to the ROW component of project development.

From page 203... ...
ROW cost estimation is a complex undertaking dependent on a magnitude of parameters that are difficult to quantify, even in the case of an identifiable date only a few years in the future. ROW cost estimates must capture all costs that affect the expense of acquiring the needed property.
|
From page 204... ...
Similarly, the quality of available information can have a negative effect on the estimate because the estimate can only be as accurate as the information upon which it is based. In an attempt to improve ROW cost estimates, several tools and models for ROW cost estimation have been developed.

Appraisal and acquisition methods must be understood by those who prepare ROW cost estimates. The appraisal and acquisition methods should be integrated into the overall project development process.

From page 206... ...
Section 5 of the protocol focused on how differences were reconciled between estimates, the procedures for handling changes in ROW requirements, and triggers for an update to ROW cost estimates. The effect of state laws and other factors such as environmental, political, and social issues on the ROW process and estimates were addressed in Section 6.

It was necessary to acquire in-depth information about the cost estimation process that included some elaboration and explanation on the part of the interview participants. Onsite interviews provided the opportunity to clearly communicate specifics about the process and provide the detail necessary for developing the ROW cost estimation and cost estimate management flowcharts.

This served to give the research team a basis for further questions and to relate participant answers to project development phases (planning, programming, preliminary design, and final design)
|
From page 209... ...
Shortly following the interview, an interview report was prepared which consisted of filling out the protocol based on the interview notes. This allowed the team to capture and understand the process for ROW cost estimation and cost estimate management used by the SHAs throughout all phases of project development.

Risk Analysis and Assigned Contingency The majority of agencies interviewed made no attempt to conduct a formal detailed risk analysis of items that could affect ROW cost, although most agencies did assign contingency amounts in some manner. A detailed risk analysis can be defined as a systematic method of identifying and evaluating risks using a formalized agency procedure.

the absence of effective tools and methods to complete ROW cost estimates. ROW estimates made during the planning phase of project development are often based solely on a percentage of estimated construction costs.
|
From page 212... ...
In the case of most SHAs, the ROW division or group will receive a request from the project manager for a ROW cost estimate. This request is often accompanied by an aerial map or other visual representation of the project site with approximate ROW boundaries indicated.

From page 213... ...
If the condemnation rate is estimated accurately, the cost of condemnations will usually be accurate because they are primarily based on state laws. General ROW Cost Estimating Practices During Preliminary Design At the preliminary design phase of project development, the ROW cost estimate is further refined.

From page 214... ...
Again, a cost estimate sheet is used in producing the estimate to ensure that all aspects of ROW cost are included in the estimate. The same line items included in the programming estimate sheet are examined for this estimate but now are examined in more detail (e.g., parcel information should be available by this point in project development)

All states have a defined process for condemnation proceedings and, depending on the state, condemnation actions can delay project construction starts. E-14 Procedures Guide for Right-of-Way Cost Estimation and Cost Management
