Estimates for construction of recommendations were developed to complement the Plan. They were developed by identifying pay items and establishing rough per-mile quantities. Unit costs are based on 2013 dollars and were assigned based on historical cost data from the NCDOT, the UNC-Chapel Hill Highway Safety Research Center – Costs for Pedestrian and Bicyclist Infrastructure Improvements Report, the Town and other sources such as RS Means, a leading source of construction cost information. The costs shown only reflect cost associated with construction of the particular bicycle facility indicated and do not reflect other costs that may be associated with a larger project. The costs are intended to be general and used for long-range planning purposes. A 10-30% contingency is applied to the cost for each item based on the scale of the project. For example:
- 10% contingency applied to signed bicycle routes and shared lane marking projects as they are relatively straightforward.
- 20% contingency applied to projects which add bicycle facilities through such actions as lane diets, road diets or projects which fix existing infrastructure.
- 30% contingency is applied to projects which require substantial construction efforts such as widening roadways, construction of greenways or sidepaths or the installation of lighting.
- No contingency is applied to bridge projects as these estimates are based on historical pricing for bridges on a square foot basis.
The construction estimates do not include costs for planning, surveying, engineering design, right-of-way acquisition, complete edge to edge roadway reconstruction, addition of closed drainage systems, mobilization or future maintenance. Construction costs will vary based on the ultimate project scope (i.e. combination with other projects) and economic conditions at the time of construction.
The costs for intersection study, bicycle channels and ramps are approximations to aid in setting budgets. The materials likely to be utilized and the method of construction for bicycle channels and ramps varies greatly from location to location.
The following tables provide the assumptions utilized to calculate the probable construction cost for each potential bicycle network project. The tables identify the facility type with the corresponding implementation action. An example is:
Facility Type (Action) –> Sharrows, SH (Add Markings, AM)
Cost are calculated on a per mile basis and applied to the actual project mileage on the UNC_CH Summary Table. The Item Costs are also shown on the individual Project Descriptions in Appendix D. Exceptions to this approach include the following which are listed under the “Other Projects” category:
- William Blythe Drive because it only recommends the addition of bicycle lanes through existing lane narrowing.
- Bicycle stair channel and bicycle ramp retrofits which are shown on the short term map and described in Chapter 3.
- Intersection study recommendations which are shown on the short term map and described in Chapter 3.
- Development of a signed route system throughout campus as described in Chapter 3 and shown on primary and secondary bicycle route map shown in Chapter 3.
