Appendix 3: Cost Estimation Data

A. Numbers of Facilities

The following table shows the data collected on the numbers of facilities of each facility group. Generally, this data is collected from the 2002 US Economic Census for private facilities and the Census of Employment and Wages for public facilities. The number of state and local judicial and detention facilities is estimated from the total number of public order and safety buildings, reported by the Energy Information Administration (EIA), 2003 Commercial Buildings Energy Consumption Survey. The number of office buildings is also collected by this EIA survey. Data for all facilities were adjusted to estimates for 2007 using growth rates from the May 2007 McGraw-Hill Dodge Construction Potentials Bulletin.

B. Annual Growth Rates of Facilities

The following table lists the rates of new construction for each facility group. These are determined from the May 2007 Dodge Construction Potentials Bulletin, which counts the number of new construction and major alteration projects for certain facility types. These projects are compared to the data on existing numbers of buildings to determine a growth rate per facility type. If no data is collected on the new construction data, a 1% growth rate is assumed. Facilities which posted growth rates greater than 1.2% were assumed not to be able to sustain such high rates of growth for 15 consecutive years and growth was capped at 1.2%. It is assumed that public facilities have the same growth rate as their counterparts in the private sector.

C. Assumptions With Respect to Estimated Typical Facility Size

This table is compiled with the Department's architects' assumptions on the typical facility size of each facility grouping in order to determine the estimated number of elements per facility. These assumptions were reviewed by the Cost RAP panelists.

F. Likelihood of Element in a Typical Facility

This table represents the Cost RAP panelists' assumptions and HDR's assumptions on the likelihood that a typical individual facility will have each element and will be affected by the incremental change to the requirement. For example, it is assumed that large facilities such as stadiums will be affected by the requirement for public entrances and that 25% of all stadiums are large enough to have the number of public entrance doors that will be affected by the change.

The high and low values that create the range of the likelihood are plus and minus 10 percentage points of the most likely values if the most likely value is less than 50% or plus and minus 20 percentage points of the most likely values if the most likely value is greater than or equal to 50%.

Requirement	Conditions for change	Likelihood that Element at Facility AND Subject to Change for Compliance
1-Public Entrances	Large newly constructed facility (e.g., arenas, stadiums, convention centers, and shopping malls) will have multiple doors intended to be used as public entrances/exits.	25%
2-Maneuvering Clearance or Standby Power for Automatic Doors	Facility (a) with an occupant load of less than 50 persons (b) installs an in-swinging automatic door that serves as part of an accessible means of egress. Some of these small facilities may simply choose not to install an automatic door.	10%
3-Automatic Door Break-Out Openings	Facility (a) installs an automatic door that serves as part of a means of egress (b) that does not have standby power and (c) there are no manual swinging doors serving the same means of egress.	50%
4-Thresholds at Doorways	Newly constructed facility has exterior sliding doors that are part of an accessible route.	50%
5-Door and Gate Surfaces	Newly constructed facility has swinging doors or gates. Most new doors meet the requirement (but not gates.)	25%
6-Location of Accessible Routes	Facility is designed in such a way that it has a colorable claim that it is infeasible to locate the accessible route in the same area as the circulation path, but will now have to do it anyway.	10%
7-Common Use Circulation Paths in Employee Work Areas	Facility is or was designed to have common use circulation paths in employee work areas that do not overlap or serve as an exit for common use areas (such as employee toilet or locker rooms, break rooms, kitchenettes). Several exceptions exempt common use circulation paths in employee work areas where it may be difficult to comply with the technical requirements for accessible routes due to the size or function of the area.	10%
8-Accessible Means of Egress	The current guidelines require the same number of accessible means of egress to be provided as the number of exits required by applicable building and fire codes.	10%
9-Stairs (NC)	Facility plans to install an elevator. (Assumed for all facilities with three or more stories.)	90%
10-Stairs (ALT/BR)	Facility has an elevator. (For Alt, assumed for all facilities with three or more stories.)	5%
11-Handrails Along Walkways	Facility chooses to install or replace handrails on non-ramp walkways, and the handrails do not comply. Such handrails are not common.	10%
12-Handrails	Facility has handrails (e.g., on ramps, non-ramp walkways, or stairs).	50%
13-Accessible Routes from Site Arrival Points and Within Sites	For NC, facility would not construct a pedestrian route but for the current requirement. For Alt, facility has or constructs a sidewalk.	80%
14-Standby Power for Platform Lifts	Facility has or will install a platform lift as part of an accessible means of egress. The revision will primarily affect newly constructed performing arts centers and auditoriums that use platform lifts to provide an accessible route to the stage. Platform lifts are rarely used in the other places permitted in new construction. For alterations and barrier removal, will only apply to platform lifts permitted to be used as part of an accessible means of egress as required under the current rule.	50%
15-Power-Operated Doors for Platform Lifts	Facility has or installs a platform lift that (a) either serves more than two landings (small %) or does not have doors on opposite sides (requires side entrance) and (b) has sufficient maneuvering clearance. Platform lifts typically serve only one or two landings and have self-closing manual doors on both ends.	20%

G. Likelihood of Element in a Typical Facility (Varying by Facility)

For some requirements, the likelihood of an element at a facility and subject to change in order to become compliant under the Rule is assumed to vary by the type of facility (hotel versus store, etc.) These likelihoods also have a "most likely" value, as well as high and low values which are equal to plus and minus 5% of the most likely likelihood value.

The most likely value is presented in the table below; conditions for the likelihood are shown separately at the end of this table. The facility-requirement matches labeled as N/A represent that the requirement is not typically present in the facility, so the likelihood that a facility would have the element to comply does not apply.

The publicly owned counterparts of the facilities below generally are assumed to have an equal likelihood of an element both existing and requiring change to bring it into compliance with 2004 ADAAG (or other alternate baseline). However, the likelihood of change for the requirements for accessible means of entry to swimming pools (Req. ## 79 & 112), accessible saunas and steam rooms (Req. ## 72 & 111), and play areas (Req. ## 99-104) at public (Title II) facilities in this Appendix take into account estimates of pre-existing compliance (or, in the case of new construction or alterations, projected compliance) with 2004 ADAAG due to overlapping program access requirements. See Section 2.4.1. First, for public aquatic centers / swimming pools, the likelihood that an accessible means of entry would need to be added (via lift or sloped entry) in order to comply with 2004 ADAAG was reduced by 73% based on sources cited in the Access Board's regulatory assessment for recreational facilities that about 70% of existing pools already provide one or more accessible means of pool entry. Id. Second, for saunas and steam rooms, this same percentage (73%) was used to scale back the likelihood for change both because saunas and steams rooms are frequently co-located with swimming pools at recreational facilities (and thus are assumed to share common accessibility levels and features) and because no public survey data exists for saunas. Third, a series of recently published surveys of play areas at large urban parks and school districts nationwide showed that the vast majority of existing play areas at these facilities, as well as play areas expected to be constructed or renovated over a five-tear planning horizon through 2011, already use (or plan to use) accessible surface materials that are compliant with 2004 ADAAG. See "Playgrounds in the Nation's Largest Urban Park Districts," Henderson Consulting Services, Inc. (March 2006); "Playgrounds in the Nation's Largest School Districts," Henderson Consulting Services, Inc. (March 2006) (both surveys available at http://www.fibar.com/Playgrounds/news.htm). Based on this survey data, the likelihoods for change for public play areas was scaled back by 50% for play areas built since 1992 (when the current ADA Standards for new construction took effect), and 25% for play areas built prior to 1992.
