CMHA has contracted with ARA (the developer and owner of the software application), to provide technical assistance to licensees. Technical assistance is available through several means, including telephone, e-mail, and the internet. This technical assistance will be limited to operation and direct application of the software program and provides for telephone access to ARA staff between the hours of 9:00 a.m. and 5:00 p.m. (Eastern Time), Mondays through Fridays except recognized holidays.

Technical assistance includes assisting the designated licensee's user to properly install the product, to determine if there are any problems with the supplied program or documentation, and to provide general guidance in the use of the program and documentation. This technical assistance service is limited to the maximum of the hours of consultation and separate contacts initiated by the licensee's designated user during the first 60 days after receipt of the product materials, as listed in the table below. Callback telephone calls or other such contacts will not be counted against the limit of the contacts.

Technical assistance does not include any support related to interpretation or application of any edition of the AASHTO Guide for Design of Pavement Structures or Drainage Requirements in Pavements, nor does it include any support related to difficulties encountered by the licensee in attempting to modify the program. These services are considered totally outside the scope of this license agreement. The licensee may contact ARA for such services under a separate contract and fee arrangement, which is agreed, will not involve or obligate CMHA in any way.
