areas where the literacy rate is low, congregations may arrange to use Kingdom Halls to conduct literacy classes, which non-Witnesses may also attend. Weddings Kingdom Halls may be used for wedding ceremonies of Witness-baptized couples. A couple sends a request in writing to the congregation's "service committee", which assesses whether the couple is "in good standing, living in harmony with Bible principles and Jehovah’s righteous standards" and that they approve of the members of the couple's wedding party, the groomsmen and bridesmaids. Jehovah's Witnesses attach no special significance to a Kingdom Hall wedding over a secular service. Witness couples may choose to be married elsewhere for personal or practical reasons. Kingdom Halls are not used for wedding receptions or other social events. Funerals Funeral services may be held in a Kingdom Hall if the body of elders considers that "the deceased had a clean reputation and was a member of the congregation or the minor child of a member". The family of the deceased may ask any respected male member of the congregation to conduct the service, which involves a simple Bible-based discourse. Depending on family preference and local custom, a Kingdom Hall funeral may or may not have the casketed deceased present. Disaster relief Disaster relief efforts of Jehovah's Witnesses are typically channeled through permanent local Disaster Relief Committees under the various branch offices, and are staged at Kingdom Halls and Assembly Halls as close as practical to the disaster area. Construction The construction crews of Kingdom Halls and larger Assembly Halls consist of volunteering Jehovah's Witnesses, sometimes from other countries, who have been pre-approved for work on construction sites. Witnesses in many countries use a number of standard designs for construction that can be built in just a few days. The act of constructing a Kingdom Hall in this manner is called a quick-build, although typically the preparation work involving the structural foundation and surrounding surface may take several weeks prior to the scheduled build. For various reasons, not all Kingdom Halls are constructed as quick-builds or using the standard designs. However, a noticeably dominant architectural style of Kingdom Halls is often used based on standardized design concepts and models, depending on needs. A Kingdom Hall or Assembly Hall may originate from the renovation of an existing structure, such as a theater or non-Witness house of worship. In areas of repeated or reputed vandalism, particularly in cities, some
