Struktur bangunan harus dalam kondisi baik dan memenuhi kriteria kelaikan teknis. Masjid Apung Ziadat-ul-Abror di Pantai Pagatan Kabupaten Tanah Bumbu Kalimantan Selatan yang dinisiasi dan dibangun oleh PT. Borneo Indobara diharapkan akan menjadi daya Tarik bagi wisata religi di Tanah Bumbu. Selain aspek keamanan, aspek kenyamanan bagi pengguna harus menjadi perhatian. Pemeriksaan pemenuhan standar getaran menjadi salah datu bagian yang harus dilakukan untuk menjamin jamaah merasa aman dan nyaman saat beribadah di dalam masjid. Hal tersebut sejalan dengan yang diputuskan dalam Keputusan Menteri Negara Lingkungan Hidup No.49 Tahun 1996 dan yang diatur oleh ISO 2631-2 1989 yang mensyaratkan getaran yang tidak merusak bangunan, mengganggu kenyamanan dan kesehatan manusia. Dari hasil uji getar diketahui bahwa getaran pada kondisi operasional masih dalam batas yang diijinkan dengan frekuensi antara 5,66-15,86 Hz, percepatan getaran puncak 0,36-1,94 %g, kecepatan getaran puncak 0,10-1.99 mm/det dan lendutan dinamik 1,22-67.37 mm.
