    Havo sifati muhandisning mahalliy atrof-muhit bo'yicha mutaxassisi tomonidan ob'ektga tashrif buyurish paytida vizual kuzatish orqali baholandi. Tuproq ishlari paytida changning paydo bo'lishi atrof-muhitga katta ta'sir ko'rsatadi. Havo haroratining ko'tarilishi hozirgi vaqtda Pudratchi balansida bo'lgan mavjud yo'lda changning ko'payishiga olib keldi. Yo‘l-qurilish ishlari olib borilayotgan hududlarda changga qarshi chora-tadbirlar amalga oshirilmoqda. Shu munosabat bilan pudratchiga ertalab soat 7:00 dan kechki 19:00 ga qadar qurilish ob’ektlarida yo‘lni, jumladan, yo‘l chetlarini purkash intensivligini oshirish bo‘yicha topshiriq berildi. Ayni paytda bu vazifani bajarish uchun to‘rtta sug‘orish mashinasi ajratilib, ularning har biri kuniga 4-5 martadan sug‘orilmoqda.

     Shovqin darajasini o'lchash laboratoriyasining protokollaridan ko'rsatilgan ma'lumotlar shuni ko'rsatadiki, ishlaydigan qurilish mexanizmlaridan shovqin darajasi barcha o'lchash nuqtalarida davlat standarti va IFC standartining MPL (80 dBa) dan oshmaydi. Binobarin, ular ishlaydigan xodimlarning sog'lig'iga salbiy ta'sir ko'rsatmaydi.

     Qurilish bosqichining barcha bosqichlariga taalluqli boʻlgan oʻzbek milliy qurilish shovqin normalari KMK 2.01.08-96 “Shovqindan himoya qilish toʻgʻrisida”gi qonunida nazarda tutilgan va quyidagi 14-jadvalda batafsil bayon etilgan.

     Aholi punktlari bo'ylab qurilish ob'ektlarida vibratsiya darajasini o'lchash amalga oshirildi. Tebranish tezlashuvi nuqtai nazaridan, o'lchov nuqtalarida qayd etilgan 95 dB tebranish tezlashuvining ruxsat etilgan ekvivalent darajasidan oshmaydi. Ko'rsatilgan nuqtalardagi barcha o'lchovlar noyabr oyida 37-50 dB oralig'ida o'lchov protokollari bilan qayd etilgan. Vibratsiyani tezlashtirish darajasining ushbu qiymatlari atrof-muhitga ham, saytdagi xodimlarning sog'lig'iga ham salbiy ta'sir ko'rsatmasligini ko'rsatadi.
