Description
Description/ responsibilities:
Phase 3 of D.C.Tillman WWRP involved the modificationof 10existing Aeration Tanks (215' x
45' x 20'). Each tank requireddemo of the existing aeration system and installation of the new
aeration system.
The aeration system consisted of 4" PVC pipes with varying number of diffuser heads.The
diffuser heads used were either ceramic discs or rubber membranes. I was solely responsible
for the entire layout of the diffusers and the diffuser supports inthe field and making sure that
the operation was carried on as scheduled. Iwas also responsible for ordering and procuring
the right quantity of materials required ensuring scheduled progress of the project.
The pressurized air was fed to the new aeration system by varying sizes of stainless steel pipes.
Iwas responsible for the layout of the stainless steel pipe,the core through the walls and the
pipe supports. Iwas also responsible for ordering the precise quantity of pipe lengths and the
quality checks when the pipes arrived on site.
Apart from these responsibilities, Itracked and reported 1800 MH to my Superintendent and
Project Manager. Ialso designed and created work plansfor the craft crew to ensure precise
and accurate flow of work. Ialso made regular, routine checks in the site and the areas where
the craft men work to ensure strict conformance to safety procedures is followed and
maintained. Ihave also used Google Sketchup and Quickpen Pipe-Designer 3D to make sure
that there are no interferences inthe pipingand that the progress of the project is as
scheduled/planned. The mentioned softwares proved to be useful in making workplans for the
craftsmen as well.
