a big thanks to everyone who responded, i really appreciate. my case is slightly different. every time i have had a better way to do it that i have suggested very politely and professionally (using sentences like "do you think..." or "you know! this is what comes to my mind. i will let you make the final call/decision"), i have been silently removed from the project, and someone else was handed over the task to redo again. please allow me to give two examples, which i believe will make my situation a little bit clearer.
EXAMPLE 1:
i am given a stormwater management task. senior wants me to calculate CN soil/ground cover data by tracing in CAD. i request to allow me to ponder over for a day, spend an entire weekend in the office (without charging), write my own code in .net to automate the entire calculation (from survey linework to CN values). step 1 done. aside from this, i ask the question about what regs to follow. the answers that i get raises suspicion. since i wanted to do my due diligence to the best extent, i call the state dep, the county etc, and get to the bottom of the regs we have to abide by (very different from the regs i was asked to follow). i put together a very polite yet professional email essentially summarizing my effort, mentioning that i have the ground work done, please recommend what the next steps should be and please make some decisions, and also suggested that we may want to get face to face with the regulators to get some clear answers on the "grey" areas of the regs. about a month later, i realize after over hearing a phone conversation that i have been cut off from this project, and another person is basically re-doing all the calculations (flows, volumes, water quality)from scratch. i decide to let it go (although i felt a little sad).
EXAMPLE 2:
project 2, surveyor gives survey at wrong geographic location. i am asked to move it myself to manipulate it into somewhat right location. i accept the task, but at the same time point out that this is somewhat of a liability issue, and also bring to attention what the expected projected coordinate system should be. i also seek clarification (again, very politely) if the survey scope asks the surveyor to deliver a DTM. this is a project where the precise locations are very important. i am shaky on locations because i moved/rotated the file myself to create the base file. moreover, i am asked to create DTM from the surveyor's contour. again, i accept the task politely, but do mention that creating DTM from contours may not be the best way, compared to creating from points/breaklines. two weeks later, i am in another project that involves hatching landscape areas in CAD.
i have gotten time and time again-
"we (as in this person and the near/dear ones) are going to take care of the design, and you can help us with....."
and to that, i have politely replied-
"i would be more than happy to do this for you, but please note that i believe i will be able to do these tasks more effectively if i have some idea of the design process (i am not blank on the design)"
please do not get me wrong, i would be more than happy to participate in every aspect of a project, and at the same time would want to learn something from each. i may sound like i am a bit anal and detail oriented, but that's just how i have learned about this profession in my engineering school: if i am not completely right, then i am wrong. and all i am doing is:
a. trying to come up with ideas to do my job faster and more efficiently, and
b. making the decision makers aware of all the aspects, and offering possible solutions.
now if anyone can share some insight and please suggest where i am going wrong, i would really appreciate. sorry to make everyone read this much, but wanted to sketch a clearer picture.
