My survey, Can you help please ?

Apologise in advance for disturbing, I'm a final year Quantity Surveying student, currently conducting a survey with regards to the title of "Analysis of contributory factors of skills shortages  in construction project delays & cost overrun" for my dissertation. Please take some time to respond to my questionnaire. I would appreciate your participation and assist in this survey. Thank you.
