This document discusses project execution and contracting. It explains that large projects are normally contracted out, while small projects may be done in-house. Medium projects can be a mix of contracting and in-house work. Statutory approvals are required before project execution. Contracts must satisfy elements like offer/acceptance and consideration to be valid. Turnkey contracts assign all responsibility to the contractor, while non-turnkey contracts divide the work into packages contracted separately. Tenders are used to solicit bids from contractors in a transparent manner.
