This phrase, "assisting delivery of construction programs", is not grammatically correct.
One would normally use is or with, and either with or without an article:
- "assisting in the delivery of construction programs";
- "assisting with the delivery of construction programs"; or
- "assisting in delivery of construction programs"
- "assisting with delivery of construction programs"
I would consider the formulation using in the or with the as normal grammar, but just using in or with is also quite common in a list such as might appear in a CV.
What sometimes happens is that articles and prepositions are dropped in lists such as these (e.g. in CVs) either to save a little on space or, what seems to be more common, to sound punchier.
What this leads to is, when someone writes their skills or responsibilities in a list in their CV, that they [may] start with:
One of my responsibilities was assisting in the delivery of construction programs.
This becomes a list item such as:
- assisting in the delivery of construction programs
which then is edited to remove all the "unnecessary" words and perhaps sound more dynamic:
- assisting delivery of construction programs
