Do you mean "insured" instead of "insurer?"

Each prime contractor and their subs are required to obtain and maintain their own insurance per 52.228-5 Insurance-Work on a Government Installation per whatever types and coverages are specified in the construction contract.

In addition, 52.236-8 Other Contracts, should also be included in each contract.

I reworded this question: Can a Prime General Contractor (GC) for Construction request, other contractors that are also working simultaneously in the space on support of the same project (i.e. separate work packages, such as furniture or IT items, (so NOT direct subcontractors to the Prime General Contractor)) to add the Prime General Contractor as an additional insurer on the separate Certificate of Insurance's of each of the non-direct contractors that are also doing work in the space?

So you want to add other contractors to your policies, as insured parties under your policy?

There is no contractual relationship between the separate contractors on a site or between the GC and their subs. I’d say that this couldn’t be done to fulfill another contractor’s contractual responsibility or their sub’s responsibility to provide insurance.

Why would casualty insurance companies agree to insure other parties under your policies? The GC has no control,  supervision or overarching accident prevention program for other parties.
