English to Russian Tech/Engineering Construction / Civil Engineering Temporary site facilities

Добрый день!

Прошу помочь с подбором варианта для "secondary benchmarks".
Контекст:
"Temporary SITE facilities costs are deemed to include all SUBCONTRACTOR's costs for the supply, installation and dismantling of the SUBCONTRACTOR's temporary facilities (excluding camp) such as, but not limited to:
■ site furnished offices,
■ personnel and goods transportation (vehicles and relevant running costs),
■ equipped warehouse and storage areas,
■ fabrication and maintenance workshops,
■ temporary networks (electricity, industrial water, drinking water, air, sewers, telecommunications, etc.),
■ secondary benchmarks necessary to set up of the works,
■ canteen facilities...."

Это часть договора субподряда, тематика - нефтегазоносные месторождения.

Спасибо!
