The $789-billion economic stimulus package passed by the House and Senate Appropriations Committee on Friday includes an estimated $131 billion for construction-related spending. A more precise number can’t be determined because some capital-spending funding in the bill can be used to purchase equipment as well as to fund construction–transit is one example, according to Engineering News Record.
There was no specific line item for school construction but states could use school stabilization allotments on school modernization. $39.5 billion of the bill’s $53.6-billion State Fiscal Stabilization Fund would go to local school districts.

A more detailed breakdown by sector is at ENR:

Transportation  - $49.3 Billion

Defense/Veterans - $7.78 Billion

Housing/HUD - $9.6 Billion

Schools - No specific line item, but $39.5 billion of the bill’s $53.6-billion state fiscal stabilization fund would go to local school districts, and school modernization would be one of several eligible uses for that $39.5 billion.

Energy - $30.62 Billion

Government Buildings - $13.365 Billion

Water and Environment - $20.1 Billion
