Look ahead…
Disaster Recovery
Special form of construction Public welfare is primary objective Speed of response is essential
Life safety Public services
Requires public & private cooperation Special contracting rules apply
Disaster Scenarios…
Natural disasters Hurricane Floods – Tidal wave - Tsunami Earthquake Fire
Man-made disasters Building collapse Fire Terrorist attack Unknowns… train wreck, hazmat spill, etc.
Key Systems
Infrastructure is essential for modern life as we know it
Life safety a priority
Sanitary systems
Hospitals, schools, & social systems
Electrical systems…
Water systems…
Debris…
Key Facilities…
Roads & Bridges…
Ports & Harbors…
Fire damage…
Terrorist actions…
Unknowns…
Recovery Operations…
Speed is essential Projects are spread out over wide area Work sites not well defined No plans & specs Organization and prioritization are key Scope limited to restore minimum operations Quality judged on speed & quantity Safety is paramount Logistics may be very complicated Contracts not well defined

Report from Gulf Oil Spill…
Centralized control is essential Numerous gov’t agencies involved Numerous non-govt agencies involved
Projects must be organized Projects must be prioritized Budget control is essential Speed is essential Media coverage increases pressures

Construction Goals Differ…
Life saving & emergency operations first Remove obstacles & hazards to life Enable key government functions Operate hospitals & schools
Restore utilities; elec, water, sewer Restore transportation; roads, bridges, rail Enable logistical functions; food, fuel, ice
Clear debris Restore normal operations Restore public safety & confidence
“Traditional” Contracts
Contracting operations…
Letter contracts Cost plus contracts Unit price contracts Indefinite quantity contracts Design-build contracts Design contracts Fixed price contracts
Construction contracts… Lump-sum Unit-price (pre negociated) Fixed-price with incentives
Cost-reimbursable Time & materials (T&M) Cost-plus-fixed-fee (CPFF) Cost-plus-incentive fee
Guaranteed Maximum Price (GMP)
Fixed Price
Cost Plus
Fixed price contracts
Pre-negotiated unit-price… Modified form of “fixed-price” contract. Based on “measurable” construction units. Unit prices for tasks are fixed. Contract scope is the total list of tasks. Specifications govern quality. Unspecified tasks must be negotiated. Used for pipelines, roadways, tunneling, etc. Quantities purchased may be not be limited. Called “Indefinite Quantity” or IDQ contracts Used when total scope is unknown.
How do you measure?
Porta-potty method…
3 ft
3 ft
10 ft
1 PP = 90 cu ft
May add incentives… Profit is based on performance Incentive formula must be clearly specified in
contract documents May have price ceiling Requires a performance “rating” Requires close supervision to ensure
contractor hits performance target
Cost-reimbursable contracts…
Time & materials contracts… Contractor is paid his actual costs for labor &
materials plus a 15% + mark-up for overhead Contract documents define eligible costs such
as labor categories, travel, rentals, permits, fees, other expenses…
Contractor must supply invoices for all expenses and certified time sheets for labor
Audit of costs & invoices is essential Profit is specified 10% + mark-up of costs
+
Time & materials contracts… Used when scope is completely unknown
and there is no time to design Owner assumes all of the risk Easy to write; difficult to administer End price is unknown Sometimes includes “upset” amount Contractor can make substantial profit
Example of T&M contract…
Materials cost $40,000 (invoices)Labor cost $60,000 (time
sheets)Sub-total $100,000Overhead 15% $15,000 (in contract)Sub-total $115,000
Profit/Fee 10% $11,500 (in contract)Grand total $126,500
Cost-plus-fixed-fee…
Actual costs paid for labor & materials Overhead rate generally fixed Fee is a “fixed” dollar amount that is
specified in contract documents Generally used when scope of work is
known but no time to design Contractor shares some risk Provides owner some control
Cost-plus-incentive-fee… Similar to cost-plus-fixed-fee Contractor is paid an additional fee or
bonus if certain specified conditions are met, such as time, cost or satisfaction of user
No bonus if conditions not met Incentive minimizes risk to owner Intent is to “motivate” the
contractor
Project controls…
Contracts are limited Increased supervision Increased accounting Decisions & finances will be audited
Contract inspection & supervision…
Verify quantity & time of operations Manpower & equipment use Material quality & quantity
Engineering sufficiency of work Quality of work Deviations from damage survey Negotiate claims for additional work Certification for occupancy
Roles for civil engineers…
Public works… public safety & critical facility operations Utilities operation & safety: water, elec, sewer, trash Public & critical infrastructure buildings Transportation: roads, hiways, bridges, rail Landfill & environmental operations Contract organization, operations & control Public liaison & information
Damage assessment – design firms Construction operations – construction firms
Estimators & schedulers Equipment & trades operation & direction Material & construction supplies
Records, documentation & funds control
Skills you will need…
Engineering analysis Construction take off & estimating Work scheduling Ordering & receiving Negotiating Common sense Supervision & leadership
See you Thursday…
