Construction Cost Trends
Construction Costs have risen approximately 38.7% since
?
2004. Material price increases affect both City Capital
Projects and routine maintenance.
Increases have occurred for some of the most common materials used
?
in Roadway and Building Construction.
Concrete–Since 2004; up 27.8%
?
Asphalt –Since 2004; up 113.5%
?
Steel–Since 2004; up 68.5%
?
Other Materials that have seen large increases in costs since 2004.
?
•
Aggregate (Gravel), Copper, Gypsum, and Lumber (Although
Lumber Prices have seen a slight decline in recent months).
Some Industry experts expect a moderation in construction cost
?
increases.

Additional Factors Which Influence Construction
?
Costs:
Increases in Labor Costs
?
•
Increases in Salaries and Overtime.
•
Increases in Health Care Costs.
•
Construction volume is increasing at a rate faster than the
workforce.

Global Influences (Competition for Resources)
?
•
Over the last 20 years, China has been evolving into a more
industrialized nation. To construct the infrastructure needed
to support their new economy, China has consumed over
half of the available concrete and over 36% of the available
steel.
National and Regional Influences
?
•
Catastrophic events, such as Hurricane Katrina, impact
material availability and draw on labor resources as they are
shifted to the impacted region.
Construction Cost Trends
(Continued)
Fuel
?
•
Long term cost trend is up.
•
Although fuel costs have recently gone down, diesel fuel
has seen a 26.6% increase over the last 12 months.
•
Higher prices impact equipment and transportation
costs.
Higher Construction costs affect both Capital project
?
construction and many Maintenance activities.
Additional Project Cost Drivers
For many Capital Projects, Construction costs often are only
40% -60% of a project’s Total Project Cost.
Property Acquisition, i.e. Right-of-Ways and
?
Easements
•
City Real Estate values have increased 57.45% since 2003.
•
Purchase of Right-of-Way and easements from numerous
properties for City building and roadway projects.
•
Buildings: Need for optimal location or need for parking.
•
Roadways: Acquisition ranges from total takes to temporary
easements. Dependent on length of roadway, can exceed 100
property acquisitions per project.
Additional Project Cost Drivers
(Continued)
Private Utility Relocations
?
•
City must purchase Utility Easements/Rights-of-
Way if utility is currently located in a valid
easement. This is in addition to right-of-way and
easements needed for the construction of the
roadway.
•
.
Undergrounding vs. Overhead relocations
Undergrounding of Private utilities can cost 2-3
times more than overhead relocations. Utility
relocation costs continue to escalate based on
labor, equipment, and material cost impacts.
Additional Project Cost Drivers

Project Enhancements
?
Public Works is committed to providing projects
?
consistent with a Quality Physical Environment. This
includes:
Pedestrian, Bicycle Safety, and Trails
?
Landscaping
?
Streetscaping
?
Essential Facilities Designed for Category II
?
Hurricane
Construction Impact Limitations
?
Additional Project Cost Drivers
(Continued)
Federal Transportation Funding requires the
?
study, design, and potential construction of
Soundwalls. This impacts design, right-of-
way, and construction costs.
Environmental Impact Reductioncan add to
?
construction costs and often requires
additional acquisition and design for
mitigation areas.
Project Estimates
What should be recognized about Project
?
Estimates?
•
Initial project budgets and schedules are updated
throughout.
•
The Project Development Process can take from 4 to 12
years to complete for major projects. Urban reconstruction
projects may take even longer to complete.
•
Even with modest inflationary rates, total project costs will
escalate over the life of a project.
Project Estimates (Continued)
To illustrate these considerations, let us briefly
?
review the Princess Anne Road/Kempsville Road
Intersection Project Development Process to date:
In FY1999-2000 (Project was re-introduced in CIP)
?
•
Study Only, No Design
•
Total Project Cost (TPC) $15.1M (S.A. -$2.5M, Const. $10M)
In FY 2001-2002
?
•
Design Complete to 35% Stage
•
TPC $27.7M (S.A. -$6.8M, Const. $17.0M)
In FY 2006-2007
?
•
Design Complete to 90% Stage
•
TPC $55.8M (S.A. -$23.5M, Const. $21.3M)
Getting the Best Construction
Price
The goal is to make sure the City gets the best
?
construction price for its projects, in any market
conditions. What are we doing to get the Best
Construction Price?
•
Focusing on initial Project Planning to better identify initial
project requirements and set initial scope, schedule, and
budget. Developing a cost database for tracking cost trends
for project cost estimating purposes.
Getting the Best Construction
Price (Continued)
•
Surveyed local contractors and
Architectural/Engineering firms for input.
•
Materials, labor, and fuel are fixed costs and subject to
market conditions.
•
Insure that construction documents are clear and
unambiguous.
•
Assignment of risk for unforeseen conditions.
Getting the Best Construction
Price (Continued)
Focusing on Quality of Construction
?
Documents
•
Project team constructability reviews at major
milestones
•
Review of construction contract documents for
coordination/correlation of plans and
specifications.
•
Reduce certain project risks prior to construction
.
•
Identify and pre-coordinate utility conflict resolutions.
•
Provide clear and workable maintenance of access and
maintenance of traffic plans.
Getting the Best Construction
Price (Continued)
Use most suitable contract method for
?
project delivery
.
•
Design-Bid-Build
•
Prequalification of Bidders for specialty
construction
•
Design/Build
•
PPEA and PPTA –Funding mechanism for
Design/Build, not project delivery.
•
Construction Manager at Risk
Summary
Construction labor, material, and fuel costs have
?
increased substantially over the last several years.
Since 2004, Construction costs have risen
approximately 38.7%.
Other factors besides construction drive total project
?
cost. One of which is Site Acquisition, which has
risen 57.45% since 2003.
In any market, the focus is on Getting the Best
?
Construction Price.
