Technical Memorandum Cost Criteria for 2010
System Capacity Plan
PREPARED BY: My Huynh

DATE: September 13, 2011

REVIEWED BY: Sonny Lunde

INTRODUCTION
This Technical Memorandum presents the methodology used to develop estimated costs for project shed areas
proposed in the Sacramento Area Sewer District System Capacity Plan 2010. The estimated costs may then be
incorporated into SASD’s rate and fee study.

1. DEVELOPMENT OF ESTIMATED COST
Estimates of the capital costs associated with the proposed project areas are order of magnitude estimates. An
order of magnitude estimate is one that is made without detailed engineering data, and uses techniques such as
cost curves and scaling factors from similar projects. The overall expected level of accuracy of the cost estimates
is approximately 30%. All costs presented in this memorandum have been adjusted to an Engineering News
Record construction cost index of 9527, which represents the average of the January 2011 ENR cost indexes for
the San Francisco area (10116) and the “20-Cities” ENR average (8938).
The estimated costs were developed using a baseline pipe construction cost with added cost and markups for
related items. An example cost estimate sheet for a hypothetical project is presented in Figure 1.

3. BASIS OF ESTIMATED COST

Technical Memorandum #7

Construction costs include costs for installation of gravity pipelines, force mains, and pump stations. The basis
for these costs is described below.

3.1 Baseline Pipeline Construction
Baseline pipeline construction costs were developed for open cut gravity sewer trunks, force mains, and
trenchless pipe construction. These costs are based on a combination of construction bids for projects in
Sacramento and other urban areas in California, catalog unit price costing, and adjustments to unit costs
identified in previous SASD Master Plans (2000 and 2006).
Both the baseline gravity pipe and force main construction costs include the following:
 Vertical trench walls to reduce utility conflicts
 Trench box or hydraulic shores
 Select, imported backfill in the pipe zone and native back fill above the pipe zone to the pavement
structural base. It is assumed that the spoil may be hauled to a local disposal site. Backfill would be
compacted to 90 percent to within 2 feet of the ground surface.
 Temporary pavement to be placed over excavated areas in traveled roads at the end of each day.
 Sump pump in the trench used for minor dewatering.
 Minor traffic control including two way flagging, construction area traffic signs, and channelizers.

3.1.1 Open Cut Gravity Sewers
Baseline unit pipe construction costs were developed for gravity collector and trunk sewers ranging from 8 to 42
inches in diameter for four depth-to-invert ranges: 8 to 16 feet, 16 to 20 feet, 20 to 24 feet, and 24 to 28 feet.
These unit costs are presented in Table 2. It was assumed that gravity trunk sewers installed by open-cut
construction would not be constructed deeper than 28 feet deep.
In addition to the baseline gravity pipe and force main cost assumptions, the baseline gravity vcp pipe
construction costs include the following assumptions:
 Pipe material: VCP for 8 to 36-inch sewers; and PVC-lined (or calcareous aggregate) RCP for 39-inch and
larger sewers.
 Manholes will be located every 400 feet in collector pipes (working pipe capacity of less than 1 mgd,
typically pipes 8-inch to 10-inch) and every 500 feet in trunk sewers (working pipe capacity of 1 mgd or
greater, typically pipes 10-inch or greater).
 Trench dams if needed to prevent migration of groundwater along the trench section and/or filter fabric
to prevent migration of soil or intermediate back fill into the pipe zone.
 Collector sewer not to exceed 19 feet in depth.

3.1.2 Open Cut Ductile Iron Force Main
Unit baseline pipe construction costs for force mains are presented in Table 3. In addition to the baseline gravity
pipe and force main cost assumptions, the baseline force main construction costs include the following
assumptions:
 A minimum of 4 feet of cover above the pipe.
 Pipe material: Ductile iron pipe.
 Air release valves, vacuum release valves, or combination valves located every 3,000 feet in 60-inch
diameter manholes.
 Trench dams installed at 100 feet spacing in areas with high groundwater along the trench section and
installation of filter fabric to prevent migration of soil or intermediate back fill in the pipe zone.
 Includes trust blocks.

3.1.3 Trenchless Pipe Construction
Trenchless pipe construction is an advantageous pipe method to install pipelines that minimizes impacts to the
public and the restoration. For this System Capacity Plan, baseline pipe construction costs were also developed
for microctunneling, bore and jack, and pipe ramming. Although pipe bursting is often a viable method for
installing and upsizing pipes, its dependency on local utility location information and pipe condition makes it
difficult to consider on a planning level document. The same goes for horizontal directional drilling, with its high
sensitivity to geological conditions. For this reason, SASD has chosen not to include pipe bursting and horizontal
directional drilling as one of its trenchless methods in the System Capacity Plan, but considerations for use can
be evaluated during the Project Development Phase. The following assumptions were made regarding
trenchless pipe construction:
 All highway and railroad crossing will require a casing.
 All major roads (4 lanes or more) will require a trenchless crossing.
 All creek crossing will be constructed using open cut methods (see creek restoration costs in later
section).
 Neither mircrotunneling nor bore and jack construction methods will be used in cobble areas (see
section on “cobble and hard rock construction” for definition of cobble area) Pipe ramming will be used
for required trenchless crossings in cobble areas. Pipe ramming requires a steel casing.
 Bore and jack equipment for 59-inch diameters and smaller is typically auger boring equipment. Auger
boring is not accurate enough for gravity sewer installation. Auger boring can be used to install casings
for force mains.
 Casing is determined by the outside diameter of the carrier pipe bell plus 24 inches with a minimum size
of 36-inches.
 Bore and jack equipment for 60-inch diameters and larger is typically open shield equipment (laser
target used to steer). Open shield equipment is accurate enough for gravity sewer installation.
 Except for microtunneling, unit pricing includes mobilization/demobilization, bore, casing (if specified),
and pipe. Microtunneling includes all of the previous items except for mobilization/demobilization. For

3.1.3.2 Jacking and Receiving Pits
The construction for microtunneling, boring and jacking, and pipe ramming pipeline installation also includes
costs associated with the jacking and receiving pits. If a long length of microtunneling is required, then a series
of drives with the associated pits will be used. The maximum drive lengths of the boring or tunneling machines
are shown in Table 5. These drive length are conservative and will work for most areas of Sacramento County.
The recommended costs for jacking and receiving pits are shown in Table 6.

3.2 Geotechnical Factors
Depending on location and site conditions, pipeline construction may require additional costs associated with
geotechnical factors. These additional costs include increased dewatering, additional sheeting and shoring, and
special equipment or methods associated with construction in difficult soil conditions such as cobbles or rock.
3.2.1 Additional Dewater
The baseline pipeline costs include the cost of sump pump in the trench for minor dewatering. Some areas of
Sacramento County require a more aggressive dewatering scheme. The cost of installation and maintenance of
each dewatering well could range from $1,000 to $5000. The range of costs depends on depth of wells, the need
for sand screens, and the proximity of electrical services for the pump motors. The cost of dewatering also
depends upon the spacing of the dewatering wells. To adequately dewater a trench with high groundwater,
dewatering wells are generally located at least 50 to 75 feet apart. If the soils have large amounts of clay or
other materials which decrease the capability to dewater the soils, wells are frequently spaced 50 feet apart. For
the purposes of this System Capacity Plan, it is assumed that the wells would be spaced 50 feet apart. Therefore,
the unit dewatering cost could range from $20 to $100 per foot.
Dewatering cost will be applied in areas of the County with known high groundwater as shown Figure 2.

3.2.2 Additional Sheeting and Shoring
Sheeting and shoring methods could range from hydraulic shores to interlocking full-sheets. The specific type of
shoring used will depend upon trench depths, soil conditions, and groundwater levels. For the purposes of
determining sheeting and shoring requirements for this System Capacity Plan, three different ground conditions
will be used: no groundwater, undeveloped areas with high groundwater, and developed areas with high

groundwater. For pipeline constructed in areas without high groundwater, it is assumed that hydraulic shores or
trench boxes will be used. This cost is included in the baseline pipe construction cost.
The recommended sheeting and shoring costs for the three conditions and various pipeline depths are
presented in Table 8. The cost of the solid shoring ranges from $1 to $3 per square foot. The cost of the sheet
piles ranges from $20 to $40 per square foot. These costs have been used to also assume that any excavation
deeper than 8 feet in areas of high groundwater area of the County, where the subsurface profile typically
consists of 10 feet of clay over clean sands. Therefore, additional dewatering costs will also be required for open
cut construction in areas of high groundwater (except where sheet piles are used), as indicated in Table 8.

3.2.3 Ground Condition
Large portions of Sacramento County have a significant amount of cobbles in the soil. These cobbles, which
originated from the Sierra Nevada Mountains and were carried and deposited in the Sacramento area by the
American River, are rounded and very hard. For this reason, the cobbles can be problematic when constructing a
pipeline. Therefore a cobble construction factor will be added to the portions of the projects in extra processing
of excavated material necessary to produce acceptable backfill, and shoring difficulties. For projects that will be
constructed before the road and utility improvement are built, the challenges are not as great as the projects
that are built after the road and utility improvements have been constructed. For this System Capacity Plan, the
cobble construction factor will be applied within the areas shown in Figure 3. Cobble issues reduce in magnitude
from the northeast to southwest in this area. For this reason, projects located on Gerber Road will have zero
cobble factor and projects located on Florin Road will have 50% cobble factor instead of the 100% cobble factor.
In the northeast corner of the SASD service area, there is hard rock located in the trench zone. This hard rock
significantly reduces construction productivity and adds considerable cost to pipeline projects. For this System
Capacity Plan, the hard rock construction factor will be applied to all projects located in the areas shown in
Figure 3.

3.3 Traffic Control

Technical Memorandum #7

Minor traffic control consisting of two-way flagging, construction area signs, traffic cones, and channelizers are
included in the pipe installation cost. For roads identified as having 4 or more lanes, additional traffic control will
be needed. Additional traffic control includes the cost of traffic design and use of flagging, construction area
traffic signs, temporary crash cushions, barricades, channelizes, flashing beacons, K-rails, and changeable
message boards. Traffic control on major roads could range $3000 to $6000 per day. If it is assumed that
construction will proceed at a rate of 100 feet/day, the equivalent cost would be $30 to $60 per foot. For this
System Capacity Plan, the following unit cost will be used:
 Increased Traffic Control: $45 per linear foot of alignment located in major roads (4 or more lanes).

3.4 Productivity Factors
3.4.1 Traffic/Utility Corridor Delay Factor
Constructing a pipeline in a busy road or a road with numerous utilities is slower (and therefore more costly)
than constructing a pipeline in a quiet residential or rural street. Often times, there are restricted work areas
and hours to maintain safe traffic flow, driveway access coordination, and utility conflicts. Therefore a congested
traffic/utility corridor delay factor reflecting the loss of productivity will be added to alignments on roads with 4
or more lanes.
 Congested Traffic/Utility Corridor Delay Factor: 15% of baseline pipe construction costs in major roads
(4 or more lanes).
3.4.2 Remove and Replace Delay Factor
Constructing a new pipeline in an alignment that requires the removal of the existing gravity sewer is more
costly than constructing a pipeline in a new alignment. The additional cost is caused by the necessary bypass
pumping and the extra processing of the excavated material to remove the broken pipe from the backfill
material. However, contractors are very creative and could typically avoid completely removing the pipe or
remove it at a lower cost than traditional means. For those reasons, the remove and replace delay factor will be
the following:
 Remove and Replace Delay Factor: 25% of baseline pipe construction costs.

DRAFT
3.5 Surface Restoration

Technical Memorandum #7

Surface restoration includes replacement of pavement for pipeline alignments in paved roadways and
replacement of landscaping or other vegetation for pipelines constructed in easements or across open land.
3.5.1 Pavement Restoration
To ensure that the pipe trench does not affect the integrity of the road, restoration will be made to the road
structural section above the pipe trench and overlayed. A tee trench will include a 6-inch thick asphalt concrete
pavement over 6-inches of 3/4 –inch aggregate base compacted to 95 percent. The asphalt concrete section will
extend beyond the trench walls by 12 inches. On both sides of the 6-inch thick pavement, a strip of 2-inch deep
grinding and new pavement overlay the road. The grinding and pavement will extend to lip of gutter, lane line,
or center of traffic lane.
To determine the cost of pavement restoration , two factors must be determined: width and unit cost, While the
width of pavement restoration does vary with pipe diameter, the width is more strongly influenced by factors
such as proximity to edge of pavement, raveling of trench wall, and strength of existing pavement. These factors
are hard to determine during the planning stage; therefore, for the System Capacity Plan, a pavement
restoration width of 15 feet (12 foot traffic lane with a 3 foot shoulder) and a pipe trench accommodating an 18inch pipe (42-inch wide trench), will be used.
For the purposes of this Master Plan, an average cost over the entire 15 foot width will be used, as follows:
 Pavement Restoration Cost (15 feet width): $100 per linear foot

3.5.2 Other Restoration
All trunk sewers and constructed outside of paved roadways and temporary lay down areas, if not constructed
by a developer as part of a subdivision, will require either revegetation or landscape restoration. Open cut creek
crossings will require creek restoration. Revegetation, also referred to hydroseeding, is used to restore pipeline
routes located in open fields. Landscape restoration is used when the alignment is located in the landscaped
medians or other landscaped areas. For new subdivisions, pipelines are usually constructed prior to constructing
the subdivision. For this reason revegetation and landscape restoration cost will be included as part of a new
subdivision cost and not part of the capital funding projection.
Where required, both landscape restoration and revegetation will be applied to the entire area disturbed by the
construction operation. Typically, the disturbed area is larger when the alignment goes through an open field
than when the alignment goes through a creek or an area with landscape improvements. For this reason, for this
System Capacity Plan, the revegetation width will be assume to be 80 feet, and the creek and landscape
restoration widths will be 40 feet. The following costs shall be used:
 Landscape Restoration (replanting in medians or landscaped areas, 40 feet wide): $4.00 per square
foot
 Revegetation (hydroseeding in open areas, 80 feet wide): $0.25 per square foot
 Creek Restorations (replanting, minor bank erosion control, 40 feet wide): $12.00 per square foot

3.6 Sewer Structures

3.6.1 Junction Structures
Junction structures are use to combine flows coming from different pipes into one out flowing pipe. They are
required at the connection points of trunk sewers to interceptors. If the trunk sewer is being connected to an
existing or previously constructed interceptor, then the cost for this junction structure will be included in the
trunk sewer cost estimate. If the junction structure is constructed at the time of the interceptor construction,
then it will be assumed to be included in the interceptor cost estimate and not included in the SASD trunk sewer
construction cost.
Transition structures and turning structures are similar to junction structures in construction methods and cost
but differ in not combining flows. For this System Capacity Plan, transition and turning structures will be costed
like junction structures using Table 9.

3.6.2 Pump Stations
Pump stations are used to convey wastewater using pressurized pipelines. Costs can vary greatly depending on
how much wastewater is being conveyed an on how far the wastewater will be pumped. Typically pump stations
of the same firm capacity used to raise the hydraulic grade line (lift stations) require smaller pumps and
appurtenances than pump stations used to convey wastewater from one location to another and are therefore
less costly. The total dynamic head of pump station is a factor for determining the pump size, motor control
center size, switch board size, wet well size, as well as other appurtenances. For those reasons, the pump
stations cost shown in Table 10 are base on three different scenarios representing low, medium, and high head
pump stations.

Often times, pump stations are upgraded to increase the pumping and storing capacity. For increasing the
capacity of an existing station, use the following cost factors:

3.7 Mobilization and Demobilization
These costs usually generally cover contractor activities when the contractor initially moves construction
facilities and equipment to the project site and at the end of the project when removing facilities and equipment
from the site. These costs also include temporary construction needed to begin the project (access roads,
power, internet, etc.). Typically language in SASD construction contracts limit mobilization and demobilization
bid cost to approximately 5 percent to prevent spending an unreasonably large portion of the construction cost
prior to construction.

 Mobilization/Demobilization: 5% of the Construction Cost Subtotal

3.8 Contingencies
This contingency is used to adjust the Estimated Construction Cost Subtotal such that the total cost will account
for unforeseen economic variables that are difficult to quantify or cover portions of work that were not
estimated. The percentage used for an overall project will vary depending upon level of effort at various stages
of the project. The percentage used is adjusted based upon detailed or lack of detailed geotechnical, utility, and
other project details and information. Due to a lack of detailed information during the planning phase, a
contingency factor of 30 percent is considered appropriate for planning level costs.
 Contingencies for Unknown Conditions: 30% of the Estimated Construction Cost Subtotal.

3.9 Easement Acquisition
The acquisition of easements can vary in cost depending on the incidentals (title reports, appraisals, etc.) and
cooperation of the property owners. On average, the cost of acquiring an easement is $7000 per parcel and do
not include the price of the easement. Because higher cost construction projects do not necessarily yield
proportionally higher costs easements and real estate acquisitions, these costs are separately calculated and
excluded from the typical 25% markup for engineering, administration, and legal costs.
Land acquisition is required for any construction area or pipeline located outside of the public right-of-way.
However, if the alignment of the trunk sewer is within a new development being constructed, it is assumed that
the easement will be granted to SASD as a condition of the development. Therefore no easement acquisition
costs will be incurred by SASD.
Easements can vary in cost. SASD usually acquires permanent easements at 50 percent of the land’s fee value as
determined by an independent appraiser. Temporary easements are acquired at 10 percent of the appraised fee
value for a 12-month usage period. Because of unexpected delays to project schedules, temporary easements
are typically obtained six months beyond the need of the easement or a minimum of two years, whichever is
greater. To ensure that property owners work with SASD, the minimum price for a temporary construction
easement and a permanent easement is $500 and $1,000, respectively. Based on Sacramento County Assessor’s
data for 2010, undeveloped land values can greatly depending on the location of property but, averages around
$8 per square foot. Being a planning level document and real estate typically representing a small percentage of
the project cost, it is appropriate at this level to not distinguish between uses of land and to apply the following
costs:





SASD Acquisition Cost : $7,000 per parcel
Easements in a Newly Constructed Development: No cost to SASD
Temporary Construction Easement (80 feet width) : $0.80 per square foot per year
Permanent Easement (20 feet wide for pipelines, 120 x 120 feet for pump station): $4.00 per square
foot

3.10 Engineering, Administration, and Legal Costs

Technical Memorandum #7

Typically, a markup is applied to the Estimated Construction Cost to account for the various costs in bringing a
planning level concept through design, construction, and closeout. The engineering, administration, and legal
cost item will account for all reasonably anticipated cost items for both the design and a construction phase,
assumed:
 Engineering, Administration, and Legal Costs: 25% of the Total Estimated Construction Cost

PIPE RAMMING COST
Assumptions:
‐ Pipe ramming is most useful in short drives and shallow applications.
‐ Mobilization and demobilization cost will be included in the unit price of pipe ramming.
‐ Pipe installation cost will also be include in the price of pipe ramming.
‐ Due to the lack of available cost information on pipe ramming, unit price cost for pipe ramming will be 
obtained from ENR CCI adjustments from Master Plan 2000.
‐ Casing to accommodate carrier pipe bell plus 12 inches.
‐ Smaller pipelines (15‐inch diameter or smaller) will be using pipe ramming for force mains, pipe material will 
be ductile iron.
‐ Larger pipelines (18‐inch diameter or greater) will be using pipe ramming for trunk sewers, pipe material 
will be reinforced concrete.
‐ Jacking and receiving pits will be separate items and are not included in the unit cost for pipe ramming

ADDITIONAL SHEETING AND SHORING COST
Assumption:
‐ There is limited information on project cost for sheeting and shoring. Projects are typically bid on a lump sum basis and therefore making it 
difficult to determine actual sheeting and shoring cost.
‐ Adjust unit pricing from SASD Master Plan 2000 based on ENR CCI.

ADDITIONAL TRAFFIC CONTROL COST
Assumptions:
‐ Minor traffic control consisting of two‐way flagging, construction area signs, traffic cones, and 
channelizers are included in the pipe installation cost.
‐ Additional traffic control to be used on major roads. Major roads have 4 or more lanes.
‐ Because traffic control is usually bid as a lump sum item, it is difficult to determine traffic control 
costs from previous project bids. Therefore traffic control cost are obtained from catalogued unit 
items.
