Project Management

Program

(PMPro)

• Planning officially begins when a project is funded

• Notable quotes after project funding:o “How did this get funded!”o “What can we do with this funding?”o “How many homes do we have out there anyway?”o “We’re going to need more funding to build that”o “That’s not federal trust property.”o “Who developed this cost estimate?”

Business as Usual

• O&M considerations addressed at completion of construction

• Notable quotes after construction completion:o “Might as well weld the door shut. Might last longer that way.”o “No one at Tribe capable of operating this.”o “Not sure how Tribe is going to afford operation when things start to break.”o “Why did we build such a complicated system?”o “Wish we had time to provide as-builts.”o “I guess this binder of manufacturers’ submittals is the O&M manual.”o “What type of training is the contractor going to provide?”o “How is the tribe going to fund operator training?”o “SDS is O&M by replacement. We’ll be back in 10 years.”

Business as Usual

• Planning begins prior to project listing• Data & system/utility knowledge through sanitary

surveys

IHS Survey Definition

Sanitation Facilities include water, sewer, and solid waste

Onsite in-depth assessment of facilities, equipment, operation and maintenance (O&M) of the system

Goals of the IHS Survey Identify system deficiencies and plan for

improvement (SDS) Identify problems affecting quality of water

or environment Gather data for designs, preliminary

engineering reports/master plans Identify tribes technical, financial,

managerial capacity and training needs Facilities inventory (IHS data systems) IHS staff training

Goals of EPA Sanitary Survey Evaluate 8 elements of water systems

Hypothetical Project Existing 100,000 gallon storage tank

serving public water system (PWS) is deteriorated and in need of replacement. What data must be collected in order to design new storage tank

Data for Storage Tank Design Number of service connections (i.e.

demand) Existing storage capacity Existing source water capacity/production Fire flow requirement Existing distribution system capacity for

fire flow delivery (requires hydraulic model which requires composite dwg)

Existing distribution system pressures Communities long term development plan Tribes capacity to operate

OMDS & GIS Development• Visual representation of asset inventory

w/links and attribute tables• Hydraulic modeling platform• Sanitary survey/EPR design info.• As-built scans, well logs• SDS O&M score• Utility rate studies/evaluations• O&M manuals

Improved IHS STARS Data System

Using ESRI ArcView/ArcReader on the

NavajoDSFC DE-OM Meeting

April 2012

Where in the world is that waterline, anyway?

The NTUA contracted the GIS mapping of all of the water utilities on the Navajo Reservation, including waterline, tanks, wells, valves, etc. The IHS has been using that valuable data for hydraulic modeling and other important project-related tasks.

ArcView as a Planning and Design Tool

• Locating nearest existing or planned waterline• Identifying nearby homes• Avoiding right-of-way obstacles• Locating other existing utilities• Storing data on existing surveying control

points• ArcPad on a mobile device allows all this to be

done in the field

Homeowner submits application - site visit completed and GPS reading entered into ArcView

Topo Map from ESRI online support superimposed with aerial image to view home and section lines

Land Status layer helps determine that home is in Allotment # 1880

Zoomed out view shows home in relation to the existing (green) waterline and close to SDS waterline SDS-NM17448-0104

Home added to SDS Project in Attribute Table

Maps and namelists can be easily be printed to submit for SDS

ArcView as an Operation and Maintenance Tool

• One centralized source for all as-built data that can be easily transmitted and shared

• Hyperlinks allow storage of project as-builts with pertinent design data

• Changes in project status automatically displayed based on changes to attribute values

• ArcPad on a mobile device allows operators/engineers/technicians to access data on any facility while at the site

View Home Details using Hyperlink

View Waterline Profiles using Hyperlink

View Well Details using Hyperlink

ArcView provides:

• An electronic, georeferenced “base map” alternative to cumbersome mylar and paper copies of as-builts

• A forum to integrate the Tribe’s GIS data with our hydraulic models and survey data

• A tool to determine the easiest way to extend services to a home by identifying the nearest existing, funded (PDS) or proposed (SDS) waterline

• Coordinate information, based on any system, for waterline tapping or other permits

• A way to store and geographically organize project as-builts

If the sanitation facilities we construct do not meet their design life how does that affect our ability to provide sanitation facility access to all homes.

Proposed additional OMDS information

Seemless conversion of dwg. files to shape files GPS surveying more prevalent User friendly data (ex. STARS) systems Ensuring knowledge remains as people move on Increased reliance on data systems by multiple

agencies Decreasing construction funding resulting in focus on

sustainability
