EPC Energy Conservation Program

Phase One: As-Built Survey

Scope and Purpose of As-Built Survey Program

EPC requires an as-built survey program which will support engineering assessments and design for its planned energy conservation project.  The targets of the conservation project are current high gas and electric bills.  As a non-profit organization, EPC wishes, by increasing energy efficiency in its Albuquerque facility's buildings, to redirect money presently spent on utilities to its stated mission.

The scope of the as-built interest is specifically limited to survey interests which are likely to be central to selection, design and sizing of various energy conservation equipment and modifications  as the project design is developed.  Interest areas will center on all parts of the existing natural gas and electrical systems.  The data collected during the as-built survey will be consolidated on drawings to be prepared as part of this proposed work.

Phase One Tasks

As-Built Survey

The EPC facility is currently two structures, a Residential Building and a Communal Building Group.  The Residential Building construction was complete in 2007.  The Communal Building **Group is a collection of buildings which have been joined through various construction regimes into a single large building.  The first of the Group's components was apparently constructed around 1977.

The as-built survey will require field surveyors to enter all areas of the two buildings, noting existing features within the structures which should be included on the resulting drawings.   Some limited physical (dimensional) measurement may be required, but almost all of the floor **plan lay out can be supplied by EPC on existing drawings.

The survey should include complete (observational) information on existing equipment, power supply, instrumentation, piping, vent structures and so on.

As-Built Drawings

The final product of Phase One work will be accurate, simplified drawings of EPC facilities which will present all measured and field corrected data necessary to support the energy conservation proposal design requirements.  Because the existing drawings are essentially architectural, they contain significant information which is outside the requirements of the energy conservation program.  For this reason, new drawings are proposed which contain only building information **which might be necessary for engineering and design tasks as the program advances (in its later development phases).**

The building floor plans and site lay out of the proposed new drawings can be traced directly from the existing drawings, omitting substantial information with is not relevant to the design process.  These tracings will become “master drawings” which can be reproduced as the basic format for electrical and mechanical drawings.  The form of the proposed drawings will be as simple as possible.  A scaled, one line drawing of the floor plans of the two buildings where, for example, wall structures, doorways and other features are all depicted as a single line, will allow the presentation of as-built information in an clear, uncomplicated graphic scheme.**

Both existing buildings have two floors.  The areas of the existing buildings will require two sheets  for the residential facility and four sheets for the communal facility  (one drawing for each of two stories).  Each drawing should be a standard sized sheet of 24” x 36” of a suitably durable, reproducible medium (drafting mylar).  These drawings can be produced manually or with a CAD system, but the informal nature of the final product should guide production.

Copies of the drawings are intended for use during the engineering and design phase, but also may be distributed to potential vendors during the RFP phase of the project.  No professional seal or implied accuracy liability is required for the information presented in the as-built.

Existing Inventory of Drawings

EPC currently has a complete construction set of the drawings for the Residential Building.  Although not CAD generated drawings, they are complete and well made.  The set is comprised of 25 sheets (counting the cover) and were produced about 2005 by the Residential Building's project (local) architect, Mr. Rick Bennett, appearing under his professional seal.  This set of **drawings will provide the lay out information (at a suitable scale) needed for the creation of the new drawing set for the Residential Building.

The Communal Building Group is another case.  EPC has four drawings which might partially support a similar process for the Communal Building Group.  Two of these sheets are floor plans for most of the current building (one – pencil on vellum, one – pencil on mylar) at 1/8” = 1'0” scale.  The other two are partial electrical drawings for part of the Communal Building Group.  The electrical drawings were made around 1977 and are under the professional seal of (local) architect Mr. Robert F. Armstrong.  The physical condition of these existing drawings is failing from age and improper storage, making the preparation of a replacement set very appealing.  Although current business activities of the previous architects are unknown, interested parties are free to contact them if desired.  No EPC contact has been initiated at this time.

Recap of All Proposed Drawings

Although the entire proposed set of new drawings may be as large as twenty individual sheets, it should be noted that the “master set” lay out sheets can be traced from existing drawings and the corresponding electrical and mechanical sheets can be prepared on reproducible copies of the “master set.”  The entire drafting scheme is minimalist.  The prevailing values will be clarity and accuracy rather than style or formal convention.

1, 2, 3 (first floor lay out) and 4, 5, 6 (second floor layout) “master set” of Residential and Communal Buildings

7, 8, 9, 10, 11, 12 duplicates of “master set” with electrical as-built information shown

13,14,15,16,17,18 duplicates of “master set” with mechanical, equipment and piping as-built information shown

19 a site lay out showing the buildings and the lot with electrical, water and natural gas supplies shown

20 (if required) a schematic diagram (P&ID style) showing the basic mechanical heat system

All the existing drawing sets in the inventory are available at the EPC facility.

Equipment Tagging

Equipment such as existing heaters, panel boxes, thermostats, etc. will be tagged during the as-built survey.  Numbers placed on such equipment will be noted on the appropriate lay out drawing.  This information will also be tabulated in a “data key” style spread sheet file where all known data concerning the numbered item can be consolidated.  EPC will provide the numbered tags, the resources and labor to create the computer file system from observational data provided by the field surveyors.  The final result will be reference numbers appearing on the proposed drawings and corresponding to items in the computerized file.  It is anticipated that this numbering process will be expanded to specifically identify rooms, doors, windows, receptacles, etc. but this work need not be included in the Phase One scope (it can be completed on an as required basis during the remainder of the project phases).

Access to the Site and Buildings

Mr. David Einerson of the EPC staff will serve as the Phase One contact.  Access will be provided to the facility, buildings and site by appointment through him.  Because EPC is the current residence of its active clients, access to some areas will require an EPC staff member to accompany field as-built surveyors, and will be best scheduled in advance (1 day).  Likewise, although existing drawing inventory is entirely available to surveyors, an advance schedule arrangement (1 day) will be required.
