Appendix - GSA

Narrative.
1. Description of at least two potential electrical
systems and a baseline system.
– General characteristics of a baseline system are
described in Chapter 1, General Requirements of
this document.
2. Proposed special features of electrical system.
3. Code compliance statement.
Certification Requirements
1. The architect/engineer (lead designer) must certify
that the project has been conceptualized to comply
with ASHRAE 90.1 and will meet GSA’s energy goal
requirement.
2. Green building (sustainable) design concepts—
LEED strategy.
3. Life cycle cost analysis.
– VE decisions and commitments that were made
during this phase by the Project Team.
4. In bullet form, identify how proposed design features
will support performance expectations of the project.
Expectations are identified in the project’s design
program and within the Functional Objectives
Matrix in Appendix A.2.
Final Concept Cost Estimate
A cost estimate must be provided. It should comply
with the requirements for concept stage estimate stated in
the Cost Estimating Requirements of the Appendix’s
Section A.1 of this Facilities Standard.
Cost estimates must separate costs for interior tenant
buildout from core/shell cost items as described in the
GSA New Pricing Guide. The interior buildout cost must
be divided by each building tenant.
Design Development
Site Planning and Landscape Design
Calculations.
1. Site storm drainage combined with building storm
drainage, and sanitary sewer calculations.
2. Storm water detention calculations, if applicable.
3. Parking calculations, if applicable.
4. Dewatering calculations
– Calculations modeling dewatering rates during
dry and wet season excavation. Calculations must
take into account effect of dewatering on adjacent
structures and improvements.
– Calculations must assume a specific shoring
system as part of a comprehensive excavation
system.
Narrative.
1. Site circulation concept, explaining:
– Reasons for site circulation design and number of
site entrances.
– Reasons and/or calculations for number of
parking spaces provided.
– Reasoning for design of service area(s), including
description of number and sizes of trucks that can
be accommodated.
– Proposed scheme for waste removal.
– Proposed scheme for fire apparatus access and
fire lanes.
2. Site utilities distribution concept.
– Brief description of fire protection water supplies.
– Brief description of fire hydrant locations.
3. Drainage design concept.
4. Landscape design concept, explaining:
– Reasoning for landscape design, paving, site
furnishings, and any water features.
