Job Overview

This project qualifies you to evaluate a proposed residential building site and produce a documented readiness plan before any layout, clearing, excavation, or grading begins. The finished work product is a complete existing-conditions record — including photographs, a sketch, hazard and access notes, and drainage observations — plus a signed site-readiness checklist that ends in a written proceed, conditional-proceed, or stop-work decision.

You will confirm entry permission, walk the site perimeter, identify existing improvements and hazards, evaluate worker and vehicle access, observe drainage, record approximate existing grades, photograph and sketch the site from fixed reference points, and complete a written checklist that becomes the controlling document for Project 02.

This is the first project in this book. It does not disturb soil, drive stakes, or operate excavation equipment. Every later project in this book — staking, squaring, clearing, excavating, grading, and drainage work — depends on the existing-conditions record and readiness decision produced here.

Skills You Will Demonstrate

  • SP-001 — Conduct a documented site assessment of an assigned residential building site using a fixed sequence of observation, photography, and recordkeeping.
  • SP-002 — Identify and record site hazards, including unstable slopes, soft ground, standing water, overhead and underground utility indicators, contaminated material, and abandoned structures.
  • SP-003 — Verify and document access constraints for workers, delivery trucks, excavation equipment, concrete trucks, and emergency vehicles.
  • SP-004 — Identify and record existing site conditions, including structures, fences, retaining walls, driveways, wells, septic components, drainage features, overhead lines, vegetation, slopes, and neighboring improvements.
  • SP-005 — Locate and record visible property boundary markers without relocating or disturbing them.
  • SP-006 — Complete a written site-readiness checklist and issue a documented proceed, conditional-proceed, or stop-work decision.

Where This Skill Fits

This project opens the book. It has no prior site-preparation project to build on, so it establishes the reference points, documentation habits, and readiness decision that every later chapter relies on. The existing-conditions record you create here — property markers, hazards, access routes, drainage direction, and approximate grades — is the document Project 02 uses to establish the first building reference corner and baseline.

The stop-work discipline introduced here — recording an immediate stop-work condition and naming who must evaluate it — is the same discipline used throughout this book, including the pre-inspection review in Chapter 16 and the final site-readiness certification in Chapter 19.

Scope and Intended Use

This project covers:

  • obtaining and reviewing the available site plan, survey, property information, utility records, and permit conditions
  • confirming permission for non-destructive entry, inspection, marking, and photography
  • walking the site perimeter and identifying visible property markers without relocating or disturbing them
  • identifying existing structures, improvements, vegetation, slopes, and neighboring conditions
  • identifying access constraints and visible hazards
  • observing surface drainage and recording approximate existing grades
  • photographing and sketching existing conditions from fixed reference points
  • preparing a written site-readiness checklist and issuing a documented decision

This project does not authorize the learner to:

  • relocate, remove, or drive out any existing property marker, survey monument, or utility marking
  • drive stakes, disturb soil, clear vegetation, or operate excavation or grading equipment, which are outside this chapter's scope
  • enter a fenced, posted, unstable, flooded, or otherwise restricted area without separate written permission and, where required, a qualified escort
  • treat this assessment as a substitute for a licensed survey, geotechnical report, or utility-locate service; those remain separately required per Section 12 of this project
  • proceed to Chapter 2 staking work until this chapter's readiness checklist has been completed and a proceed or conditional-proceed decision has been issued

Any condition that meets the stop-work criteria in this chapter must be evaluated or corrected by the identified responsible party before site work continues.

Reference Conventions

Establish these references before the site walk begins, and use them consistently throughout the assessment.

TermDefinition
Property markerA visible survey monument, pin, or marker indicating a property corner or boundary line; located and recorded but never relocated or disturbed
Reference pointA fixed, named location — a property corner, existing structure corner, or flagged station — used consistently for photographs, sketch measurements, and elevation notes
Stop-work conditionA visible hazard or unresolved condition serious enough that site work may not proceed until a named responsible party evaluates or corrects it
Existing-conditions recordThe combined set of photographs, sketches, measurements, and written notes documenting the site as found, before any layout or ground disturbance
Site-readiness checklistThe document listing acceptable conditions, unresolved conditions, required professional reviews, permits, utility-locate requirements, and next actions, ending in a documented decision
Proceed / conditional-proceed / stop-work decisionThe three possible outcomes of this chapter: work may begin, work may begin only after named conditions are met, or work may not begin until a named condition is resolved

Site Identification and Assessment Record

Before beginning the walk, record the following directly on the site-readiness checklist:

Site address or parcel identifier: ______     Site plan / survey reference number: ______     Utility-locate reference number (if issued): ______

Date of assessment: ____________     Assessor name: ____________     Weather and ground conditions at time of assessment: ____________

Prerequisites

Common Field Fundamentals

Every site-preparation chapter in this book, from this chapter's existing-conditions record to the Chapter 20 capstone handoff, depends on an accurate, dated, reference-point-based record. Learning that discipline here, before any ground is disturbed, means every later chapter starts from a record you already trust.

BoundariesVisible property markers, located and recorded, never relocated
Existing conditionsStructures, fences, drainage, vegetation, slopes, neighboring improvements
AccessWorkers, delivery trucks, excavation equipment, concrete trucks, emergency vehicles
HazardsUnstable slopes, soft ground, standing water, overhead and buried utilities, contamination
DrainageObserved surface-flow direction during or after rainfall when practical
GradesApproximate existing elevation changes, approved site-measurement method
ZonesLikely footprint, material storage, topsoil stockpile, spoil stockpile, equipment movement, erosion controls
DecisionProceed, conditional-proceed, or stop-work, documented and signed

Property Markers and Non-Disturbance

Visible property markers establish the legal boundary of the site and control every layout measurement in Chapter 2. Locate and record each visible marker's approximate position relative to a fixed reference point. Do not pull, reset, tap in, or otherwise relocate a marker during this assessment, and do not assume a missing or ambiguous marker can be estimated; record it as unresolved instead.

C. Document and Permission Takeoff

  • Source documents: the available site plan, survey, property information, utility records, and permit conditions, obtained before the site visit.
  • Permissions: documented permission to enter, inspect, mark, and photograph the site, confirmed before entry.
  • Consumables: marking flags and flagging tape sufficient to temporarily flag identified hazards and reference points without relocating property markers.
  • Records retained: this chapter produces no fasteners, hardware, or physical components; its material takeoff is limited to documentation and temporary, non-destructive flagging materials.

D. Acceptance Standards

CheckStandard
Reference-point photographsEvery required photograph captioned with reference point, direction faced, and date; none missing without a documented reason
Site sketchIncludes north arrow, approximate scale note, and every reference point and improvement identified during the walk
Boundary marker logEvery visible marker located and logged; no marker relocated, reset, or disturbed
Hazard logEvery hazard identified in Step 6 logged with location, type, and stop-work determination
Access notesEvery access constraint identified in Step 5 logged with route, limitation, and affected vehicle types
Site-readiness checklistEvery section complete; decision is one of proceed, conditional-proceed, or stop-work; checklist signed and dated
ProcedurePermission confirmation, perimeter walk, hazard and access assessment, drainage observation, and checklist completion performed independently and in the required order

E. Preparation — Document Review and Entry Permission

  1. Obtain the available site plan, survey, property information, utility records, and permit conditions. Assemble every document before the site visit and note any document that is missing or unavailable.
  2. Confirm permission to enter, inspect, mark, and photograph the site. Obtain and record documented, non-destructive-only permission from the property owner or authorized representative before proceeding to Step 3.

F. Perimeter Walk and Existing-Conditions Identification

  1. Walk the site perimeter and identify visible property markers. Locate each marker relative to a named reference point without relocating or disturbing it, and log it in the boundary marker log.
  2. Identify existing structures, improvements, vegetation, slopes, and neighboring conditions. Record buildings, fences, retaining walls, driveways, wells, septic components, drainage features, overhead lines, vegetation, slopes, and neighboring improvements as they are encountered.
  3. Identify access constraints for workers, delivery trucks, excavation equipment, concrete trucks, and emergency vehicles. Log each route, width or clearance limitation, and the vehicle types affected.
  4. Identify visible hazards. Log unstable slopes, soft ground, standing water, overhead utilities, buried-utility indicators, contaminated material, abandoned structures, and restricted areas as they are encountered.
  5. Mark immediate stop-work conditions and record who must evaluate or correct each one. Flag the location from a safe distance without approaching or probing the hazard, and name the responsible party in the hazard log.

G. Drainage, Elevation, and Zone Planning

  1. Observe the direction of existing surface drainage during or after rainfall when practical. Record the observed or inferred flow direction, the date, and the weather condition at the time of observation.
  2. Identify likely locations for the building footprint, material storage, topsoil stockpile, spoil stockpile, equipment movement, temporary access, and erosion controls. Mark each likely zone on the site sketch.
  3. Record existing grades or approximate elevation changes using the approved site-measurement method. Note the method used and the reference point each elevation observation was taken from.
  4. Photograph and sketch existing conditions from fixed reference points. Complete the required photograph set and finish the site sketch with north arrow, scale note, and all identified reference points and improvements.

H. Site-Readiness Checklist and Decision

  1. Prepare a written site-readiness checklist. List acceptable conditions, unresolved conditions, required professional reviews, permits, utility-locate requirements, and next actions.
  2. Review the proposed work sequence against access, drainage, neighbor protection, and environmental constraints. Confirm the checklist reflects every constraint identified during the walk.
  3. Correct administrative and housekeeping deficiencies that can be resolved without disturbing soil. Document each correction made and each deficiency that remains open.
  4. Issue a documented proceed, conditional-proceed, or stop-work decision for Chapter 2. Select one decision, state the reasoning, and sign and date the checklist.

I. Recut and Closeout Procedure

  1. Resolve every open item before issuing a proceed decision. Classify each open item as documentation, permission, boundary, access, hazard, drainage, or professional-review before resolving it.
  2. Label and retain the completed record. Store the existing-conditions record and site-readiness checklist for use as the controlling reference in Project 02.

Skill Check

  1. Why must permission to enter, inspect, mark, and photograph the site be confirmed before Step 3 of the site walk?
  2. What is the difference between logging a hazard in general notes and logging it as a stop-work condition, and why does that distinction matter?
  3. Why must a visible property marker never be relocated, reset, or disturbed during this assessment, even if it appears to be in the wrong place?
  4. What information must accompany every fixed-reference-point photograph for it to satisfy the acceptance standard?
  5. What are three examples of visible hazards that meet the stop-work criteria in this chapter?
  6. Why is observing drainage during or after rainfall preferred over inferring it from ground contours alone, and what should the learner do when rainfall observation is not practical?
  7. What is the difference between a proceed decision, a conditional-proceed decision, and a stop-work decision?
  8. What must the learner do with administrative or housekeeping deficiencies that can be resolved without disturbing soil?
  9. Why must every access note identify the specific vehicle types affected by a route or clearance limitation?
  10. Why does Chapter 2 depend on the existing-conditions record and readiness decision produced in this chapter, rather than starting its own independent site review?

Issue the decision only after every section is complete. If any item is unresolved, name the required professional review, permit, or responsible party before issuing a conditional-proceed or stop-work decision.

Project Closeout

You have completed the first project in the site preparation sequence: evaluating and documenting a residential building site before any layout, clearing, excavation, or grading begins. This project required you to conduct a documented site assessment (SP-001), identify and record hazards (SP-002), verify and document access (SP-003), identify existing conditions (SP-004), locate property boundaries without disturbing them (SP-005), and complete a site-readiness checklist ending in a documented decision (SP-006).

You now have a complete existing-conditions record and a signed readiness decision that becomes the controlling reference for the next project: transferring the approved building dimensions to the site using control points, offset stakes, batter boards, and string lines.

File your existing-conditions record and signed site-readiness checklist with the project records. You will reference this exact record when establishing the first building reference corner in Project 02.
