11.1 Field Observations, Site Reports & Non-Conforming Work

Core Focus: Field observation represents the landscape architect's primary mechanism for safeguarding design intent and protecting the owner's interests during construction. Candidates must understand the critical legal boundaries separating periodic observation from continuous inspection, the landscape architect's authority to reject non-conforming work versus the owner's exclusive power to stop work, the standard components of AIA Document G711 site reports, and the rigorous protocols for documenting and correcting defective work.

---

1. Scope and Legal Purpose of Field Observations

During the Construction Administration (CA) phase of a landscape architectural project, the landscape architect transitions from design author to contract administrator. Standard industry agreements—including the AIA Document A201 (General Conditions of the Contract for Construction) and ASLA Standard Professional Services Agreements—define the precise scope and limitations of the design professional's site presence.

Core Purpose of Site Visits

Under AIA A201 Section 4.2.2, the landscape architect visits the site at intervals appropriate to the stage of construction, or as otherwise agreed in writing, to accomplish three specific objectives:

1. Evaluate Progress and Quality: Become generally familiar with the progress and quality of the portion of the work completed.
2. Verify Contractual Conformance: Determine in general if the work observed is being performed in a manner indicating that, when fully completed, it will be in accordance with the Contract Documents.
3. Report to Owner: Keep the owner reasonably informed about the progress and quality of the work, reporting observed defects, deficiencies, and deviations from the drawings and specifications.

| - Not an insurer or guarantor    - Does NOT supervise means/methods     |
+-------------------------------------------------------------------------+

Periodic Observation vs. Continuous Inspection

A vital distinction on the LARE is the contractual difference between "observation" and "inspection":

• Periodic Observation: The standard level of basic CA services. The landscape architect is not required to make exhaustive, continuous, or full-time on-site inspections to check the quality or quantity of the work. The landscape architect does not guarantee that the contractor will fulfill contract obligations, nor does the landscape architect assume responsibility for contractor errors, omissions, or failure to carry out the work in accordance with the Contract Documents.
• Continuous Inspection / Resident Project Representative (RPR): When an owner requires full-time, daily oversight, the agreement must be augmented to include an RPR or a "Clerk of the Works." Even under continuous observation, the RPR does not direct the contractor's labor force or supervise safety procedures; their function is continuous documentation and quality verification.
• Exhaustive Formal Inspection: Contractually reserved for two distinct milestone events: the inspection to determine Substantial Completion and the inspection to determine Final Completion.

2. Division of Authority & Liability Boundaries

Construction contracts establish a strict tripartite relationship between the Owner, the Contractor, and the Landscape Architect. Understanding who has legal authority to act—and who bears liability for errors—is one of the most heavily tested areas on the LARE.

+-------------------------------------------------------------------------+

Authority to Reject Work vs. Authority to Stop Work

• Landscape Architect's Authority to Reject Work (AIA A201 Section 4.2.6): The landscape architect has the affirmative authority to reject work that does not conform to the Contract Documents. Whenever the landscape architect considers it necessary or advisable, they also have the authority to require special inspection or testing of the work, whether or not such work is fabricated, installed, or completed. Rejection must be communicated promptly in writing.
• Owner's Exclusive Right to Stop the Work (AIA A201 Section 2.4): If the contractor fails to correct work that is not in accordance with the requirements of the Contract Documents, or repeatedly fails to carry out work in accordance with the contract, the Owner may issue a written order to the contractor to stop the work, or any portion thereof, until the cause for such order has been eliminated.
• The Golden Rule of CA Liability: The landscape architect must NEVER issue an order to stop work. Ordering a shutdown of the job site breaches the contract, usurps the owner's legal prerogative, and exposes the landscape architect to massive contractor claims for project delay damages, idle equipment costs, and lost labor productivity.

Construction Means, Methods, and Site Safety

Under AIA A201 Section 3.3.1, the contractor has sole, exclusive control over, and responsibility for:

• Construction means, methods, techniques, sequences, and operational procedures
• Coordination of all portions of the work under the contract
• Safety precautions, OSHA compliance, trench shoring, scaffolding, and job site security

If a landscape architect volunteers advice, dictates equipment types, directs an excavator operator, or instructs workers on how to brace an unstable excavation, the landscape architect strips the contractor of legal responsibility and assumes primary tort liability for any resulting structural failure, worker injury, or fatal collapse.

Protocol for Immediate Safety Hazards

What should the landscape architect do if they observe an imminent life-safety hazard on site (e.g., an un-shored 8-foot-deep trench adjacent to an active sidewalk, or a crane operating dangerously close to overhead high-voltage power lines)?

1. Do NOT direct the contractor's workers to alter their work or exit the trench. (Directing workers assumes control over site safety means and methods).
2. Immediately notify the Contractor's designated Job Site Superintendent of the observed hazardous condition in person and follow up immediately in writing.
3. Notify the Owner and the Owner's representative immediately.
4. If the hazard poses an immediate, catastrophic threat to human life and the superintendent refuses or fails to act, contact local municipal emergency authorities (e.g., local building official, fire marshal, or police) to protect public safety.

3. Field Observation Reports: Structure & Best Practices

Every site visit must result in a written, contemporaneous legal document known as a Field Observation Report (standardized in AIA Document G711). Contemporaneous records created on the day of observation carry immense legal weight in arbitration, mediation, and litigation.

Essential Components of a Professional Field Report

1. Weather and Environmental Conditions: Recording ambient air temperature, recent precipitation, wind, and soil moisture conditions is essential. Many site construction activities are weather-dependent: asphalt placement requires ambient temperatures >= 50°F; concrete placement requires protection below 40°F or above 90°F; planting backfill must not occur in frozen or saturated soils; retaining wall backfill compaction fails in waterlogged conditions.
2. Personnel on Site: Documenting which subcontractors (e.g., hardscape, irrigation, earthwork, electrical) are active and approximate labor counts. This data becomes vital if the contractor later files delay claims or requests weather-related time extensions.
3. Work Observed in Progress: Factual, objective narrative describing active operations (e.g., "Earthwork subcontractor placing 6-inch lift of crushed aggregate base along north pedestrian promenade").
4. Deviations and Deficiencies Noted: Precise documentation of work failing to conform to plans and specifications, referencing drawing sheet numbers and specification section numbers.
5. Photographic Log: Photographs must include a timestamp, direction of view (e.g., "Looking northeast toward Station 4+50"), a physical scale reference where appropriate, and an objective caption. Avoid subjective language (write "Paving joint width measures 0.75 in; Section 32 14 00 specifies 0.1875 in," rather than "Sloppy contractor workmanship on paver joints").
6. Prompt Distribution: Issue the report within 24 to 48 hours to the owner, general contractor, and consulting team members.

4. Non-Conforming Work Protocols: Notices & Corrective Actions

When work is observed that fails to satisfy the Contract Documents, the landscape architect must follow a legally rigorous protocol to protect the owner without overstepping administrative authority.

| 5. RE-INSPECTION: Field verification and formal closure of NCN          |
+-------------------------------------------------------------------------+

Non-Conformance Notice (NCN) / Notice of Non-Compliance

A formal written notice issued by the landscape architect to the general contractor that details:

• The exact physical location of the defective work
• The specific contract requirement violated (citing sheet number, detail title, and specification section/paragraph)
• The precise nature of the deficiency
• A directive to stop further work that covers, embeds, or compounds the defective assembly until resolved
• A deadline for the contractor to submit a written Corrective Action Plan (CAP)

Corrective Action Plans (CAP)

The contractor must submit a formal CAP detailing the proposed methodology, equipment, and timeline to remedy the non-conformance. The landscape architect reviews the CAP for conformance with design intent. Remedial work, including demolition of non-compliant materials, re-testing, and re-inspection, must be executed at the contractor's sole expense with no extension of contract time.

Owner Acceptance of Non-Conforming Work

Under AIA A201 Section 12.3, if the Owner prefers to accept work that is not in accordance with the requirements of the Contract Documents, the Owner may do so instead of requiring its removal and reconstruction, in which case the Contract Sum will be reduced by an equitable amount through a formal Change Order.

• Landscape Architect's Role: The landscape architect evaluates whether accepting the non-conforming work impairs structural integrity, public safety, accessibility codes, or overall utility, and advises the owner on an appropriate monetary credit value. The landscape architect cannot unilaterally accept non-conforming work on the owner's behalf.

6. Real-World Case Scenario: The Saturated Planting Soil Crisis

The Situation: On a large municipal park project, the landscape architect arrives for a scheduled bi-weekly site observation following 36 hours of continuous, heavy autumn rainfall. Section 32 91 13 (Planting Soil Preparation) explicitly states: "Do not handle, spread, rototill, or place planting soil when moisture content exceeds 20% or when soil is in a plastic, muddy, or saturated state." Despite standing water across the site, the landscape contractor's crew is using heavy tracked skid-steers to spread and grade imported bioretention soil mixes across the sunken rain garden beds. The heavy machinery is visibly churning the soil into an impervious, smearing slurry, destroying soil macropores and subgrade infiltration capacity.

The Landscape Architect's Actions:

1. The landscape architect approaches the General Contractor's on-site project superintendent (avoiding direct instructions to the equipment operators).
2. The landscape architect points out the saturated conditions and the explicit prohibition in Section 32 91 13.
3. The superintendent argues that halting work will delay the project schedule and refuses to stop grading.
4. The landscape architect does NOT yell at the machine operators to stop or order the site shut down. Instead, the landscape architect:
   • Takes immediate, timestamped digital photographs of the standing water, the soil slurry, and the machine track ruts.
   • Issues a written Non-Conformance Notice (NCN) to the General Contractor within 3 hours, citing Section 32 91 13, rejecting the placed bioretention soil, and requiring in-situ infiltration testing per ASTM D3385.
   • Sends an immediate email notification to the municipal project manager (the Owner) summarizing the situation and attaching the NCN.
   • Documents the entire event objectively in AIA Document G711 Field Observation Report #14.

Resolution: Subsequent double-ring infiltrometer testing reveals the compacted bioretention bed achieves an infiltration rate of only 0.1 inches/hour versus the specified 5.0 inches/hour. The General Contractor is required to excavate, remove, and replace the ruined 18-inch profile of bioretention soil and decompact the subgrade at the contractor's sole expense, without any time extension.
