Block Retaining Wall

This proposal covers a segmental retaining wall install at {{client_address}} — {{wall_length}} linear feet with maximum height of {{wall_height}}.

Excavation

• Layout wall per design

• Excavate behind wall face to allow for base course and geogrid

• Excavate for leveling pad (4"–6" below finished grade)

• Remove any organic material or unsuitable soil

Leveling pad

• Install 6"–8" of compacted 3/4-minus crushed aggregate

• Level and compact with plate compactor

• Use builder's string and level to verify

First course (base)

• Set first course of {{block_type}} on leveling pad

• Check level, both front-to-back (with 1% back-batter) and side-to-side

• Small adjustments with rubber mallet

Stacking

• Stack block in running bond pattern per manufacturer specs

• Backfill with 3/4-minus drainage stone as each course rises

• Install geogrid per manufacturer requirements (typically every 2–4 courses for walls over 36")

• Compact drainage stone behind wall in lifts

Drainage

• Install 4" perforated drain pipe at base (wrapped in filter fabric) for walls over 36"

• Drain pipe outlets to daylight or storm system

• Drainage stone extends at least 12" behind the block face

Cap

• Install cap stones on top course with construction adhesive

• Miter or blend inside and outside corners

Backfill & finish

• Backfill behind wall with approved soil

• Restore grade to original elevation (or per design for raised bed)

• Clean up debris; haul-off excess soil

Estimated duration: 3–5 working days for typical walls; longer for walls with complex corners or step-downs.

Start date: {{start_date}}.

Total contract price: {{total}}

• **Deposit: {{deposit}}** — signing

• **Balance: remainder** — at completion and walkthrough

Balance due at completion.

Invoices are due upon receipt. Payments more than ten (10) calendar days past due accrue a service charge of one and one-half percent (1.5%) per month on the unpaid balance, or the maximum rate permitted by law, whichever is less. {{contractor_name}} reserves the right to stop work and preserve lien rights if any progress payment is not received within five (5) business days of the due date. All retained mechanic's lien, stop notice, and bond rights under applicable state law are preserved.

The following items are specifically NOT included in the contract price and are the responsibility of {{client_name}} unless added by written Change Order:

• Permits, plan-review fees, and jurisdictional inspection fees unless explicitly itemized above

• Repair or remediation of pre-existing code violations discovered during the work

• Asbestos, lead paint, mold, or other hazardous material abatement

• Structural engineering, architectural drawings, or third-party design services

• Finish selections, fixtures, or appliances not listed in the itemized scope

• Work on concealed systems (electrical, plumbing, HVAC, framing) beyond the points of connection identified

• Landscaping restoration beyond returning disturbed areas to rough grade

• Post-completion cleaning beyond construction broom-clean

• Engineering stamp (required in many jurisdictions for walls over 48"; priced separately at $450–$1,200)

• Permit fees (jurisdictional)

• Drainage connection to storm sewer (municipal hookup priced separately)

• Landscape restoration beyond rough grade

• Fence or railing on top of wall (priced separately if required for fall protection on walls over 30")

• Removal of trees or large roots in the wall footprint

This proposal is based on the following assumptions. If any assumption is incorrect, the contract price and schedule are subject to adjustment by Change Order:

• Site access is available during normal working hours (7am–5pm, Monday–Saturday)

• Adequate parking is available within 100 feet of the work area

• Electrical power and potable water are available on-site at no cost to contractor

• Existing structural elements, waste lines, water supply, and electrical service are in serviceable condition unless noted

• {{client_name}} will remove personal property, artwork, and valuables from the work area prior to start

• Work is based on a single mobilization; re-mobilization required due to delays outside contractor's control will be billed at current rates

• Soil behind wall is stable backfill material (not organic or saturated clay)

• 811 verifies no utility conflicts

• Wall is below the 48" engineering threshold, OR {{client_name}} has secured the required engineering stamp

• Site allows access for skid-steer or mini-excavator

Any modification to the scope, specifications, materials, or schedule set forth in this agreement must be authorized in writing as a Change Order signed by both parties before the work is performed. Each Change Order will describe the modified scope, any adjustment to the contract price, and any impact on the schedule. Verbal instructions do not modify this agreement. Additional time and cost associated with unforeseen conditions — including but not limited to concealed rot, asbestos, mold, faulty prior installation, unmarked utilities, or code-required upgrades triggered by the work — will be documented as a Change Order and billed at the rates stated in this proposal or at {{contractor_name}}'s then-current published labor rates, whichever is in effect at the time the condition is discovered.

{{contractor_name}} warrants the workmanship of the installed work for a period of one (1) year from the date of substantial completion. Manufacturer warranties on materials and equipment pass through to {{client_name}} as provided by the manufacturer and are the exclusive source of any material warranty. This warranty does not cover normal wear, abuse, neglect, acts of God, subsequent work performed by others, damage from settlement or movement of the building, or modifications to the installed work performed without written consent. To make a warranty claim, {{client_name}} must notify {{contractor_name}} in writing within thirty (30) days of discovering the alleged defect and allow reasonable access to inspect and repair.

This proposal is valid for 30 days from the proposal date ({{proposal_date}}). Pricing is subject to change after that date due to material market fluctuations and scheduling availability. Acceptance requires signature below and receipt of the deposit amount stated in Payment Terms. Upon acceptance, this proposal, together with any attached specifications and subsequent written Change Orders, constitutes the complete agreement between the parties and supersedes any prior oral or written discussions.
