PART 2 PRODUCTS

MATERIALS

Topsoil:	Excavated material, graded, free of roots, rocks larger than [1] [____] inch ([25] [____] mm), subsoil, debris, and large weeds.

Subsoil:	Excavated material, graded, free of lumps larger than [6] [____] inches ([150] [____] mm), rocks larger than [3] [____] inches ([75] [____] mm), and debris.

Granular Fill: Type [A] [B] [C] [____] specified in Section [________].

PART 3 EXECUTION

EXAMINATION

Verify site conditions under provisions of Section [01039] [________].

Verify that survey benchmark and intended elevations for the Work are as indicated.

PREPARATION

Identify required lines, levels, contours, and datum.

Identify known underground, above ground, and aerial utilities. Stake and flag locations.

Notify [utility company] [________________] to remove [and relocate] utilities.

Protect above and below grade utilities which are to remain.

Protect plant life, lawns, [rock outcropping] and other features remaining as a portion of final landscaping.

Protect bench marks, [existing structures,] [fences,] sidewalks, paving, and curbs from excavation equipment and vehicular traffic.

TOPSOIL EXCAVATION

Excavate topsoil from [areas to be further excavated, re-landscaped, or re-graded] [marked areas] [entire site].

Stockpile in area designated on site. [Remove excess topsoil not being reused, from site.]

****** [OR] ******

Remove from site.

Do not excavate wet topsoil.

Stockpile topsoil to depth not exceeding [8] [____] feet ([2.5] [____] m). [Cover to protect from erosion].

SUBSOIL EXCAVATION

Excavate subsoil from [areas to be further excavated, re-landscaped, or re-graded] [marked areas] [entire site].

Stockpile in area designated on site. [Remove excess subsoil not being reused, from site.]

****** [OR] ******

Remove from site.

Do not excavate wet subsoil.

Stockpile subsoil to depth not exceeding [8] [____] feet ([2.5] [____] m). [Cover to protect from erosion].

When excavation through roots is necessary, perform work by hand and cut roots with sharp axe.

FILLING

Fill areas to contours and elevations with unfrozen materials.

Granular Fill: Place and compact materials in continuous layers not exceeding [6] [8] [____] inches ([150] [200] [____] mm) compacted depth, compacted to [95] [____] percent.

[Subsoil] [and] [Topsoil] Fill: Place and compact material in continuous layers not exceeding [8] [12] [____] inches ([200] [300] [____] mm) compacted depth, compacted to [95] [____] percent.

Maintain optimum moisture content of fill materials to attain required compaction density.

FIELD QUALITY CONTROL

Field [inspection and] testing will be performed under provisions of Section [01400] [________].

Tests and analysis of fill material will be performed in accordance with ANSI/ASTM [D698] [D1557] and with Section [01400] [01410].

Compaction testing will be performed in accordance with [ANSI/ASTM D1556] [ANSI/ASTM D1557] [ANSI/ASTM D698] and with Section [01400] [01410] [________].

If tests indicate Work does not meet specified requirements, remove Work, replace and retest at no cost to Owner.

Frequency of Tests: [________________].
