CONSTRUCTION SEQUENCE:
Refer to the Plan Set for all plans and details which relate to Construction Sequence.
1.
Prior to the beginning of any site work the major features of the construction must be field staked by a licensed surveyor. These include the
building, limits of disturbance, utility lines, and stormwater practices.
2.
Prior to the start of the project, an on-site pre-construction meeting will be held. this will be attended by the project owner, the operator
responsible for complying with the approved construction drawings including the erosion and sediment control (E&SC) plan and details, the
design engineer, the engineer responsible for E&SC monitoring during construction, and town representatives from the engineering department
and code enforcement.
3.
A licensed surveyor must define infrastructure locations, limits of disturbance, stormwater basin limits, and grades in the field prior to start of
any construction. Limits of disturbance shall be marked with the installation of construction fence or approved equal. The extents of the
stormwater management system shall be cordoned off to minimize the disturbance on this area.
4.
Install all perimeter erosion control measures, construction entrance as shown on the Erosion and Sediment Control Plan and the associated
Details. Install silt fencing at the bottom of slopes. The standards established in Part 1.B 1.b of the GP-015-002 included in appendix B of this
SWPPP must be adhered to.
5.
Strip site, clear vegetation, and place topsoil in stockpile locations shown on the plan.
6.
Begin rough grading the site. Contractor to limit exposure of denuded soils by providing temporary stabilization for work areas that will remain
undisturbed for over seven (7) days. Chipped rock that is not suitable to remain on site shall be hauled away and properly disposed of. An area
has been provided for the stockpiling of removed soil and rock which is to be removed from the site.
7.
Begin grading of driveway. The sections of driveway started at the beginning of the work day must be paved and completed by the end of the
day.
8.
Rough grade building.
9.
Begin construction of building.
10. Begin the excavation and installation of the drainage and stormwater management system. Protect trenches and open excavations from
erosion. Entry into the system shall be blocked off until site has reached final stabilization. Once system has been installed, backfill, seed where
necessary, and reinstall measures to cordon off the system from disturbance.
11. During site construction maintain and re-establish as required erosion control and stabilization measures as required by the site plan and
details.
12. Excavate to the sub-grade level. Scarify the existing soil to a depth of 12-inches by rototilling or other means acceptable to the Engineer. Install
all courses of stone as per the specifications given on the Plan.
13. Install base course of Item 4 in all pavement areas. Stabilize all open areas with seed and mulch.
14.
Construct remainder of building, driveway and parking areas. First install curbs, asphalt binder, and concrete sidewalk. Once binder course is
installed, drainage outlet may be unblocked.
15. Backfill curbs, grade, place final soil topping and put in place permanent vegetative cover over all disturbed areas, landscape beds, slopes, etc.
16.
Once site stabilization has taken place (An area shall be considered to have achieved final stabilization when it has a minimum uniform 80%
perennial vegetative cover or other permanent non-vegetative cover with a density sufficient to resist accelerated surface erosion and
subsurface characteristics sufficient to resist sliding and other movements), remove all temporary erosion and sediment controls, unplug the
drainage system to allow runoff to enter the stormwater management system.
Winter Stabilization Notes:
If construction activities are expected to extend into or occur during the winter season the contractor shall anticipate proper stabilization and
sequencing. Construction shall be sequenced such that wherever possible areas of disturbance that can be completed and permanently stabilized
shall be done by applying and establishing permanent vegetative cover before the first frost. Areas subject to temporary disturbance that will not be
worked for an extended period of time shall be treated with temporary seed, mulch, and/or erosion blankets.
