The Contractor shall be aware of the following conditions:

a. Existing conditions: Existence and location of site improvements, utilities, and other

construction indicated as existing are not guaranteed. Before beginning work, investigate and
verify the existence and location of mechanical and electrical systems and other construction
affecting the work. Before construction, verify the location and points of connection of utility
services.

b. Existing utilities: Existence and location of underground and other utilities and construction

indicated as existing are not guaranteed. Before beginning site work, investigate and verify the
existence and location of underground utilities and other construction affecting the work.

1. Before construction, verify the location and invert elevation at points of connection of

sanitary all utilities including sewer, storm sewer, and water-service piping; and
underground electrical services.

2. Furnish location data for work related to project that must be performed by public utilities

serving project site.

c. Acceptance of conditions: Examine substrates, areas, and conditions, for compliance with

requirements for installation tolerances and other conditions affecting performance. Record
observations.

1. Written report: Where a written report listing conditions detrimental to performance of the

work is required by other sections, include the following:

Description of the Work

ii.

List of detrimental conditions, including substrates

iii.

List of unacceptable installation tolerances

iv.

Recommended corrections

2. Verify compatibility with and suitability of substrates, including compatibility with existing

finishes or primers

3. Examine roughing-in for mechanical and electrical systems to verify actual locations of

connections before equipment and fixture installation

4. Examine walls, floors, and roofs for suitable conditions where products and systems are to

be installed

5. Proceed with installation only after unsatisfactory conditions have been corrected

d. Proceeding with the Work indicates acceptance of surfaces and conditions.

1.21.5

Preparation

Prior to starting the work, the Contractor shall comply with the following:

ENERAL

1. Existing utility information: Furnish information to local utility that is necessary to adjust,

move,  or  relocate  existing  utility  structures,  utility  poles,  lines,  services,  or  other  utility
appurtenances  located  in  or  affected  by  construction.  Coordinate  with  authorities  having
jurisdiction.

2. Field Measurements: Take field measurements as required to fit the work properly. Recheck

measurements before installing each product. Where portions of the work are indicated to fit
to other construction, verify dimensions of other construction by field measurements before
fabrication. Coordinate fabrication schedule with construction progress to avoid delaying the
work. Space requirements: Verify space requirements and dimensions of items shown
diagrammatically on the Contract plans.

3. Review of Contract documents and field conditions: Immediately on discovery of the need for

clarification of the Contract documents, submit a request for information to the Engineer.
Include a detailed description of problem encountered, together with recommendations for
changing the Contract documents.

1.21.6

Construction Layout

The Contractor shall comply with the following requirements:

a. Verification: Before proceeding to lay out the work, verify layout information shown on the

Contract plans, in relation to the property survey and existing benchmarks. If discrepancies
are discovered, notify the Engineer promptly.

b. General: Engage a land surveyor and/ or professional Engineer to lay out the work using

accepted surveying practices

1. Establish benchmarks and control points to set lines and levels at each stage of construction

and elsewhere as needed to locate each element of the project

2. Establish dimensions within tolerances indicated. Do not scale the Contract plans to obtain

required dimensions

3. Inform installers of lines and levels to which they must comply

4. Check the location, level, and plumb, of every major element as the Work progresses

5. Notify the Engineer when deviations from required lines and levels exceed allowable

tolerances

6. Close site surveys with an error of closure equal to or less than the standard established by

authorities having jurisdiction

c. Site improvements: Locate and lay out site improvements, including pavements, grading, fill

and topsoil placement, utility slopes, and invert elevations.

d. Building lines and levels: Locate and lay out control lines and levels for structures, building

foundations, column grids, and floor levels, including those required for mechanical and
electrical work. Transfer survey markings and elevations for use with control lines and levels.
Level foundations and piers from two or more locations.

e. Record log: Maintain a log of layout control work. Record deviations from required lines and

levels. Include beginning and ending dates and times of surveys, weather conditions, name
and duty of each survey party member, and types of instruments and tapes used. Make the
log available for reference by the Engineer.

1.21.7

Field Engineering

The Contractor

’s field Engineering shall include the following:

a. Identification: Owner will identify existing benchmarks, control points, and property corners

ENERAL

b. Reference points: Locate existing permanent benchmarks, control points, and similar

reference points before beginning the work. Preserve and protect permanent benchmarks and
control points during construction operations.

1. Do not change or relocate existing benchmarks or control points without prior written

approval of the Engineer.

2. Report lost or destroyed permanent benchmarks or control points promptly.

3. Report the need to relocate permanent benchmarks or control points to the Engineer before

proceeding

4. Replace lost or destroyed permanent benchmarks and control points promptly. Base

replacements on the original survey control points.

c. Benchmarks: Establish and maintain a minimum of three permanent benchmarks on project

site, referenced to data established by survey control points. Comply with authorities having
jurisdiction for type and size of benchmark.

1. Record benchmark locations, with horizontal and vertical data, on project record documents

2. Where the actual location or elevation of layout points cannot be marked, provide temporary

reference points sufficient to locate the work

3. Remove temporary reference points when no longer needed. Restore marked construction

to its original condition

d. Certified survey: On completion of foundation walls, major site improvements, and other work

requiring field-Engineering services, prepare a certified survey showing dimensions, locations,
angles, and elevations of construction and site work

e. Final property survey: Prepare a final property survey showing significant features (real

property) for project. Include on the survey a certification, signed by land surveyor or
professional Engineer, that principal metes, bounds, lines, and levels of project are accurately
positioned as shown on the survey

1. Show boundary lines, monuments, streets, site improvements and utilities, existing

improvements and significant vegetation, adjoining properties, acreage, grade contours,
and the distance and bearing from a site corner to a legal point

2. Recording: At substantial completion, have the final property survey recorded by or with

authorities having jurisdiction as the official property survey.

1.21.8

Installation

The Contractor

’s installation of work shall comply with the following items:

a. General: Locate the work and components of the work accurately, in correct alignment and

elevation, as indicated

1. Make vertical work plumb and make horizontal work level

2. Where space is limited, install components to maximize space available for maintenance

and ease of removal for replacement

3. Conceal pipes, ducts, and wiring in finished areas, unless otherwise indicated

4. Maintain minimum headroom clearance of 2.4 m in spaces without a suspended ceiling

b. Comply with manufacturer's written instructions and recommendations for installing products

in applications indicated

c. Install products at the time and under conditions that will ensure the best possible results.

Maintain conditions required for product performance until substantial completion

d. Conduct construction operations so no part of the work is subjected to damaging operations

or loading in excess of that expected during normal conditions of occupancy
