**SITEWORKS BUILDING & DEVELOPMENT CO.,.****CERTIFICATION      OF PRINCIPAL EXECUTIVE OFFICER**

I, Carl Nurse, certify that:

2.     Based on my knowledge, this report      does not      contain any untrue statement of a material fact or omit to state a material      fact      necessary to make the statements made, in light of the circumstances under      which      such statements were made, not misleading with respect to the period covered      by      this report.

3.     Based on my knowledge, the financial      statements, and other financial information included in this report, fairly      present in all material respects the financial condition, results of operations      and cash flows of the registrant as of, and for, the periods presented in this      report;

4.     The registrant's other certifying      officer and      I are responsible for establishing and maintaining disclosure controls and      procedures (as defined in Exchange Act Rules 13a-15(e)(4) and 15d-15(e)(4))      for      the registrant and have: 

(a)     designed      such      disclosure controls and procedures, or caused such disclosure controls and      procedures to be designed under our supervision, to ensure that material      information relating to the registrant, including its consolidated subsidiaries,      is made known to us by others within those entities, particularly during the      period in which this report is being prepared; 

(b)     evaluated      the      effectiveness of the registrant's disclosure controls and procedures and      presented in this report our conclusions about the effectiveness of the      disclosure controls and procedures, as of the end of the period covered by      this      report based on such evaluation; and 

(c)     disclosed      in this      report any change in the registrant's internal control over financial reporting      that occurred during the registrant's most recent fiscal quarter (the      registrant's fourth fiscal quarter in the case of an annual report) that has      materially affected, or is reasonably likely to materially affect the      registrant's internal control over financial reporting;5.     The registrant's other certifying      officer      and I have disclosed, based on our most recent evaluation of internal control      over financial reporting, to the registrant's auditors and the audit committee      of the registrant's board of directors (or persons performing the equivalent      functions): 

(a)     all      significant      deficiencies and material weaknesses in the design or operation of internal      control over financial reporting which are reasonably likely to adversely affect      the registrant's ability to record, process, summarize and report financial      information; and 

(b)     any      fraud, whether      or not material, that involves management or other employees who have a      significant role in the registrant's internal control over financial reporting.
